This invention relates to an industrial truck capable of engaging and lifting a load,-

transporting it from one location to another and discharging it at the latter position.

One object of the'invention is to prov de an improved truckof this Character having an elevating member capable of moving up-' wardly and downwardly and also laterally relative to the longitudinal axis of the truck,

whereby the picking up of a load and its discharge is greatly facilitated.

Another object of the invention is to provide an improved'industrial truck in which the elevating member is movable along an inclined plane, whereby the load can be discharged in close engagement with an upstanding wall or readily removed therefrom.

Another object 'of the invention 1s to pro- 7 vide-an improved industrial truck in which the. elevating member is movable along an inclinedplane and also laterally relativetc thelongitudinal axis of the truck, whereby loads may be readily discharged in close en- 7 gagement with or removed from lip-standing walls in front of or at one' side of the truck.

A further object of the invention is to provide an improved truck having an elevating member so mounted that loads can be engaged and picked up with great facility and readily discharged in predetermined positions, whereby the storing space may be filled with the maximum number of'loads.

Other objects of the invention will be apparent to those skilled in the art to which my invention relates from the following description taken in connection with the accompanying drawings, wherein Fig.1 is a side elevation of a truck embody- 0 ing my invention.

In the drawings, 1 indicates a. frame mounted on a plurality of wheels, preferably two pairs of wheels 2, 3, either pair of which may be driven. In the preferred form of construction, the frame 1 is constructed to form a main section la and a relatively low section 1?), in which arrangement the-wheels 3 are relatively small so that the driving means, which are mounted in a suitable housing 4,. are operatively connected to the wheels 2. The main frame section 1a includes longitudinal sills 10 from which depend drop plates 5. The low frame section 16 comprises a pair of members 5w (see Fig. 6) connected at their inner ends to the drop plates 5 and bent inwardly at their outer ends so as to lie between the wheels 3 and. connected by an angle bar 6. The horizontal flange 6a of the bar 6 serves as a'jtrack or guide, as will hereafter appear. The housing is connected. with a cradle 7 which supports a motor 8, the motor being connected through a propeller shaft with the driving-means within the housing 4 to drive the wheels 2. The cradle 7 and housing 4 are operatively connected'to the frame 1 by a suspension mechanism, one element thereof being shown at 9; but no claim is made hereinto such'mechanism since the same forms the sub'ect-matter of an application filed by John Hertner, of Cleveland, Ohio, and myself jointly (see Letters Patent No. 1628145).

10 indicates a source of power supply,

preferably comprising electric batteries, en-,

closed in a casing 11 and supported on the frame section 1a and supplying current to, the motor 8. i

12 indicates a pair of uprights supporting below the frame section 14; a pair of brackets 13 and above the frame section a dash 14 and a controller 15. 16 indicates a platform on which the operative stands to operate the truck and its load engaging and carrying member, indicated as an entirety at 17. The platform 16 ismounted on a. shaft 16a, suitably carried by the brackets 13. The controller 15 is operated in the usual manner through an arm 15a and-a link 15?) connected to a hand lever 18 swingabl mounted on i the dash 14. 19 indicates a bra e mechanism comprising a wheel fixed to the extended end of the propeller *shaft and engaged by suitable braking elements 19a. The elements 19a are operated to engage and disengage the wheel by devices 19?), to which a linkage 20 is operatively connected. The linkage 20 is connected with a foot pedal 21 which is associated with the platform 16. 22 indicates a spring connected to the linkage 20 and normally tending to hold the braking elements 19a in engagement with the brake wheel, and the foot pedal in the position. shown in Fig. 1, so that operation of the latter downwardly will release the brake and permit driving of the truck. 23 indicates a switch mechanism interposed in the motor circuit and connected by devices 24 with the linkage 20, so that the circuit will be 0 ened when the brake elements 19a are app ied and closed when the brake elements are released from the brake wheel.

,Either or both pairs of wheels 2, 3, may be steered, but by preference I steer both pairs of wheels to insure turning of the truck in small areas. For this purpose, the wheels 2 are mounted on knuckles 25 and the wheels 3 are mounted on knuckles 26 at the. opposite end of an axle 27, fixed to the undersideof the frame section 16 by angles 27 The wheels 2, 3, are connected for simultaneous steering by devices 28, operated through an arm 29 on the lower end of a steering column 30 having an operating device 31, preferably comprising a handle or tiller.

The load engaging and carrying member 17 is mounted to .move' upwardly and down wardly and also laterally relatively to the longitudinal axis of the frame 1, preferably to either side of such axis,as shown in dotted lines in ig. 2. Several advantages follow from this construction and arrangement, for example, if the truck has been driven up to the position to engage a load and the operative sees that the elevating member is not in proper position or in line with the center of the load, he may shift the member laterally without backing off the truck and making another attempt to drive the truck into proper position. This same operation may be efthis result or manually shifting each load as it is discharged. This construction also permits the loads to be discharged in close engagement with lateral upstanding Walls. I In trucks of this general type, the truck frame is relatively wide at one end to secure stability and to provide ample room for batteries and the traction motor, whereas the load carrying member is relatively narrow so that it may be projected below a skid and then raised. This arrangement prevents the discharge of a load against or the picking up of a load adjacent an upstanding wall except by driving the truck in an endwise directi0n,-but in my present construction, the truck may be driven in a direction parallel to a wall and the load discharged in close engagement therewith or picked up therefrom since the load carrying member may be moved laterally toward the wall and hence discharge the load adjacent thereto or pick the load up from such position. a

My invention may be used to advantage in loading and unloading freight cars and other walled areas, particularly where dunnage is used between the loads and also between the loadsand the walls. To'secure the most advantageous results, the load engaging and carrying member, instead of moving vertically t0 lift a load or discharge it, it is mounted to move in an inclined plane (see Fig. 1), so that in discharging a load it is moved downwardly toward the flooring and also outwardly toward the dunnage with the result that'the latter is engaged and held relatively stationary by the load. By mounting the load engaging and carrying'member to move laterally and also outwardly in the longitudinal plane of the frame 1, it may be operated to advantage under these particular conditions. By proper positioning of the truck, the loads may be discharged in tight engagement with the dunnage to insure maximum loadlng of the freight car or other space and to avoid movementof the loads onerelative to the other While the car is in transit. By reason of this mounting, the unloading of a freight car may be readily effected, since in raising the load engaging member or in moving it laterally inwardly, the load is bodily moved away from the other loads or the adjacent wall.

Of the load engaging and carrying member 17 32 indicates a pair of spaced plates connected together by a plurality of devices, for example, the rods 32a and 32?), a plate 320 and a yoke or brace 32d. The plates 32 are shaped to provide depending legs 32' and ICC the plate 320 and brace 32d are connected to the legs near their lowerfree ends. The rod 32b-serves as a support for a pluralityof L-shaped members 17 their vertical portions depending from the rod 325 and normally resting against the plate 320, so that their horizontal portions may normally extend outwardly in a horizontal direction, whereby, upon the operation of the truck, they ma 'be projected below a load to engage and li it or be removed from below a load when and after the latter is lowered into its discharging position. The L-shaped members 17' may be adjusted along the .support 1ndependently of each other and fixed in their adjusted position in any desired manner. For reasons already set forth, the member 17 is raised and lowered in an inclined plane, preferably approximating an angle of degrees. By preference, the guides, indic'ated at 33, are carried by the inner walls of the plates 32 and engage pairs of rolls 34, 35, mounted on a base member, indicated as an entirety at 36, adapted to be moved preferably by a suitable means, indicated as an entirety at 37. laterall in either direction relative to the longitudmal axis of the frame 1, to the positions shown in dotted lines in Fig. 2. The guides 33 may comprise plates secured to the plates 32 and'having their upper and lower side-edges disposed parallel to each other, the lower edges engaging the rolls 34, 35, and their upper edges engaging rolls 38, mounted on stud shafts 39 extending if laterally from the uprights 41 forming parts ofthe base member 36. 'These latter rolls maintain the load engaging and carryingnected by a rod 326 having a spacing sleeve 32c thereon between the plates to which the plates are secured by nuts 32%, and depending portions 42. The depending portions are connected by transverse plates 43 disposed against the opposite side edges thereof and secured to said portions in any desired manner. 44 indicates angles extending along the inner walls of the plates 40. The angles 44 are secured to a transverse angle 45 and angles 46. The angles 46 support a base plate 47 and the angles 45 and 46 support a pair of transverse plates 48, 49, the purpose of which will later appear. The plates 43 are formed with pairs of aligned openings for shafts 50 on which are loosely mounted rollers 51 engaging the flange 6a or a wear plate thereon; whereas the plates 48, 49, support a pair of shafts 52, on which rollers 53 are loosely mounted. The rollers 53 roll on a in the opposite direction.

track or guide 54extending transversely along and suitably supported by the rear wall of the frame section 1a (see Fig. 3). 55 indicates a guide mounted on the frame section 1a in spaced relation to the track 54, and arranged to be engaged by the rollers 53 toprevent the base member 36 from tip ping upwardly due to the weight of a load on the member 17.

56 indicates as an entirety a means for guiding the base member 36 in its traversing movements. Ofthese means, 57 indicates a transverse plate preferably riveted to the under side of the angle constituting the track 54 and extending outwardly therefrom. Along its free edge, the plate 57 carries a series of up-standing stud shafts 58 disposed in a plane at right angles to the longitudinal axis of the frame 1. Rollers 59 are loosely mounted on the shafts 58' and engage with the inner opposing faces of the plates 48, 49, or wear strips thereon, and co-act therewith to insure the lateral travel or traversing movedicates standards mounted on the base 47 and provided with hollow bosses 113b and inwardly extending casing sections 1130 which -co-operate with casing members 114, 115, to form a housing for a power transmitting v mechanism 116 and gear reductions 117 to be later referred to. The hollow bosses 113?; support the outer ends of shafts 118, which shafts are preferably pressed therein in a well known manner. 119 indicates winding elements, such as sprockets, rotatably mounted on the shafts 118, for chains 119a which wind thereon and therefrom in operating the member 17. The chains may have their inner ends fixed to the sprocketssee Fig. 3. The chains are guided around sprockets 119b, loosely mounted on a shaft 120, supported by the plates 41. The outer portions of the chains run around sprockets,

120a, loosely mounted on a shaft 12%. The

shaft 1206 is suitably-supported at its opposite ends in the plates 32 and extended walls 33a of the guide 33, the free ends of the chains 119a being connected to bars 59 forming parts of a clamping mechanism 60, to

which reference will later be made. By means of these connections, the chains 119a operate to raise the load engaging and carrying member 17 when the sprockets 119 are rotated in one direction and to lower the member 17 when the sprockets are rotated 121 indicates disks also rotat'ably mounted on the shafts 118, the hub of each disk and the hub of the adjacent sprocket 119 being connected,

' formed integrally with boss fitting the bearing opening and secured preferably by clutch elements 121a, whereby operated inwardly, against the tension of the the diskshen rotated-will drive the springs 143, by a wmdmg 144, when the sprockets. 122 indicates webs or walls on the outer ends of the casing sections 115 and having axial openings- 122a forming bearingsfor a driven shaft 123 which projects at its ends through the bearings and carries outwardly thereof pinions'124. The outer ends of the shaft are reduced and rotatably fit openings'formed in the inner ends of the shafts 118, the pinions 124 being preferably the shaft and the center portion of the latter being enlarged to form shoulders that engage the bearing Walls to prevent endwise movement ofthe shaft. The pinions 124 mesh with gears 125 rotatably mounted on stud shafts 125a carried bythe disks and the gears 125 in turn mesh with internal ring gears 126 provided on the inner walls of the-sections 114, wherebya planetary gear reduction is provided between the shaft 123 and each disk 121. 126a indicates a gear fixed to the shaft 123 substantially centrally thereof and in mesh with a pinion 127 fixed to a shaft 128 which is mounted at its ends-"in suitable bearings 128a, The bearings 1280 are mounted in a well known manner in hollow bosses 115a provided on the upper portions of the casing members 115. 129 indicates a gear fixed to the shaft 128 and meshing with a pinion 130 fixed to a shaft 131'mounted in a supplemental or cover section 132. 133 indicates a gear fixed to the shaft131 and meshing with a pinion 134 fixed to a shaft 134a, which is connected (preferablydetachably) at one end to the shaft of a motor 135 arranged to be supplied with current from the batteries 10. The adjacent end of the motor casing removably fits the walls of .an openmg 132a formed in the side wall of the cover section 132, being-held rigidly in such position by a bracket or cradle extending laterally from the cover section 132 and a strap or other clamping device 136 engaging the motor casing and bracket. The other end of the shaft 134a is mounted in suitable bearings in an opening in the adjacent side Wall of thejcover section and extends therethrough and carries on its outer or free end a disk 137, which constitutes one element of a brake 138. The other element of the brake consists of a disk 139 held against rotation by but slidable on aseries of bolts 139a which secure the cover 140 to aplate 141 haying a therein by vthe shoulder of a sleeve secured on the outer end of the shaft 134a by a nut 142, the. latter also securing the brake element 137 to the shaft. The non-rotatable disk 139'is'normally pressed outwardly by a plurality of springs (one being-shown at 143 in Fig. 7) into engagement with the disk 137 to brake it or hold it against rotation. The disk, 139 is formed of soft iron and .is

- providin x'prises a casing 146 secured to an up-standing racket 146a. The bracket is secured to one side of the casing 112 by the bolts or cap screws 146a (see Fig. 9). The casing 146 encloses a pair of switches either of which is opened to break the motor circuit by a device within the casing and operated by 'the rock shaft 147. 148 indicates ,an arm fixed to the rock shaft 147. The limit switch mechanism 145 for the motor 135is operatively connected with the load engaging and carrying member 17 and with one of the driven sprockets 119. By means of theconnections between the switch mechanism and the adjacent sprocket 119, the switch mechanism is operated to stop the motor 135 when the member 17 reaches its limit of movement downwardly; whereas, by means of the connections between the switch mechanism and the load engaging and carrying member 17, the switch mechanism is operated to sto-pthe motor when the member reaches its limit of movement upwardly. These separate connections are required byreason of the fact that the hoist chains 119a are operatively connected to the clamping means, already referred to, audit is desirable to stop the motor when the load engaging and carrying member 17 has moved upwardly a predetermined distance, but if in the downward movement of the member 17 the connections with the switch mechanism were arranged to operate the latter and an obstruction should prevent the complete downward movement of the member 17, then these connections would be ineffective to stop the motor. By separate connections controlled by one o the sprockets 119, or other driven element, I prevent the paying out of the hoist chains 119a beyond a predetermined amount. These operating connections may consist of the following: 148a indicates a link connected at one/end .to the arm 148 and at its opposite end to an arm 148?) fixed to a shaft 1480. 149 indicates an arm fixed to the shaft 1480. .The outer end of the arm 149 p is bifurcated and formed with aligned openings to receive a rotatable plug 149a which is slotted to slidably receive a bar 150. The bar 150 extends downwardly through and slidably fits aligned openings formed in the adjacent casing section 1130. The inner edge or face of the bar 150 is provided with a rack which meshes with a pinion 151 fixed to the hub of the adjacent sprocket 119, whereby the pinion 151 is rotated and the bar moved endwise upwardly or downwardly when the power transmitting mechanism is operated. The upper portion of the bar 150 is provided with an adjustable tappet 152 which serves to engage the arm 149, when member 17 to its lowermost position. 149

indicates a separate arm fixed to the shaft 148c,'its outer end being bifurcated and formed with aligned openings to receive a rotatable plug 149a. The plug 149a is slotted to slidably receive a rod 150 pivotally connected at its lower free end to the ad acent side plate 32 (see Fig. 9), whereby the rod is moved endwise by the member 17. Near its lower end, the rod 150 carries an adjustable tappet152a which, in the upward movement of the member 17 a predetermined distance, is adapted to engage the arm 149' and through it and the connections referred to with the switch mechanism, to open the motor circuit and thus stop the motor 135.

The means 37 for moving-or traversing the base member 36 and parts carried thereby laterally or transversely preferably comprise one or more racks and a pinion engaging each rack. In the present illustrated form of construction I provide two spaced racks 61 on the lower side of the base member' 36 and mount the pinions 61a on the frame section 16. By preference the pinions are power driven by a motor 62, receiving 6 current from the batteries 10. The motor 62 by one 'of the drop plates 5. 73 indicates a is associated with .a casing 63 having at one end suitable gear reduction driven by the shaft of the motor and driving a gear 64 (see Fig. 11) and having at its other end a gear train for driving the'pinions 61a. The

shaft for the motor 62 is extended and provided with a member with which a magnetic controlled brake element engages. The member and elements and the control devices for the latter are mounted in a housing 63 and are preferably similar to like elements and parts shown in Fig. 7. The casing 63 is provided with feet or standards 63a resting on cross pieces 63?) carried by the. frame section 16 (see Fig. 3) The gear 64 is keyed to a shaft 65-having a pinion 66. The pinion 66 drives a gear 67 mounted in the casing walls and having fixed to it a pinion 68 in mesh with a gear 69. The gear 69 is fixed to a shaft 7 O which extends beyond the walls of the casing and carries thepinion 61a. This arrangement provides for the positive driving of the pinions 61a at the same speed.

71 indicates a casing'containing pairs of contacts, one of which is opened to break the circuit to the motor 62 when the base member 36 reaches a predetermined position in movinglaterally in either direction. The casing 71 is mounted on an angle 72 carried rock shaft carrying within the casingv de= vices to control the opening of either pair ofcontacts. On itsouter end, the shaft 73fis provided with an arm 74 to which is pivoted one end of a-link 75. The opposite end of the link 75 is pivotally connected to an arm 76 fixed to 'a shaft 77. The opposite ends of the shaft 77 are suitably supported by brackets 77a preferably secured to the cove ers'or end walls of the casing 63 and extend-. ing to one side thereof. 78 indicates a separate arm carried by the shaft 77 and carrying a link 79 pivotally connected to a cross head 80. The cross head 80 is formed with an opening through which slides a rod 81 supported at its opposite ends by suitable brackets 81a extending from the free ends of the adjacent rack 61. Near its opposite ends, the rod 81 carries adjustable tappets 82, each arranged to engage the cross head when the base member 36 is moved laterally and through such cross head, link 79, arm 78, shaft 77, arm 76 and link 75 to operate the srvitch mechanism and thus stop the motor 6 The clamping means 60 are arranged to engage the upper portion of the load and maintain it on the load engaging and carrying member 17 While the load is in transit-and While it is being moved upwardly and downwardly. As shown, the'raising and lowering means 112 is interconnected with the clamping means 60 so that the latter is first operated to clamp the load in the operation of picking it up, and in discharging a load, the 100 engagement of the load with its support in paying out the chains serves to effect automatic release of the clamping means from the load. The bars 59 are mounted attheir inner ends on stud shafts 83 mounted on the inner 0 walls of the plates 32 and carry at their outer ends a clamping member 84, such ends being preferably pivoted to up-standing ears 84a. The bars 59 and ears 84a are formed with series of openings to permit of adjustment of 9 tained in an in-operative position, that is, an elevated posltion, against a stop 84', to

permit the elements 17 to be projected below the load with the clamping member above it; The clamping'member 84 is preferably held in elevated position by one or more sets of 2 devices 85, each set comprising the following: 85a indicates a yoke member pivoted at one end to the adjacent bar 59'. The yoke member straddles a compression spring 856 and its opposite end is bent to form a seat 850 for one 125 end of the spring 85?). 86 indicates a rod suitably fixed to and depending from a cross member 86a rotatably supported atits oppositeends in theplates 32 near their upper ends. 'Th'e'i'odl8 6 extends through an open; 9.

ing formed in the seat 850 (being guided by the walls of the opening) and carries at its free end a collar 866 which forms a seat for to operate the clamping member 84 as lift-' ing of the load takes place, and thus clamp the load on the member 17.

8400 indicates a stop to limit movement of the arms 59 downwardly and thus enable the raising and lowering means to be effective where the load is not large enough to be clamped by the member 84.

From the foregoingdescription it will be seen that I have provided an elevating member capable of moving upwardly and downwardly and that such member is mounted on a transversely movable carriage, making it possible to move such member or a load thereon upwardly and downwardly and also laterally, whereby such member may be readily moved or adjusted into operative relationshi to a load or the support or devices on whicii a load is to be discharged. This form of construction permits the load engaging member to be moved laterally when in its lowermost position (see dotted lines on the lower side of Fig. 2) or when in its raised position (see dotted lines on the upper side of Fig. 2) or when in any intermediate position.

It will also be seen that the construction is relatively simple and easily controlled. In the illustrated construction, the drivers station is at the outer end of the frame section la and adjacent thereto'I provide a controller 87 having a handle 87a for operating the motor 135 and a handle 88 connected by a shaft 90 to a controller 91 for operating the motor 62. By operating both controllers 87 and 91, the elevating member 17 may be operated upwardly or downwardly and laterally simultaneously.

To those skilled inthe art to which my invention relates, many changes in construction and widely differing embodiments and applications thereof will suggest. themselves without departing from the spirit and scope of the invention.
