TRUCK.

Specification of Letters Patent.

Application filed Juli 12, 1911.

Serial No. 638,082.

To aZZ whom it may concern:

Be it lmown thatI, WVALTER J. MoGoY, a citizen of the United States, residing at South Omaha, in the county of Douglas and State of Nebraska, have invented new and useful Improvements in Trucks, of which the following is a specification.

The present invention relates to improvements in trucks for handling boxes, and it has especial reference to box-trucks of the general type shown and described inmy prior Patent No. 993,265. 1

A structural embodiment of the invention is illustrated in the accompanying drawings, whereof i Figure l is a perspective View of the improved truck, Fig. 2 is a side elevation thereof, said figures showing the lever-operated slide inforward position. Fig. 3 is a plan View of said slide, Fig. 4 is a perspective view of the clip connected to the slide, Fig.

Fig. 5 is a fragmental sideelevation of the truck, showing the slide in retracted position, Figs. 6 and 7 are detail views, of a pair of pallets which are employed when the .truck is used for handling bricks.

Referring'to said drawings, 1 designates the square axle of the truck, 2 the wheels which are rotatably fitted on the trunnions 3 on the axlefends and 4the truck frame.

' Saidframe comprises a pair of inclined side beams 5 connected at their upper or rear ends by a cross-bar 6, and adjacent their lower or frOIit, ends to the axle, a pair of rearward extensions? which are formed upon the 2 lower ends of the side bean1s5, and, in turn,

have the handles 8 fastened thereto, and a pair of vertical supports or legs 9. Legs 9 are fastened at their upper ends to beams 5' and their lower ends are oined togetherby a cross-bar 10, the first-mentioned leg ends being attached to said beams at the same point as the frontends of a pair of braces 11 whose rear ends terminate in eyes or collars 12; that are fastened to said handles. To the'upper ends of beams 5 is hinged a load-supporting platform 13 which, in the present instancefconsists of apair of spaced longitudinalsills 14 connected together at intervals by cross-pieces 15, said sills being provided adjacent their upperends' with eyes 16through which the cross-bar 6 passes. Thelower portions of these sills are provided withfL-shaped brackets 17 that are connected with the adjacent cushioning de-v vices 18, said devices being identical in construction with the corresponding parts or elements present in my prior application aboveldentlfied, for which reason they require no description beyond the fact that they include upper and lower plates 19 and 20, and a series of interposed springs 21', the lower plates axle.

Adjacent the wheels, and between the latter and the ends of the beam5, the axle carriesa pair of boxings 22 which are rigidly secured thereto by plates 23 held in place in any suitable manner. These boxes are provided, inaddition to the openings through which the axle ends pass, with- Patented May 28,1912

20 being connected with the transverse passages 24 designed to loosely receive the offset upper ends of a pair of upstanding arms 25 secured to the rear ends of tongues 26. Said tongues are slidably received in grooved guides 27 fixed upon the a I ends of the cross-piece 28fof a fork 29, the

cross-piece having also afiixed to its central portiona lug 30. v To this lug is pivoted the lower end of a link 31,*composed of a pair of counterpart spaced members 32 which diverge toward their lower ends, said members having their upper ends introduced between and pivoted to the lower ends of a pair of spaced arcuate links 33, whose upper ends are pivoted between the apices of a pair of angular brackets 34 arranged in spaced parallel relation to eachother and connected at their rear or upper ends to the central portion of the cross-bar 10.

'Between the upper portionsof the link members 32 is fixed a depending arm 35 to which is connected the forked lower end of the operating lever 36, said lever being provided adjacent its upper end with a series of notches or teeth 37 designed to engage crossbar 10, and at said end with a handle 38.

The lower ends of the sills 14 are provided with L-shaped lifting plates 39, but these are omitted when the truck isusedfor handling brick, in which instance the two pallets 40 and- 41 shown in Figs. 6 and 7 are employed. The first of these pallets replaces the sliding fork and is provided with a central lug 42 and with guides 43 which are identical wit-h the corresponding elements on saidfork. The second, or auxiliary' pallet 41 is adapted to be carried by,

the platform 1 3,and is constructed of adjustably connected parts, so as to enable it' to be fitted to platforms of different w dths; the aforesaid adjustable parts consist, in

the present instance, of a plate or body 44 to whose opposite sides are attached a pair of laterally-flanged or angular members 45 which are formed with slots 46, screw bolts or other suitable fastening devices 47 being passed through said slots and through registering openings in the body 44 to retain said members in adjusted position.

The operation when handling boxes, is substantially as follows :Ihe truck is wheeled close enough to the box to enable the sharpened feet of the lifting plates to be inserted beneath the bottom of the box, the truck having previously been shifted or tilted to bring the supporting platform into vertical posit-ion. The handles are then swung slightly backward to raise up the end of the box engaged by the lifting plates and the lever 36 then forced downward and forward, to move the sliding fork beneath the box. This movement of the lever forces the link 31 and, in consequence, the fork to move forward, as will be understood, and has the further effect of swinging the curved links 33 in the same direction, said lever moving from the position shown in Fig. 5 to that shown in Figs. 1 and 2, in which latter position one of its teeth or notches 37 is engaged by the cross-bar 10, thus locking the leverin place. To withdraw the fork it is only necessary to exert an upward pull upon the lever, whereupon a reverse movement of the latter and of the parts 31 and 33 will take place, such movement being preferably terminated by the contact of the parts 33 with a suitable stop, as, for example, a cross-pin 48 carried by the brackets 34. Practically the same operation takes place when the truck is used for handling brick, the pallets 40 and 41 being employed as above stated.

With reference to the passages 24, through which the offset ends of the arms 25 extend, it may be stated that these passages are sufficiently wide to permit play of said ends forward and backward bodily therein, sidewise play being, however, prevented. This play is necessary in order to enable the fork 29, to remain flat upon the ground until the end of the box has been raised high enough to permit said fork to be forced thereunder without interference on the part of the box end.
