JOHN L. WELCH, 0F TRENTON, MISSOURI, AND WILLIAM ALMON WELSH, 0F MINNEAPOLIS, MINNESOTA.

Application filed January 11, 1916. serial No. 71,521.

To all whom z'tmay concern:

Be it known that we, JOHN L. :VELCH and VILLIAM A. VJELOH, citizens of the United States, residing respectively at Trenton and Minneapolis, in the counties of Grundy and-Hennepin, States of Missouri and Minnesota, have invented a new and useful Shocking-Machine, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for receiving bundles from a reaper and binder, the function of the machine forming the subject matter of this application being to receive such bundles and to deposit the same in aproperly formed shock upon the ground. Y

The invention aims to provide novel means for elevating the bundles and for turning the bundles end for end prior to depositing the same in the carrier. v

Another object of the invention is to provide means whereby the carrier will be actuated only when a bundle is elevated.

'A further object of the invention is to provide a novel form of swinging carrier cooperating with a rocking dropper which, in its turn, coacts with the shock forming mechanism. 1 1

A further object of the invention is to provide novel means for mounting and actuating the shock forming mechanism.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

Vith the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

Fig. 9 is a fragmental section showing the means whereby the depository is prevented from tilting downwardly; Fig. 10 is a cross section of the pawl and ratchet portion of Fig. 8; Fig. 11 is a sectional detail showing the spring means for actuating the wings of the depository. V

In carrying out the present invention there is provided a carriage 1 of any desired form. The carriage 1 may be variously constructed to travel along the ground, the carriage in the present embodiment being provided adjacent its forward end with a rotating or swiveled fork 2 carrying a forward ground wheel 3. Mounted upon the carriage 1 adjacent its rear end is an axle 4L supporting rotatably a toothed drive wheel 5. The axle 41 may carry also a lateral supporting wheel 5*.

. Pivoted to the carriage 1 as shownat 6 near to the longitudinal center of the carriage and extended laterally therefrom is a bar 7 adapted to be connected with the frame of a binder (not shown). From the outer end of the bar 7 extends a brace 8 which is adapted to be connected with the trucks of the binder. Extended rearwardly, from the carriage 1 and vpreferably secured detachably thereto is a brace 9, cooperating with the parts-7 and 8 to attach the carriage 1 to a binder of any desired sort.

Supported on the carriage 1 is an upstanding elevator frame 10 embodying a laterally extended arm 11. The elevator frame 10 is sustained upon the carriage 1 by means of a brace 12 extended between the arm 11 and the carriage, and by means of suitable bracing members 14 extended between the carriage and the elevator frame 10. Journaled for rotation in the elevator frame 10 near to its upper end is a top shaft 15, a bottom shaft 16 being mounted in the elevator frame near its lower end. The shafts 15 and 16 carry sprocket wheels 17 about which are trained chains 18 supporting bundle carriers 19. See Fig. 1. Each carrier comprises a body 503 attached to the chains 18, depending arms 50 1, inwardly extended fingers 506 which bear on the frame 10 to prevent a kinking of the chains 18, and bundle retaining hooks 507 on the fingers.

ith a view to actuating the elevator, a sprocket wheel is operatively connected with the drive wheel5 to rotate therewith,- a sprocket chain 21 being trained about the sprocket wheel 20 and about a sprocket wheel 22 secured to a countershaft 23 journaled for rotation in the carriage 1 and disposed transversely of the line of advance of the carriage. he counter shaft 23 is operatively connected with the bottom shaft 16 of the elevator by means of beveled pinions 24.

It will now be understood that if the bundles on the binder are carried by any suitable means into the path of the elements 19, the bundles will be elevated, the elevator comprising the carriers 19 and the sprocket chains 18 being actuated by a driving train embodying the bottom shaft 16, the intermeshing beveled pinions 24, the counter shaft 23, the sprocket chain 21 and the main driving wheel 5.

As shown in Fig. 1, the carriage 1 supports an auxiliary frame 25 sustained by braces 26. A top 27 constitutes a part of the auxiliary frame the top being braced as shown at 28 and being supported as indicated at 29. Depending from the top 27 of the auxiliary frame is an intermediate frame 30, the functions of which will be alluded to hereinafter.

As shown in Fig. 1, a bar 31 extends between the elevator frame 10 and the auxiliary frame 25, the bar being equipped with a plurality of openings 32, any one of which is adapted to receive a pivot element 33, received for adjustment in any one of a se ries of openings 3st formed in the lower end 5 of a swingin upright 35 pivoted at its upper end to a trough-shaped carrier 37 which receives the bundles from the elevator 1'819. At this point it may be observed that the arm 11 carries a hook-shaped reversing element 11 which engages the bundies as they are raised by the elevator 1819 and turns the bundles end for end as they are dropped into the carrier 37. A pair of upwardly converging legs 38 are pivoted as indicated at 39 to the auxiliary frame 25, the upper ends of the legs 38 being pivoted at 40 to the carrier 37 at a point slightly in advance of the center of the carrier. The carrier, having received a bundle, is adapted to be swung in the direction of the arrow A of Fig. 1, and the legs 38 serve to prevent too abrupt a tilting of the carrier and too pronounced a discharge of a bundle therein, as the carrier swings in the direction of the arrow A.

The invention comprises a U-shaped lever 42 fulcrumed as shown at 13 upon the elevator frame 10 and embodying arms 44 and 45, the arm e5 lying in the path of a bundle, as the same is moved upwardly by the carrier 19. A retractile spring 46 forms an operative connection between the U-shaped lever 42 and the elevator frame 10, the function of this spring being to maintain the arm of the lever in a substantially horizontal position and in the path of a bundle which is being elevated by the carrier 19. The upper arm 44: of the U- shaped lever 42 is adapted to be engaged by a spring latch 47 mounted on the elevatorframe 10.

The invention contemplates the use of a flexible element 48, one end of which is secured as shown at 4:9 to the upright 85 which upholds the carrier 37. The flexible element as is looped about a pulley 50 mounted on the member 27 of the auxiliary frame 25, the flexible element as thence being extended forwardly beneath the upper arm 4% of the U-shaped lever 12, thence across pulleys and 51 which may be mounted in the arm 11, the flexible element being connected as shown at to a lever 54: pivoted as shown at 55 to the frame 25. The free, forward end of the lever 54: lies in the path of the member 19 of the elevator as the latter travels downwardly after having discharged the bundles into the carrier 37. A short flexible element 61 forms an operative connection between the lever 5st and a rod 100 which is attached to the U-shaped lever 12.

' Mounted to rock in the intermediate frame 30 and extended longitudinally of the carriage 1 is a shaft 56 to which is secured a dropper denoted generally by the numeral 32, the dropper embodying a center member 57 and side wings 58, the center member and the side wings defining side compartments 59, the rear ends of which are closed by a wall 60.. From the foregoing it will be obvious that the dropper 62 is mounted to rock on an axis substantially parallel to the line of advance of the carriage 1, the swinging movement of the dropper 62 from side to side being limited by contact between the dropper and the intermediate frame 30. YVhen the bundle is elevated by the elements 19, the bundle is engaged by the reversing element ll and is turned end for end, the bundle being deposited into the carrier 87. hen the elements 19 descend along the back of the elevator, the elements 19 engage the levers 54: and tilt the same on its fulcrum 55. The flexible element 4:8 is drawn upon and since this flexible element is connected with the upright 35 which supports the carrier 37, the carrier is swung over in the direction of the arrow A. The bundle which is in the carrier 87 is shot into one side of the dropper 62, the bundle abutting against the end wall of the dropper so as to line up and compact the constituent material of the bundle. The bundles are deposited successively in the side compartments 59 of the dropper, the shaft 56 forming such a mounting for the dropper that the same may tilt laterally first in one direction and then in an opposite directionflthe bundles being placed in a depository, the operation and construction of which will be described hereinafter.

When the U-shaped lever 42 is in the position shown in Fig. 4, that is when the arm 45 of the lever is disposed in a substantially horizontal position, the upper arm 44 of the lever engages with the flexible element 48 and draws upon the same sufficiently to elevate the lever 54 to such an extent that this lever will not be engaged by the elements 19 as the same travel downwardly at the rear of the elevator. Consequently'if no bundle is elevated the machine is not actuated and unnecessary wear upon the parts is eliminated. If, however, a bundle is elevated by the elements 19, when the bundle strikes the arm 45 of the lever 42 it tilts the same upwardly until the arm 44 of the lever engages with the latch 47, the spring 46 being put under tension. Since the arm 44 of the lever 42 has been swung upwardly the slack is let out of the flexible element 48 and thus the free end of the lever 54 is permitted to move downwardly until it lies within the path of the element 19 as the same moves downwardly at the rear of the elevator. When the lever 54 thus is swung downwardly, the short flexible element 61 is drawn upon, and the arm 44 is released from the latch 47, the lever 42 resuming the position shown in Fig. 4, under the action of the spring 46, whereupon the arm 44 of the lever will again take the slack out of the flexible element 48 and elevate the lever 54 so that the same cannot be engaged by the elements 19 as the latter descend. The parts of the structure thus are so positioned that the carrier 37 will not be actuated in the direction of the arrow A, as the next element 19 rises, unless the latter be carrying a bundle. The carrier 37 is swung to its original position, in a direction opposite to that indicated by the arrow A, by a retractile spring 500 which extends between the upright 35 and the elevator frame 10.

As indicated hereinbefore, the dropper 62 rocks on a substantially horizontal axis and places one bundle at a time in a depository. The construction of this depository and its operation will now be set forth in detail. Projecting rearwardly from the carriage 1 are brackets 75 upon which is pivoted as shown at 76, for swinging movement in a vertical plane, the main frame of a depository, the main frame embodying a base bar 77, forwardly projecting guides 78, up-

right standards 79 secured to the ends of the base bar 77 as shown at 80 and transverse braces 81, best shown in Fig. 5, and uniting the standards 79 with the base bar 77. The

depository includes an auxiliary frame which is mounted to move longitudinally of the main frame and is adapted to swing downwardly and rearwardly, along with the main frame. The auxiliary frame comprises a support 82 in the form of a bar, the same being of rectangular cross section and being mounted to reciprocate in the direction of its length without rotation, in a socket 83 which is attached to the rear edge of the base bar 77 of the main frame. The upper end of the support or bar 82 is secured to a downwardly and rearwardly inclined bar 84. Disposed transversely of the bar 84 and attached thereto is a front cross bar 86 carrying at its ends, standards 85 sustained from the cross bar 86 by means of braces 87. Attached to the bar 84 at a point approximately midway between its ends is an intermediate cross bar 88. Secured at their lower ends to the ends of the intermediate cross bar 88 are upwardly extended, retractile springs, the upper ends of which are attached to the standards 79 of the main frame. Secured to the bar 84 near to its rear end is a rear cross bar 90 provided at its ends with standards 91, sustained from the rear cross bar 90 by means of braces 92. The bar 84 carries a downwardly and rearwardly inclined bottom 93, side walls 94 be-v ing connected to the standards 85 and 91, the side walls 94 converging as they extend forwardly. It will now be understood that the auxiliary frame comprises the side walls 94, the bottom 93 and the support 82, the latter being mounted to move vertically in the socket 83 which is attached to the-main frame. The guides 78 of the main frame engage the rear faces of the standards 91 of the auxiliary frame and serve to direct the sliding movement of the latter.

Pivotally connected with the rear'standards 91 are angular hinges 95 carrying angular wings 96, adapted to extend inwardly beyond the side walls 94, as will be understood readily from Fig. 6. The wings 96 are swung inwardly by springs 502 which may be assembled with the cross bar 90. Attached to the wings 96 are laterally projecting brackets 97 assembled with the rear ends of flexible element 98 passed over sheaves 99 mounted on the upper ends of the standards 79 of the main frame, the forward ends of the flexible elements 98 being connected with the braces 28 of the carriage 1. The inner ends of outwardly projecting bars 101 are secured to the front standards 85 of the auxiliary frame. Disposed parallel to the bars 101 are bars 102, spacing blocks 103 being interposed between the outer ends of the bars 101 and 102. The bars 101and 102 lie upon opposite sides of the standards 79 of the main frame and aid in directing the reciprocating movement of the auxiliary frame, rollers 137 being journaled between the outer ends of the bars 101 and 102, these rollers being adapted to engage with the outer edges of the standards 79 of the main frame. J ournaled for rotation in the bars 101 and 102 and in the standards 91 are shafts 104: carrying segments 105 adapted to mesh into racks 106 on the inner faces of the standards 7 9 of the main frame, the segments being provided with arms 138 which work through slots 107 in the side walls 91 of the auxiliary frame.

The invention comprises a core 108 which tapers as it extends forwardly, the core being located within the contour of the receptacle defined by the side walls 9th and the bottom 93. The core 108 is sustained from the frame 27 of the carriage by means of connections 109 and by means of a retractile spring 501 extending between the core 108 and the part 30 of the frame 27. Located in front of the core 108 and suspended from the frame 30 is a division plate 130. Retractile springs .110 extend between the frame 25 of the carriage and the standards 7 9 of the main frame. Secured to the supports 29 on the carriage are resilient latches 111 embodying projections 112 adapted to engage with the bars 101 of the auxiliary frame portion of the depository, as indicated in Fig. 9, the latches terminating in inclined directing ends 113.

The support or bar 82 which carries the auxiliary frame portion of the depository is provided intermediate its ends with a notch 11% with which is engaged a latch 115 pivoted as shown at 110 to the base bar 77 of the main frame, the latch being constrained by' a spring 117 to coact with the notch 114. Pivot-ally assembled with the latch 115 is a connection 118, the rear end of which is pivoted to a vertically swinging lever 119 f'ulcrumed as shown at 120 on a support 121 carried by the base bar 77 of the main frame.

The numeral .12 indicates a hook formed at the rear end of a rod 123 fulcrumed in, and mounted to slide in, an opening 124 in a bar 125 on the main frame work of the carriage. The forward end of the rod 123 is pivoted to a finger 126 projecting laterally from an arm 12'? mounted to swing in a vertical plane on a shaft 128 journaled in a support 129 carried by the conveyer frame 10. The shaft 128 is provided with a hook 130 adapted to engage the arm 127 to move the same under circumstances which will be pointed out hereinafter. Secured to the shaft 128 and located within the contour of the support 129 is a ratchet wheel 131 actuated by a pawl 132 carried by the lower end of the rod 100, there being a spring 133 secured to the support 129 and c oacting with lever 42, the rod 100 is moved in the direction of its length, the pawl 132 is actuated, and the shaft 128 is rotated through the instrumentality of the ratchet wheel 131. hen the shaft 128 is rotated, the hook 130 thereon, engaging behind the arm 127, elevates the arm 127, and consequently the rod 123 carrying the hook 122 is actuated, especial attention being directed to the diagrammatic figure which is numbered 3. Ultimately, the hook 122 comes into contact with the lever 119. After the lever 119 has been actuated by the hook 122, the arm 12? drops downwardly in advance of the hook 130 which constitutes apart of the shaft 128.

When the lever 119 is actuated in the manner hereinbefore set forth, theconnection 118 operates upon the latch 115 and moves the same out of the notch 114 in the support 82 which constitutes a part of the auxiliary frame of the depository. auxiliary frame of the depository now is permitted to drop. The operation of the depository will at this point be suspended temporarily, so far as the dropping action of the auxiliary frame is concerned, but it will be understood from the foregoing that after a predetermined number of bundles latch 115 will be disengaged from the support 82 of the auxiliary frame of the depository, the said frame being permitted to m vedownwardly. The dropper 62, it will be recalled, swings laterally, first in one direction and then in an opposite direction. By this operation, the'bundles are dropped alternately upon the opposite sides The have been delivered to the dropper 62, the

of the plate 136 and the core 108, the brim 1 dles passing into the auxiliary frame of the depository and being shaped up into the form of a shock, by the bottom 93 and the side walls 9%, the angular wings 96 serving to hold the sheaves. in place against endwise movement.

As hereinbefore indicated, after a predeternnned number of bundles have been dethe main frame, comprising the base bar 77 in the standards 7 9 is free to swing downwardly and rearwardly with the point 76 as a fulcrum. When the auxiliary frame moves downwardly, the springs 89 are put under tension and, when the main frame swings downwardly and rearwardly, the springs 110 are put under tension. When the auxiliary frame slides downwardly on the main frame, the segments 105, meshing into the racks 106 on the standards 79 of the main frame swing the arms 138 downwardly onto the sheaves in the depository. When the main frame swings downwardly and rearwardly with the points 76 as fulcrums, the flexible elements 98 are tightened up, the wings 96 are swung outwardly, and the sheaves, in the form of a shock, are deposited on the ground. The springs 110 now react to swing the main frame up into a substantially vertical position, as shown in Fig. 2 and the springs 89 react on the auxiliary frame, to elevate the same until the latches 111 coact with the bars 101 to prevent a downward swinging movement of the main and auxiliary frames. When the auxiliary frame is elevated'in the manner hereinbefore set forth, the support or vbar 82 carried thereby is elevated until the notch 114 is alined with the latch 115, whereupon the latch will engage with the notch and hold the auxiliary frame supported.

In a device of the class described, a supporting structure; a depository comprising a main frame mounted at its lower end on the supporting structure to swing downwardly and rearwardly; an open-top auxiliary frame mounted for right line sliding movement on the main frame in the direction of the length of the main frame and adapted to swing downwardly along with the main frame; means located above the depository for discharging sheaves into the auxiliary frame; a latch mechanism forming an automatic connection between the auxiliary frame and the supporting structure when the main frame and the auxiliary frame are swung upwardly, thereby to prevent the main frame and the auxiliary frame from swinging downwardly and rearwardly; and means for supporting the auxiliary frame with respect to the main frame, thereby to prevent a downward movement of the auxiliary frame and the disengagement of the auxiliary frame from the latch mechanism.

20. In a device of the class described, a supporting structure; a depository embodying a main frame mounted on the supporting structure to swing vertically; spring means for cushioning the downward swinging movement of the main frame; an auxiliary frame slidable upon the main frame; a latch carried by the supporting structure and engaging the auxiliary frame to prevent a downward swinging movement of the main frame, the auxiliary frame being downwardly movable on the main frame to break the hold of the latch on the auxiliary frame; spring means for raising the auxiliary frame on the main frame; releasable latch mechanism coacting with the auxiliary frame to hold the latter elevated; wings pivoted to the outer edges of the auxiliary frame; connections between the wings and the supporting structure whereby the wings will be opened when the main frame swings downwardly; a rack carried by the main frame; and a segment meshing into the rack and carried by the auxiliary frame, the segment having a holding arm operating within the contour of the auxiliary frame as the latter moves downwardly on the main frame.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
