To all whom it may concern: Be it known that l, CHARLns C. ATKIN- soN, a citizen of the United States, residing at Miami in. the county of Dacle and State of Florida, have invented new and useful Improvements in Autotruch Loaders, of

. which the following is a spwification.

This invention relates to an improvecl loading device for motor trucks and is especially designed for loading; logs and heavy articles of similar shape, although it is also applicable to heavy loading in general.

The primary object of the invention is'to proviole a mechanism of simple and economical construction that can he driven from the engine the motor vehicle and 'erably driven from a, shaft actueteol by the engine of the motor vehicle through transmission inechanisrn. WlllCll affords it forward and a reverse motion for driving the re spective clrums- Novel Inechanisinis also provided for guiding and supporting the cables. I

Reference is med-e in the following specification the accompanying'clrewings illustrative of the PZ'QTEKTQCl embodiment of my invention, and in Which Figure l is s top plan view of t e frame of 2L motor vehicle having my invention epplieol, l to;

The numeral 15 designates the drivers seat. The engine of the vehicle drives through the main clutch (not shown the main drive shaft 16 to the transmission mechanism 17 and differential 18 mounted on the rearvanle. Tn the illustrated form of my invention the. trensmissionmechanism 17 is shown as mountecl on the rear axle housing snot in this case the drive for t e loading mechanism is taken'direetly from the main shaft 16 by means of the sprocket Wheel 19 secured thereto, and a sprocket Wheel 20 secured to a counter-shalt 21 ot an auxiliary transmission mechanism A sprocket chain 22 connects the two sprocket wheels 19 and 20. Gear 23 end pin- 1on iZ l-sre also secured the countershatt- 21 1n spaced. relation and intermediate the transverse supporting trame members 25 and so, which ere secured to the side mem-v hers ot the truck frame. The counterehatt 2i antlnn auxiliary shaft 27 are rotatably mounted on these trensvense trainemem bers 25 and ild toy means of detachable hearing plates 28 and 29; An idler pinion 30 is ,mounted on the stnh shaft 31, which is supend the gear is acle-ptecl to meslifvrith the idler wheel 30 in orcler to drive the shaft 2'? in a reverse direction, it loeing iinclerstoocl that the position of the gear set intermeoiate 0:? the 24 and idler 30 will give e neu-i trail or nontriving relation. The gear set is shittecl these vsrious positions of for vvarcl, neutral reverse by oi a forlzecl member 3' opted to engage Within the groove the gear 35.

The memh Which-is shifta 39 L0 detechsh J to the transverse members and 26. The rod 38 is connectecl to the transverse shaft 41 journsllecl o hearings secured to the side members e frame 10., by means i a to '23 portion einhracing theirocl 38 an aclap'tec o engage the heaol formed on one end of the reel arm 4A- secorecl shaft a link which udiinelly inhearings ecured to e'r'ocl 38 secured respectively is pivotallysecured to the arm 44 and. link 42. An operating arm 46 is secured to one end of the transverse shaft 41 and is connected at its opposite end to a pivoted control lever 47 by means of the rod 48.

Two drums designated respectively as 50 and 51 are rotatably mounted on a cylindrical extension of the auxiliary shaft 27.

The drums are formed with end flanged portions 52 and52, the portion 52 having a ratchet wheel 53 detachably secured there to by means of fastening devices 54. A collar 55 is keyed to the shaft 27 adjacent to the flanged portion 52 and ratchet pawls 56 are pivotally mounted thereon by means of the pivot pins 57. Springs 58 secured at one end to the collar 55 are adapted to bear against the pawls 56 in order to maintain" them in engagement with the teeth of the ratchet wheel 53. The collar 55 cooperating with the flanged portion 52 of the drum. 51 is similar to the collar 55 previously described and is keyed to the shaft 27, but

the pawls 56' are pivoted thereto so as to operatively engage the oppositely disposed teeth of the ratchet wheel 53, detachably secured to the flange portion 52'. From. this ratchet construction it will be apparent that one drum will be rotated when the shaft rotates in one direction. while the remaining drum will be rotated :when the shaft moves in the reverse direction.

A cable 60 is wound upon the drum 56 in such direction that the rotation of the drum from the shaft 27 will result in the further winding of the cable on the drum.

A cable 61 is wound upon the drum 51 in such direction that the rotation of said drum through the auxiliary shaft will result in this cable being wound upon the drum. In other words the cables and 61 are wound on their respective drums in opposite direc-. tions; In order to guide the cable 60 so that it may exert a pullin the desired direction.

the projecting portions being provided'with,

aligning apertures for receiving the thread ed ends of the reinforcing rod 69'." A nut 70 secured to the upper threaded end ofsthe rod and a nut 71 secured to the lower thread ed end of the rod maintain saidrod inposition. A tie rod 72 is made in sections adjustably connected together by means of turn buckle 73. One of the apertured ends of the tie rod 72 is interposed. on the rod 69 between the nut 71 and the arm of the angle plate-68. The other end of the tie rod is secured to the channel frame 10 of the truck by suitable fastening devices 74. It will be noted that the cable 60 passes over sheaves 62 and 64k and the free end of the cable is provided with a hook 75 whereby a loop may be formed in one end of the cable for engaging the lo or other object to be loaded. The block %6 preferably in form of a wedge is driven betweenthe bracket 66, and the reinforcing rod 69 in order to maintain said-rod under tension. The pull on the cable 60 and tierod 72 is such as to exert a tensile stress which is resisted by 'the beam and the rod 69. The log 77 is adapted to slide on spaced skids 78'supported by means of inclined posts 80 inserted within the tapered' brackets 81. As shown in the drawings both of the brackets 81 are carried by the frame of the truck. However, it will be understood that one or'both of said brackets may be carried by the frameof a trailer indicatedby the dotted lines 82 in Fig. 1. Ufcourse when the loading operation is first startedthe skids 78 may rest directly upon the body of the truck, but as the load cm the truck increases in height the post 86 may be utilized for liftin one end of the slrids to the desired height. 7 g hen the vehicle is in motion the brackets 66 and 81 are used to support the ordinary staves whieh retain the load upon the body of the vehicle. 1

In operation. thetransmission mechanism of the vehicle is first placed in neutral position, the main clutch bein in driving position so that the engine 0 the vehicle may drive the main shaft 16, but the motion I thereof is not communicated to the rear wheels 83 of the trucln. Motion is transmitted from the shaft 16 to the counter-shaft 21 by means of the sprocket chain 22 and namely. gear 23, idler dfland pinion 34. The 1 gear set 34 and 35 may also be placed in neutral position in which case nofmotion will he communicatedfrom the. counter-shaft 21 to the shaft 27-. i

Assume that theear set is in the neutral position as above escribed.,1The free end of the cable 60] is then pulled so that the cable will unwind from the drum'50 and a loop is formed around a log?! as shown in Figure 23. The gear 35 is then shifted so as to engage pinion 2a and drive the shaft 27 and drum In a forward direction, which results in windingflthe cable 60 on the drum 50 and drawing the log77 up the skids 78 and into the body of the vehicle. While this operation is continuing the free end. of: the cable 61 drawn so asto unwind the same from the drum 51 and attached to the log next to be loaded. It will be seen that this method of operation affords an almost continuous loading operation. WVhen the log 77 has been loaded on the vehicle the gear set 34 and 35 is shifted so as to engage the pinion 77 and drive the drum 51 in a reverse direction, which results in the winding of cable 61 upon the drum and theloading of a second log. While this second log is being loaded the free end of the cable 60 is detached from the log 77 originallv loaded and attached to the third log and so, until the loading of the vehicle is completed.

This invention has been described in connection with a motor vehicle having the transmission mechanism mounted on the rear axle. However, it will be understood that it is equally adapted to motor vehicles utilizing the unit power plant, or having the transmission mechanism located near the center of the vehicle, In such cases, however, the driving mechanism 22 will be modified accordingly and preferably the drive will be taken from the jack shaft which is ordinarily provided in the transmission mechanism of modern motor trucks for actuating auxiliary mechanisms such as a loading device. Other modifications may also become apparent to thoseskilled in the art to which this invention appertains, but all variations in the details of construction of my invention which do not depart from the spirit or'scope of the appended claims are included within the purview thereof.

I claim:

1. The combination with a truck having a frame with a motor mounted therein, of a log loading device, skids for guiding the logs during the loading operation, means for supporting one end of said skids on the truck frame, cables for engaging logs to be successively loaded, a drum for each of said cables, and means driven by said motor for selectively actuating said drums in opposite directions.

2. The combination with a truck having a frame with a motor mounted therein, an auxiliary shaft mounted in said frame having a drum mounted thereon, a sheave pivoted to a side member of said frame, a bracket secured to said frame, a beam mounted in said bracket, a sheave pivoted to one end of said beam, a tie rod connecting the other end of said beam to said frame, a cable passing over said sheave and wound on said drum and means'for driving said auxiliary shaft and drum from said motor.

3. In combination with the frame of a motor truck, a bracket secured tosaid frame, a beam supported in said bracket, angle plates secured to each end of said beam having aligning apertures formed therein, a reinforcing rod passing through said apertures in spaced relation to the bracket, a block interposed between said bracket and rod, a tie rod secured to one of said angle plates and the frame, a sheave pivoted'to the other of said angle plates, a cable passing over said sheave, said sheave and tie rod exerting forces on said angle plates ten ding'to place tension on said reinforcing rod, a drum for winding said cable, and mechanism actuated by the engine of the motor truck for rotating said drum.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
