LEWIS 0. CULVER AND JAMES B. WILLS, OF WEST PIT'ISTON, PENNSYLVANIA; SAID WILLS ASSIGNOR T0 SAID CULVER.

TRUCK.

To all whom. it may concern:

Be it known that we, LEWIS O. QULVEI: and. JAMES B. W ILLS, citizens of the United States, residing at West Pittston, in the,

county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Trucks, of which the'following is a specification.

This invention relates to improvements in automobile trucks and more particularly to coal trucks, the primary object being to pro- Vide an improved structure whereby the coal may be elevated to be ejected into a chute so that the coal may be readily passed from the truck without interfering with pedestrians who might be passing while the truck is being unloaded. I

The invention further aims to provide a truck of this character which will include an elevator arranged to derive its power from the driving shaft of the automobile truck so that the coal may be elevated to any desired height, this height being limited only by the size of theelevator.

he invention further aims to provide an automobile truck of this character having its coal compartment arranged to form a coal pocket into which the elevator is placed, the latter being arranged to collapse and be held in inoperative position within the pocket when the elevator-is not'in use.

A further object of the invention is to provide a device of this character which .consists of comparatively few parts and is simple in construction, but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merits thereof, reference is to be had to the following description and accompanying drawings, in

- which Figure 1 is a side elevation of the device constructed in accordance with our inven-' tion, parts being shown in section.

ig. 2 is a transverse section taken on the line 2-2 of Fig. 1. s

Fig. 3 is a section taken on the line 33 of Fig. 1.

Fig. 4 is a frigmentary section taken on .the line 44 of The chassis of the truck .is of ordinary construction but by referring to Fig. 1 it will be noted that the body comprises two separate compartments 1 and 2 with which Specification of Letters Patent.

' the coal is received.

Patented May 18, 1920.

Application filed December 20, 1918. Serial No. 267,730.

These compartments are sufficiently spaced apart to form a relatively wide space between the compartments and this space is utilized as a coal pocket 3 shown to advantage in Fig. 2 of the drawing. This coal pocket is constructed so that it has sloping inclined sides 4 and its bottom is curved as shown whereby the coal may be readily removed in a manner which will presently appear. The ends ofthe compartments 1 and 2'have their end walls provided with openings normally closed by sliding doors 5 each of which is provided with a lift rode connected to a pivoted lever 7, the'latter having a handle 8 whereby the operator may swing the lever to actuate the lift rod for opening either door for permitting the coal to pass from the compartments into the coal pockets 3. The drive shaft 9 of the .automob1le is provided with a relatively long sleeve 10 which projects through the pocket 3 near the lower end there-' a clutch of and this sleeve is provided with element 11 adapted to be engaged by a clutch element 12 carried by the drive shaft 9 so that when the two clutch elements are in engagement the sleeve 10 will be rotated.

An elevator frame is also arranged within the pocket 3 and this frame is constructed so that it will be collapsible as shown. This frame comprises two pairs of pivoted arms 13 and 14, the arms 13 being joined together at their lower ends and pivoted on the shaft pivotally connected to the two shafts 15 and 16, each of the arms 13 of one pair being connected to one of the shafts at one end thereof and each of the arms 14 beingconnected to one of the shafts at the opposite end thereof. Upwardly extending arms 17 and 18, also arranged in pairs are connected at their lower ends to the shafts 15 and 16 at the points at which the upper ends of the lower arms 13 and 14 are connected, the ends of the arms-being overlapped as shown to form a neat and eflic'ient connection. The upper ends of the arms 17 and 18 converge and the arms in each pair are connected together and pivotally iomed to a -central cross shaft 19. It will be readily seen that this construction provides a frame which may be readily collapsed to assume the position shown y dotted lines in Fig. 2 and which may be raised to operative positionthese members is connected to one of the cables 23 both of which are trained over the pulley 23 and wound about a drum 24. A shaft 25 is suitably mounted on one of the compartments 2and the drum 24 is fixed on the shaft 25 and the latter is provided with cranks 26 which may be manually actuated for rotating the drum so that a pull will be exerted on the cables whereby the link 22 will draw the shafts 15 and 16-toWard each other to the position shown by full lines in Fig. 2 for moving the elevator to operative position.

A locking device is employed for maintaining the structure in this position and the same includes the pivoted latch members 27, a pair of which are pivotally mounted as at 28 on each wall of each compartment. The terminals of the latch members are shaped to form hooks 29 adapted to en age theshafts 15 and 16 as shown clearly in ig. 3 of the drawing. A pair of lifting elements 30 is provided for each pair of latches, each lifting member being pivotally connected to one of thelatches as clearly shown in Fig. 3. Each pair of lift members is joined together by a pin 31 upon which is mounted a roller 32. A slidable bar 33 is mounted to slide in supporting members 34 and one of these is provided on each side of the device as shown. Each bar is provided with cam edges 35 over which the roller 32 is adapted to move as the bar is reciprocated. This cam edge on each bar is shaped so that the roller is received in a relatively deep recess when the latches are in locked position and when the bar is reciprocated in either direction, the roller will pass over raised portions which form the cams whereby a pull is exerted on the lift members 30 to raise the latches out of engagement with the shafts 15 and 16 thus unlocking the structure and permitting the frame to collapse. A'hofpp'er 37 is secured, through the medium 0 arms 38, to the upper portion of the frame and this hopper isdisposed to receive the coal from the buckets when the latter are dumped at the top of the. elevator,

the latter moving in the direction indicated it will be dumped into the hopper and the latter has one open end disposed to eject the coal into a conveniently located chute which, of course, will conduct the coal to the point of delivery and which, by virtue of the height of the hopper will be considerably above the sidewalk and therefore will. not interfere with the movement of pedestrians. Itwill be obvious that the arms 13, 14, 17 and 18 may be'increased in length to make the elevator considerably higher if necessary in this manner the chute may be raised considerably higher.

Near the end of each shaft 15 and 16 is a roller 39 and these rollers are adapted to travel over arcuate-trackways 40 which are joined to the compartments 1 and 2 by the supporting members 41 and which hav1e their ends curved upwardly as shown in Fig. 2 to provide seats 43 at the terminals of the trackways for receiving the rollers when the elevator frame is collapsed to the position shown by dotted lines in Fig. 2. This is the position that the device assumes when in operative position and it will be obvious that the entire elevator mechanism may be received within the coal pocket so that it will be inconspicuous and will not require much head room. It will be noted that this arrangement does not occupy much space and doesnot detract,-but very little, from the capacit of the truck for the reason that the coa pocket and the space between the compartments may be filled with the coalwhile the truck is in transit. This coal, in the coal pocket, of course, will be -might be considered to be the preferred or approved form of our invention. We desire it to be understood that we may make such changes in construction, combination and arrangement ofparts, material, dimensions,'

et cetera as may prove expedient and fall within the scope of the appended claims.
