TRUCK OR TRANSORTING DEVICE.

.Application filed February 27, 1926. Serial No. 91,093.

rlhis invention relates to improvements in trucks or transporting devices and has particular reference to such trucks as are adaptedv for use in transporting type forms from one table or support to another.

' One object of the present invention is to provide simple and eliicient `means whereby the receiving or supporting member of the devices may readily be raised or lowered and maintained in a position substantially parallel with the plane of the top of the frame or body of the truck.

`With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set lforth and pointed out in the claims.

ln .the accompanying drawings;

Figure l is aview in elevation of a truck or carrier illustrating an embodiment `of my invention, and showing the vertically movable table or platform in its raised position;

Figure 2 is a vertical sectional view (partly broken away) .showing positions assumed by the part-s when the table 'orl platform is in lowered position;

Figure 3 is a plan view, the table or platform being removed;

Figures 4 and 5 are enlarged views showing certain details, and

Figure 6 is a view of a modification.

The frame or body of the truck may comprise upper and lower side bars l, 2, end bars 3, 3 and uprights 4. rlhe side and end bars l-3 may be united by permanent corner couplings 5, and with these couplings, the legs or upright 4 are connected; said legs or uprights being also connect-ed with the lower side bars 2, through the medium of couplings 6. Suitable castors 'l' may be provided at the lower ends of the legs or uprights 4. s

Brackets 8 are located on the side bars l adjacent respective ends thereof and provide mountings for the lend portions of transverse shafts or bars 9,9. 0n these shafts, the end portions of the parallel arms 0f bail levers l0 are mounted and said bail lever arms may be secured by means of set screws l1. Levers l2 are also mounted between their ends on the shafts 9 adjacent the connection of the bail lever arms thereto and may be secured to said shafts by set screws 13. The levers l2 are provided each with a linger 14 and these lingers may be provided with rollers 14a to engage lugs or feet I 'l5` which depend from a table or platform 16 disposed over the frame or body of 'the truck. Each of these feet or legs may be provided with a plate 17 to be directly engaged by the rollers of lever lingers 14. rlhese plates'may be held in place. by dowels 18 and one ormore washers 19 may be placed between `said plates and the lower ends of the feet or legs l5 to effect adjustment of the length ofthe latter. l2 is also provided with a toe 20 below the mounting of the lever on shaft 9, and the toes 2() project laterally so that their free end portions will be ydisposed under the Each of the levers parallel arms of the bail lever, in proximity to the connection of said arms with the shaft 9. Screws 21 providedwith lock nuts 22, pass throughthe toes 20 and engage the adjacent bail lever arms. In this manner, there is provided an adjustable operative connection between the bail levers and the levers l2 for causingthe latter to effect the raising or lowering of the table or platform when the bail levers are operated.

Y In` order to insure proper operation of the levers to effect the even vertical movements of the table or platform 16, l provide link connections between the two bail levers l0, 10. In the embodiment of the invention shown in Figures l to 4 inclusive,

the adjacent arms of the respective levers l()k (near each side of the truck) are connected by pivoted links 23, 24, these links being pivotally connected at their outer ends with arms of the respective levers l0, and mounted at their inner ends on a bolt`25. The boss 26 on the link 23 is freely mounted on the bolt, but the boss 2'? on the link 24 may be interiorly threaded to engage a threaded portion 28 on the bolt. A nut 29 is providedV on one end 4of the boltV 25v and, near the other end of said bolt, a collar or head 30 maybelocated to provide an abutment for the boss 26, while a spacer "3l may be disposed between-the two bosses 26 and 27'. Each bolt 25 extends at one end beyond the collar or head 30, and has mounted thereon, a roller 32. The rollers 32 on the respective bolts 25 ride in vertical guideways provided by channel irons 33, each secured at its upper end 'to an upper side bar l of the frame and at its lower end to a lower side bar 2 of the frame, and said vertical guideways 0r channel irons are located midway between the ends of the frame. Each bolt 25 may be formed at the end on which the roller is mounted, to receive a screw-driver or other tool, and the adjacent channel iron 33 may be provided with an opening 33y to acilitate the application of the tool to the olt.

In the embodimentof the invention shown in Figure 6, a single link 34: is employed between each pair of adjacent arms of the respective levers. 'Io facilitate the attachment` of such link, brackets 85., 85 are secured to adjacent` arms of respective levers l0 and provided with lugs .36 to which respective ends of the link 34 are connected.

It is desirable that means be provided to restrain the descent of the table or platform 16, and for this purpose, braking devices may be employed, and in the drawings is shown one embodiment of such braking devices. Brake wheels 3.7 are secured (preterably by set screws 37a) to the respective shafts 9 and a brake band 38 extends from one of these brake wheels to the other. The end port-ions of the brakeV band embrace the respective brake wheels, and to the eXtremities of said band, rods 39 are connected and pass through holes in the band, said rods being threaded to receive nuts 4,0, between which latterand the band, springs 4l are located. i

Having fully described my invention what I claim as new and desire to secure by LettersPatent, is
