F ig. l() is an elevation showing my invention applied to a truck having a plurality of removable bodies thereon.

Referring to Fig. l, A represents the loading platform against which the truck, represented generally by B, may be backed in order that theremovable body C may be rolled from oil' the truck onto the platform. The platform atits forward edge is provided with the recess l, upon the bottom of which is placed the metal plate 2, to prevent undue wear upon the material at the bottom of the recess. lt will be noted that this plate 2 is formed at its forward portion with the downwardly extending flange 3, thus providing a structure that will readily guide the beveled end 1lat the rear of the chassis frame into position so that the track upon which the body wheels roll will be in proper alinement with the upper surface of the platform A. The truck is of the usual type comprising the customary wheels 5 and drivers seat 6,

lReferring to Figs. 2 and 3, the upper portion of the chassis frame 7v has secured thereon a track comprisingthe rails 8, which rails, as will be noted, are provided upc; each side of each thereof with the opstanding flange v9, and the fiat web portion lll. rlhese rails are also outwardly flared at their rear ends as indicated at ll (see Fig, 2) for the purpose of more readily guiding1 the body wheels into proper position when loading the body ontcjythe frame. seen in Fig. 3, the remoiable body4 is provided on its under surface with a plurality of wheels 12, which wheels are suitably jourualed in the boxes 49 (best seen in Fig. 5) which will be more fully described later. The floor of the body is designated at la, and is braced by suitable cross braces 15 and the longitudinal beams 16, against the under faces of the latter of which extends from end to end of the body flat metal plates l?, the function of which is to greatly increase the rigidity of the body. As seen in Fig. 3the rails 8 are secured upon the beams 18, which are in turn mounted upon. the upper surface of the chassis frame 7. As pointed out above, the rear end of the chassis frame at each side and directly under the rails, is provided with the bevel d to aline the rails 8 with the upper surface of the platform.

Referring to 2, it'will be seen that adjacent the rear end of the chassis frame located` a structural frame work, comprising the cross beam 19, and the longitudinallylextending beams 20 vand 21 extending from the cross beam 19 to the end beam 22. lilithin this structural frame work is suitably mounted the mechanism for moving the body longitudinally of the chassis frame, and which mechanism will now be described. It will first, however, bepointed out that eX- tending longitudinally and centrally of the underneath side of the body and projecting a substantial distance from the front end thereof is the 'straight rack 23 (see Fig. Li) which raclr is driven .by the main driving gear 2d see Fig, Power for driving the gear. 2d is supplied by a crank applied to the end 25 of the shaft 2G (see Fig. 2) which shaft extends a suitable distfmoe through the. side of the chassis frame, and is mounted at its outer end in the bracket 27. Upon the inner end of the shaft 'ZG is fixed 'the pinion 27, which pinion in turn meshes with the gear wheel 28 suitably keyed to the shaft 29, which shaft is journaled adjacent its ends in the beams 20 and 2l. Also keyed to rotate with the shaft 29 and approximately midway between the beams 2G and 2l is the pinion 30, which pinion meshes with the main drive gear 24 to impart rotation. thereto. It will thus be seen that hy rotation of a crank upon the outer end :25 of the shaft 26, rotation will be iinparted through the train of gears just described to the drive gear 24, which will in turn drive the rack 23 and cause the body C to move longitudinally in the desired direction along the track 8. rhe rack 23 and gear 2d are each provided with. a shroud 'to prevent crowding of the teeth.

lin loading and unloading thesekbodies Onto or from the truck frame, it may often occur that there will be uneven places i n the pavement upon which the truck wheels rest, or that one platform may be slightly higher than another, -both of which features, to gether with others not mentioned, ina cause the drive gear 2l to assume various ieights with relation te the rack 23, thus making it possible Ythat if such differences in height were very great, trie drive gear 2i might be thrown entirely out of engagement with the :rack 23. .ln order t@ enable the drive gear d to he made to mesh with the rack 23 at all times, and in all vertical positions of the rack 2S, l have provided a novel adjusting means which 'if will nolw describe.

Referring 'to Fig. 6, the drive gear 24 is mounted upon the shaft 31 shown in dotted ,on eachside of the drive gear 2l. These sector arms are in' tiirn rotatably mounted upon the shaft 29 and at each side of the pinion 3G. Formed upon the outer face of ite ""hrtnigh the side t the sector and t'or the greater lenmth et their lower portion are the teeth l n in turn mesh. with the pin! n pinions are suitably keyed ilse keyed to the shaft 35 is 3G, which in turn meshes 31?' mounted upon the Shaft lit siown in Fig. 2 extends the chassis frame, and is supported at its outer end in the bracket 'l-ie outer end ot the shaft 38 is formed with a squared or otherwise suitahiy d l 2G upon which may be I. .2 willen h LU' engligement a cranlt hanto met used for driving the i tach the saine crank` may be interchangeafbly upon each of the ends 25 andai-59. lit will lus be seen that as the shaft 38 is rotated by this crank arm, mo-

tion will he in tried through the pinion 3'? and 36 the pinions 34, the rotation oit f ich will cause the sector arm 32 t@ elevated or lowered` according to the direc.. oil rotation ot the crank handle. r@ance the 24 as stated above has its shaft,

secured at its enter end the Finse upon the inner end of 0 and in position to engage the the pat/vl 42, which as shown in suitably termed at its end to come into loeltinp; engagement with the teeth ot the This pawl is held in locking engagement with the pinion teeth. by the prinp; which encircles and is suitcr, t ably secured upon' the shaft 40, and to remove the pawl 42 from engagement with the pinion 3'?, it l.will be necessary to overcome the tension in the spring` by appro priate movement of the handle 41. This I av/l will be held out of engagement with pinion 3"? during the time which is required for the vertical adjustment of the drive gear 24, y will he released and the pawl 42 will assume its locking; engagement with the pinion 37, thus turn insuring that the gear will be held at the proper elevation to ei'ieetively 'mesh with t` roch 23 on the underside of order to relieve any twisting which the handle 4l fains the elevation or depression of the drive gear 24, there. are provided two of the sector arms 3:2 located one on each side ot the drive gear 24.

lin order to hold securel the body from any vertical movement witi relation to the frame after being placed in its inal posi tion, there are provided the tapered rearwardly extending hooks 44, 45, 4G and 4'? (see lig. 2) the former two orp which are located adjacent the front end ot' the chassis Jframe, and the latter two of which are located adjacent the rear end oit' the same.

-t'eterring to F 3 and 5, it will be seen that-these hooks are formed to engage with the perforated ears 48 upon the forward longitudinal movement of the body. rEhe ears 48 are preferably formed integral with the lower portion of one ofthe journalv boxes 49, in which journal boxes rotate the axles 50 of the wheels 1:2. lt will thus be seen that as the body moves through the last few inches ot' its travel toward its final position, the hooks 44, 45, 46 and 4'? will enter the 'perforated ears 48, and thus hold the body securely against any vertical movement with relation to the chassis trame.. lt is to be especially noted in connection. with the hooks 44 and 45, that they are located one on the outside of one ot the rails and the other on the inside ot the other ot the rails., and that the rear hooks 4G and 47 are -located on the opposite side ot the respective rails, the purpose tor which is to permit the oars 48, which are to engage with the hooks 44 and 45, to pass the hoolrs and 47 while the ears are traversing this particular part of the track, thus eliminating the danger ot' the ears for the front hooks coming into engagement with the rear hooks while they are passing the saine. The hooks as shown are secured in position by suitable fastening; means, such as bolts or the like, indicated at 51.

l will now describe the locking means provided for preventing an. Y rearward movement oit the body after eing placed in proper posit/ion upon the tr ck. Secured to the under side ot the cross 'beam 52 are the straps 53 (see Figs. 4 and 9) which straps arebent to provide the suitable eye lets 54, in which eyelets are Xedly held the short rods 55; there beingA one of these rods lined upon eachside of the rac-k 23, as

shown in Fig. 4, and as also seen in this igure the rods 55 are so positioned. in the ears 54 that they will present the extending portions 56 beyond the outer ear 54. Secured upon the vupper side of each of the track rails 8, and as best seen in Figs; 2 and 8, are the straps 57, which straps are bent back upon themselves to torni the eyelets 58, in which eyelets are journaled at its respective ends the shaft 59, which as shown entends across from one rail to the other 59 bracket 70.

vte

at their forward ends. Keyed to rotate with the shaft 59 and adjacent one end thereof is the bell crank 60 best seen in Fig. 9, and which bell crank comprises the two arms 61 and 62. The arm 61 is formed at its upper outer corner into the hook 63, and at its extreme outer end into the beveled plain surface 64, which plain surface, as shown in Fig. 9, is formed with an upward inclinationftoward the front end of the truck.

As the projection 56 ofthe stub shaft 55 moves forwardly with the body, it will ride over the beveled surface 64,4and thus depress the arm 61 of the bell crank, which after the end 56 has passed thereby will fly upwardly under the action of the spring to be later described, and ythus cause the hook GB to come into engagement with the eXtension 5G, and lock the body against any rearward movement with relation to the chassis frame. Upon the end of the shaft 59 opposite from the bell crank 60 is provided a locking device 65 similar to that just described, with the exception that the' arm 62 of the bell cranlt has been omitted, the structure otherwise being the same as that described in connection with the arm 61.A

The provision of one ofthese locking devices upon each side insures a more perfect and positive iock than' if only one were used. n

Connected to the lower end of the arm 62 of the bell crank (3d-by avpin'joint is the rod 66, which as' seen in Figs. 2 and 3, extendsl rearwardly through suitable apertures in the beams 18 to aipoint closely adjacent the operating shafts 26 and 38. At its rear end the rod 66 is pivoted lto the inner end of the handle 67, which handle is pivoted at 68 in a suitable manner frame 7. The rod G6 towards its frontend has fixed thereon the collar 69, which collar in turn abuts against the bracket 7), through the upper end of slidably passes. Encircling the rod 66 and located between the collar 69 and the plate 71 the coil spring 72, the function of which is to impel the rod (3G in the rearward direction, and thus hold the collar 69 against the By this arrangement it will be seen that upon movingr the outer end of the lever 67 rearwardly, the rod` 66 will be moved for-` wardly against'the tension of the spring 72, and the hook 63 will in turn be lowered in an obvious manner to free the projection 56, and thus permit the body to be moved longitudinally of the chassis frame. Immediately upon the release of the handle 67, the rod '66 under will be moved rearwardly and'return the hook 63 into its locking position, so that when a body is again moved forwardly on the chassis frame, it will be locked in p osito the chassis which bracket the-rod the action of the spring 72 tion immediately upon the passing ofthe extension 56 over the bevel face 6ft, and into engagement. with the hook 63, this hook under the action of the spring 7'2, immediately flying upwardly as soon as passed by the extension 5G. An important feature in connection with this locking arrangement is that the handle 67 forv operating the same is positioned. closely adjacent the ends 25 and 39 of the operating shafts 26 and 38 respectively, whereby the operator-may stand in osition to turn the cranks upon the ends of the shafts 26 and 39 and without moving his position may grasp the handle 67 to free the locking device at the front; thus eliminating any necessity of the operator leaving the position from where he operates the mechanism to move the body on the frame, and have to walk around the front end of the truck in order to release the locking' mechanism.

It often occurs a single load may have that different portions of to be delivered at dif- -ferent destinations, which if only a single body were used would necessitate the standing idle of the truck while thisl fractional part of the load were being removed. ln order to eliminate this loss-of time, I have provided an arrangement which7 as seen in Fig. 10, comprises the use of a plurality of of additional hooks and perto prevent the bodies from moving in a vertical direction with rela-- tion to the chassis frame. Another valuv able feature of this use of a plurality of smaller bodies on a single trip is that oftenn timesgthe available space in a warehouse or theifke through which one of the bodies will haveto be rolled is so small and necessitates such short turns as would be embarrassing were a long body being manipulated in such confined quarters. By providing of shorterbodies, they each be very readily manipulated in a very small space.

and the further provision of the neca plurality f As shown in Figs. l and 10, an opening is provided in the rear of the seat 6 into which the projectingl end of the rack 23 may pass when the body is in its forward position.
