- To all whom it may-concern:

and effective means for oscillating a frame-- supported body, whereby its load is dumped and the body returned to a loading position upon the frame,- the said body being pivoted intermediate of its length to prevent a pre ponderance of weight at one end.

Specific objects of my invention are to provide a Windlass actuating mechanisma and chain or cable connection between the Windlass and body, whereby said body is positively initially tilt-ed in adumping operation and in a recovery operation to a point where it' will automatically complete either movement by gravity under control of a manually releasable Windlass locking means; to provide a= shiftable guide for the Windlass chain or-cable w-hereby the elevation of the guide is changed relative to the n of the body for effecting a dumping operation anda recovery ope ation of said body. Thus the draft line of the chain with respect to the pivot point of the body is varied, whereby said body may beswung in a dumping operation to a position withirespect to its axis of oscillation to throw the preponderance of load over center in order that the dumping movement may be completed by gravity, the said draft line being thereafter changed to accomplish the same result with respect to a body recovering movement.

With the above and other minor objects in view the invention consists in certain peculiarities of construction and combination of parts as set forth hereinafter with reference to the accompanying drawings and subsequently claimed.

In the drawings Figure 1 represents a partly sectional elevation of a Wagon emibodying the features of IIIY'lIlVGIIlIIOH; the container or body being shown infhll. lines in its dumping position and in: dotted lines in its normal loading position relative to-the frame, the section being indicated line 1--1 of Fig.- 3; Fig. 2, an enlarged-frag mentary partially sectional viewofi wagon frameand body, the body" being shown broken away and contracted in.

Fig; 5,- an enlarged detailed cross-section of alink mechanism for loek ing the hinged doors of the wagon-body; the section being indicated by line 5 5 of Fig. 2.

Referring by characters to the drawin s;

1, 1; represent the side sills of a" wagontrnck, the forward ends of which sills sflp' port the hack and side hoards 2; 2-, respectively of' a seat-box. Ihe truck-frameis mounted upon standard front and rear axle connections carrying the usual wheels; as

shown by dotted lines in- Fig. 1, the-rear axle 3 being shown in full lines in Fig. of the drawings. The truck-frame sills just back of the rear axle 3 carry a trunnion 4, upon which trunnion the rear end of a wagon-body is pivoted, through the medium of body reinforcing straps 5.- The major portion of the wagon-body extends forwardly of its fulcrum point in order that the preponderance of weight thereof will cause said body to rest firmly upon the trucksills, the front head 5 of said body being positioned directly rearward of'tli'e seat-box and clear of the same to permit up ward swin thereof. Attention is also called to the fact that the body is approx i mately equal in width to the distance be tween the truck-frame sills-1', 1, and thus the full capacity of the wagon relative to its running gear is obtained.

The tail end of the body, as shown, is

preferably in the form of an inclined bottom chute tapering upward to the top edge of the horizontally disposed body side walls 7. The forward portion of the body is closed by a pair of hinged and longitudinally disposed loading doors 8, their hinged ends being centrally disposed with relation to the body, while their free edges rest upon the juxtaposed edges of the side walls 7. The tail portion of the body is covered-by a transversely disposed hinged dumping door, which dumping door is formed in two sections 9, 9. The main section 9 is hinged to a. cross-plate 10, while the mouth section 9 a hinged to the edge of the main section, he parts being so arranged to permit a folding action between said sections. Extending upwardly from the rear ends of the truck-frame side sills 1 and offset from said sills and the body is a suitably braced pair of rearwardly inclined struts 11, which struts are cross-connected above the wagonbody by tie-rods 11, 11. The feet of the struts 11, as best shown in Fig. 4, are bowed inwardly and are secured to the side sills by a series of bolts or rivets and the bowed horizontal portion of the strut feet are arranged to rest upon and be supported by the rear axle 3. By this arrangement it may be seen that clearance between the struts is permitted, whereby the wagon-body may swing freely upon its trunnion, the said struts constituting a fixed door suspension frame.

I The terminal tie-rod 11' is connected -to ;the free end of the mouth section 9' of the dumping door by flexible connections in the form of chains 12. By this dumping door connection it is apparent that when the body is tilted to discharge its contents, after a predetermined initial swing of said body, the chains or cables 12 will be drawn taut whereby the gate section 9 will first swing up, followed by a backward fold, which action will finally cause the main door sec tion 9 to also swing open and expose the en tire discharge mouth of the body to permit the flow of the load therefrom.

The above described automatically actuated door mechanism is not claimed herein, in that it constitutes the subject-matter of my application Serial No. 815,861, filed February 2, 1914, as a division of this present application.

Both the longitudinally disposed. loading and the discharging doors are positively locked in their closed positions by mechanism comprising a link 13, the free end of which link is arranged to engage a pro jecting lip 14- that is carried by the related door. The link 13 is hingedly connected to a hand manipulated clamping lever 1.), which lever is pivoted to an eared bracket 15 that extends from the juxtaposed side wall 7 of the wagon body. Hence when the door lip is engaged by the free end of the link, the hand-lever 15 being forced downwardly will cause the pivot point o said link to pass under the fulcrum point of the lever to thus effect a drawing lock upon the edge of the door against the edge of the juxtaposed wagon-body side walls.

Projecting from the bottom of the body 5 and forwardly of its head end, is a pair of downwardly extended arms 16 to the ends of which arms branches of a flexible cable or chain 17 are secured, it being understood that only one of the arms constituting the pair are shown in the accompanying illustrations. This chain or cable 17 is passed over a guide means comprising a shiftable uide-sheave 18, the opposite end of the ca le being connected to a transversely disposed tubular Windlass 19, the ends of which Windlass are mounted in suitable journal boxes 19 that extend from the inner faces of the seat-box side boards 2. Motion is imparted to the Windlass 19 by a ratchet-wheel 20, the same being secured thereto. The ratchet-wheel is rotated by a manually actuated Windlass-lever 21, which lever is loosely mounted upon the Windlass and pivoted to said lever is a spring-pressed winding pawl 22, the same being suitably connected to a hand-lever 22, whereby said pawl is forced into engagement with the teeth of the ratchet-Wheel in opposition to the s rin pressure exerted thereon. This wind assever is adapted to be oscillated back and forth by hand and upon its upward or feed stroke the operator forces the pawl into engagement with the ratchetwheel, whereby the Windlass is caused to be positively intermittently rotated in one direction. The pawl 22 is provided with a locking butt 23, which butt is adapted to enga e the head of a Windlass locking dog 24 when the Windlass-lever is in its normal position of rest at the limit of its movement in one direction, which position is shown in Fig. 2 of the drawings. Hence when the Windlass-lever 21 is in its normal position of rest, in order to positively operate the Windlass, the lever must first be moved up wardly to free its now locked pawl prior to the latter being manually pressed into engagement with the ratchetwheel. By this interlocking connection between the pawl and dog it is apparent that the Windlass feeding pawl 22 is locked and also the locking dog 24. The locking dog 24 is suitably fulcrumed to the juxtaposed side board 2 of the seat-box and its tail end 24 is con nected to a coiled spring 25, whereby the nose of the dog is forced into mesh with the ratchet-wheel teeth. A bell-crank foot lever 26 is also pivoted to the adjacent seat-box side board 2 and said foot lever has one arm connected to the locking dog 2% by a link 26. By this arrangement when the windlass actuating lever 21 has been moved from its initial point of rest to free the head of the locking dog 24 from engagement with the tail of the feed-pawl 22, the operator may release said locking dog by manipulating the bell-crank foot-lever whereby the dog is withdrawn from its ratchet-engagement to thus permit free rotation of the Windlass.

The seat-box back board 2 has secured thereto the legs 27 of an upwardly extended sheave supporting frame, the said legs being provided with slots 27 for the reception of studs 27". The studs 27" are extended from a yoke 28, which yoke comprises a pair of arms that are cross-connected by a shouldered rod 28 upon which rod is loosely mounted the shiftable cable guide sheave 18 previously mentioned. The projecting ends of the yoke tie-rod 28 are secured in connection with the yoke arms by lock nuts 28" as shown, the said ends, together with the tie-rod being adapted to rest in either an upper or lower set of

brackets

29, 29, respectively, the same being carried by the guide sheave supporting frame legs 27. Hence by the above arrangement the guidesheave together with its yoke can be manipulated so as to vary the elevation of the sheave by first lifting the yoke in order to free the tie-rod from the brackets into which it is seated and thereafter swinging said yoke so as to cause the tie-rod to be seated in the opposite pair of brackets. The elevation of this aide-sheave is an important feature of my invention due to the fact that it provides a point of draft for the cable whereby the body in a dumping operation will be lifted positively to a point where it will swing by gravity to complete the dumping operation and this point of draft is then changed to a lower elevation whereby the sheave tie-rod will be seated in the pockets 2!), whereby the body will be oscillated positively in a recovery operation so as to shift the preponderance of the weight thereof with relation to its pivot point, whereby said body will automatically drop to its seat after a positive recovery movement.

It should also be understood that while I have shown as an exemplification of my invention a wagon that is particularly adapted for handling garbage, sand. gravel or like articles, I may, without departing from the spirit of my invention. construct any type of wagon for the various uses wherein any or all of the features of my invention may be applied and I may also utilize the body and its dumping mechanism in connection with a container for cement or other articles requiring a temporary hopper, which hopper must be dumped at predetermined intervals, it being obvious that when the device is utilized in connection with a vehicle of any type it is immaterial whether said vehicle be of the four or twowheel variety.

It should be further understood that, while I have shown as one exemplification of my invention, the body pivoted so as to bring the pre onderance of weight forwardly thereo when said body is empty, that the pivot may, in some cases, be centrally disposed whereby the body is balanced when empty, the load being, under these conditions, arranged to present a prepon derance of Weight forwardly, whereby the action in dumping would be the same as that described in connection with the construction shown in the accompanying drawings.

I claim:

1. In a vehicle having a truck frame, a body pivoted thereon to have a preponderance of Weight at its front end, a forwardly disposed Windlass carried by the truck frame, a sheave-supporting frame extending from the truck intermediate of the windlass and body, a swinging yoke mounted within the frame, a sheave carried by the yoke, means for adjustably locking the yoke with respect to its frame whereby the position of the sheave is varied, and a chain or cable connecting the forward end of the body and Windlass, the chain or cable being adapted to travel over the sheave.
