Specification of Letters Patent.

Application filed May 19, 1913. Seria1 No.-768,406.

To all whom it may concern:

Be it known that 1, WILLIAM H. HUNT, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Dumping-Wagons, of which the following isaspecification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to delivery wagons or trucks, and the object thereof is to provide improved means for raising the front end of the bed or body of a vehicle of this class into an elevated position to facilitate the discharge of the contents therefromya further object being to provide an apparatus of the class specified by means of which the front end of the bed or body may be raised to the highest possible angle, with reference to the truck frame, consistent with safety so as to produce a complete and quickdischarge of the contents of said bed or body, a still further object being to provide the bed or body of a vehicle of the class specified with a hinge tail gate and means auto matically operated. for opening said gate at the desired time and for locking said gate when the bed or'body returns to its normal position on the truck frame; and with these and other objects in view the invention consists in a mechanism of the class specified constructed and operating as hereinafter described.

The invention is fully disclosed in the following specification of which the accompanying drawings form apart, in which the separate parts of my invention are designated by suitable reference characters in each of the views, and in which Figure 1 is a side view of a power driven vehicle of the class specified provided with my improvement and showing the front end or body raised as in the operation of discharging the contents thereof;Fig, 2 a similar view but showing a modification of the hoisting apparatus, and showing means whereby the bed or body is given a backward movement in the operation of.

raising the front end thereof,;Fig. 3 is a view similar to Figs. 1 and 2 but showing another modification in the means for raising the front end of the bed or body ;Fig. 4 a partial section on the line 4-4: of Fig.

1'-,Fig. 5 a partial section on the line 5-5 I of Fig. 1 ;-Fig. 6 a rear view of the chassis of the frame and the supplemental truck frame shown in Fig. 2, and showing the bed or body in its normal position and with parts omitted.

The invention described and claimed herein is an improvement on that described and claimed inan application for Letters Patent of the United States filed by me September 11, 1912, Serial No. 719,697, and in the accompanying drawingslhave'shown a power driven vehicle of the class usually employed in the art to which this invention relates, and said vehicle is provided with the usual chassis frame a, a front axle a a rear axle a and front and rear wheels of and a and-in the practice of my invention as shown in Fig. 1, I provide a supplemental truck frame mounted on the chas sis frame and comprising central parallel members 6 which correspond with the side bars'of the chassis frame and outside of which are other parallel side bars b which terminate forwardly of and above the rear wheels a as shown at b, so that the bed or body a of the vehicle will always clear the rear wheels 0?, and. in the construction shown, the bed or body 0 is longer than the chassis frame and supplemental truck frame, and the object of using or employing a supplemental truck frame is to elevate the bed or body which overhangs the rear wheels Patented Sept. v, 1915.

in the usual manner so that in the operation b which is clearly shown in Fig. l in full lines and indicated in dotted lines in Fig. 3, and said. cross bar is provided with raised end blocks 6 on which the bed or body normally rests and on which said bed or body moves on a pivot when the front end thereof is raised.

The bed or body is hinged at d to the supplemental truck frame by means of a pintle rod d mounted transversely of'the supplemental truck frame above the transverse bar 6 and hinged plates (5 connected with the supplemental truck frame, and corresponding hinge plates at connected with the bottom of the bed or body through which said pintle rod passes, and said pintle rod is arranged between the blocks 6 The winding and hoisting mechanismwhich I employ involves the usual transverse Winding shaft e and crank shaft 6 geared in connection, as shown, and the crank shaft 6 is provided with the usual crank 6. These mental truck frame, two of which are employed, and which correspond in position with the side bars of the chassis frame a, are placed inclined. tracks 6 which extend from the front end of the supplemental .truck frame forwardly and upwardly, ap-

proximately to the middle thereof, and on these tracks are mounted a transverse shaft 6 having end rollers e which bear on said tracks or ways, this construction being also similar to that in the application hereinbefore referred to, and. common in other apparatus of this class, and mounted on the shaft 6 inwardly of the side bars b of the supplemental frame, and inwardly of the rollers e is a pair of telescopic arms f only one of which is shown, and another pair of arms 9 are also mounted on said shaft and only one of which is shown, and the connection of the arms f and g with the shaft 6 is a pivot connection the same as in the application hereinbefore referred to, and the connection of said arms with the bed or body is shown in Figs. 1, 4, and 5, and is of the following construction. Secured to the bottom of the bed or body between the bottom side .rails thereof is a pair of longitudinal cleats h, but one of which is shown, and whichmay extend the full length of the bed or body, or which may be of any desired length, and secured to said cleats by means of bolts 71. are side plates hwhich extend below said cleats and which are provided with longitudinal slots 11., and the arms 9 are provided with forked heads 9 through which are passed pins 9 which pass through the slots b and said pins 9 are freely movable longitudinally of said slots.

The arms I are provided with heads f having side ears 7 and a central ear f", and the central ear f is longer than the side ears and enters a corresponding slot or recess h in the cleats h and the object-of which is to brace the arms or the connection thereof with the bed or body against lateral movement in the operation of raising said bed or body. The head 1 is connected with the side plates Ir. by a pin i passed through said side plates and through the ears .7 and f of said arms, and it will be observed that the connection of the arms f of the bed or body is forwardly of the connection with said bed or body of the arms 9.

The arms I are telescopic arms which may be made in any desired manner, but which,

with initial lift devices or apparatus involving link members i arranged in pairs and pivoted inwardly of the bottom side rails of said bed or body and preferably to and inwardly of the cleats h and with which are connected telescopic thrust rods 21 which are pivoted inwardly of the bars 6 of the supplemental truck frame, as indicated at i, and the connections of the links 5 and telescopic thrust rods 11 at i are hinged connections, and connected therewith are link bars 2' also arranged in pairs, and said link bars are connected with the pins g with which the heads 9 of the arms g are connected, as clearly shown in Figs. 1 and 5. i

The bed or body 0 is provided with a tail gate j having a loose hanging connection with said bed or body at j, and pivoted to the bottom side rails of the bed or body, adjacent to the rear end thereof, as shown at 3' are lever arms j with the forward ends of which are connected links i which are pivoted below the bottoms of said side rails, as shown at j, to the blocks 1), and the rear ends of the lever arms 3'' are provided with upwardly directed cam noses j inwardly of which are recesses j adapted to receive pins j on the ends of the tail gate j.

It will be understood that, in practice, chains or similar devices are connected with the transverse shaft (2 and with the winding shaft 6 in the usual manner, said chains being shown in Fig. 3. It will also be observed that the transverse shaft 0 with which the arms f and 7 are connected, in the form of construction shown in Fig. 1, is forward of the transverse center of the bed or body and forward of the winding shaft e, and said shaft is shown in its normal position in dotted lines in Fig. 1. The top walls In the normal position of the parts, the

arms 1 and 9 lie fiat or approximately so in the supplemental truck frame, and the separate parts of the arms f are telescoped together, and the upper ends of the parts which are connected with the shaft e bear on the heads of the parts which are connected with the bedor body, as shown at f in weenie Fig. 4, while the lower ends of the parts of said arms that are connected with the bed or body bear on the shaft 6 The object of making the arms f telescopic is to be able to obtain a short lifting levera when the bed or body is in its normal pos sion, or in other words, provide a short lift under the Road, and by means of i a quicker more effective operaa of said arms i irovided, and this also v.les means whereby the bed or body oe raised to a mu h angle or ation than no otherwise possisaid arms aeration the pins slots a and is movement, link bars acirhaidly the pivotal or hinged ts of the links 2', and the telescopic as 21 being in their fully telescoped posi- 11 take the thrust of this pull and the tendency is for the. links 2' to raise the front end of the bed or body, or help toraise it, and this tendency continues until the front enl of the bed or body, reaches a height at w h one part of the telescopic rodsi moves outwardly with reference to the other parts of'said rods.

it be borne in mind that the initial lifting devices i, i and 2' are not an absolutely essential. element in this construction and may or may not be employed.

the chief difference between the construction shown. in Figs. 2 and 6 and that shown in Figs. 1, f and 5 is in the provision of means whereby the bed or body may be given a horizontal backward movement in the operation of raising said bed or body, whereby a greater overhang of said bed or body is produced in the operation of dumping the contents thereof, and whereby the weight of the bed or body with its load is distributed more evenly over the chassis and on both axles of the vehicle, in the normal position of said bed or body, than is possible with the construction shown in Figs. 1, 4L and 5, a further object of the construction shown in Figs. 2 and 6 being to provide means whereby the center of gravity of the bed or body and its load may be moved backwardly at the beginning of the operation of elevating or raising the front end thereof so as to reduce the power necessary to raise said front end of the bed or body with its load.

The above objects are obtained by providing in the supplemental truck frame, or at the rear end thereof, supplemental truck frame members in which are connected directly with the rear end of the chassis frame,

may o-e opei a.

' the tele employed the as in i copic arms f are of sl htly acrent construction, and the initial hitting mechanism consisting of the parts i, i and t is omitted, and the tracks or ways are extended forwardly beneath the seat body of the chassis, and in this form of construction, a chain or other flexible device at is connected with the front the bed or hotly and with a roller shaft m mounted in or over the front end portion of the supplemental truck frame and by means of which the bed or body may be drawn forward into its normal position, as shown in dotted lines in Fig. 2. v

The construction shown in Fig. 3 is the same as that shown in Fig. 1 except that supplemental inclined tracks or ways n are employed rearwardly of the inclined tracks or ways 6 and which extend downwardly and backwardly between, or inwardly of the rear end portions of the side rails of the chassis frame, and the arms 9' are connected with an independent shaft 0 provided with rollers o movable on the tracks or ways it,

and two sets of winding chains p are employed, both of which are connected with the main winding shaft 0. in this construction the same tail gate mechanism is employed, as in Fig. 1, and in the operation of the winding mechanism, the pins g of the arms 9 are normally in the rear ends of the slots h in the plates 72, and move forwardly in said slots when the arms 7 are raising the bedor body and its load through its initial movement, and when thepins g reach the forward ends of the slots k the arms 9 take the load, and the telescopic arms f begin their movement.
