DETACHA'.BLE DRAFT-TONGUE' FOR QUARRY-TRUCKS.

Specification of Letters Patent. Patented Dec. 28, 1909. Application filed April 23, 1909; Serial No. 491,708. 4

To all whom it may concern:

Be it known that I, LOWRY W. STATLER, citizen of the United States, residing at Piqua, in the county of Miami and State of Ohio, have invented certain new and useful Improvements in Detachable Draft-Tongues for Quarry-Trucks, of which the following is a specification.

This invention relates to trucks and more particularly to a truck especially designed for use in stone quarries for conveying blasted rock from the stone ledges to the crushing plant.

The object of the invention is to provide a quarry truck having a novel form of draft tongue capable of being readily attached to either end of the truck so that the latter may be caused to travel in either direction with equal facility.

A further object is to provide a truck in which the tongue attaching members are extended longitudinally beyond the periphery of the adjacent traction wheels thereby to permit the tongue or pole to be readily attached to or detached from the vehicle without the necessity of unhitching the team.

A further object is to provide the draft tongue or pole with depending shoes having curved terminals constituting runners, which latter serve to prevent the double and swingletrees from coming in contact with the ground when transporting the draft tongue from one truck to another.

- A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability, and efficiency.

Further objects and advantages pear in the following description, it being understood that various changes in form, proportions, and minor details of construction may be resorted to within the scope of the appended claims.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a top plan view of a quarry truck constructed in accordance with my invention, the detachable tongue being shown in full lines on one end of the truck and in dotted on the other; Fig. 2 is a perspective view of the rear portion of the tongue will apor draft device detached; Fig. 3 is a side elevation of the forward portion of the truck; Fig. 4 is a top plan view of the truck with the detachable tongue removed; Fig. 5 is a longitudinal sectional view of Fig. 4.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings by the same reference characters.

The improved truck forming the subject matter of the present invention includes front and rear axles 5 and 6 on which are mounted traction wheels 7 said axles being pivotally connected by diagonally disposed braces 8 constituting a short turning gear. Extending laterally from the axles 5 and 6 of the truck, are spaced supporting members or arms 9 having their outer or free ends extended longitudinally beyond the periphery of the adjacent traction wheels for attachment to the draft tongue or pole 10.

Interposed between the front and rear axles of the truck and preferably disposed beneath the diagonal braces 8, are arcuate members 11 having their opposite ends extended beneath the lower faces of the members 9 and to which they are rigidly secured by bolts or similar fastening devices 12. The segmental bars 11 not only assist in supporting the attaching arms 9, but also form the hounds of the truck. The arms 9 are reinforced and strengthened by the provision of metallic plates 13, the free ends of which are bent inwardly and upwardly in spaced relation to the adjacent ends of the arms to form vertically disposed lugs 14, which in conjunction with similar lugs 15 formed on the free ends of attaching plates 16 fastened on the tops of the arms, define sockets 17 for the reception of the cross arm or bar 18 of the draft tongue. The arms 9 are further reinforced and strengthened by inclined braces 19 the ends of which are attached to the inner faces of the adjacent arms, while the middle portion thereof is fastened in any suitable manner to the axle.

Attention is here called to the fact that the inclined braces 19 not only serve to strengthen the arms 9, but also assist in maintaining the latter in parallel relation to each other.

The draft tongue 10 is provided with the usual doubletree 20 and swingletrees 21 for attachment to the draft animals, whereby the truck may be transported from the quarry to the crushing plant.

The cross bar or arm 18 of tllfi dlj itfll tongue is preferably formedof a flat strip of metal, the opposite ends of which are given ahalf turn to produceverticallydisposed p01 7 tions 22 adapted to enter the sockets 17 at the peripheries or fellies of the adjacent traction wheels, the tongue may be readily attached to ordetached from the truck without the necessity of first unhitching the draft animal or animals. n

The opposite ends of the cross bar or arm l 18 a'tthe twisted portions 22 thereof, are extended laterally to produce oppositely disposed loops or finger pieces 23 by means of which. said bar may be readily positioned in I or removed. from the adjacent sockets .17.

Depending from the rear end of the draft tongue 10, preferably beneath the bar 18, are shoes 24, the free ends of which are curved to form runners 25 adapted to travel over the surface of the ground and thus space the tongue from the ground and prevent the double and swingle trees fromcoming in contact therewith when transferring thetongue from one truck to another. 7

Suitable inclined braces 26 are preferably extended from the inner or rear end of the 'track or incline leading tongue to the outer portions of the bar 18, there belng similar inclined braces 27 form- 111g aconnection between the bar 18 and the 'side walls of the tongue 10 in advance of the double-tree 20, as shown.

It is preferred to make the rims of the traction wheels half round in cross section so that said wheels may travel on a concave from the quarry to the plant, the tread surface of the tires being such that the wheels may travel on the bed of the quarry in the usual manner without unnecessary jar or jolting to the contentsof the truck. Thus it will be seen that by graspingthe finger-pieces 23 and exerting a slight upward pull 011 the bar 18, the vertical portions 22 of said bar may be readily disengaged from the sockets 17 so as to permit thetongue to be moved from one end of the truck and placed in position on the other end of the truck or on another truck when necessary. It will also be noted that whenthe tongue is detached from the truck, the curved faces or runners 25 will bear against the ground and support the rear end of the tongue inelevated positionwhile the draft animals are moving the tongue from one truck to another.

Having thus described the inventiomwhat is claimed as new is:

ll lhe combination with a wheeled truck,

attaching arms secured to the axle of the truck and 'having'their free ends projected longitudinally beyond ,the ,peripheral edges iter the sockets fordetachably securing the draft tongue imposition on {the truck.

2. The combination \witha wheeled truck,

spaced arms secured to :the axle ofithe truck and having their free ends projected longitudinally beyond the adjacent traction wheels, a plate secured to one side of each arm and having its free end bent upwardly :to :form a vertically disposed lu'g, a ,plate 7 secured to the top :of each ;arm yandprovided with a similar lug forming in conjunction with the matingluga-socket, a draft tongue detachably secured to the truck and atrans. verse bar carried by the draft tongue and provided with terminal finger-pieces,-the intermediate portions :of :the transverse bar being twisted to produce vertical portions arranged to enter the adj acentjsockets.

3. The combination with a wheeled truck having bounds, the ends ,of avhich are extended beneath and beyond the adjacent aXles, -arms secured ,to the, extended portions of :the adjacent hounds, co-acting plates secured :to each arm and having .their free ends extended longitudinally beyond the; ad-

jacent-traction .wheels and bent upwardly to produce vertically disposed lugs, bracesextending between the @inner :faces of the arms and the adjacent ;aXle, ;a draft tongue transverse =bar secured to .thepinner end of the tongue, and having its opposite ends twisted to form vertical portionsnrranged.

to gfit between the lugs of the-adjacent arms, said cross bar terminating in ;finger-,pieces, and shoes depending having their .lower portions curved laterally to produce bearing surfaces.

4. A draft device for vehicles, comprising a :tongue, a transversely disposed bar secured to one end of the tongue and having itsv opposite ends provided withfinger-pieces, braces extending between the transverse bar and vthe adjacent longitudinal edges of the tongue, and shoes depending from the tongue in advance of the bar and provided with curved contact faces, that portion of the transverse bar near the fingerspieces being twisted to produce vertically idisposed portions forengagement with avehicle.

In testimony whereof I affix my signature in presence of two witnesses.
