SPRING DRAFT ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 479,681, dated July 26, 1892.

Application filed February 9, 1892, Serial No. 420,823. (No model.)

To all whom it may concern: bolts 15, extending through the bow and Be it known that 1, JOHN F. TINER, of Labraces, and these lugs are pivotally coupled vernia, in the county of Wilson and State of to the terminal eyes 16 at the rear ends of Texas, have invented a new and Improved the draw-bar frames 17. These frames 17 are Spring Drawing Attachment for Vehicles, of open on top and bottom and are elongated, which the following is a full, clear, and exact as shown in the drawings, the frames having description. near the center the cross-pieces 18, which Myinvention relates to improvements in form abutments for the collars and nuts of drawing attachments for vehicles; and its obthe draw-bars, as described below. to ject is to do away with the ordinary double- In each frame 17 is a draw-bar 19, which extree and provide a simple spring attachment, tends longitudinally through the greater porwhich may be secured to any vehicle, which tion of the frame and projects through the may be used for a one-horse vehicle, but front end of the same, and the rear end of the which is especially adapted for a two-horse draw-baris screw-threaded and provided with I 5 vehicle, which when used on the latter vehia nut 20, which by striking the cross-piece 18 cle prevents the horses from pulling against limits the forward movement of the draw-bar. one another, prevents the pole from swaying The draw-bar has also a collar 21, which is sidewise, enables the vehicle to run easily and preferably square, as shown in Fig. 4, and without jerks, and which is also very much this collar is secured to the draw-bar in front 20 easier for the horses, as the springs used in of the cross-piece 18, and by striking the connection with the attachment absorb the cross-piece it limits the backward movement sudden shocks and vibrations. of the draw-bar.

Near the ends of the bow and secured washers 28 and through the pole 10, and a to the sides thereof and to the braces 12 are wide washer 30 is placed between the upper 50 perforated lugs 14, which are held in place by of the washers 28 and the head of the bolt 29. I00

The arms 27 are braced by the curved braces 31, which are pivoted on the bolt 29 on the under side of the pole 10, and the outer ends of the arms are flattened, as shown at 32, and bolted firmly to the arms 27. The braces may thus swing in unison with the arms, and they will afford a secure support for the same. If desired, the top and bottom of the frame 17 may be covered by a plate 33, thus forming a casein which the draw-bar 19 and spring 22 may work.

It will be seen that the arms 27, while affording supports for the singlctrees 26, will also serve as guides for the spring-frames 17 and the draw-bars 19, and when the horses are secured to the singletrees it will be seen that each horse will be practically independdent of the other, and that when either horse pulls the effect of the pull will be to draw the vehicle forward without throwing the pole sidewise, and it will also be observed that the horses will be enabled to start without jerking the vehicle or without straining themselves, as the drawing strain will first come on the springs 22, which will be compressed until the nuts 20 strike the cross-pieces 18 of the frame 17, after which the load will be carried in the usual way. It will be seen, too, that the moment a horse stops pulling the spring 22 will retract the draw-bar and the singletree, so as to take the slack out of the traces and prevent them from being accidentally unhooked, and they will also prevent the horses from getting their legs over the traces.

Having thus described my invention, I claim as new and desire to secure by Letters Patent '1. The combination, with a pole, of arms having their inner ends pivoted to the pole,

singletrees pivoted on the outer ends of the arms, and an independent and yielding connection between each arm and the bow portion of the pole, substantially as described.

2. The combination, with the vehicle-pole, of oppositely-extending arms pivoted thereon, singletrees pivoted on the outer ends of the arms, swinging open frames pivoted to a support in the rear of the singletrees, and springrepressed draw-bars mounted in the frames and connected with the singletrees and arms, substantially as described.

3. The combination, with the vehicle-pole, of swinging arms mounted thereon and extending on opposite sides the eof, curved braces connected with the arms and pivoted to the under side of the pole, singletrecs carried by the outer ends of the arms, open frames pivoted to a support in the rear of the arms, spring-repressed draw-bars held to slide in the frames and connected with the singletrees and arms, and stops to limit the movements of the draw-bars, substantially as described,

4. A spring drawing attachment for vehicles, consisting of a frame provided with an eye at one end and with a cross-bar near its center, a draw-bar having one end screwthreaded and provided with an eye at its other end and with a collar at its screwthreaded end, a nut on the draw-bar, and a spring surrounding the drawar between one end of the frame and the collar of the drawber, substantially as herein shown and de-
