SPECIFECATION forming part of Letters Patent No. 376,227, dated January 10. 1888.

Application filed July 14, 1887. Serial No. 244,315. (No model.)

To all whom it may] concern:

Be it known that I, FRANCIS L. BEARD, a citizen of the United States, residing at Pleas` ant Ridge, in the county of Leavenworth and State of Kansas, have invented a new and use ful Improvement; in Bob-Sleds, of which the following is a specification.

My invention relates to Van improvement in bob-sleds; and it consists in certain novel features, fully set forth hereinafter, and specifically pointed out in the appended claim.

In the drawings, Figure l is a perspective view of the sled. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a detail transverse section, w w, Fig. 2. Fig. 4 isa similar view, y y, Fig. 2. Referring by letter to the drawings, A designates thefront sled having theroller-bar a in the front end between the runners, to the center of which is secured the end of the tongue a2 of the sled.

A is a'small platform supported between the said runners by suitable cross-bars.y

B designates the rear sled, having the roller b pivotedbetween the front ends of the runners thereof, and to which is secured the tongue B2, and C designates the ordinary -bench secured rigidly across the said sled in any suitable or preferred manner.

D designates 'a small bearing-plate secured .to theupper side of the platform A', having an opening therein to align with the opening in the platform, and E designates a swinging plate pivoted at the front end to the said platform, and having an opening, e, in the rear end thereof to align with theopenings in the plate D and the platform.

F designates a sleeve secured on the under Side of the short tongue b2, near the center thereof, and G designates a sleeve secured to the underside of the end of thesaid tongue, and the said sleeve is extended up over the upper side of the said tongue to form the guard-plateg.

The said plates and the sleeve on the under side are provided with perforations to align with each other and with the perforation in the end of the said tongue.

I designates the connecting-bar between the i sleds, which is provided at t-he front end with a perforation to align with the perforations in plate and the bearing-plate.

the bearing-plate and in the rear end of the swinging plate E when the front end of the said bar is placed between the saidY swinging The said connecting-bar is bent downwardly in rear of the front sled, and the rear end thereof is passed through the sleeves F and G on the under side of the tongue. A series of perforations are formed in the said rear end ofthe connectingbar to align with the perforationsin the sleeve G and the plate g on the upper side of the tongue,`and through any one ofthe said perforations and the perforations in the said sleeve and plate is passed the bolt K, to secure the tongue b2 to the said connecting-bar.

L designates a bench having a central perforation therein, and through the said perforation and the perforations in the swinging plate E the front end of the connecting-bar, and

lthe bearingplateD is passed the king-bolt M,

to pivot the said bench to the front sled, and also to pivot the front end of the connectingbar to the front sled.

It will readily be seen that by passing the bolt K through different perforations in the connecting-bar any desired length may be had to the sled, and it is often of advantage to be able to alter the said length. The angle z' in the said connectingbar, where it is bent downwardly at the rear end of the front sled, is in such a position that the rear end of the front sled in turning will pass under the said bar. Thus the said bob-sled, constructed as herein described, may be turned within its length, this also being a great advantage.

By using the swinging plate E, herein described, to pass over the front end of the connectingbar while the latter rests on the bearing-.plate D, the king-bolt is relieved of all strain, and the parts areso constructed and arranged as to be easily detached when it is necessary to repair or alter the sled.

It will be seen that thc tongue b2 is very short, being only designed to enable the sleeves F and G to be placed far enough apart to properly brace the connecting-bar. There is ample Vertical play of t-he parts of the sled allowed to enable the same to pass'over very rough ground Without straining or otherwise damaging any of the said parts.

Having thus described my invention, I clairn-- The combination, with the rear sled and the connecting bar I, adjnstably attached 5 thereto, and having a perforation in the front end, of the front sled having the platform A', provided with a perforation, the bearing-plate D, secured on said platform, and having a perforation to align with that in the platform, the 1o swinging plate E, )ivoted to the platform,and having a perforation in its free end, the front end of the connecting-bar I being adapted to be disposed between the bearingplate D and the swinging plate E, with the perforation therein aligned with the perforations in the z Said plates, and the bolt M, passing through the said aligned perforations, substantially as and for the purpose herenbefore speoilied.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in :o presence of two witnesses.

FRANCIS L. HEARD.
