CHRIS EGELAND, OF STOUGHTON, WISCONSIN, ASSIGNOR TO STOUGrI-ITON WAGON COMPANY, OF STOUGI-ITON, WISCONSIN, A CORPORATION OF WISCONSIN.

BOB-SLED.

To all whom it may concern:

Be it known that I, CHRIS EGELAND, a citizen of the Unitetl States, residing at Stoughton, county of Dane, and State of \Visconsin, have invented new and useful Improvements in Bob-Sleds, of which the following is a specification.

My invention relates to improvements in that class of bob sleds for which Letters Patent of the United States, Number (312,385, were issued to the Stoughton Wagon Company as the assignee of Nels Halvorsen, October 11th, 1898, and it pertains more especially, among other things, to the means for connecting the beam and hounds of the sled with the roller of the tongue. By the construction shown in said patent, the. beam is connected with the tongue of the sled by a flexible member which serves to communicate a forward motion only from the tongue to the beam, while by my present construction, a rigid bar is substituted for said flexible connection, which rigid bar performs the two-fold function of a draw bar for communicating a forward movement from the tongue to the beam and hounds of the bob, and as a brace to resist the forward strain upon the beam, both when a load is being held back on a downgrade and when areal-ward movement is being applied to the tongue in backing the bob,

whereby the forward strain upon the knees and beam of the bob is reduced to the minimum.

My invention is further explained by ref erence to the accompanying drawings, in which I Figure 1 represents a side view, part in section, and Figs. 2 and 3 are top views showing modified forms of hounds.

Like parts are identified by the same reference numerals throughout the several views.

The runners 1, 1, beam 2, beam supporting knees 8, hounds 42, supported from the beam 2, tongue 6 and tongue supporting roller 7, are all substantially of ordinary construction. The bar 8 is rigidly connected at one end to the beam 2- through a plate 9, hounds 4 and bolts 10 and 10, and at its opposite end to the tongue roller 7 by a flexible connection comprising the eye-plate l2 and hook 13. The eye-plate 12 is preferably connected at one end with the bar 8 by a plu- Specification of Letters Patent. I Patented 0 12 1915.

Serial No. 686,496.

rality of bolts 14, and at its opposite end with the roller 7 through said hook 13, while the hook 13 is connected with the roller 7 by the bolts 15 and 15.

16 is a bolster which is rigidly connected with the reach 17 by the connecting plates 18, plate retaining bolts 19, connecting strap 20 and nuts 21,,whereby the bolster is always rigidly retained at right angles to the reach.

It will be understood that the hook 13 and eye-plate 1:2 form a flexible connection which permits the roller 7 to be revolved a partial revolution with its supporting trunnions 22, 22 as the front end of the tongue is raised and lowered.

It will be obvious that owing to the fact that the beam and roller tongue are connected together by a rigid member, any rearward movement, applied to the tongue when backing will be communicated from the tongue through such rigid member to the beam and thence to the rear bob, not shown, through the reach 17. It will also be obvious that while a chain or other flexible connection will serve to communicate a forward movement from the tongue to the beam and from thence to the load, such flexible connection would serve no useful purpose whatever when backing the sled or to resist a forward movement of the load when the same is moving down a steep incline.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a bob sled, the combination of a connecting bar having its rear end rigidly connected with the sled beam, the upper surface of said bar being slightly below the upper surface of said beam, a plate rigidly connected with the front end of said bar pro vided with an aperture, a vertical member rigidly connected with the rear end of the tongue of said sled, and extending vertically through said aperture, and a plate rigidly connected at two opposing sides with said beam and at its front side with said connecting bar, all substantially as and for the purpose specified.

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