NITED STATES PATENT OFFIoE.

JOHN ROBERT MCLAREN, JR, OF MONTREAL, QUEBEC, GANADA.

TOBOGGAN.

SPECIFICATION forming part of Letters Patent No. 336,882, dated February 23, 1886.

Application filed January 19, 1886. Serial No. 189,050. (No model.) Patented in Canada December 522, 1885, No. 23,039.

To all whom, it may concern:

Be it known that I, JOHN ROBERT Mc- LAREN, Jr., of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have invented certain new and useful Improvements in Toboggans; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention has reference to the fastening to the longitudinals of the toboggan crosspieces and side rails, and although specially adapted to the toboggan for which Letters Patent of Canada, No. 20,785, and United States, No. 312,879, have already been granted to me, may be applied to any of the ordinary kinds.

The device may be briefly described as consisting ofa light casting, comprising an eye, through which the side rail passes, and a seat set into the cross-bar and threaded to receive the screwed end of a bolt passed up through the longitudinal and cross-piece, and having its lower end, which is provided with ears or equivalent features, flush with the bottom of the longitudinals. The forward one of these eyes or fastenings has in it a slit, through which passes the end of the wire or cord from the turned up end of the toboggan. The rear one has a threaded opening on the top, in which works a set-screw,holding the side rod in place. By this means the side rod lies loosely in all the eyes, except the rear one, and is therefore enabled to follow the undulations of the longitudinals in passing over the ground, being at the same time securely fixed in place. Should either side rod become broken, it can, by my arrangement of fastening, be easily and readily detached and replaced.

For full comprehension of my invention, reference must be had to the annexed drawings, in which Figure 1 is a view of a part of a toboggan; Fig. 2, a longitudinal section through one of the castings in place on same; Figs. 3 and 4, details of front and rear fastenings.

Similar letters of reference indicate like parts.

A shows the longitudinal piece of the toboggan, B the cross-bar, and O the side rod, all these being of the usual arrangement, or, by preference, that covered by the patents above mentioned.

D is a casting, having an eye, d, through which the side rod passes, a neck and seat, d, set down on the cross-piece B, and a projec-v tion, d let into it. In this projection d and the neck d is formed a threaded aperture, d corresponding to the screwed end 6 of the bolt E, passing up through the longitudinal A and into the cross-bar B. This bolt,which is made with either ears or a head, E, is driven up through the longitudinal and cross-bar, and the casting D then screwed on its threaded end, the eyes being of course brought into line for the side rods, 0, to be passed through them. In the front eye is formed a slip, D, through which the wire or cord F is taken, and the rod then passed through the loop. The side rod is secured in its place by a setscrew, G, passing through a threaded opening in the rear casting, as shown in Fig. 4.

By the above-described construction and arrangement all the parts are securely fastened together, and at the same time to allow the longitudinals and side rods to follow the undulations of the surface over which they may travel.

What I claim is as follows:

1. A means for securing together the parts of a toboggan, consisting of a bolt passing up through the longitudinal and cross bar, and having a threaded end, on which is secured the neck of an eye, carrying the side rod, all substantially as herein set forth.

2. The combination, wit-h the wire or cord F, of the casting D, with slot D and side rod, 0, all as herein described.

Montreal, January 15,. A. I). 1886.
