BOBSLED.

To all whom it may concern:

Be it known that I citizen of the United %tates,

Merrill, in the county O'r'ro ll. NinNow, a residing at of Lincoln and State of \Visconsin, have invented certain new and useful Improvements in Bobsleds; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and'use the same.

This invention rela tee to sleds, and especially the form of sled known as a bobsled One object of this invention is to provide an improved sled which is exceedingly strong, rigidand durable and can be manufactured at a comparatively low cost.

Another object is to knockdown sled which easily be assembled by son of even less than provide an improved can very quickly and a child or other perordinary ability.

Other objects and advantages may be apparent to persons who read the followmg details of description i n connection with the accompanying drawings in which:

Fig. 1 is a side elevation of my improved bobsled, the handle or tongue having a portion broken out and being turned backward. Fig. 2 is a top plan view of the bobsled, the tongue being broken off.

3 is a transverse vertical sectional view along the lines 3 Fig. 4 18 a 3 of Figs. 1 and 2.

transverse vertical sectional view along the lines H of Figs. 1 and 2.

Fig. 5 is an enlarged detailed view, partly in side elevation and partly in section, of one of the sled-runners.

Fig. 6 is a longitudinal sectional detail,

the section being taken Fig. 2.

along the line 6-6 of Fig. 7 is a horizontal sectional detail, the

section being taken along the line 7-7 of Fig. l.

Referring to these drawings in detail, in which similar reference characters correspond with similar parts throughout the several views The device comprises two pairs of runners 1 and 2 which are somewhat similar though not identical in construction. A rear cross beam 3 connects the runners of the rear pair 1, and a front cross runners of the front beam l connects the pair. Moreover, the

front ends of the rear pair of runners are connected by means of is pivotally connected a strut or bar 5 which to these runners by Serial No. 536,253.

means of pins 6 retained in place by cotter keys 6, this bar 5 being an element of a link or coupling device which is loosely connected with the front cross beam at by a hook 7 which fits into an opening 4 formed in the front cross beam l. Similarly, the front ends of the front runners 2 are connected by means of a strut or bar 8 which forms an element of the tongue member which has a handle 9 on its free end, this bar 8 being also pivotally connected by means of pins 6.

All the main parts described in the foregoing are preferably made of malleable cast iron and are all of llbeam construction, that is, the runners, for instance, are each formed with a web 10 and a marginal flange 11, this flange extending outward in opposite directions from the faces of the web 10, as clearly illustrated in Figs. 3 and ft. The bottom portion. of the flange 11 is apertured, as indicated at 12 in 5, to receive securing bolts 13 which extend therethrough from a runner-shoe 14. The inner ends of these bolts 13 extend into apertures 15 which are formed in the web 10, and nuts 16 engage with these bolts 13 for securing the runner-shoe on the runner beam. The ends of therunner-shoe may be interlocked with the flange 11 as indicated at 17 in Fig. 5.

Each runner is formed with uprights l8, and each of these uprights is formed with vertically extending ribs 19, a space or slot 20 being provided between the ribs 19 for receiving a narrow web 21 of the rear beam 3, or a somewhat similar web 22 of the front beam l. The only substantial difference be tween the rear and front runners is that the ribs 19 of the latter are longer than those of the front beam. However, this difierence in the lengths of the ribs is not essential and the front and rear runners may be identical in construction. The upper portion of the flange 11 includes a U-shaped saddle which is indicated at 23 in Figs. 3, a and 5, and this saddle of each runner receives and embraces a downward extension 3"of the rear cross-beam 3, each of the webs 21 being included in these downward extensions. However, the webs 21 fit within the slots 20, and this arrangement of the cross beams and their respective pair of runners prevents lateral and angular movements of the parts thus fitted together. The rear cross beam is provided with recesses 2% which extend therethrough above the webs 21, and securing bars are seated in the recesses 24 and have their ends secured to apertured lugs 26 of the runners by means ofbolts 27 havlng nuts thereon. The front runners are provided With securing bars 25 and bolts 27, the latter extending through apertured lugs 26, these elements being substantially the same as described for the rear runners; but

instead of front cross beam 2 being formed With an aperture therethrough to receive the securing bar 25, this bar extends acrossthe ends of the cross beam and is secured by the bolts 27. that the front cross beam is lower than the 7 rear cross beam, and-that a bolster 29 is se- In this connection it will be-noted cured thereon by means of a pin or bolt 80 which extends through the bolster and through the cross beam 4 and also through an eye in the hook 7 to loosely connect the hook with the cross beam.

By the construction previously described, of the means of joining the crossbeams to the runner beams, these members are yery strongly and rigidly united, and they may be very quickly disunited by simply removing the bolts 27, detaching the bars 25 and" then lifting the crossbeazns from the saddles of the runners. P i

What I claim as my invention is: In a sled, runners each formed of a single casting and having a Web portion provided with upstanding arms intermediateits length and a marginal flange extending transversely of therunner beyond itsinner and outer side faces, the portion of the flange extending beneath the runner being reduced intermediate thelength of the runner to prov de a seat, a ground-engaging strip secured in said seat, ribs extending ing across the end portions of the cross bar to prevent upward movement of the cross bar.

In testimony whereofl have hereunto set yor'ro J. IE OW;

my hand.
