Specification of Letters Patent.

Application filed February 6, 1906- Serial No. 299,817-

Patented Sept. 18, 1906.

To all whom it may concern:

Be it known that I, PETER A. JOHNSON, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Folding Sleds; 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, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

This invention relates to improvements in sleighs' andsleds; and the main object is to provide a sled that may be folded together or knocked down and held in the folded posi tion during storage and transportation, the latter including not only transportation in shipment'of large numbers, but also where, for instance, a single sled is carried by a per son along any kind of pathway and then unfolded, loaded, and drawn with the load on it over a proper road to the destination of the load, this applying also where dogs or other draft-animals are used. This and other objects I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a top view, and Fig. 2 is a side elevation, of my folding or knockdown sled. Fig. 3 is a rear elevation of one corner of the sled. Fig. 4 is a bottom view of the crossbar 9 in Fig. 3. Fig. 5 is an end view of the cross bar uniting the front ends of the runners. Fig. 6 is a rear elevation of the cross-bar in Fig. 5 with a screw-rod added. Fig. 7 is a top view of the sled in its folded position with substantially all parts shown. Fig. 8 is a side elevation of Fig. 7 with the screw-hooks in heads of runners omitted. Fig. .9 is a bottom view of the main upper parts of the sled folded ready to be inverted and secured upon the runners, as in Fig. 8. Fig. 10 is a detail top view of one of the metallic plates or steps secured upon the runners for the support and fastening of the upper parts of the sled. Fig. 11 is a side or edge view of Fig. 10.

Referring to the drawings by referencenumerals, 1 1 are the two runners of the sled. These have in the folded position of the sled their front ends secured l screw-rod 2, having an eye 3 to turn it by and together by a short 4 at its end screw-threads engaging in a nut 4, secured in one of the runner-heads, while a washer 5, secured in the other runner-head, meets the ring 3, the rod passing through the two heads. When the sled is set up or unfolded, this short rod is carried in two eyebolts 6 6 upon the cross-bar 8 of the sled, the eyebolt 6 being screw-threaded to hold the threaded end of rod, while the runner-heads are secured together by a longer screw-rod 10, which bein inserted as shown in Figs. 1 and 2 holds t e mortises 11 of the heads firmly upon the tenons 12 of the head crossbar 7, the rod passing through the eyebolts or staples 13 of the bar. Said bar has a central hole 14 or other means to which a rope may be fastened for draft-animals hitched for drawing the sled.

Upon each runner are secured two metallic plates 15, formed with shallow pockets 16, which steady both sides and the rear of the lower ends of uprights 17. Said uprights have their upper ends formed with tenons 18, which when the sled is set up are inserted in mortises 19 in the cross frame- bars 8 and 9, and upon the latter are secured by pivots 20 the longitudinal bars 21, which have their pivotholes 22 slotted to allow the pivots to move toward the middle of the bar when the sled is folded, so that the framework will not be any longer than the runners when folded, as shown in Fig. 7.

The uprights 17 are braced in the upright position by the yoke-shaped rear braces 23, joined at 24, one upon the rear side of each post and having the lower end pivotally engaging at 25 the plate 15. They are further braced by being pivotally connected in pairs or as many uprights as there are on one runner by a horizontal brace 26 and by the brace-yoke 27, extending therefrom, being pivoted at 28 and engaging the screw-hook 28*, sliding in the head of the runner and having a thumbnut 29 forcing it forward and a tight nut 30 to prevent the thumb-nut from getting lost. Against transverse folding the uprights are braced by beinginserted in the bars 8 and 9 and by having each anoblique brace 31, (best shown in Fig. 3,) pivoted at 32 to the crossbar and having a hole 33, going upon a staple 34, secured in the upright, and a pivoted hook 35, carried by the brace .and engaging the staple, so as to keep the brace on it. When the sled is folded, said braces are placed with their apertures 33 upon revoluble eyebolts 36 (see Fi 8) and retained there by turning the eyeboi with its eye out of line with or across the aperture in the brace.

While the braces are thus held their hooks are hooked into sta les 37 in the runners, and thus hold the fol ed uppe'rparts of the sled secured upon the runners, as shown in Fig. 8, the parts being first folded, as in Fig. 9, where it will also be seen that a special brace-hook 38 is pivoted at 20 and engages a in to help hold the parts. together in fo ded position. When said hook is not in use, it is held secured below the bar 9 by engaging the pin 41 in said bar, as shown in In the folded position of the sled the rod 10 and bar 7 occupy the position shown in Fig. 9, the rod being screwed into the same staple or eyebolt 6 that receives the end of the short i T placing first up rod in Fig. 1.

The rear ends of the runners are held together by a double hook 42, pivoted upon one runner and engaging with one of its hooks the pin 43 in the other runner, and when the sled is set up the hook is held steady in its idle position by having its other hook firmly engaged with a in 44, fixed in the runner carrying the hoo Near the ends of the cross-bars 8 and 9 I provide holes 46, serving as stick-pockets for insertion of suitable sticks (not shown) to helIp hold a bulky load on the sled.

n the present instance the braces 23 have their lower ends pivoted to the runners by being passed into the groove 25 in the under side of the plate 15, and the pockets 16 are open at their front side, as the uprights are firmly braced against motion forward with the lower ends; but it is obvious that such and many other details maybe modified without diverging from the scope and spirit of my invention.

In using the sled the load is placed upon the bars 21, either directly or indirectly, by

on the bars supporting means suitable for the articles to be auled.

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

1. A sled comprising a pair of detachablyconnected runners, a detachable bar between the heads of the runners, a long screw-rod passed through the heads and adapted to draw the heads together against the ends of the bar, and a shorter screw-rod to take the place of the long one and hold the heads close together when the bar is removed, and a hook securing the rear ends of the runners together when the sled is folded, and means for holding the idle rod when the other rod is in use,

substantially as set forth.
