FREDERICK IV. ZURBURG, OF CHICAGO, ILLINOIS. i

SPECIFICATION forming part of Letters Patent No. 231,746, dated August 31, 1880,

i Application filed July 16, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. ZUR- BURG, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Sleds, of which the following is a specification.

The object I have in view is to produce a simple and cheap childs sled, which can be readily taken apart or knocked down, so that it `can be packed in a small space for storage or transportation, and will therefore be much cheaper to handle than the sleds now made, can be easily put together withoutother tools than a wrench, and will be exceedingly strong in construction. i

My invention consists in the several novel features embodied in my improved sled, as fully hereinafter explained, and pointed out by the claims.

In the accompanying drawings, forming a part hereof, Figure 1 is a perspective view of the sled; Fig. 2, a vertical crosssection of the same through the center of the forward crossbar, looking toward the tail of the sled; and Fig. 3, a vertical section from front to rear through the left-hand-side forward joint, looking inwardly.

A represents the runners, B the standards, C the cross-bars, and I) the board, of the sled.

The runners are bent from wood, and are of' the usual construction. The standardsB are of cast metal, and are made of any suitable design. Each standard at its bottom terminates in a plate, a, which is the width ot'therunner, and rests thereon. Lugs I) project downwardly from the sides of the plate a, and inclose between them the runner, the standard being secured to the runner by wood-screws c pass ing through said lugs, or by a rivet or a bolt. The plate and lugs form a very stift' joint between the run ner and the standard.

Near its upper end each standard has an inwardly-projecting lug, d, with outwardly-bev: eled side edges, which lug slides, like a stoveleg fastening, in a dovetail way, e, formed in a cast-metal plate, E. One of such plates is secured to each end of each cross-bar by a wood-screw, f.

The extensions of the standards above the lugs d abut solidly against lthe ends of the cross-bars.

At the ends of the rear cross-bar bolts (not shown) pass downwardly through the crossbar, the plates E, and lugs d, and have nuts on their lower ends, by tightening which the parts are drawn lirmly together.

The runners are bent upward and rearward at the front ends. and rest on the ends of the forward crossbar.

Bolts t pass down through the ends ot' the runners, through the forward cross bar, the plates E, and lugs d, and are secured by nuts la on their lower ends. These` bolts are like those that pass through the rear cross-bar, eX- cept th at the latter only pass through the crossbar, plates E, and lugs d.,

The cross-bars are of wood, and the board is secured to them by wood-screws.

A front round, Z, is held between the curved front ends of the runners by means of holes or sockets bored through or in the runners, and without other fastenings.

Now, it will be seen that by removing the four bolts the sled can be taken apart and packed in about one-fourth of the space it occupies when set up. The sled can also be easily put together, and is strong and durable.

What I claim as my invention isl. In a knockdown sled, the combination of the metal standards B, having dovetail lugs d, the metal plates E, secured to the crossbars, and having dovetail ways or grooves e, and the bolts passing through the cross-bars and through said plates and lugs, substantially as describedV and shown.

2. In a knockdown sled, the standards having lugs projecting under the ends of the cross-bars, in combination with the runners bent back upon the forward cross*barand the bolts t' passing through the ends of the runners and securing the forward cross-bar and standards together, substantiallyas described and shownf` 3. A knockdown sled wherein the standi .ards have laterally-projecting lugs or wings extending under the ends of the cross-bars, and the runners are bent backward upon the ends of the forward cross-bar, 1n combination with four bolts that secure the parts removziards, and runners being held together at the bly together, substantially as described und top of the sled by four bolts, substantially es ro shown. set forth and shown.

4. The knockdown sled described, consist- FREDERICK W. ZURBURG' 5 ing of runners A, standards B, cross-bar C,
