SLED.

Specification of Letters Patent.

Patented Dec. 1, 1914.

' Application filed March 12, 1914. Serial No. 824,312.

To all whom it may concern:

Be it known that I, FRANK R. PEETS, a citizen of the United States of America, and a resident of Merrill, in the county of Clinton and State of New York, have invented a certain new and useful Sled, of which they following is a specification, the same being 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.

My invention relates to vehicles mounted on runners for the conveyance of loads over frozen snow or ice, and particularly to the class of such conveyances commonly designated as loose-jointed sleds, or bob-sleds, and it consists in certain novel features of construction and arrangement of parts and in the combination of the same for efficient service, whereby among other useful results a variable carrying capacity of the vehicle according to different widths of loads and the accommodation of the runners to different widths of roads may be secured, while providing strength, durability and simplicity of the working parts.

In order to enable the invention to be fully understood I shallproceed to explain the same by reference to the drawings, illustrative of one embodiment of the invention, which accompany and form a part of this specification, in which- Figure 1 represents a side elevation of a device constructed according to my invention, Fig. 2 is a plan view of the same, and Fig. 3 is a view in detail of the tongue or draw bar.

Like letters of reference indicate like parts in all the views.

Referring particularly to the drawings, A denotes the runners of my device, preferably used as a double sled, which runners ordinarily have their forward ends upwardly bent or curved, as is usual. These runners may be made of any suitable or approved material, but I prefer to construct them of wood faced with metal armor, as the side plates a and top and bottom plates a The forward portions of the runners and also the rising parts or knees, as (1, thereof, are preferably connected together in a distensible relation by cross beams and bolts as D, D which may be lengthened or shortened at will.

I prefer to make the element D of metal tubing the opposite ends whereof are interiorly threaded. Into the said threaded extremities are ordinarily placed screws or bolts, as D, which bolts pass through the runners, the heads thereof lying on the exterior side faces of the runners, and the said runners may be securely held at any desired distance apart, as by nuts cl, which work on the bolts and are preferably screwed up against the inner side faces of the sled runners, although, if desired, the cross beams may have some movement in the said runners. Any number of cross beams and bolts, as D, D, may be employed according to the length of the sled and the particular requirement of the use of the same.

Inasmuch as my invention is adapted for use in conveying heavy loads of logs or other material over rough and uneven roads, I provide means to secure a straight draft between the front sled and that, or those, in the rear thereof, or uniform movement of the same in turning corners, and also to secure lateral and longitudinal adjustments thereof, the whole being con structed in such a manner as will permit the heavy load to be safely conve d without injury to the conveyance en any portion thereof is subjected to sudden strains as when passing over uneven portions of the road bed. With this object in view I mount a bolster E over the knees a, the same being preferably made of wood and secured by connections G to the therebelow positioned beam D, (sustained by the bolts D) and held in such a manner as to have, if so desired, a somewhat rocking movement. In some cases. however, it is desirable to have the bolster E rigidly attached to the cross beam D. The upper and lower surfaces of the bolster E are preferably provided with a metal facing, as e, particularly at the central portion of the same.

According to my preferred arrangement I secure a sand bolster, as E, e, to the bolster E in a pivoted relation as by means of a ring F having a depending headed shank f and attached to the said bolster in such a manner as to have a swivel or rotary movement. The distensible sand bolsters, like the cross beams D. D, are preferably made of metal tubing E in which work screws or bolts 6, the outer ends of which latter parts serving to securely support sway bars, as H. In case a plurality of sleds are used the same are preferably connected together by cross chains as B, which, as Well as the sway bars H, may be shortened or lengthened at will, according to the size and character of the load to be carried which may be held on.

the sled by binding chains, as C.

By the use of my invention a wide load may be securely held on the sledand trans--' ported over a narrow road bed, or a narrow load may be safely conveyed if in case for some reason, it was desired to have the runners spaced farther apart asi'for ex ample to accommodate the same to a Wide roadway, whileby means ofthe construc-' tion shown and described, the runners, though straight, may adapt themselves to a curve in the road and'thereby minimize the strain on thesled, the bolsters in the mean time accommodating themselves to the movement of the runners, whereby the braced, although it may be held in a some.

what laterally movable relation, as by a spreader orstay' .iro'n j", and it may also, be secured to the cross'beam;-as by a clamping iron=or clevis J. The evener I is also preferably constructed in a similar manner and is prqferably applied to a cross bar D as by. means of a loosely attached connectiona.

In addition to the features of construction. embodied in the distensible beams; Which af- I ford a strong or rigidfas well as variable structure, it is evident that it is impossible for any of the parts of the sled to become accidentally displaced by reason of unusual strains and also repeated jars occasioned by the-conveyance passing over mountain roads "of different faces, while the sled runners and knees beinginclinations and uneven surformed integral with each other are very strong and durable. The movement of the bolsters and sand bolsters as well as that of the sway bars, afiorded by'the construction described and shown causes a minimum strain to be exerted upon the different parts of the 'sled' as the said parts accommodate themselves to the movementof the runners.

I wish it to be understood that 'I do not" desire to limit myself to the exact details of construction shown and described, for

obvious modifications will occur to a person skilled in the art.

hat I claim as my invention 'is 1. In a device of the class described, a

pair of runners, a distensible cross beam to adjustably hold the runners apart anydesired distance, and a distensible sand bolster and means to hold the same so as to have a. rotary movement.

2. In a. device of the class described, a pair of runners, a distensible cross beam. to

adjustably hold the runners apart any desired distance, and a distensiblecsand bolster and means to hold. the same 'so as to have a rotary movement, in combination with'a similar sled and with sway bars to connect" the ends of the sand bolsters together:

In testimony of the foregoing specifica-' tion, I do hereby sign the same in Ellenburg, county of Clinton and State of New York, this second daylofFebruary 1914. FRANK R. "PEETS \Vitnesses 1 CHAS. 11V. BAoKUs, LYMAN COLLINS.
