Specification of Letters Patent.

Patented Apr... 13, 1915.

Application filed July 17, 1913. Serial No. 779,490.

To all whom it may concern Be it known that 1, Banner L. GAFLISOH, a citizen of the United States, residing at Clymer, in the county of Chautauqua and State of New York, have invented new and useful Improvements in Sleds, of which the following is a specification.

This invention relates to a sled which is more particularly designed for hauling logs in lumbering although the same may also be used for other purposes.

it is the object of this invention to produce a sled for this purpose which is very strong and durable in construction, which will. readily accommodate itself to any irregularity in the surface over which the same is drawn so as to relieve the various parts thereof from undue strain, and which can be produced at comparatively low cost.

in the accompanying drawings: Figure 1 is a perspective view, partly in section, of a sled embodying my improvements. Fig. 2 is a fragmentary vertical longitudinal section of the front part of the sled taken in line 22, Fig. 3. Fig. 3 is a vertical transverse section, taken in line 3.3, Fig. 2. Fig. l is a fragmentary vertical longitudinal section of the rear part of the sled taken in line et--i, Fig. 5. Fig. 5 is a fragmentary vertical transverse section taken in line 5-5, Fig. 4. Fig. 6 is a fragmentary vertical longitudinal section showing the manner of connecting the reach with the front bolster and beam, the section being taken in line 6-45, Fig. 7. Fig. 7 is a front elevation of the same.

Similar characters of reference indicate corresponding parts throughout the several views.

In its general organization my improved sled comprises two front runners 1, 1, two rear runners 2, 2, a front beam or cross piece t mounted on the front runners, a front bolster 5 pivotally mounted for horizontal rotation on the beam, a rear bolster or cross piece 6 connecting the ear runners, a longitudinal reach 7 connected with the front bolster and mounted on the rear bolster, a pole 8 pivotally connected with the front runners, and two pull rods 9 connecting the intermediate part of the reach with the rear runners.

Although the runners may be variously the construction which is shown in the drawings. Each of the runners as there shown comprises a knee 10 which. is constructed of a plank of wood arranged lengthwise and in an upright posiconstructed I prefer tion, a shoe 11 applied to the underside of r the knee and having an upwardly turned front end, and two cheeks or blocks 12 of wood secured to opposite sides of the knee adjacent to the upper edge thereof and about midway of its length. The upper edge of each of the knees may either be horizontal or straight throughout its length, as shown with reference to the rear runners in Figs. 1 and 4, or this upper edge of the knees may be turned upward slightly at the front ends thereof, as shown in Figs. 1 and 2, or the same may be of any other desired conformation.

On its upper part each runner is provided with a half-round bearing 13 which has its axis arranged horizontally and transversely of the runner and which is formed in the upper edges of the central part of the knee and the checks of the respective runner.

The front beam at is preferably constructed of a piece of wood which is rectangular in cross section and provided near its 0pposite end and on the underside thereof with half round journals 14 each of which is seated in and turns vertically in one of the half-round bearings of one of the front runners. Longitudinal movement of the front beam in the bearings of the front runners is prevented by means of shoulders 15 formed on the beam at opposite ends of the half-round journals and engaging with the outer sides of the cheeks thereof, as represented in Fig. 3. The front beam is connected with the front runners in such manner that these parts are free to turn one relatively to the other the means for this purpose shown in the drawings preferably comprising two pairs of upright tie coupling bolts 16 each pair having their lower parts passing through the cheeks of one runner while their upper parts are arranged in segmental slots 17 formed in the adjacent part of the beam journal, eyes 18 arranged at the upper ends of the tie bolts and axially in line with the axis of the beam journal and runner bearing, screw nuts 19 arbe easily assembled and and the beam. By; this 7 10 also preferably constructed of a lQOe of wood which is rec- 'tangularincrosssection and is provided lower near its opposite ends with two cylindrical journals-21 each of which is seated with its alf in the half-bearing of one of the rear runners. Each rear journal is confined .in-I the bearing of the respective runnerv by inea'ns'ofv a'pair of straps of iron each of which has a half-round central part 22 engaging with the upper side of the respect e cylindricalj urnal and fastening lugs 23 tll'lttllg'ed at opposite ends of the halfround part, of the strap and secured to the upper side of the adjacent check or bearing block of the runner by bolts 24', as shown in Figs. 1 and 4, or by any other suitable means At opposite ends of the cylindrical journals of the rear bolster the same is provided with shoulders 25 which engage with the-oute sides of the cheeks or bearing blocks andthereby prevent each of these runners and the rear bolster from beam, and 28 represents a similar a sents a' king bolt moving axially one relatively to the other. 7 Various means may be employed for connecting the front bolster and reach and pivotally connectingthese parts with the front beam. The means, however, which are shown in the drawings are suitable and preferred and constructed as follows: 26, 27 represent cooperating metal wearing plates secured respectively to the underside of the front bolster and the upper side of the front wearing plate of metal secured centrally to the underside of the front beam. 29 represents an upper coupling strap of metal secured of the and projecting forwardly through an openingf'30 in the central part of the front bolster, and 31 a lower metal coupling strap secured'to the underside of the reach at the front end thereof and projecting forwardly e upper side of the front end I thereof into a notch 32 formed centrally on the underside of the frontbolster. 33 reprepassing vertically through corresponding'openings inthe front bolster,

T j the front beam, the coupling straps and the wear plates, and. resting with its head 34 on toward the dogs on one side top of the front bolster. This king pin is held" against displacement by means of a cotter 35 passing through the lower end of the same and engaging with the lowermost wear plate, as shown in Figs. 6 and 7.

Upon drawing this sled over the ground each of its runners is free to turn vertically and adapt itself to the surface over which it passes independently of the other runners owing to the independent pivotal connection with each runner of its companion cross piece, beam or bolster, thereby preventing undue straining of the sled particularly when the same is heavily loaded with legs and not only permitting of hauling the load more readily over irregular ground but also saving the sled from undue wear and tear. Furthermore, this sled is so constructed that in the eventof any of its parts becoming broken by accident the same can be readily repaired.

When this sled is used for logging purposes exclusively the opposite ends of the bolsters are provided with. retaining dogs which are constructed in accordance with my invention. As shown in Figs. 1, 3 ftllll 2 63th of t-lltSt dog's COHIDIISGS a horizontal ase 36 secured to the upper side of the bolster at the, outer end thereof, an upright arm 37 projecting upwardly from the base, an inner pointed retaining spur 38 projecting upwardly from the arm along the inner side thereof and a laterally projecting pointed loading spur 39 arranged on the upper outer part of the arm.

Upon rolling the logs down, askid-way of the sled the outwardly projecting loading spurs 39 thereof engage the surface of the logs and prevent the same from turning so that the logs can be easily rolled from the skid-way by means of cant hooks over the respective dogs and onto the bolsters. After the logs have been loaded upon the bolsters the outermost logs of the load adjacent to the dogs engage with the upwardly pointing inner retaining spurs of the dogs, thereby pre venting the logs from, rolling off the bolsters.

By this construction of dogs the same materially facilitate the loading of the logs onto the sled and also retain the same upon the sled after being loaded, thereby enabling the logs tobe handled and transported in less time and with greater safety than has been possible with the means employed for this purpose heretofore.

I claim as my invention:

A sled comprising a runner having a knee, two cheeks or blocks secured to opposite sides of the knee and constructed to form a half-round bearing in the upper edges of said knee and cheeks, a cross piece having a rounded journal which turns in said hearing and means. for connecting said, runner and cross piece comprising two tie bolts ar- Witness my hand this 2nd day of July, ranged in said cheeks and in segmental slots 1913.

in cross piece and provided With eyes in line with the axis of said bearing and journal, and a pivot pin arranged in the eyes of Witnesses: both tie bolts and supported on said cross ORA B. CAFLIscH, piece. ELsm THOMPSON.
