Application filed October 26, 1911. Serial No. 656,868.

do deelarethe followin to be a full, clear,

and exact description o the invention, such as will enable others skilled in the art to' which it appertains to make and use the same. i y

This invention relates to mprovementsin sleds.

The main object of the invention-is to provide a sled having a combined one-piece cross beam and runner support which is very light, strong, and durable.A

Another object is to provide an improved construction of jointed runner, whereby a smooth surface engaging face is produced.

A further object is to provide improved swinging foot rests which will yswing automatically into inoperative position w en the sled is going up a hill.

Another object is to provide simple and efficient holding means for locking the jointed runners in rigid posit-ion.

lWith these and other objectsfin view the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawings: Figure 1 is a top plan view of a sled constructed in accordance with this invention, showing in dotted lines the manner in which the sled is steered; Fig. 2 is a bottom plan view thereof; Fig. Bis a central vertical longitudinal sectional View; Fig. a is a perspective View of the blank from which the combined runner support and cross beam is formed; Fig. 5 is a transverse vertical section taken on the line 5-5 of Fig. il; Fig. G is an enlarged horizontal sectional view of a portion of one of the runners, showing the construction of the improved joint; Fig. 7 is a side elevation of the joint; Fig. 8 is an enlarged detail sectional View showing the locking means for holding the runners rigidly conl tween said arms.

nected to the seat orv body portion of the sled; Fig. 9 is a detail perspective view of one of the stirrups. Fig. 10 is a detail side elevationy of a runner showing another form of joint; Fig. 11' is a bottom plan Viewv thereof. In the embodiment illustrated, a sled to or seat 1 is shown in the form of a series of Slat-s secured to the cross bars 2, the ends of which are fastened to longitudinal side bars 3 and the forward ends of these side bars are -riveted or otherwise secured to a front cross bar 4. r,

The cross bars or beams 2 are preferably constructed from a single piece'of sheet metal in the form shown in Figa, consist-` ing of a body portion 5 having diverging laterally extending arms 6 and 7 on its opposite sides near its opposite ends, and with extensions 8and 9 formed at the ends be- These extensions are olfset from the body portionl tovform members for engagement with the lower faces of the side bars 3, asis clearly shown in Fig. 2. The body portion of this beam has its side edges bent to form parallel substantially right angular flanges 10 and '11, whereby the beam is greatly strengthened. The arms 6 y .portion of the sled'are riveted to the body portion of these beams and this peculiar formation of the beams renders them light, strong, and durable' as Well as inexpensive'to manufacture.

The runners 12 are here shown as constructed of angle iron and are T-shaped in cross section, as shown in Fig. 5 with theirv lower faces rounded to form smooth surface engaging faces. These runners have one or 1 the front section with a curved recess 14 and the adjacent end of the rear section with a curved rounded projection 15. The webs or ribs of the runner sections are preferably connected by hinge members 16 and 17.se cured to the adjacent ends and pivotally connected by a pintle 18 which engages the lmuckles of the hinge members 16 and 17 and thereby hingedly connects the runner sections. By this connection, a smooth, fiat, unobstructed surface will be provided on the lower face thereof' to provide for the smooth running of the sled without jarring orjolting. In Figs. 10 and 11 a slightly different form of joint is shownin which the adjacent ends of the sections are p rovided with overlapping longitudinal eXtensions 12a and 12b the inner or upper face of the extension 12a on the front section' being beveled toward its, free end to form a knife v sion 12 on its lower or outer face.

edge which is rounded or curved on the arc of a circle to fit in a correspondingly curved recess 12c formed at the base of the exten- The outer face of this extension 12b is beveled toward its free end and laps under the eX- tension 12a as shown in Fig. 10. This close fitting joint forms a smooth unbroken surface and no foreignmatter can enter between the sections. The forward ends of these runners are curved upwardly in the usual manner and the free ends thereof are riveted or otherwise secured'to a cross bar 19 which has a laterally sliding engagement with the front cross bar 4 to which the side bars of the body or seat portion of the sled are attached.A This bar 19 is preferably notched, as shown at 20 to receive a. locking hook member 21 pivotally mounted on one of the side bars 3, the hooked end thereof being designed to pass through' a notch 4 in the front cross bar 4 and to engage the notch 20 in the cross bar .19 when the runner sections are arranged in a longitudinal alinement, and which thereby locks said sections rigidly together and prevents any lateral movement thereof relative to each other.

The central slat of the top or seat of the sled extends beyond the forward ends of the side slats and is pivotally connected to the inner end of a connecting bar.22, the outer end of which is pivotally connected tothe lower front cross bar 19. The end of said connecting bar 22 is voffset adjacent to its point of connection vwith the cross bar 19.-

A transversely arranged steering bar 23 is connected intermediately of its ends to the connecting bar 22 near the front end of the sled and the opposite ends "of said steering barproject over and beyond theside bars 3 of the sled. lThe steering bar 23 is braced by a short connecting bar 24 rigidly secured at its front end to the upper side of the steering barv and at its rear end is pivotally connected to the front end of the central slat of the sled seat. By thus rigidly connecting the steering bar 23 to the connecting bar 22 and pivotally connecting the latter to-the seat of the sled and to the cross bar of the jointed sections of the runners, it will be obvious that by pressing one end or the other of the steering bar. either by the hands or by the feet, that the front pivoted sections of the runners may be readily turned in either direction,'thereby steering the sled. f

The foot rests 25 and 26 arepivotally connected with the lower faces of the side bars 3 at any suitable or desired point thereon rand any desired number of-these rests may be used according to the number of persons the sled is designed .to carry. These foot rests are preferably constructed as shown in detail in Fig. 9 being formed of strips of metal pivotally connected to the side bars near one end with their other ends extending beyond the side bars of the sled and twisted to form foot receiving stirrups 27. The free connecting ends of these members are bent upwardly at right angles to form stops for engaging the inner faces of the side members 3 for limiting the movement of said rests when swung in opposite directions, the stirrups 27 being heavier than the inner ends ofthese rests, will swing inwardly and owing to their curvature the free ends thereof will extend under the side bars of the sled when the front end of the sled is turned upwardly in the position which it assumeswhen going up a hill, and thereby all danger of said stirrups engaging and tearing the clothes is avoided.

From the `foregoing description taken in connection with the accompanying drawings, the lconstruction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from'the principle or sacrificing any of the advantages of this invention as defined and claimed. y
