SPECIFICATION forming part of Letters Patent No. 783,437, elated. February 28, 1905.

Application filed February 5, 1903. Serial No. 142,081.

This invention relates to bob-sleighs, and` has for its object to provide an improved construction of knee, so as to obtain a tiltable or rocking connection between the knee and the knee beam or bolster to permit tilting movements of the runner when encountering irregularities in the roadway, and thereby to avoid strain upon the body of the sleigh. It is also proposed to brace the joint between the knee and the bolster from the forwardl upturned portion of the runner and to have the brace constitute a part of the joint, so as to materially simplify the connection between the brace, the knee, andthe bolster and at the same time to preserve the strength and durability thereof. f j

W ith these and other objects in View the present invention consists in the combination and arrangement of parts,as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit l or sacrilicing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a side elevation of a bob-sleigh embodying the features of the present invention. Fig. 2 is a fragmentary top plan view thereof. Fig. 3

4is a rear elevation of the sleigh. Fig. 4 is a which rest fiat upon the top of the runner and are bolted or otherwise secured thereto by means of suitable fastenings 7. The upper ends of the standard portions or sides 3 and 4 of the knee are connected by a suitable horizontal cross-bar 8, which is provided at its middle with a depression or socket 9. A substantiall y horizontal brace-bar 10 has its front upturned end connected to the rear side of the upwardly-bowed portion 2 of the runner, as indicated at 11, with its rear extremity flattened, as at 12, so as to lie flat upon the top of the cross-bar 8, and is provided intermediate of its ends with an upwardly-bowed portion 13, constituting a socket registering with the socket 9 and producing a substantially circular bearing, there being bolts 14 or other fastenings piercing the cross-bar 8 and the flattened rear end of the brace 10, so as to rigidly connect these parts'.

Upon corresponding knees, as clearly indicated in Fig. 3 of the drawings, a knee beam or bolster 15 is supported and is connected at each end to the adjacent knee in the following manner: A metallic plate 16 is secured to the under side of the bolster' by means of bolts or suitable fastenings 17, and adjacent the inner end of the plate there is a pair of spaced pendent ears 18, pierced by corresponding perforations, there being a similar pair of pendent ears 19 adjacent the opposite end of the plate, the ears 19 embracing the bearing formed by the parts 9 and 13 of the cross-bar 8 of the knee and the rear flattened portion 12 of the brace 10. A substantially V-shaped brace member 20 has the extremities of its sides secured to the inner faces of the sides 3 and 4 of the knee about midway of the lengths thereof, as indicated at 21, from which the brace inclines upwardly and inwardly and terminates at its upper end in an eye 22, which is received between the ears 18, there being a coupling bolt or bar 23passed through the ears 18 and 19, the eye 2.2, and the bearing upon the top of the knee, suitable'nuts 24 being provided upon the ends of the coupling bolt or bar to hold the same against end wise displacement.

It will here be explained that the couplingbolt 23 fits with suiiicientlooseness within two pairs of ears, the eye 22, andthe bearing upon the top of the knee to permit of the runner rocking or tilting upon the coupling-bar 23 as a pivotal support, thereby to accommodate the runner to irregularities in the road way without materially affecting the body of the sleigh. Moreover', as the nuts 24 engage the respective adjacent fixed ears 18 and 19 the tightening of the nuts does not cause a binding of any of the parts of the pivotal joint, which is a very im portant advantage, as otherwise the joint would be rendered stiic and ineffectual for the purpose designed.

The simplicity of the joint between the knee and the bolster is apparent, and it will also be noted that when the bolt or bar 23 is removed, so as to permit separation of the runner from the body of the sleigh, the brace l0 remains connected to the knee, 'and therefore the bearing at the top of the knee is unaffected and remains in condition to be rengaged with the coupling-bolt 23 at any future time without requiring an assemblage of the brace l() and the knee. Furthermore, as the brace 10 constitutes a part of the bearing the bracing effect is applied directly at the bearing instead of at one side thereof. whereby the most effective bracing of the bearing is obtained and there can be no twisting of said bearing.

Having fully described the invention, what is claimed is l. The combination of a runner having an upturned front end, a knee rising therefrom and including upstanding sides and a crossbar connecting the sides and provided intermediate of its ends with a half-bearing,a brace connected to the upturned front end of the runner with a portion secured to the top of the cross-bar of the knee and provided with a half-bearing registering with the half-bearing of the knee, a bolster having a pair of pendent bearing-ears lying at opposite sides of the registering' half-bearings of the knee and the brace-bar, and a coupling member piercing the bearing-ears and the bearing to permit tilting movements of the runner upon the bolster.

2. The combination of a runner having an upturned front end, a knee rising from the runner and including upstanding sides and a cross-bar connecting the upper ends of the sides, the cross-bar being depressed intermediate of its ends to form a half-bearing, a brace connected to the upturned end of the runner with a portion lying upon the top of the crossbar and provided with a raised portion constituting a half-bearing registering with the half-bearing of the cross-bar, fastenings connecting the cross-bar and the brace at opposite sides of the bearing, a bolster having a pair of pendent ears lying at opposite sides of the bearing, and a coupling-bar piercing the ears and the bearing.

3. The combination of a runner having an upturned forward end, a knee rising therefrom and including upstanding sides andA a cross-bar connecting the upper ends thereof, the cross-bar being provided with an intermediate depression forming a half-bearing, a brace connected to the upturned end of the runner with a portion lying upon the top of the cross-bar and provided with araised part constituting a half-bearing registering with the half-bearing of the cross-bar, fastenings connecting the brace to the cross-bar at opposite sides of the bearing, a bolster, inner and outer pairs of pendent bearing-ears carried by the bolster, the outer pair of ears embracing the bearing upon the top of the knee, a substantially V-shaped brace having its ends secured to the sides of the knee and inclined upwardly and inwardly therefrom with its upper portion provided with an eye located between the inner ears, and a coupling-bar piercing the ears, the eye, and the bearing upon the knee.

ln testimony that we claim the foregoing as our own we have hereto affixed oui signatures in the presence of two witnesses.
