SLED.

Specification of Letters Patent.

Patented Apr. 4:, 1922.

Application filed May 15, 1919. Serial 30. 297,293.

To all whom it may concern:

Be it known that ADAM: ROLEY, a citizen of the United States, residing at Basil. in the county of Fairfield and State of'Ohio, has invented certain new and useful Improvements in Sleds, of which the following is a specification.

This invention relates to improvements in sleds, and has particular reference to that class of sleds commonly termed bob sleds.

The object of the invention is to provide a sled of this character which shall be simple in construction yet characterized by its general strength and durability. e

Another object resides in a sled of the aforesaid description wherein improved means have been provided for bracing and supporting the runners thereof, so that the latter will be capable of receiving the many complex stresses imparted thereto without liability of becoming broken or out of order.

A further object of the invention rests in the manner of connecting the tongue structure of the sled to the bolster frame, in order that saidtongue will be permitted to oscillate in desired directions without binding or engaging adjacent stationary parts. and to construct the connecting elements of said tongue in an efiicient and thoroughly braced manner to prevent disorder between the working parts thereof.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the novel features of construction, combination of elements and arrangement of parts, hereinat'ter to be fully described and to have the scope thereof pointed out in the appended claims.

In the accompanying drawing forming a part of the specification, and in which similar characters of reference denote like and corresponding. parts,

Figure 1 is a top plan view of the improved bob sled comprising the present invention,

Figure 2 is a vertical longitudinal sectional View taken along the line 2-2 of Figure 1,

Figure 3 is a front elevation of the forward portion of the sled,

Figure 4 is a transverse vertical section taken along the plane disclosed by the line 44 of Figure 2, and

mounting of the latter.

Referring more particularly to the .fea-. tures of the invention, as they have been exemplified in the accompanying drawing the numeral 1 designates the improved bob sled in its entirety. This sled is formed to comprise a forwardly situated set of transversely spaced parallel runners 2, and a similar set of rearwardly situated runners 3. Located above the runners 2 is a transversely extending front bolster 4,. beneath which is pivot-ally mounted a'parallel beam 5. a king bolt 6 being disposed to centrally pass through aligning openings formed in both the bolster and beam toefiect the pivotal Ametallic wear plate 7 is secured, in this instance. to the underface of the bolster 4c in order to receive such wear as is incident to the turning of the elements about the king bolt 6. Also secured to the plate 7 is a forward end of a reach member 8, which latter being disposed to extend longitudinally of the sled 1 and has its rear end suitably connected with a rear bolster 9, to which the runners 3 are connected. Load sustaining standards 10 project vertically upward fromboth of said bolsters and serve to retain the matter carried by the sled against displacement. or if desired a suitable body structure, not shown, may be supported by these standards.

In order to securely unite the runners 2 with the beam 5 the latter is provided with depending spaced blocks 11 through which pairs of vertically disposed bolts '12 are adapted to pass so that the blocks may be firmly secured to the underface of the beam.

These bolts 12 are also arranged to pass bolts, so that/the beam 5, its blocks 11 and the members 18 may be securely united in a rigidly assembled condition. The vertical sides of the members 13 are arranged to engage with the inner sides of the runners 2 and securing devices '15, in this instance bolts, are disposed to passthrough said runners and through the co-operating portions of said angle members in order that the runners may be substantially connected with the beam structure 5. By virtue of this construction, means have been providedfor effecting a homogeneous union between the runners 2 and the associated beam structure so that the various lateralstresses to which the runners willbe placed will be amply provided for and undue fracture between parts precluded. However, in order to strengthen the outer portions of the runners 2, and to relieve the angle members 13 of the burden of absorbing the runner stresses, the invention contemplates the provision of angularly' disposed truss members 16. These members" have their outer ends secured as at 17 to the adjacent ends of the runners 2. The inner ends of said rods extend or terminate contiguous to the central portion of the beam 5, and bolts 18 are employed to pass through the meeting extremities of these truss members and to ri idly unite the same to said beam. Throug this mannerof connecting the .front runners to the beam an. exceptionally strong and substantial construction is provided, in view of the fact that said runners will be fully braced against lateral pressures.

Carried by the lower end of the king bolt 6 and confined between its securing nut 19 and the underfaoe of the beam 5 is a clevis '20, and a similar cooperating clevis 21 is secured to the inner end of-a tongue structime 22, a link 23 being utilized in this instance to pass through the eyes formed in said clevises so that the tongue structure will be permitted to oscillate vertically, in order that the same will assume positions best adapted for draft purposes; A bolt-24 may be employed to connect the clevis 21 with the tongue 22. The inner end of the tongue 22 is adapted preferably to lie on a plane substantially below the front bolster 4, so that the pivoting of the front runners will take place about a relatively extended are without binding occurring between the end of the tongue and adjacent portions of the bolster 4. This constructionis particularly desirable in the execution of relatively sharp turns. To brace the tongue structure against lateral stresses and to enable the y draft power; to be directly applied to the runners2 withoutpassing through the clevises which have their forward ends secured to the tongue by means of a transverse bolt 26, and gthe rear ends of these braces 25 are connected withdiniksilf, whichare rigidly carried by thebeam 5, said links being preferably isecuredto the beam 5 by means of the- bolts 1,2,50 that the latter'may beusefully emi played in the dual capacity of unitingthe a rear runnersBare connected with the l-pfiwiimately the same manner lfidd connecting the front -mn- 2 and 21, use is made of a pair of braces 25, 7

ter members functioning, as the members 16 to substantially brace the runners 3 and to securely unite the same in unison with the bolster 9.' A vertically disposed bolt 32 passes centrallythrough the bolster 9 and through the adjacent portion of the reach member 8, therebyserving to secure saidboL aster and its associated parts in connection with the reach member. This relationship between said bolster and the reach member may be of an ad usta-ble nature at desired.

To relieve the bolt 32 of draftstnainansc is made of a pair oflinks 33, which have their lorwardends connected with a bolt '34- carried, by the reach member, the rear ends of the'links 33 being disposed to en sift? with eyes 35-rigidly carriedby 9. Said eyes are preferably retained iniprrsition bymeansof the bolts 30 which are employedto unite the block 2831111 theianglae members 29 to the. undeiside of the bolster 9. The links 33 further function to prevent oscillation or pivotal movement of the bolster 9 about the rear end Off the member 8, inorder that the rear runners will vfollowithe general course of movement of the sled as a whole. V r a From the foregoing description, takenv in connectionwith the accompanying drawing, it will be apparent that thereds rovided a sled of the character stated whine possesses exceptional strength and improved features of construction which insure the longilife of the sled. Through the manner described for connoctingthe runners of the sled with their associated frames the possibility of the runners collapsing or buckling under the influence of lateral stresses is avoided and in this mannergone ofthecommon weaka nesses, hitherto found in sleds of this class eliminated. In view of the foregoingiit is thought that the operation, construction and advantages of the invention will beaelaearly perceived by those versed thezaa't, and

therefore a more extended explanationhas sheen accordingly omitted. u 'What Iclaim is:

i. In a bob-sled, a bolster, crossbar posed; beneath said bolster, a pivotal cornicetion intermediatelyrof. the length ctr ss-id cross-bar for connecting the latter with "said bolster, blocks fixed to the Iunder-smdouter portions of said cross bar, angle brackets having their horizontal'legs seoured to' said -3 blocks, a pair of spaoedmamllel and .ver-

tic-ally arranged runners secured to the vertical legs of said brackets, and rigid outwardly diverging brace rods having their inner ends connected with said cross bar and their outer ends connected with said runners at points spaced from said angle brackets.

2. In a bob sled, a cross bar, blocks fixed to the under and outer portions of said cross bar, angle brackets having their horizontal legs secured to said blocks, a pair of spaced parallel and vertically arranged runners se-.
