BOB OR COASTING SLED.

Specification of Letters Patent.

Patented Aug. 15, 1916..

To all whom it may concern:

Be it known that I, CLAYTON D. HIME- BAUGH, a citizen of the United States, residing at Burr Oak, county of St. Joseph, and

5 State of Michigan, have invented certain new and useful Improvements in Bob or Coasting Sleds, of which the following is a specification.

This invention relates to an improved bob or coasting sled.

The main objects of this invention are: First to provide in an improved bob sled, an efficient and adjustable tension means for facilitating the steering of the same. Sec- 0nd, to provide in an improved bob sled, an adjustable tension means whereby the front sled will be returned to its normal position after any turning effort has been removed from the same.

o Further objects, and objects relating to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of my invention 5 by the devices and means described in the following specification.

The invention is illustrated in the accompanying drawings forming a part of this specification, in which:

o Figure I is a side elevation of my im proved bob or coasting sled embodying thefeatures of my invention. Fig. 11 is an inverted plan view of the said bob or coasting sled. Fig. III is an enlarged partial detail 5 horizontal section showing the operation and connection, ofjthe' front sled tension means taken on line 33 of Figs. 1, IV and V. Fig. TV is an enlarged partial detail vertical section showing the connection of 0 front sled to the spring tension means, taken on line 1t of Figs. 11 and V. Fig. V is an enlarged partial detail vertical section through the front sled king bolt, taken on line 55 of Figs. 1, II and IV.

5 In the drawings similar reference characters refer to similar parts throughout the several views, and "the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

0 Referring to the drawings, the bob sled top 1 consists of boards held together by the front bolster 2 and rear beam 3 respectively. The rear sled consists of the runners 4 which are connected to beam 3 by the 5 knees 5 fastened at their forward ends to the top 1. The front sled consists of runners 6 fastened at the front end by steering cross arm 7, the knees 8 of which are securely connected to beam 9 of channel iron. A rave-like brace 10 connects the nose of each runner to the beam 9. The beam 9 is adapted to turn and bear'against the bolster 2, said bolster 2 having on its under side the metal bearing plate 11 which forms the bearing surface for the beam 9. The front sled steering or king bolt 12 is adapted to pass through the bolster 2 and the beam 9 thus permitting the front sledto turn for steering. In the bolster 2 and next to plate 11 is a notch adapted to engage one of the spring yoke halves 13. This yoke half has a slot 1 1 through which passes the bolt 12. On the under side of the cross piece 9 is also disposed the lower yoke half 15 with a similar slot in it through which the bolt 12 passes. In front of beam9 and pivoted on pin 17 between the forward ends of the yoke halves l3 and 15 is the rock bar 16. Connecting the rear ends of the two yoke halves is the tension spring 18 Spring 18 is hooked at its rear end to the eye bolt 19. Eye bolt 19 passes through a guard piece 20 and has at its rear end the wing nut 21. Variabletension is thus put on the spring when wing nut is turned. The front end of the guard piece 20 is fastened beneath the lower yoke half 15 by the king bolt nut 12, as shown, the rear end of said guard 20 being fastened to the sled top 1. Around king bolt 12 and within the channeled portion of beam 9 is the compression spring 22 serving to keep the adjacent parts in a yielding relation to' each other. The slot in yoke half 15 is somewhat wider than that of yoke half 13 to permit spring 21 to pass through thus giving the same degree of movement to each. Therefore, when the front sled is turned, as shown in Fig. III, one end of rock bar 16 will bear against that half of the front sled beam 9 which swings forward about the king pin 12. The other end of the rock bar 16 will fulcrum on bolster 2 and the resultant forward movement of pin v tion. Also when the front sled is turned to make a curve, the spring causes a steady pull on the steering arm which is advantageous for careful steering. I have thus produced a tension means and centering means by the action of a single spring.

I have illustrated and described my improved sled in detail in the form in which I have embodied the same for the market. I have not attempted to illustrate or describe possible modifications and variations in structural details, which I contemplate, as I believe the disclosure made will enable those skilled in the art to which my invention relates, to embody my improvements 'as conditions may require. I desire, however, to be understood as claimlng my improvements specifically in the form-illustrated, as well as broadly, as appears in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. Ina bob sled, the combination of the top, a rear bob secured thereto, a bolster at the front, a front bob, a king bolt, a brace bar secured to the sled top toward its rear and to the king bolt at its forward end, a slotted yoke made up of members above and below the beam of said front bob, a. pivoted cross rock bar pivoted between the yoke members and adapted to rest yieldingly against the forward side of the said bolster and beam, a spring secured at its forward end to said yoke, and an adjustable bolt for securing the rear end of said spring to said brace bar, coacting substantially as described for the purpose specified.

2., In a bob sled, the combination of the top, a rear bob secured thereto, a bolster at the front, a front bob, a king bolt, a brace bar secured to the sled top toward its rear and to the king bolt at its forward end, a slotted yoke, a pivoted cross rock bar pivoted to the yoke and adapted to rest yieldingly against the forward side of the said bolster and beam, a spring secured at its forward end to said yoke, and an adjustable bolt for securing the rear end of said spring to said brace bar, coacting substantially as described for the purpose specified.

3. In a bob sled, the combination of the top, a rear bob secured thereto, a bolster at the front, a front bob, a king bolt, a brace bar secured to the sled top toward its rear and to the long bolt at its forward end, a slotted yoke made up of members above and below the beam of said front bob, a pivoted cross rock bar pivoted between the yoke members and adapted to rest yieldingly against the forward side of the said bolster and beam, a spring secured at its forward end to said yoke, and means for connecting the rear end of said spring to said brace bar, coacting substantially as described for the purpose specified.

4. In a bob sled, the combination of the top, a rear bob secured thereto, a bolster at the front, a front bob, a king bolt, a slotted yoke made up of members above and below the beam of said front bob, a pivoted cross rock bar pivoted between the yoke members and adapted to rest yieldingly against the forward side of the said bolster and beam, a spring secured at its forward end to said yoke, and an adjustable bolt for securing the rear end of said spring to said top, coacting substantially as described for the purpose specified.

5. In a bob sled, the combination of a slotted yoke embracing the king bolt, a pressure bar disposed to brace against the forward side of the bolster and knee of the forward bob, an adjustable spring for putting tension on said yoke, as specified.

6. In 'a bob sled, the combination of a slotted yoke embracing the king bolt, a pressure bar disposed to brace against the forward side of the bolster and knee of the forward bob, a spring for putting tension on said yoke as specified.

In witness whereof, I have hereunto set my hand and seal in the presence of two witnesses.
