JOHN SCHRUTH ALBERT SCHRUTH EDWARD SCHRUTH AND WILLIAM ENGEL OF
. Specification of Letters Patent. Patented Nov. 28 1911.
Application filed April 1 1908 Serial No. . Renewed October 27 1911. Serial No. .
To all whom 'it may concern:
Be it known that we JOHN SCHROTH ALBERT SCHRUTH EDWARD SCHRUTH and WILLIAM ENGEL citizens of the United
5 States of America and residents of Pepin in the county of Pepin and State of Wisconsin have invented certain new and useful Improvements in BobSleds of which the following is a specification.
10 This invention relates to new and useful improvements in bob sleds and it is an object of this invention to provide a device of this character which will be an easy goer.
It is also an object of the invention to pro
15 vide a novel device of this character wherein the runners are movable with relation to the body.
Furthermore an object of the invention is to provide a device of the character noted
20 which will possess advantages in points of simplicity efficiency and durability proving at the same time comparatively inexpensive to manufacture.
With the foregoing and other objects in
25 view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.
In describing the invention in detail ref
30 erence will be had to the accompanying drawings forming part of this specification wherein like characters denote corresponding parts in the several views in which
Figure 1 is a fragmentary view in per
35 spective of the invention the nonessential features being omitted and the body being indicated in dotted lines and Figs. 2 3 4 5 and 6 are views in perspective illustrating various details of the invention.
40 In the drawings A denotes the front sled
of the bob and B the rear sled. Both of
these sleds are similar in construction ex
cept the caps that hold or connect the run
ners and raves which are slightly different.
45 It will therefore be understood that with
the exception of these caps the description
of one of the sleds will be applicable to the
other. Each sled comprises a runner 1 and
a rave 2 connected intermediate their
50 length but preferably adjacent the rear
thereof by the brace 3. This brace may be
of any desired configuration but it has been
found best that it be formed as illustrated
in the drawings wherein an approximate U
55 shaped brace is illustrated having its stems
arranged on an incline the ends of the stems being secured to the runner 1 while the base portion of the brace supports the rave. To the under surface of the runner is secured the ordinary shoe 4. Resting on the rave 60 2 above the brace 3 is a block 5 and on this block 5 rests a bearing 6. This bearing 6 and the block 5 are held in position by the bolts 7 which pass through the bearing block rave and brace 3 said bolts being 65 held in position by the nuts 8. Positioned above the bearing 6 is a cross strip or beam 9 which has secured to its under face the cast plate 10. Depending from this cast plate 10 are the series of spaced perforated 70 ears 11 and 12. The ears 12 straddle the bearing 6 and the perforations of these ears register with the perforation of the bearing and through the bearing and the ears passes the trussrod 13. This rod also passes. 75 through the ears 12 before refererd to.
The plate 10 may be secured to the beam in any desired manner preferably by screws passing through the perforations 14 in the base thereof. This plate may be of any de 80 sired form but it has been found best that the same be provided with longitudinal side flanges 15.and an end flange 16. The flange 16 is intended to bear against the end of the beam while the flanges 15 contact with the 85 sides of the beam. This structure reduces the strain on the securing screws to a minimum and holds the plate against any possible movement on the beam more especially the end flange 16 as under' ordinary 90 circumstances the plate has a tendency owing to the strain thereon to move inwardly on the beam.
Positioned between the ears 11 is a knuckle 17 which has a longitudinal open 95 ing or bore 18 through which the trussrod 13 passes it being understood of course that this knuckle is positioned between the ears before the trussrod is applied. Beneath the bore 18 adjacent one end thereof the knuckle is provided with a transverse bore 19. This bore is at the inner end of the knuckle when in applied position and is arranged on an incline toward the runner. Passing through this bore 19 is a brace rod 20 which is secured to the rave 2 adjacent its forward end. The opposite end of the brace rod 20 is threaded and this threaded portion is engaged by the nut 21 which bears against the knuckle 17. By turning
this nut 21 the tension of the brace rod may be regulated as the requirements of practice may necessitate. The opposite end of the knuckle 17 is provided with the inwardly
5 converging transverse bore 22 through which passes the brace strip 23. This brace strip 23 is formed of a continuous piece and has its ends secured to the stems of the brace 3 hereinbefore referred to. This attach
10 ment of the brace 23 to the brace 3 is preferably effected by having the free ends of the brace 23 terminating in eyes 24 through which pass the headed bolts 25 engaged by the nuts 26 as is thought to be fully shown
15 in Fig. 1.
To the cross beams 9 the body of the bob is secured. By the structure set forth a bob sleigh is .provided wherein the supporting sleds are movable with relation to the body. This arrangement provides a bob sleigh which rides very easily in view of the fact that each sled is movable independently of the other and of the body the advantages of which are believed to be apparent without 25 the necessity of an enumeration thereof.
The forward end of the front sled is slightly higher than the front of the rear sled in fact the forward end of the front sled is elevated slightly above the body. The rave 2 and runners 1 are connected by the cap 27. This cap snugly engages the top and side of the rave and the bottom and side of the runner and is held thereto by the bolts 28. The top of the cap has upstanding perforated spaced lugs 28' between which fits a bearing 29 secured to bar 30 and is pivotally secured to the cap by the bolt 31 which passes through the lugs 28' and the bearing 29.
The raves and runners of the sleds B are each connected by the cap 32 which snuglyengages the same and is securely fastened thereto. This cap 32 has its point provided with a perforation 33 through which passes
a strap 34. This strap 34 is secured to the 45 under surface of the body as shown in Fig. 1. This is done in order that the downward movement of the rear sled can be controlled or limited as in practice it has been found that the same freedom of movement should 50 not be permitted the rear sled as is permitted the front sled.
We claim :
In a sled the combination with runners raves connected to the runners and means 55 supporting said raves on said runners of a truss rod extending from one rave to the opposite rave transversely extending plates pivotally mounted on said truss rod said plates having depending lugs through which 60 said truss rod passes knuckles on said truss rod disposed between said depending lugs each of said knuckles having two lugs brace members looped through one of said lugs and connected to said means supporting said 65 raves and brace members passing through the other lugs on said knuckles and connected to the forward parts of said raves said last mentioned brace members being adjustable with respect to length whereby the 70 wear upon the pivotal connections between said raves and said plates may be taken up.
In testimony whereof we affix our signatures in the presence of two witnesses this 7th day of December 1907.
