Description
UNITED STATES PATENT OFFICE.
JOSEPH H. MANNAS, OF SI-IIPPENSV'ILLE, PENNSYLVANIA.
SLED-BRAKE.
Application filed February 20;, 1911.
To all whom it may concern Be it known that I, JOSEPH H. MANNAS, a citizen of the United States, and a resident of Shippensville, in the county of Clarion, State of Pennsylvania, have invented certain new and useful Improvements in Sled-Brakes, of which the following is a specification, reference being had to the accompanying drawings,
This invention relates to certain new and useful improvements in sled brakes of that kind, automatically operated by the tongue of the sled. when the draft animals exert a backward pressure on the tongue, and the primary object of my invention is to provide a sledv brake of this general character, of a simple and inexpensive nature and of a compact and durable, construction, arranged so that the brake can be instantly brought into action upon the release of a detent, the tongue again being automatically looked upon the operation of the self-acting detent.
With these and other objects in View, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claim, it being further understood that changes in the specific structure shown and described may be made within the scope of the claim, without departing from the spirit of the invention.
In the accompanying drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views: Figure 1 shows a top view of the forward runners of a bob sled with parts broken away equipped with a sled brake embodying my invention. Fig. 2 shows a lengthwise sectional view. Fig. 3 is an enlarged detached detail disclosing the detent as used in my present invention.
In carrying out the aim of my invention, I provide a sled brake especially adapted to be used in connection with bob sleds, so constructed that the brake can be instantly thrown into operation. While I have only shown the fore runner of a bob sled, it should be understood that the rear runners can also be provided with a brake, constructed according to my invention.
In the accompanying drawings, the numerals 1, 1, designate the runners of a suit able bob sled which are connected by means of the perch 2, as is usual in sled-construe tion. The perch is braced by means of the Specification of Letters Patent.
Patented Aug. 19,1913. Serial No. 609,676.
Secured; near the forward end of the stub tongue 6 is the collar 13, while secured near the rear end, is the collar 14, and slidably held below these collars 13 and 14, is the tongue 15, to which the draft animals are secured. Intermediate of its ends, the stub tongue 6,. has the bolt 16 slidably held within the slot 7 while near the rear end is the bolt 1?, working within the slot 8. The bolt 1'? is given further support by means of the hammer strap 20. Near the rear end, the tongue 15, is provided with the rub plate 19, the end 21, of which is adapted to strike against the plate 10 as shown in Fig. 2. The tongue 15 as well as the rub plate 19 is provided with a bolt opening 23, arranged at times to register with the bolt opening with in the stub tongue, as shown in Fig. 3.
Secured to the perch 4, as shown in Fig. 3, is the bolt 24, which gives pivotal support to a lever 25 at its end carrying a pin 26, engaging the bolt 27, which bolt is arranged to reciprocate within the bolt openings of the stub tongue and pole. At its end the lever 25 has a flattened port-ion 28, and arranged to frictionally engage this flattened portion 28, is the arcuate head 29 of the de tent 30, this detent being pivotally held upon the bolt 31. The detent ends in the car 33, from which extends a suitable operating cord or strand 34. I-Ield adjacent to the detent 30, is the stop pin 32, the arcuate head 29 engaging this pin 32, when said detent is carried in an upward position. In raising or lowering the detent, a rocking movement is imparted to the lever 25, resulting in the bolt 27 being carried in or out of the bolt opening 23, within the pole 15.
Secured to the rear end of the pole 15 is the pin from which extends a connecting member 36. This connecting member is in the form of two connected bars which have their ends spread to engage the pins 35 and 37 in the manner shown in Fig. 1.
Secured to the perch 2, at opposite ends, are the bearing collars 39, and revolubly held within the collars 39, is the rock shaft 40 having the cranks 41, at its ends, and the intermediately positioned arms 42. The arms 42 carry the pin 37, giving support to the connecting member 37. Secured to each runner at, a suitable point are the brackets 43, and slidably held below each bracket is a brake 45, the upper end of which is secured by means of a bolt 46,. to one of the cranks 41, this construction being shown in Fig. 3. As shown in said figure the perch 2, gives support to a pin 50 to which is pivotally connected the reach bar 51 secured to the rear sled member, as is usual in bob sled construction. Normally the detent 30, extends in a horizontal plane as shown in Fig. 3, in which position the arcuate head 29, tilts the lever so that the bolt 27 securely holds the pole 15, to the stub tongue. As soon as it is desired to apply the brake, as when the sled is going down hill, the operator pulls up the strand 34, to bring the detent in a vertical position, resulting in the bolt 27 dropping out of the opening 23. As soon as this occurs, the tongue 15 slides backward being guided by the bolts 16 and 17, which results in a rock ing movement being imparted to the rock shaft 40, so that the arms 42 and the connected bars are forced downward resulting in these members 45 cutting into the ice and snow to check the progress of the sled.
A sled brake constructed according to my invention is simple and inexpensive, and both durable and eflicient in operation, and the brake can be thrown into operation with ease, accuracy and despatch.
Having thus described my said invention what I claim as new and desire to secure by United States Letters Patent is:
In combination with a sled having a brake mechanism attached thereto, means for operating the brake mechanism comprising a slotted stub tongue attached to the sled, a draft tongue slidably mounted upon the stub tongue having an opening, a yoke attached to the stub tongue and extending over the draft tongue and normally closing the opening therein, a bolt slidably mounted in the stub tongue and adapted to enter the opening in the draft tongue, a lever fulcrumed to the frame and pivotally connected with said bolt, and a detent pivoted to the frame and having a cam end which engages the end portion of the said lever.
