BOLT CONSTRUCTION.
Specification of Letters Patent.
Patented Oct. 19, 1909.
Application filed. Apri1 6, 1909. Serial No. 488,222.
To all whom it may concern:
Be it known that we, CHARLES M. Rnnvns and EDGAR FULLER, citizens of the United States, residing at Cedartown, in the county of Polk and State of Georgia, have invented certain new and useful Improvements in Bolt Construction; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to new and useful improvements in bolt construction and more particularly to that class adapted to be used in connection with railway cars and our object is to provide a swinging head for the bolt, whereby the bolt may be introduced from below through the opening prepared for the bolt by extending the head upwardly through the opening.
A further object is to so construct the head of the bolt that it will rest in alinement with the bolt while being introduced or removed from position.
A further object is to so arrange the bolt head that it will be extended to its operative position by engaging the floor of the car after it has been introduced through the opening to receive the bolt.
Other objects and advantages will be hereinafter referred to and more particularly pointed out in the claim.
In the accompanying drawings forming part of this application, Figure l is a detail elevation of a draw head and yoke such as is commonly used in connection with car couplers, showing the bolt applied to use therein, a detail section of the floor of the car being shown in position above the yoke. Fig. 2 is a detail elevation on an enlarged scale of the upper end of the bolt, showing the head in position to be introduced through an opening. Fig. 3 is a similar view showing the head in its extended position. Fig. 4 is an elevation of the upper end of the bolt with the head removed, and, Fig. 5 is a de iaill elevation of the head removed from the In building certain classes of cars, the yoke and draw head are placed in such close proximity to the floor of the car, that the bolts could not be introduced in position to attach the yoke to the draw head without removing the draw head and yoke and as these bolts frequently become broken and necessitate a great deal of time and labor to remove the bolts, we have provided our improved form of bolt and head therefor, the bolt 1 being of the usual or any preferred form and having a slot 2 at its upper end, while the lower end thereof is provided with threads 3 to receive a nut 4.
Pivotally mounted in the slot 2 by means of a rivet or the like 5, is our improved form of head 6, the rivet 5 extending through the bolt and head at one side of the center thereof, thereby forming one side of the head heavier than the other,in which event the head will swing by gravity on the rivet. The lower end of the stem 7 of the head is extended at an angle so that when the head is in its closed position, said slanted portion will be substantially in alinement with one edge of the slot 2. The opposite edges of the head 6 are provided with extensions 8 and 9, respectively, which extensions project beyond the edge of the stem 7 and protrude from the slot 2, so that when the head is in its extended or open position, the lower faces of the extensions will rest on the object through which the bolt is extended and as the extension 8 is greater in length than the extension 9, weight will be added to the head to cause the same to swing on the rivet. The upper edges of the head are inclined downwardly from the central portion of the head, the inclination of the extension 9 being greater than the extension 8, whereby when the bolt is introduced through an opening and moved into engagement with the floor 10 of the car, the curved end of the extension 9 will be engaged and the head swung on its rivet and extended parallel with the surface of the object through which the bolt is introduced.
In applying the bolt to use, the head 6 is turned to the position shown in Fig. 2 and introduced through an opening in the yoke 11 and the interposed portion of the draw bar 12, the extended end 9 of the head coming in contact with the floor 10 of the car, forcing the head to substantially the position shown in Fig. 3, when by quickly lowering the bolt, the extensions 8 and 9 will be engaged with the upper face of the yoke 11 when the nut 4 may be readily turned onto the bolt and the draw bar securely clamped in the yoke. Should the bolt become broken or it is otherwise desired to remove the bolt,
the nut 4 is removed and the bolt pushed up wardly until the head swings by gravity to the position shown in Fig. 2, when the bolt may be lowered through the opening in the yoke and draw bar. It will thus be seen that the bolt can be readily and quickly placed in position Without removing the yoke and draw bar, thus saving time and expense in applying the bolts and it will further be seen that in view of the extensions on the head, said head will. be practically as strong as when the usual form of head is used.
What we claim is:
A device of the character described, comprising a bolt having a slot therein opening out through one end, a head-member arranged in said slot and a pivot member effecting pivotal connection between said bolt and said headmember, said head-member being inclined in opposite directions upon its upper surface from a point substantially in vertical alinement with its pivot and having its lateral ends extending at different distances from said pivot, one of the thus formed extensions being adapted to extend initially beyond the slotted end of said bolt, the other of said extensions being adapted to efiect by gravity the retention of the aforesaid extension in said position, the inner end of said head-member being adapted to occupy a position parallel with the axis of said bolt and within the planethereof.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses. 1
