ANDREW HAYES, OF BUSKIRK BRIDGE, NEW YORK.
BOLT.
SPECIFICATION forming part of Letters Patent N 0. 691,765, dated January 28, 1902.
Application filed May 9, 1901. Serial No. 59,415. (No model.)
To whom it may concern.-
Be it known that 1, ANDREW HAYES, a citizen of the United States,'residing at Bnskirk Bridge,in the county of Washington and State of New York, have invented certain new and useful Improvements in Bolts; and I 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.
This invention relates to bolts; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a side View of the bolt. Fig. 2 is a plan view. Fig. 3 is a longitudinal section through one end portion of the bolt. Fig. 4 is a detail View of the end portion of the bolt. Fig. 5 is a plan view of the same. Figs. 6 and 7 are plan views of the locking-collar from above and below, respectively. Fig. 8 is a section taken on line 00 w in Fig. 6. v
A is a cylindrical bolt which is provided at one end with a head a of any approved form. The end of the bolt has a T-shaped projection b, the shank b of which is rectangular and smaller than the cylindrical bolt A;
O is a locking-collar which has a round hole 0 at its lower part formed part way through it and which slides over the end portion of the bolt A. At the bottom of the hole 0 there are two inwardlyprojecting shoulders c,
' which bear against the end of the bolt A and prevent the collar from being slid too far onto it.
t D is an oblong slot or hole in the upper part of the collar. The length of the slot is-the same as the diameter of the hole c,and its width is the distance between the shoulders 0'. Two sockets e are formed in the upper side of the collar above the shoulders c, and these sockets are large enough to receive the head of the T-shaped projection 12 on the end of the bolt. 7
' In order that the collar 0 may be slipped over the end portion of the bolt, the T-shaped projection is made of such width that its head does not project beyond the periphery of the bolt. The exterior of the collar 0 is preferably conical, the smaller end being arranged downward.
F is a spring-casing which is provided with an internal flange f at its lower part and a hole f,.which slides over the bolt A. The casing is. preferably conical and of the same taper as the collar 0, the lower end portion of which it incloses.
G is a spiral spring arranged in the casing F, between the flange f and the smaller end of the locking-collar.
H represents portions'of two elements or parts of a machine which are to be connected by means of the bolt-,which is passed through holes in them. I
The locking-collar is pressed down on the spring until the head of the T-shaped projection projects through the slot D in the collar, and the collar is then turned one-quarter around with the thumb and fingers and is released, sothat the spring presses the sockets 6 into engagement with the ends of the head of the said T-shaped projection, and thereby locks the bolt. The collar is released by pressing it against the spring and then revolving it until the slot is in line with the head of the- T-shaped projection.
The spring-case can be dispensed with in some cases; but its use is preferred in all ex posed situations, as it protects the spring from dirt and injury. The conical form of v the spring-case and the collar prevents them from being normally in close contact, so that they do not become rusted together, and yet leaves only a small opening between them. The-conical form also guides the parts while being placed in engagement with each other, so that the collar is not liable to strike the top of the casing.
What I claim is- 1. The combination, with a bolt having a T-shaped projection at one end the head of which does not project beyond the periphery of the bolt; of a locking-collar provided with a hole which is slidable over the said projection and the end portion of the bolt, said collar having also shoulders at one end of the 2. The combination, with a bolt provided KOO with a T-shaped projection at one end; of a ders forreceivingthesaid head; andaspring conical spring-case encircling the bolt and interposed between the said flange of the having an internal flange at its smaller end; spring-case and the smaller end of the said a conical locking-collar which projects into 1 collar, substantially as set forth.
