'ro ALL wHoM IT'MAY conocen:

Be it known ,that I, DARIUS SKIDMORE, ot` Seneca Balls, in the county of Seneca, andrState of New York, l

did invent a new and useful Improvement in Fastening the Shanks of Door Knobs, for which Letters Patent of tli'e United States were granted on July 15, 1862; and I do hereby declare that the following is a full and exact Adescription thereof, reference being made to the accompanying drawings, making part of thisspecication.

Figure 1 is e central longitudinal section of a door knob arranged in my improved manner and applied to a. door.

Figure 2, a perspective view of the socket or sleeve and the rose or angc. Figure 3, a view similar to I ig. 2,'*but showing a modification.

Likeletters` of reference indicate corresponding parts in all the figures.

I'The usual way of fastening the shank of the knob Ato the spindle that passes through the door and operates the'bolt, isfbyssmall screw that passes in through both to couple them togethert By the continual and violent action-of the door knob, in turning, theserew frequently becomes loose, climbing up, as it were, by its threads, 'from 'the socket in which it rests, and falls out. lhis difliculty is aggravated by the position of the screw, which is always angular in the shank. It is the object of my invention to obviate this difficulty by securing the shankand spindleftogether in such a manner that they can never become uncoupled by accident.

` As represented in-the drawings, the general construction of thc door knob is as usual, consisting of hand knobs, A A` secured to Shanks, B B, which are coupled to the spindle C, that passes through the door and operates the bolt. The usual-holes, a a, are made in an upright position iii-the spindle and shank, which, when coincident, receives the couplingl device. This device, instead of being in the form oi' a screw, as usual, is siniplyaI plain, smoothpin, b, which is dropped into the holes, and retains'its place simply by its own gravity, its upright position, as shown in the drawings, being such that it Acannot fall out. 'lhe advantage of this plain pin ovcrithe ordinary screw coupling is so obvious that reference thereto ishardly necessary.` The screw is constantly working out under violent turning action, climbing up as it nere, more and more at cach turn, upon its threads, till it finally falls out. v There can be no such working out of place in the employment of the plain pin, since it has no threads on which to rest, but constantly retains its place by reason of its own gravit-y. Ovciuthe sha-nk B yfits the rose or iiange E, secured to the door Vby screws in the usual manner. In figs. 1 and@ the rose is shown with a socket or sleeve, D, projecting outward sufficiently to 'cover the top of the coupling pin. In iig. 3 the socket or sleeve is shown as made separate and independent ot' the rose, and resting simply on the shank.

This is simply an equivalent of the for-1n at iirst described; and in fact any forni of the rose that will cover thc pin may be employed. The socket or sleeve vD has a hole, d, corresponding in position with the coupling pin.

lVhen the pin is to be applied, thel hole d isbrought in coincidence with hole a, when the pin is dropped in place, vand the sleeve is turned around'suiicientl'y to remove d from a, as shown. Thus arrangedftlie coupling pin is always securely held in position, and can be; removed only by design. In storage and transportation, before the knob is secured to the door, this socket or -sleeve will always hol'd thc pin'in place,fcvon if it should become inverted.- Thus the articles can be securely packcth By avoiding the use of the screw bythe substitution of 'the plain pin, there will heno grinding of the head of the coupling against the inner periphery of the socket of the sleeve. v

What I claim as my invention, and desire to secure hy Letters Patent, is

l Covering or enclosing the end of the coupling pin of the knob, shank, and spindle, wholly or partially, by

the socket or eye ofthe rose, substantially as and for the purpose herein specified.

I also claim a smooth coupling pin, b, retained in its hole by its gravity, in combination with the covering thereof by the socket or sleeve of the rose, substantially as herein set forth. K DARIUS SKIDMORE.
