EDWARD L. PHIPPS, OF MILFORD, MICHIGAN.
KNOB ATTACH MENT.
SPECIFICATION forming part of Letters Patent No. 241,059, dated May 3, 1881.
Application filed January 8, 1881.
To all whom it may concern Be it known that I, EDWARD L. PHIPPs, of Milford, in the county of Oakland and State of Michigan, have invented an Improvement in Knob Attachments to Mortise Door-Latches, of which the following is a specification.
The nature of this invention relates to certain new and useful improvements in the construction of knob attachments to looks or latches; and the invention consists in the peculiar construction of the knob-shaft and its combination with devices by means of which thelatch may be operated by or released from the operation of the knobs and shaft, as more fully hereinafter described.
In the drawings, Figure 1 is a longitudinal vertical central section of my improved device. Fig. 2 is an elevation of the shaft with one knob removed and showing the sleeve. Fi 3 is an end elevation of the removable knob, showing the square recess therein.
In the accompanying drawings, which form a part of this specification, A represents the shaft or spindle, to which the knob A is secured, in the usual manner. This spindle is square, as shown, one-half its length, and is reduced at its center, as shown at (0, whereby a shoulder, b, is formed. That portion of the spindle extending from such squared part is round, as shown at c, as far as the threaded portion (1, which,in turn, is squared, leaving the threads projecting upon each corner.
B is a square slide,the exterior area of which is the same size as the mortise in the hub of the latch. Theinncr area of this slideisa trifle larger than the spindle, which latter will turn freely in the hub when the slideis withdrawn. The slide is provided with a thumb-piece or handle,f.which projects outwardly through a slot, 0, in the shank d of the removable knob 0. As this thumb-piece projects outside ofthe rose D it may be forced inward or withdrawn at pleasure. The threaded end of the spindle is inserted through the knob O, the outer face of which is provided with a rectangular and deeply-sunken recess, 0, within which there is. placed a similarly-shaped washer, g, which slips (Model) onto the squared end of the spindle and prevents the knob from turning on the shaft. A socket-nut, E, provided with a flange-head, h, to cover the recess, is then screwed onto the end of the spindle. The aperture through the bottom of the recess 6 is threaded to engage with the threaded end of the spindle, and the only use of the flanged nut is to retain the washer in place and hide therecessin theknob.
I have described my invention in one of its forms of application only; but I do not desire to confine myself to the exact construction as above set forth, as it is evident that the spindle may be reduced its entire length, so that it will freely turn within the hub of the latch or lock, except when the slide is inserted, which then fills the mortise in the hub and causes the latch to operate.
In practice the slide is forced inward when it is desired to have the turning of the knob operate the latch, and retracted or withdrawn when it is desired that the latch shall not be operated.
What I claim as my invention is 1. In combination with a knob interiorly threaded, and with an eXteriorly-thrcaded spindle which is squared at the engaging end, as described, a rectangular recess in the outer face of said knob and a similarly-shaped washer, substantially as set forth.
2. In combination with the knob O, provided with a rectangular recess,e, and with a spindle and rectangular washer, as described, the flanged nut E,substantially as and for the purposes specified.
3. In combination with the spindle A, con-' structed so that it will freely turn within the hub of the lock through which it passes, and made partly round and partly square, as shown, a slide, 15, upon said spindle, which engages with the hub of the lock, substantially as and for the purposes described.
EDWARD L. PHIPPS.
