R. S. BOUDROT.

DRAWER KNOB.

APPLICATION FILED MAR. 30, 1911.

Patented Feb. 6, 1912.

REAMIE S. BOUDROT, OF NEWTON, MASSACHUSETTS.

DRAWER-KNOB.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed March 30, 1911. Serial No. 618,035.

To all whom it may concern:

Be it known that I, REAMIE S. BOUDROT, citizen of the United States, residing at- Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Drawer-Knobs, of which the following is a specification.

This invention comprehends certain new and useful improvements in drawer knobs or pulls, and the invention has for its primary object an improved construction of disappearing knob which may be left flush or entirely within the outer margin of the part to which it is attached, when not required for use, and easily brought out to a projecting and operative position, when desired, the device being composed of co nparatively few parts that may beeaslly manufactured and readily assembled and which will occupy very little space when in retracted relation to each other.

With this and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawings, in which: Figure 1 is a perspective view illustrating one application of my invention; Fig. 2 is a longitudinal sectional view of the device, with the finger-piece in its protruding operative position; Fig. 3 is a sectional side elevation with the finger-piece retracted into the front of a drawer; Fig. 4: is a rear view of the device; and, Fig. 5 is a detail perspective view of a sleeve carried by the finger-piece.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

In carrying out my invention, the front 1 of a drawer or other part to be equipped with my improved knob, is bored to provide an opening for the reception of a tubular casing 2, the outer end of which is flanged,

as at 3, so as to engage the outer face of the drawer front. The inner end of the casing 2 is provided with two diametrically opposed tangs 4 designed to be inserted through and up-set or riveted in apertures 5 formed in 2. preferably bulged back plate 6 which is designed to be secured by screws or similar fastening devices to the rear face of the drawer front, so as to securely hold the casing in place. A stem 7 projects forwardly from the back plate 6, to which it is secured, said stem being disposed centrally within the casing 2, as shown.

8 designates the finger-piece or knob proper, which may be of any desired configuration or shape, the same being annularly grooved in the present instance to provide a convenient fingerhold. The fingerpiece 8 is formed with a central bore, in which a sleeve 9 is secured, said sleeve being adapted to slip over the stem 7 and being provided with any desired number of longitudinal slots 10, said slots being two in number in the present instance and arranged, in diametrical relation to each other. The slots are closed at their inner ends, that is, they stop short of the inner end of the sleeve or bushing 9 and merge at their outer ends into notched recesses 11 that are oppositely disposed, as best illustrated in Fig. 5. A pin 12 is secured to the stem 7 and is received in the slots 10, said pin being designed to ride upon and be retained in the notches of the end recesses 11 when the knob or fingerpiece 8 is pushed inward to its inoperative position and given a slight rotary movement.

A spring 13 is coiled around the stem and sleeve and bears expansively against the finger-piece 8 and back plate 6 so as to tend to cause the finger-piece 8 to protrude out of the front end of the casing 2. Preferably, the outer end of the spring is seated in a socket 14 formed for it in the inner end of the finger-piece. The outer face of the finger-piece 8 is preferably slightly depressed or dished, as indicated at 8 whereby one may, by inserting a finger within the dished portion of the finger-piece, easily turn the same so as to cause the notched recesses 11 to ride out from the pin 12 so as to admit the latter to, or remove it from the longitudinally extending slots 10 in the operation of moving the finger-piece 8 to inoperative and operative positions.

From the foregoing description in connection with the accompanying drawing, the operation of my improved disappearing knob will be apparent. In the practical use of the device, after the parts are secured to the front of a drum or the like, they may be pressing the finger-piece inwardly, giving it a slight turn in one direction so that the pin 12 will engage the notches of the recesses 11 at the outer ends of the slots 10. When it is desired to pull the drawer out, it is only necessary to give a slight turn to the finger-piece in the opposite direction, so as to permit the pin 12 to register with the slots 10, whereupon the spring 13 will be permitted to act, as before specified. It is obvious that the parts may be cheaply manufactured and very readily assembled.

Having thus described the invention, what is claimed as new is:

1. As a new article of manufacture, the herein described disappearing draw knob, comprising a tubular casing, a back plate secured thereto, a stem projecting into the casing from the back plate and provided with a transverse pin, a finger-piece mounted to slide on the stem and provided with a sleeve having a slot accommodating the pin,

the sleeve being also formed with a recess communicating with the outer end of the slot and designed to accommodate the pin upon the initial and a partial rotary move- I ment of the finger-piece, and an expansion spring encircling the sleeve and stem and pressing outwardly upon the finger-piece.

2. As a new article of manufacture, the herein described disappearing knob, comprising a stem, a support therefor, the stem being provided with a transverse pin, a finger-piece provided with a sleeve adapted for insertion over the pin and formed with slots accommodating said pin and closed at their inner ends and terminating at their outer ends in notched recesses, and a spring bearing against said finger-piece and tending'to move it outwardly.

3. As a new article of manufacture, the herein described disappearing knob, comprising a stem provided with a transverse pin, a support for the stem, a knob provided with a rearwardly opening bore, a sleeve secured in said bore and provided with a longitudinally extending slot acdbmmodating said pin the inner end of the slot being closed and the outer end opening into a transversely extending Wall designed to accommodate the pin upon the inward and a partial rotary movement of the fingerpiece, and a spring bearing against said finger-piece and tending to move it outwardly.

4. As a new article of manufacture, the herein described disappearing drawer knob comprising a tubular casing formed at its outer end with a flange, a back plate secured to the opposite end of the casing and provided with a forwardly projecting stem disposed centrally of the casing, the stem being provided with a pin, a finger-piece provided with a sleeve mounted to slide on the stem and formed with a longitudinally extending slot accommodating said pin, the slot being closed at its inner end and opening at its outer end into a transversely extending wall, and an expansion spring encircling the sleeve and stem, and bearing upon the back plate and finger-piece, the finger-piece being formed at its inner end with a socket receiving one end of the spring.

In testimony whereof, I aflix my signature in presence of two witnesses.
