(3.3. WOODCOCK. DOOR OPENER.

Patented Aug. 26, 1890.

ZA/J'ZZ E 5 5 E5 LXI/5.772402 nrrrn Sr SPECIFICATION forming part of Letters Patent 435,109, dated August 26, I Application filed April 24,1890. Serial No. 349,295- (No model.) I

.To all whom it may concern:

. Be it known that I, CHARLES H. WOODCOCK, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Door-Opener, of which the following,togeth er with the accompanying drawings, is a specification sufficient-ly full, clear, and

exact to enable persons skilled in the art to which this invention appertains 'to makeand use the same. I

The object of my present invention is to afiord a simple, cheap, and efficient mechan- -ism for latching andopening doors, said mechanism being adapted to be fitted into the jamb-frames to engage the edge of the door, .as hereinafter explained also, to provide a latching device furnished with push-button studs that are revealed through the facecasing at the front, or at both front and rear, for receiving pressure to actuate or'retract the latch-dog, and a spring-actuated presser that exerts an opening impulse on the door when it is released by the retraction of the latch-dog. These objects I attain by mechanism such as shown and described, the particular subject claimed being hereinafter definitely specified.

In the drawings, Figure 1 is a front view of a door and its casings, showing the location of my improved mechanism thereon. Fig. 2 is a horizontal section of the door, jambs, and easing, showing my improved mechanism for latching and opening the door in its constructive details and in its arrangement in relation to the door and casings. Fig. 3 is a side View of the casting or box containing the latch, devices. Fig. 4 is a front View of the push-button stud and its escutcheon. Fig. 5 shows the form of the latch-dog, and Fig. 6 shows. the form 'of the rocker or lever for retracting the latch-dog.

Referring to parts, A denotes the door, B

} B the jambs, and O C the face casings or finish as employed in any building orstructure.

D indicates the casting or frame containing the latch-dog F, rocker G, and spring I. Said frame is made of suitable size and shape to contain the parts, andis adapted to fit into a mortise in the side of the door-jamb rabbet,

as indicated, its face-plated being let in flush with the rabbet surface. The latch-dog F is I formed, as shown in Figs. 2 and 5, with 'an angular latching-nose and a backwardly-extended tail. It is pivoted in the.frame at 2, so that its nose swings out through an opening in the faceplate and engages a recessf in the edge of the door. A suitable guardplate E is best provided on the door for forcing back the dog when the door closes. The rocker G is pivoted in the frame at 3, and its head 4; rests against the tail of the latch-dog. 'The spring I is confined between the tail of the latch-dog and the side of the frame, each.

of said parts beingfitted with a recess '5 for the retention of the ends of the spring, as shown. The spring I acts expausively and tends to force the dog forward into engagement with the door-recess. Alug 5 is'formed atthe tip of thelatch-dog,which strikes the inner side of the face-plate and serves to pre vent the dog from swinging too far forward; The frame D is provided with a cap-plate I), that is held by screws at e. This cap is removedin the view Fig. 2, so as to show the arrangement of the operating parts.

K indicates apush pin or stud that acts I against the rear end of the rocker and ex tends through the front casing (1,-and pre-.

sents a button or thumb-knob at the'frontof stud that acts against the head of the rocker rounded by an escutcheon H, fixed to the doorcasingby screws 72, and the, stud is shouldered or fitted with a lug or equivalent stop that strikes against the inner side of the escutch eon and thus prevents the push-button from projecting too far at the-front of the escutcheon. The inner part of the stud is best made square and enters a corresponding opening in the sides of the latch-frame, as indicated.'- In cases where the door is approached from onefside only, then only a single push-studK will be used, the rear push-stud K simply f being omitted.

At the hinging edge of the door a springactuated presser is fitted in the side of the jamb. This consists ;of apushstud M,ar-w

ranged in a suitable frame'nfz, fitted into a hole or mortise in the jamb B, and havinga spring M about its shank thattends to force rod , 8c said casing, and K indicates a push-pin or a Y the stud outward against the rear edge of the door. When the door is closed, the stud is pressed down, so that its end is flush with the rabbet surface.

A simple handle or knob P is fixed to the door for use in swinging the door or to close it; but this handle is not connected with the fastening mechanism.

The operation is as follows: When pressure is applied to one of the push-bu tton studs K or K', the rocker G is caused to press back or retract the latch-dog, and the instant its point is released from the recess f the presser M acts to throw open the door, as indicated by dotted lines, Fig. 2. My improved mechanism affords ameans whereby the opening of the door can be efiected by any action that will bring pressure on the push-stud K or K. Thus itwill be seen that a person can readily operate the mechanism, even though the hands are filled with articles.

I claim as my invention herein to be secured by Letters Patent- 1. The withindescribed mechanism for securing and opening doors, consisting of a retractible latch supported inthe jamb B and engaging a recess in the edge of the door, a

push-button stud projecting through the facecasing, with its inner end engaging for operation and retracting saidlatch when said button is pressed, and a spring-actuated presser supported in the opposite jamb- B and normally pressing against the hinging edge of the door, all substantially as set forth.

2. The combination, with the latch-frame uated presser, consisting of M, its supporting-frame 'm, and spring M,

D, that is adapted to be fitted into the side of the jamb, of the swinging latch-dog F, pivoted at 2, the rocker-piece G, pivoted at 3, the

spring I, supported between the latch-dog and frame, and the push-pin K, its inner end resting against said rocker-piece and having at its outer end a button or knob at the front of the casing, for the purposes set forth.

3. The pivoted latch-dog F, having the backwardly-extended tail and the projecting nose for engagement with a recess fin the edge of the door, the rocker G, centrally fulcrumed in the frame, with its head engaging with the tail of thelatch-dog, the push-stud K, acting against the tail of the rocker and projecting through the front casing O, the push-stud K, actingagainst the head of the rocker and projecting through the rear casing 0', and the yielding spring I, disposed beneath the tail of the latch-dog, all constructed and combined for operation substantially as and for the purposes described;

4. The combination, with the door, the jamb to which the door is hinged, and retractible-latch mechanism, of the spring-actthe rounded stud adapted for insertion into the jamb-face at vthe hinging edge of a door, substantially as and for the purpose set forth.

Witness my hand this 22d day of April, A. D. 1890.
