Nrrnpfn STATES CHARLES HERBERT OOUMRAUGH, OF ROCHESTER, NEV YORK.

DOOR-HOLDER.

SPECIFICATION forming part of Letters Patent N0. 629,753, dated July 25, Application led January 7,1899. Serial No. 701,452. (No model.) l

has for its object to increase their efficiency;

and it consists in the construction herein described and pointed ont.

In the accompanying drawings, Figure 1 is a side elevation of the device, an inoperative situation being indicated by dotted lines. Fig. 2 is a longitudinal section. Fig. 3 is a plan. Fig. 4 is a section on line 4 4 of Fig. 3. Fig. 5 is a similar section of a modification, and Fig. 6 is a partial perspective showing mode of attaching a spring.

Numeral 1 denotes a plate secured to the foot of a door 2 by screws 3.

4 indicates a lever made approximately semicylindrical in cross-section, as usual, and provided with a trunnion 5. The plate has in its lower edge an inclined slot 6 to receive the trunnion and furnish its bearing.

The plate 1 and the door-holder lever 4 are operatively connected by a spring 7, which when not in operation lies within the concavity of the lever. The spring is attached to the end of the plate 1. For this purpose the plate is conveniently provided with a notch S to receive the hooked end of the spring. Said notch is situated adjacent a similar notch 9, formed in the lever.

lO (see Fig. (i) denotes a bend in the spring contiguous the notched portions of the plate and lever.

by the spring to an inoperative situation, and thereby avoids the use of special stops or pins. The bend also facilitates JIthe passage of the wire between the notched`parts, as indicated The hooked end of the spring is seated in a groove 4, so as not to interferewith the close application of the plate to a door. \The opposite end of the spring is secured tothe end of the lever 4 by being bent about the same, as shown in Fig.

This bent portion of the spring constitutes a stop for the lever when thrown v 2. Its end 7 is also passed through the wall of a socket 12and through a. friction-block 8, of rubber or other material, seated in said socket. Being thus secured and substantially as indicated, it holds the friction-block in its seat, the necessity of a separate block or rubber-retaining device being thus obviated. Any equivalent means of using the end of the spring-wire to secure the spring to the end of the lever and also serve the further.

function of fastening the friction-block to the lever m ay be employed. Preferably the bearing end of the lever is bent upwardly, as shown at 4', so as to be approximately parallel with the iioorwhen the leveris in operation and so that the bearing-face of the friction-block will be held parallel with the floor-surface.

By attaching the spring to the end of the lever, as set forth, the leverage is increased as compared with prior devices which make this attachment back of the friction-block.

By attaching the spring at the end of the iiXed plate the angle between it and thelever when the latter is thrown down to bear on the door, as indicated at Fig. 1, is made as large as practicable and its effective power ythereby increased.

The described means of connecting the spring to the plate and lever avoids the necessity of pins for the purpose, thereby saving metal and avoiding the breakage incident to the use of pins.

As shown in Fig. 5, the plate 1 has an offset' 14, provided with a wing 15, situated parallel to the main part of the plate.

Two open inclined slots 6 are formed-one in the plate and one in its wing-to furnish bearings for the two trunnions of a bar or lever 4. The bearing-slots, Whether one or two are used, are inclined with respect to plate and lever, so that the spring tends to draw bearings. The plate, lever, and spring being connected as set forth can be rapidlyI and easily assembled. All pins or small projections are avoided, except, of course, a necessary trunnion, and the greatest leveragepracticable in this particular class of doorh'olders is attained. y

I-Iaving thus described my invention, I claim- 1. In a door-holdin g device the combination -the lever trunnion or trunnions into said IOC of the plate iiXed to the door, the lever provided With a trunnion-bearing in the plate, and a spring operatively joining the plate and lever, one end of said spring being attached at the extreme opposite end of the lever to increase the leverage vand obviate the use of a special spring-holding lug, and a frictionbloek secured to the end of the lever by means of the spring.

2. Inadoor-holding device the combination of the plate lined to the door, the lever provided with a trunnion-bearing in the plate, and a spring operatively joining the plate and lever, one end of said spring being attached to the extreme opposite end of the lever, and a friction-block secured to the end of the lever by the means which secured the spring to the saine, said lever having an upwardly-bent portion provided, with a block-seat and with a groove to receive the spring-Wire extending around its end.

3. In a door-holding device the combination of a plate, a lever, a sprnglbearing on tlie' end of the lever and a friction-block, said block being held to the lever by the spring; whereby the spring is fastened directly to the lever and a special lug avoided, said spring'- l fastening also performingthe additional func'- tion of holding the friction-block.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
