DOOR-STOP.

Specification of Letters Patent.

Application filed March 21, 1908.

Patented Dec. 1, 1908.

Serial No. 422,394.

To all whom it may concern:

Be it known that I, DANIEL A. FIES, a citizen of the United States, and a resident of the city of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Door-Stops, of which the following is a specification.

My invention relates to door stops of the type in which a spring-operated catch is cooperatively combined with the stop, as indicated in Patent No. 646,533, of April 3rd, 1900; and it consists in certain improvements in construction which are fully described in connection with the accompanying drawings and the novel features of which are specifically pointed out in the claim.

Figure 1 is a longitudinal sectional view of a combined stop and catch embodying my invention. struction and, Fig. 3 is a longitudinal sectional view of a fragment of the invention sholwing the spring compressed by a key or too The hollow stop-body a is formed in one piece as shown, with the central bore thereof providing a spring-chamber 1) opening through therear end, and a smaller diameter portion 0 opening through the front head for the passage of a buffer-device d; said device being inserted from the rear end of the stopbody and having a circular flange 6 seating against the annular shoulder f formed in the bore. This buifendevice is positively held against removal through the front opening 0 by its flange e, and is also, as indicated in Fig. 1., positively held against rearward movement by a rear shoulder 9 formed in the bore between which latter and the shoulder f the flange e of the buffer-device is retained.

The introduction of the latter to the position described is readily provided for by making it of rubber or like yielding material, so that the flange (2 may be readily forced through the main bore 6 of the stop-body and thereafter spread out between the shoulders f and g as indicated.

The catch is which is employed in connection with the stop a to engage a keeper device m on the door in the manner indicated in Patent No. 646,533, previously referred to,

Fig. 2 indicates a modified con-' is similarly engaged in a longitudinal slot n provided in the wall of the stop-body a, and also hasan approximately right-angled footportion p which extends into the bore b and is pressedupon by a spring g in the latter to normally hold the hooked outer end 1" of the catch in keeper-engaging position. In my improved construction this foot-portion p of the catch is of substantially the same width as the slot 72, in the stop-body, so that it may be introduced laterally to the bore 1); and it is formed with a spring seat 10 adapted to so engage the bottom of the spring q as to be locked by the latter against removal when the parts are assembled. To effect this assembling and thus lock the catch, the 5 ring 9 after being placed in the bore throug the rear end of the stop-body, is compressed by a suitable tool so as to ermit the introduction of the catch-foot p through the slot n to position under the spring, which latter is then released and engages the foot under suitable tension so as to firmly retain it in the bore 1) and at the same time press the hooked outer end 7* towards the head of the stop. The inner end of the spring is referably covered by a loose washer .9 intro uced into the bore 1) ahead of it as indicated.

As indicated in Fig. 1, the stop is formed with a securing flange t at its rear end for attachment to a washboard or base-board; or it may be provided with a floor-support t as indicated 1n Fig. 2. In either 0 ening or closing the door the catch is move outward by forcible contact with the keeper 1% against the tension of the spring, as is well understood. In opening the door the shock of sto ing it is taken by the buffer-device d, Wlllc fl in addition to being positively held against undue yielding movement by the shoulder g is also yieldingly supported by the spring If desired the positive stop for the bufier device which is provided by the shoulder 9 of the preferred construction described, may be omitted, the spring q furnishing necessary su port as indicated in Fig. 2.

What claim is 2- A combined door stop and catch com rising a hollow body open at one end and aving a slot in the wall thereof, a catch having a foot portion extending through said slot into the hollow body, and a spring in the hollow In testimony whereof, I aflix my signature, body engaging the foot portion andseeuringf in the presence of't'wo'witnesses. the catch inposition under tension, said DANIEL A FIES spring extending beyond the side of the foot 5 portion whereby a,- tool may be inserted Witnesses:

through the said open end of the body to DFM. STEWART, compress the spring. W. G. STEWART.
