2' '0 aZZ whom it may concern: y,

Be it known that I, Lnoivnrir, it. linen, a citizen of the United fdtates, residing at l'ilighwood, inthe county of Chouteau, State of Montana, have invented certain new and useful Improvements in 001 do herebydeclare the following to he a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains tomalre and This invention relates to new and useful improvements in doorlock attachments, and particularly to attachments therefor which deaden the noise incident to the slamming or violently clossing the door.

One object of the invention is to provide a device of this characterwhich is readily capable of adjustment to compensate for the shrinkage of the door and door frame.

Another object is to provide a device of this character which is readily capable of attachment to the ordinary lock.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing. v

In the drawing: y t

Figure 1 is a perspective view of the lock removed from the door and having the bufffer thereon.

Figure 2 is a perspective view of the strike plate and the adjustable stop mounted thereon.

Figure, 3 is a horizontal sectional view through the front plate of the lock and the buffer, and the stop and strike plate, the parts being in the position assumed when the door is in closed position. Figure 4 is a perspective view of the strike plate, the adjustable plate being rei moved.

Figure 5 is a perspective view of the buffer removed from the lock.

Figure 6 is a fragmentary perspective view of a portion of the strike plate 23,

bolts, is a metal strip 14:, one end of which is formed witha tranversehead 15. Each arm of the head is formed with an inwardly and longitudinally extending finger or lug 16, which projects out of the plane of the head and body of the strip. The intermediate portion of the head is formed with a notch 17. The fingers or lugs 16 are engaged against the rear face of the plate 11, as seen in Figures The other end of the strip 14: is slightly wider than the main portion, as shown at 19, and is rebent at 20 to confine a rubber buffer block 21. The inner ends, at 22, of the wider part 19 the body and bent out of the plane of the body to embrace the other vertical edge portion of the face plate 11 of the lock. Thus the stem of the strip 14- engages with the plate 11 at both longer edges, with the result that the attachment is held firmly in position on the lock.

The strike plate comprises a plate 23 having the latch and lock bolt openings 24 and 25, and in which are formed the transverse elongated openings or slots 26, extending across the ends of the plate. Surrounding each of the slots 26, and on the opposite faces of the plate 28, are the roughened portions 2"? and 2'7, the purpose of which will presently appear. Extending outer edge ofthe plate 28, opposite the latch opening, 24, is the strike tongue 28, against which the latch bolt is arranged to engage, before passing into the opening Qt. The edge of the plate 23, below the tongue 28, projects outwardly to a slightly greater degree than the portion of said edge above the tongue, and a part of this portion, below the tongue, is rolled as at 29, for engage- 9 ment by the rubber buffer block 21, when the door is swung into closed position. The remaining part of the lower portion of the edge of the plate 23, is plain, as shown at 30, the portion of the edge below the part 30 being vertically aligned with the portion above the tongue.

A plate 31 is disposed on the outer wider face of the plate 23, and has a large cut out 32, resulting in the parallel end portions or arms 83, and the connecting strip 3 The arms 33 are perforated for the reception of screws, by means of which the plates 31 and 23 are secured to the door frame. The screws are adapted to pass through the slots are partly removed from from the 1 26. The faces of the arms 33 which engage with the roughened faces of the plate 23, are also roughened to prevent slipping of the plate 23, when adjusted to the proper position to be engaged by the rubber block 21. The outer ends of the arms 83 are turned laterally to engage with the outer edge faces of the plate 23, at the ends of the roughened portions thereof.

When the device is used with a door which closes in the opposite direction to that in which the device of Figure 2 is used, the strike plate has its projection 28 extending in the opposite direction, thus requiring the plate 31 to be placed against the other face of said plate. The roughened races of the arms 33 then engage with the roughened portions27 or the plate 23.

Thus, when the door is swung violently into closed position, the rubber block 21 will engage with the rolled portion 29, checking the force of the door, and deadening the sound which usually occurs when the edge of the door strikes against the door frame. As

the door and door frame change their relation, due to warping. the screws which retain the plates and iii are partly withdrawn, and as the case requires, the plate 23 slipped forwardly or haelnvardly, after which the screws are again tightened to cure the adjusted relation of the plates.

What is claimed is:

A buffer for a lock comprisinga strip adapted to be disposed transversely of the face ot the face plate of a lock casing between the latch and lock bolt openings. one end of the strip being formed with a head and projections engaged with the rear face of said face plate. and ollset lingers on the other end embracing the opposite edge of: the plate. the last-named end oil. the strip being rehent to confine a resilient hloeh.

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