wherein The nature and advantages of the invention will be better understood when the following detailed description ,isread in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and

v Figure 1 is aside elevation of a buffer.

Figure 2 is a transverse sectional view taken on the line 2-2 of Figure-'1.

' Figure 3 is an enlarged sectional view through thedoor stop showing'the buffer associated therewith. v

Figure 4 is a sectional view through the door frame showing the door closed and bearing against the uffer.

Referring to the drawing in detail, indicates a door frame forming part of which is the usual door stop or strip 11, the

I door being indicated at 12. The buffer at l3'and received within the metallic mem-.

ber 14 of a U-shaped flange in cross sec-- forming the subject matter of thepresent invention is adapted to be associated with the door stop or strip 11, and designed to extend along the entire length thereof. The strip 11 is further provided with a long groove 12' to accommodate the buffer in a .manner to be presently described.

The buffer is made from a single length of rubber or other suitableyieldable material against which the door, is to close to prevent slamming'of the door as will be readily understood, and when the material from.

which the buffer is formed is thus folded, the ends of the material are brought together in face to face contact as indicated tion. The parallel portions of this metallic member are perforated to provide projections or the like 15 which are embedded in the adjacent portions of the yieldable mate rial 13 to prevent the latter from slipping or becoming casually separated from the metallic member 14. The width of the metallic member is 'thesame as the .width of the groove 12', so that when the member is fitted in the groove it is wholly disposed metallic member 14 and the yieldablemate- -within the latter, with that portion of the rial, so that the buffer in its entirety is held fixed with relation to "the strip lland also to the door frame 10. The buffer-is very simple in construction and can be manufactured and sold at a very nominal cost and can be used with any door frame .by simply providing a groove 12 in the door stop or stri l1. 1

il it is believed that from the foregoing description, the nature and advantages of the invention will be readil a'ppar cut, I desire to have it understood do not limit myself to what is herein shown and described and that such changes. may

that I be resorted to when desiredas fall within the scope of what is claimed.

Having thus described the invention' I" claim: I

1. In combination, a door stop comprising a strip secured to the door frame and havin a longitudinal groove, a .door bufler forme from a single piece of yieldable material folded upon itself and having its adjacent ends arranged in-face to face contact and fitted in said groove, the intermediate portion of said bufi'er projecting be- {0nd the strip and arranged to be engaged y said door, and the ends of. said strip being secured in the cove by the means utilized in 'ezsecuring t e strip to the door frame. v

2. The combination with a door stop comprising a stri having a longitudinal groove,

of a door bu er including'a single piece of yieldable materialfolded upon itself, a metallic member .of U-shaped formation in cross section receiving the free edges of said.

yielclable member, and means for securing extensive in length with the length of said the buffer in its entirety Within the groove yieldable material, and projections extend- 10 of the door stop. ing inwardly from the metallic member and 3. A door buffer including a length of embedded in the adjacent portions of the afieldable material folded upon itself with yieldable material to'hold the parts fixed its marginal edges in face to face contact, relatively. a metallic member of U-shaped formation In testimony whereof I aifix my signature. in cross section receiving said edges and co- APOLLONY ZANELLA.
