BUFFER Filed June 13. 1929 i a w 3 7 JEUH Rees Be 72072 Patented June 9, 1931 UNITED STATES PATENT OFFICE REES BEYNON, OF CHICAGO, ILLINOIS, ASSIGNOB/TO DRYDEN RUBBER COMPANY, OF

CHICAGO, ILLINGIS, A CORIPORA'I'ION OF ILLINOIS Y J BUFFER Application filed June 13,

This invention relates in general to buffers for doors and other closures and more specifically to buffers for automobile doors for cushioning the closin impact and preventing rattling when the door is in the closed position.

Heretofore it has been the practice to provide buffers that are held in place by means of a screw which either extends through the buffer block only or through a container which supports the buffer block. In the former type no adjustment for wear is provided whereas, in the latter type the butter block is usually slotted so that it may be adjusted for wear. In either t pe it is necessary to loosen the screw when it is desired to replace a worn bufier with a new one or adjust a lender which has become worn. It is obvious, therefore, that with frequent loosening and tightening of the screw, the screw hole in the door casing will become worn to such an extent that it will be impossible to tighten the screw. In other types of buffers the screw is concealed beneath the buffer and usually rigidly secures a retaining member having flanges for engagement with the buffer block to hold it in place. As these flanges are in frictional contact with the rubber it is obvious that the closing and opening of the door will cause the rubber to wear at the contact points and the block will become loosened and if not lost, will perform its function less efliciently.

It is therefore a primary object of this invention to provide a buffer which may readily be detached from its supporting screw, without having to loosen the screw, when it is desirable to replace a worn buffer block with a new one.

It is also an object of this invention to provide a buffer in which the mounting screw is concealed from view and contact points between the buffer block and screw are of metal.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the ac companying drawings. 8

The invention (in a preferred form), is

illustrated in the drawings and hereinafter more fully described. I

On the drawings: v

Figure 1 is an elevation view showing a door jamb equipped with a buffer embodying this invention.

Figure 2 is a horizontal view partly in section, showingthe buffer and the relation of a door thereto.

Figure 3 is a bottom View of the buffer showing the attaching means therein.

Figure 4 is a horizontal section through the buffer and door casing.

As shownon the drawings: r In the application of this invention t automobiles it is preferable to mount the buffer in a door jamb 1, which israbbeted at Q'for receiving the striking portion of the door. In the face 3 of the door jainba socket 4:, which opens into the rabbeted edge5, is

provided. This socket is made of suitablesize and shape to snugly receive a buffer block 6 and hold it in the proper position.

' The buffer block 6, consists of a resilient body which is moulded into any desired shape; In the present instance, however, it is shown to consist of a block having a rectangular portion formed by the parallel sides 7 and .9 which are disposed at right angles to an end 801 An arcuate end 8, which is disposed oppositely the end 8a, is formed by the continuation of the sides 7 and 9 in a direction away from the end 8a. When the buffer is in place in the socket 4t, the rectangular portion projects past the rabbeted edge 5 and into the rabbeted portion 2 of the door janib to form a cushion against which the door 3a is closed.

The buffer block 6 has moulded into it the female member 10 of a snap. This member has a circular spring 11 which is secured in such a manner that it will engage in a groove 12 of the male member 13 of the snap. The male member of the snapv forms the head of the mounting screw 14. It is, therefore, obvious that the contact be tween the mounting screw and the buffer isinetal to metal, with the result that there will be no wear of the buffer at this point.

In the use of this invention the mounting screw including the male member of the snap on its head is screwed into the door jamb at the proper place within the socket. The buiier is inserted into the socket and the female member of the snap comes into contact with the male member of the snap. The application of further pressure will cause the spring 11 to snap into the groove.

12 and hold the buffer tightly in the socket l. As the buffer becomes worn with use it may easily be removed and a new one snapped into place.

It is therefore, evident that by the use of this invention an improved buffer is provided which is easily installed and easily removed for replacement. There is no frictional contact of metal to rubber and the buffer will always be held tightly in place.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted,

otherwise than necessitated by the prior art.

I claim as my invention:

In combination, a rabbeted door jamb having a socket in its face and rabbeted edge, a resilient buffer member registered in said socket with a portion projecting outwardly beyond said rabbeted edge, a male snap fastener member comprising a mounting screw on the door jamb and in the socket, said screw having a head portion with a circumferential groove formed therein, said buffer member having a recess formed therein, a female snap fastener member secured in said recess, said female member having a spring for engaging in said groove whereby said buifer member is removably held in said socket.

In testimony whereof I have hereunto subscribed by name at Chicago, Cook County,

Illinois.
