DAVID A. HARRISON, OF ROXBURY, MASSACHUSETTS, ASSIGNOR TO D. HARRISON '00., INCL, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS.
ADJUSTABLE BUFFER.
Application filed January 29, 1924.
To all whom it may concern:
Be it known that I, DAVID A. HARRISON, acitizen of the United States, residing at Roxbury, in the county of Sufiolk and the State of Massachusetts, have invented cer tain new and useful Adjust-able Buffers, of which the following is a specification.
This invention relates to buffers for doors and particularly for doors of automobiles and has for its main object the provision of means whereby such buffers-may be adjusted to compensate for wear to thereby prevent liable in operation.
The above and other objects of the inven tion which might hereinafter appear are at- L tained by constructing the bufiers in the Fig. 3 is a sectional view on the line 33 of Fig. 1;
Fig. L is a sectional view on the line 44 of Fig. 1;
Fig. 5 is a sectional View on the line 5-5 of Fig. 2;
Fig. 6 is a sectional View on the line 66 of Fig. 5;
Fig. 7 is a perspective view of the horizontally movable member for moving the buffer element; and
Fig. 8 is a perspective view of the member which is moved by the adjusting screw for moving the member shown by Fig. 7.
Referring to the drawings in detail, the reference character 10 represents the buffer Serial No. 689,255.
and has one of its sides provided with the cutaway portion 1l, as shown more clearly :by Fig. From an inspection of the drawings it will be seen that this casing 10 is of rectangular box like construction having a closed end 12 and an open end '11 shown more clearly by Fig.6. The inner side 140i the casing 10 is provided with openings 15 and 16 for the passage of screws 17 whereby the casing may be secured to the door j amb 18. Slidable within the casing-1O is mounted the bufier element 19 provided with a lip element 20 which overlies the outer side 21 of the casing 10. Connecting the main portion of the bufier element 19 and'the lip portion is an intermediate portion 22 of approximately the thickness of the outer side 21 of the casing 10 and of the configuration'of the cutout portion 11, audit will be understood that this intermediate portion 22 will be received within the cutout portion 11. The buifer element 19, its lip 20, and the intermediate portion will preferably be made" of rubber, but may be formed of'any suitable material which has cushioning-proberties.
It. will be understood that the buffer element 19 has a snug sliding fit within the casing 10. As shown by Fig. 1, the door 23 abuts the end of the buffereleinent 19, and it will be understood that while I have shown the buffer secured to the door-jamb of an automobile body so as to" bereceived within a recess in the door when closedfth e buffer may instead be attached to the door and be received within a recess in the door frame, and in this respect theiinterchangeabilityof the buffer will be appreciated withouta detailed illustration.
To enable the quick and convenient adjustment of the buffer block 19 as the same becomes worn or when loose play between the door and the amb occurs for any other reason, there are provided the buffer block adjusting means which will be described presently. This means for adjusting the buffer block comprises the members 23 and 24 and the adjusting screw 25. The members 23 and 24 are positioned within the casing 10, as shown by Fig. 6, between the buffer block 19 and the closed end 12 of the casing, and it will be seen that these members are substantially triangular in cross section. The member 23, which for the sake of convenience may be designated as a cam member, is provided with a screw threaded aperture 26 which receives the adjusting screw 25, the latter passing therethrough and being longitudinally immovable with respect to the casing 10 so that rotation of this screw will cause linear movement of the cam 23. One end of the adjusting screw 25 has a slotted head 27, and the other end of the screw has an upset portion 28 whereby the screw is held in fixed longitudinal position in the casing 1.0. It should be noted that the screw is arranged so that when it is turned clockwise the cam member 23 moves toward the outer side 21 of the casing 10 and that the reaction between the casing and the screw is taken up between the head 27 and the outer side 21, and it will be understood that this arrangement is made so as to relieve the weaker end 28, which by reason of quantity production, cannot for commercial reasons be turned out in condition good enough to stand the stress. The member 24, which may be called a follower as distinguished from the cam member 23, is arranged for cooperation with the member 23 so that as this latter member is moved toward the outer side of the casing 10, the follower 24 will be moved toward the open end 13 of the casing, as is readily apparent.
The operation of the buffer will be easily understood. lVhen first attached to the jamb, the block 19 will project sufficiently so that the door firmly abuts it and is thus prevented from rattling. \Vhen the projecting portion of the block becomes worn from continued use or when loose play occurs between the door and the jamb for any other reason, the screw 25 may be turned so that the cam 24 moves the follower to move the block 19 outwardly from the casing 10 until the door again firmly abuts the end of the block. Thus a very rapid and convenient adjustment of the buffer may be made without removing the casing from the door frame or the door.
While I have shown the preferred embodiment of the invention, it will be understood that certain changes in the construction and arrangement of parts may be made and will suggest themselves, especially in view of this disclosure, but it is to be understood that all such changes are to be considered as part of the invention as defined by the appended claims.
Having thus described my invention, What I claim and desire to secure by Letters Patent of the United States is:
1. A buffer device for automobile doors comprising a hollow casing, a buffer block slidably mounted within said casing and having a portion extending outwardly therefrom, and means for adjusting said buffer block with relation to said casing comprising a screw threaded cam member, a follower member, and an adjusting screw, said adjusting screw passing through said cam member in actuating engagement therewith and having its one end bearing on one side of the casing and its other end upset against the other side of the casing whereby said screw is held in fixed longitudinal position in said casing.
2. A buffer device for automobile doors comprising a hollow casing, a buffer block slidably mounted within said casing and having a portion extending outwardly therefrom, and means for adjusting said buffer block with relation to said casing comprising a screw threaded cam member, a follower member, and a longitudinally fixed adjusting screw passing through said cam member in actuating engagement therewith.
3. A buffer device comprising a hollow casing having a recess in one of its sides and a buffer block slidably positioned within said casing, said buffer block having a lip portion projecting rearwardly therefrom and a portion intermediate the lip portion and the buffer block adapted to be received within the said recess in the side of the casing.
In testimony whereof, I hereunto aflix my signature.
DAVID A. HARRISON.
