' present invention relates to an improvement in anti-rattle devices for vehicular doors, more especially automobile doors T and has for its principal object, the provision of an improved form of dovetail gripping members whereby greater resiliency is accomplished between these members, thereby improving their'anti-rattle action, increasmg the silencing action, absorbingthe'shock of 1 slamming the door and when opening the door'to provide an addedautomatic impetus to the door opening action.

A further object is'toprovidean active structure that may be'fitted into standard metal casingsof such devices as already applied, as a substitute for: original installations', Wheredesired. 1 1 These and other capabilities will be apprehended as the description proceeds and it is obvious that modifications may be made in the structure herein without departing from the spirit hereof or the scopeof the claims. "In the drawing: v a I Fig. 1 is a plan view of a casing showing the device appliedtherein; Fig. 2 isafront view of Fig. 1'; Fig. 3 is a rear view thereof; l 1

Fig. 13 is an assembled compressible bufier showing a modified arrangement; Fig. 14 is a perspective view ot'the top cover of the casing; and,

Fig. 15 is a perspective view of the bottom thereof. I g "i a Throughout the views Figs. 1 m5, inclu sive, and in Figs. 14 and 15, I have shown a standard outer metal casing for enclosing the operative buffer parts which latter 'jare'ol novel construction,

Anysuitable housing may be used. In the present housing construction, the structure comprises atop and'lower casing, 1 and'2, re-. spectively. The upper portion 1 has a dovetail admitting opening 3 which extends down 55 j thefront face of the angularportion v4 and terminates at the flange '5, Fig. 14. 7 ;The bottom casing 2, shown in perspective view, Fig. 15, has a box-like portion 6 formed by bending up portions of the bottom plate 50 9 to form the ends 78, and bending up one 7 side 9 from the bottom plate 9 This forms the enclosure for the operative "buffer por tions, when the portion 2' is assembled to portion 1 to form a casing. Flanges 10' 11 ex{ '65 I tend from the sides 7 8, and screw holes {12 in said flanges register with screw holes 13 1 A in the opposite ends ot the portion 1, when r 7 portion 1 is placed thereover,so'thatf four screws: join-the two casing iportions'tofthe door "j amb of the body of avehi la otshown, in the usual manner. e i

1 ASQthlIS briefly "described, the casing is of well known make,though any suitably designed casing can be used.

The novelty liesin thebufier members gen- 'erally denoted by-1415,Figs. 5-6. I As there shown the bufiersare mounted inthe box like part ofpo'rtion 2, formed'by the sides 7 S,"end plate 9 and b'ottom 9', so that the two of said bufiers lie pivotally opposed .to each other, as in Fig. 5, and are supported in floating, resilient noneoperative outward po sition biy'a curved flat spring'16, the ends of which rest upon theside' 9 of the box. Be-

tween the buffers 1415 is a space 17 into which the dove-tailof-the door,jindicated in Fig. 6 byfdottedlines, enters, when the door is closed; This space between the buffers, and

a portion of thebu'fiers is exposed by the cut 9 out 3, of the casing portion l, as in Fig. 1.

The buffers" are each provided, at their lower inside faces, at thebottom of the space 17, Figs. 5-6, withan'extensi0n18', these, in

efiectcreating a joint -stop,against which the nose 19 of thedovetail, shown dotted Fig. 6, contacts, thus, causing the buffers 14-15 to rock backwardly from position shown in Fig. 5, to that showninFi'g. 6.

Simultaneously as the blocks rock to their 9 rear faces upon the cam points 20, against the walls 7 8, owing to their cam like formation, they squeeze the dovetail between them. This squeezing action, is, naturally, confined between and taken up by the side plates or walls 78, and thus the action upon the dovetail partakesof toggleactiomin principle. Thus the dovetailisasnugly held inifirmriresi'lient V 7 Upon compressing action by the dovetail Combined with the opposedcainmingaction of the buffers, and as this final double compression takes place at about theline"AB, Fig. 6 all such compression forces are kept well within the confines of the walls of the lower'casing2. e r

. Thereis, therefore, no 'tendencyzofthecompressive forcesbetween the dovetail the buffer and walls -"('-8, Fig. 6, to be exertedexternal to the housing 2,.and thus wear on the strikers or strike plates vof-the door lock is obviated.

Further, due to the proportions of'the' bufferz membenzas in Fig. 16, ;the dimension C, when the. buffers (arein non-operative posi- I tion-readyto receive theidovetail, as Fig. '5, is; shorter: :than i the :dimension D, Fig. 13.

Tlherefore,- when: the dovetail-1 engages and forces theebufferi bloeksto rockbackwardl'y, theggreateri'dimensions of the lower portions of the .blocks squeez'e the dovetail between the curved faces-122 of theblocks, as; previously described with aitoggle like. action, the-forces of which .are: confined entirelylwithinthe confinesof the-wallsofthe surroundingcasing.

An alternative form of compressible buffer structure is shown in Fig. 13, wherein the spaced blocks a and b are made of solid metal, with blind holes drilled therein, and coiled springs 25 and.-25; assembled-in the blind holes. A guide pinl26 slidablymountedbetween the blocks keeps them in registry. This structure is simple andoperates in a practical manner.- i

Thecurved support spring 16 has only a light 'duty't'o perform, as it is utilized to merely -lreepntheebufier blocks in the outer normal receptive position for the dovetail, when .the:dooris' open, thus to insurethat the :blocks; will be ready: at all times, when thedoor is open,to compressively absorb doorxclosing shocks and thereafter to grip; the dovetail toggle wise, tOT hold it, with its-nappurtenant door in firmlyvresilient antierattle position. 7

.After 'theodovetaillhas been seated, as in Fig. '6, the door havingbeen closed, the act of opening the door is accentuated bythe herein .described bnfi'er structure.
