device is housed within the body or door of the car. a

Y The object of the invention is tO PIOYIdB a door stop, which is relatively inexpensive to manufacture, one which is strong and durable' and which is so constructed that any rattlebetween its parts and between it and the body or door is prevented.

A further object is to provide a member to cushion the outward swing of the door as it reaches its limit, the cushion being designed to prevent rattling of the retaining means, and in some instances to serve as the sole means for holding the adjustable abutment member in'place on the swinging arm.

With these and other objects in view as will appear from this disclosure, the invention resides in all the novel features of construction and combination of parts herein described and particularly pointed out in the appended claims.

In the drawing which forms a part of this specification, Fig. 1 is a top plan view of the door check in place in the body and door of an automobile, the last mentioned parts being shown in section; Fig. 2 is a sideelevation of the complete door stop; Fig; 3 is an enlarged fragmentary sectional detail view of the inner end of the arm, adjustable abutment member and cushion; Fig.4 is an end elevation of the device; Fig. 5 is an enlarged detail view similar to Fig. 3 showing a modified form where the cushion member alone serves as the retainer for the abutment member; Fig. 6 is an end elevation of the evice shown in Fig. 5; and Figs. 7 and 8 show another modification of retainer held in place by the resilient cushion.

In describing my invention reference is -made to the accompanying drawing wherein like'reference numerals designate like parts in the several views and wherein the reference numeral 10 designates generally the door check which comprises a racket member 11, swinging arm 12 and a stop or abutment assembly designated generally by the 59 reference numeral 13.

1929. Serial No. 377,092.

Thebracket 11, in the form illustrated, is made from sheet metal the ends of which are folded back on itself toward each other and then bent outwardly in parallel planes providing spaced ears 15 between which is pivotally secured by means of a rivet 16 one end of the swinging arm 12.

The arm 12 which is a thin fiat bar is bowed intermediate its ends in the plane of its width to permit the same to move freely in the body or door of the car when the door swings open. At its outer end the bar is provided at its opposite edges with pairs of notches 18 in which a bifurcated washer 19 is adapted to fit. A cup washer 20 provided in its bottom with a slot of a size to accommodate the bar 12 fits onto the-rod and about the washer 19 for holding it in the notches. At opposite sides the cup Washer 20 has integral fingers 21 which after it is slipped over the washer 19 are bent down over it to prevent separation of the two washers and any chance of the bifurcated washer 19 from becoming disengaged from the notches 18 in the bar 12. To prevent any rattle between the two washers a thin leather washer 22 is fitted in the bottom of the cup washer 20 against which the bifurcated washer 19 is clamped by the fingers 21.

snugly fitting on the bar 12 back of the stop or, abutment washers 19 and 20 is a non-metallic resilient cushion member 25, preferably of rubber or material having similar characteristics. The member 25 is cylindrical at i s inner end 26 and terminates at its outer end 27 in a frusto-conical flange flattened at opposite sides as at 28. The aperture in the member 25 through which the bar 12 extends is substantially the same shape as the bar so there is no rotation of the cushion member thereon and the flat sides 28 are parallel with the flat sides of the bar.

At its outer end the cushion member 25 has a recess 29 of sufficient diameter and depth to receive the washers 19 and 20 with a snug fit and at its outer edge it may be formed with an inwardly extending annular flange 30 which engages about the outer peripher of the washer 19. The cushion 25 when orced outwardly over the washers 19 and eliminates any possible chance for rattling of the metal pieces one on the other.

In Figs, 5 and-6 I have shown the cushion member with the aperture 29 of a size to receive only the bifurcated washer 19, the cushion member 25 alone serving to hold the washer in the notches 18 when engaged about it. The flange 30 prevents accidental displacement of the member 25 from the washer 19. In many cases this form of. abutment and cushion is sufficient and the cost of producing the door check is substantially decreased.

In Figs. 7 and 8 I have illustrated a somewhat modified form of abutment-wherein the bar 12 is provided with apertures in which the extension 36 of a semi-circular washer 37 fits. Back of this washer is a flat washer 38 provided with an opening conforming to the shape of the bar 12 so that a flat abutment of substantial'area is provided against which.

the resilient cushion member 25 abuts, the recess 29 receiving the washers 37 and 38. The cushion member. prevents the displacement of the holding washer 37, the lip 30 en-,

gaging over the same and prevents the cushion member from sliding away from'th'e washers when once properly pulled into place.

1' metal car body. A leather strip 43 provided with a slot 44 slightly larger than the arm 12 is secured to the mner face of the frame 42 providing a guide for the arm as the door opens and closes and a comparatively soft surface against which the rubber cushion member 25 may strike. It will be noted that the flange 27 on the cushion will prevent the end of the rod from contacting with the walls of the car body when the arm is vibrated back and forth due to the vibration of the car in travel.

The door check may of course be mounted on the frame and be housed in the door in substantially the same manner as shown. The bracket 11 may be secured on the outer face of either door or frame if desired. It is obvious that the device'may be mounted on cars having wooden stiles or door posts in the same manner.

in view at any time it-adds to the neatness and sim licity of thebody construction of the car in w 'ch it may be, installed.

Various changes in the specific construct1on' of the door check may, of course, be made without 'departingfrom the spirit of tile invention or the scope of the appended c aims.

Having thus described my invention, what- I claim 1s 1. A door-stop construction including a bar, a rubber cushion through which said bar extends, a member deta'chably secured to saidbar and having a bearing surface adapted to abut one end of said cushion, said cush- IOIl having a cavity formedtherein to receive said member, said cavity conforming in shape to said member and receiving the same snugly.

2. A door-stop construction including a bar, a rubber cushion through which said bar extends, a member detachably secured to said bar and having a bearing surface adapted to abut one end of said cushion, said cushion having a cavity formed therein to receive said member, said cavity conforming in shape to said member and receiving the same snugly,

and a laterally extendin flange formed onsaid cushion adjacent sai cavity.

In testimony whereof, I hereunto aflix my signature.

ALBERT C. EARHART.

The bracket 11 may be of any desired construction to permit the arm or bar 12 to pivot in the plane of its width whereby the greatest strength for the size of bar is obtained.

By making the door check with a flat swinging arm only a narrow slit need be provided in the door stile or pillar post; the cost of manufacturing is kept at a minimum since every part may be stamped from heavy sheet metal, no turnlng of parts threading or dressing being required.

he device is exceedingly strong and since only a small portion of the thin flat bar'12 is
