DOORCHECK Filed Oct. 3l. 1929 ATTORNEYS.

Patented July 26, 1932 UNITED STATES PATENT oFFlcE- ISAAC W. ROBERTSON, OF AKRON, OHIO, ASSIGNOR TO THE FIBE'STON'E TIRE & RUBBER COMPANY, F AKRON, OHIO, A. CORPORATION 0F OHIO DOORCHECK Application led October' 31, 1929. Serial No. 403,747.

This invention relates'to door checks and more particularly to resilient door checks for automobiles or the like. l

It is an object of the invention to provide a new and improved form of door vcheck to re- -siliently limit the extent ofopening movement of the door.

Again, it is an object of the invention to provide a strong, inexpensive door check 111 which a resilient cushion silently absorbs the shock of stopping the door at the end of its opening movement.

The above and other objects of the invention are attained by the door check illustrated in the accompanying drawing and described below, it being understood that the invention is not limited in ap lication to the specific form thereof descri ed and shown.

In the drawing,

Figure 1 is a sectional -view of a door and door jambequipped with a door check, embodying the invention wherein the check is mounted in the door. A

Figure 2 is a view similar to Figure 1, only vthe check is mounted in the door j amb.

Figure 3 is a. sectional view taken on line 3 3 of Figure 1.

Figure 4 is a sectional view on line 4?-4: of Figure 3. s

In Figure 1 of the drawing, the numeral 10 designates a hollow door, comprising a frame 10al and side plates 10b, hinged as at 11 to a door'jamb 12.

A plate 13 attached by screws 14 to the door j'mnb 12' pivotally supports a bar 1,5 which may be curved as shown to assist in allowing the door to open and shut throughout a greater angle. The bar 15 extends through a'slot 16 in the frame 10a of the door, and also through a rubber cushion 17 fixed to the inside of the frame 10 by suitable means such as screws 18. In the preferred form the e cushion 17, as illustrated in Figures 3 and 4,

includes a soft rubber body, a iange of reinforced rubber indicated at 11W/and an embedded metal washer 17h. At the-end of the bar 15 is a pin-19 which as shown in the dotted lines is adapted to engage with the washer 17 b of the cushion 17 to limit the out- 50 ward movement'of the door.

The form of the invention shown in Figure 2 is exactlythe reverse of that shown iny Figure 1, in that the check slides in the door ja1nb,whereas in Figure 1 it slides in the door. The plate 13 is applied to the door, the bar 15 extending through a suitable slot 16 in the door j amb. It will thus be seen that the door check can be applied to a door and jamb in two ways to meet varying constructions thereof.

In operation the cushion 17 serves as a guide for the bar 15, as well as a resilient sto for the bar-carried pin 19.

While the door check embodying the invention is particularly adaptable to automobile doors, it will be obvious that it can be employedin many other relations. Morev over, the exact form of the door check described and shown is to be taken in an illustrative and not a limiting sense, accordingly various modifications of the invention can be resorted to without departing fromthe spirit of the invention or the scope of the appended claims.

What is claimed lis:

5 1. In a door check, a door jamb member, a 7

4door member hinged thereto, resilient cushion means ixed in one of said members, l a bar pivotally connected to the other of said members, said bar extending through registered slots in said first member and in said resilient cushion means, and a stop on the free end of said bar engageable with said resilient cushion means to limit the opening movement of the door with a cushioning action.

2. In a door check for cooperation with a door j amb member, and a door member hinged thereto, a resilient cushion comprising a soft rubber body, a flange on said body for attaching the same to one of said members, said resilient cushion having an opening therethrough, a bar pivotally connected to the other of said members, said bar extending through and being slidably supported by the opening in said cushion, and means on said bar for abutment against said resilient cush- .ion to limit the movement of said bar through door j amb member and a door member hinged thereto, a hinge plate for attachment to one of said members, a bar pivotally connected to said hinge plate, resilient cushion means @comprising a soft rubber body, an embedded metal face, and a flange for attachment to the other of said members, said cushion means .having a slot therethrough, said bar being freely sldable through the slotvin said cush- 10 ion means, and a stop on the free end of said bar adapted to engage with the metal face of said resilient cushion means to limit the opening movement of the door.

ISAAOW. ROBERTSON.
