DOOR-STOP.

Application filed June 19, 1916.

To all whom it may concern:

Be it known that I, FRANK H. CHASE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Door-Stops, of which the following is a specification.

This invention relates to doorstops of the general type adapted to be mounted on a baseboard or in any other suitable position back of a swinging door and against which the door abuts when fully opened, the stop serving to limit the opening movement of the door and prevent the doorknob from contacting with and marring the wall.

Doorstops employed prior to my present invention have been, so far as I am aware, made of either wood or cast metal in the form of an elongated block tipped with rubber. Blocks of this character however, being entirely rigid, are easily knocked off from their point of attachment and in use they arefrequently loosened or entirely displaced from the baseboard by accidental blows of a broom or carpet sweeper, or by being hit by furniture or boxes, particularly at moving time.

One of the primary objects of my present invention is to provide a doorstop which will be flexible in character, so that it will yield laterally when struck by moving articles without being injured or dislodged and will subsequently resume its normal position.

Another object of my invention is to provide a doorstop which will be simple in construction, cheap to manufacture, attractive in appearance and durable in use.

For the purpose of facilitating an under standing of my invention 1 have illustrated one preferred embodiment thereof on the accompanying drawings, from an inspection of which, when considered in connection with the following description, the invention should be readily understood. Referring to the drawings Figure 1 is a side elevation partially in section of a doorstep embodying my invention;

Fig. 2 is a sectional view on the line 22 of Fig. 1.

Fig. 3 is a fragmentary side view of the device partly in section showing a modification.

The doorstep, as illustrated on the drawings, comprises a circular base 8, preferably Specificati an of Letters Patent.

cast, stamped or pressed from suitable metal and provided with a central outwardly projecting hollow stud or boss 4:. The shank 5 of the stop consists of a closely wound helical coil spring, one end of which fits snugly within the boss -1 to which it may be anchored by solder or in any other suitable manner if found desirable. The outer end of the shank is provided with a tip (3 of relatively soft material, preferably rubber, which will receive the impact of a door without marring the finish on the door. This tip, as shown, is made in the form of a cap adapted to fit over the outer end of the shank, but obviously it might be shaped to fit inside the shank if preferred, as shown at 6 in Fig. 3 of the drawing, the only requisite being that the tip project beyond the metal shank to cushion the impact of the door and prevent injury to its finish.

The base 8 is provided with a plurality of apertures 7 adapted to receive wooden screws 8, by means of which the base is secured in the proper location to a baseboard 9, or other conveniently located means of support. A fragmentary portion of a door in cooperative relation to the stop is indicated by reference character 10.

The stop when mounted normally assumes the position shown in full lines in Fig. 1 so that when the door 10 is swung open into contact with the stop the impact of the door will be received along the longitudinal axis of the shank 5, and except for the resiliency of the soft tip 6 a substantially rigid abutment will be presented against which the door will strike. The opening movement of the door is thereby terminated before the doorknob can contact with and. mar the wall. If the stop should be struck a lateral blow from any direction, instead of being torn from its support, as customarily happens with rigid stops now in use, the flexible shank will yield laterally under the impact of the blow without injury to the stop or its means of attachment. A distorted position of the stop is shown in dotted lines in Fig. 1, but the character of the flexible shank is such that the tip may be bent substantially back without injuring the stop in the least, and as soon as the application of force is withdrawn the shank will spring back and the stop will resume its normal position, shown in full lines in Fig. 1.

It will thus be obvious that I have provided a door-stop which is not subject to injury or dislocation from its point of support when subjected to lateral forces or blows from any direction, but on the contrary, the stop will yield away from the force applied and immediately resume its normal position when the force is withdrawn. Furthermore, the stop normally presents a substantially rigid abutment against which the door may strike and the stop as designed is not only durable in construction but also presents a more pleasing and attractive appearance than the cumbersome wood or metal stops heretofore employed.

I claim:

1. A doorstop comprising a shank provided at one end with an impact head and at its opposite endwith means for rigidly atwhich is rigid as to endwise impactand elas-- tically yieldable as to sidewise blows, means on one end of the shank for rigidly attaching the same to a support, and'an impact headof yieldable material inserted in the open outer end of the shank and projecting exteriorly thereof.
