TERTULLUS S. DIBLIN, OF TRENTON, NEW JERSEY.

DOOR-CHECK.

SPECIFICATION forming part of Letters Patent No. 507,889, dated October 31, 1893.

Application filed August 31, 1893. Serial No. 484,430- (No model.)

To all whom it may concern:

Be it known that I, TERTULLUS S. DIBLIN, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Door-Checks, of which the following is a specification.

This invention relates to door checks, and its novelty will be fully understood-from the following description and claim when taken in connection with the annexed drawings; and the object of the invention is to provide a door v check of simple, durable and inexpensive construction, to effect holding a door open or closed or partly so, through the friction of an elastic cushion or rubber ball in contactwith the floor of a dwelling houe,or other build- 1ng.

Theinvention consists in the novel arrangement and construction of parts, as will be hereinafter more fully described and set up in the claim.

In the accompanying drawings forming part of this application: Figure 1 is a perspective view of a portion ofa building showing a door provided with my improved check. Fig. 2 is an enlarged front view of the door check. Fig. 3 is a side elevation thereof. Fig. 4 is a sectional view taken on the plane indicated by the dotted line 0ca3 in Fig. 2.

The same letters of reference denote the same parts throughout the several figures.

To the doorA, is secured by screws a, the bracket 13, having two right angle loop projections C, and D, respectively, formed integral with the bracket B. The loop projection G, has teeth 0, formed upon its end, upon the inside. Through these loops 0, and D, extends a slidable lever E. To the lower end of this lever E, is secured a cushion or rubber bail F, by means of a pin f, passing'part way or entirely through the said cushion or ball, and through the said end of the lever E. A rack or teeth e, is formed upon the lever E, above its central portion, which engages the teeth c, of the loop projection 0. Midway between the cushion F, and the lower ends of the teeth e, is secured to the back of the lever E, the plate spring G, for keeping the two sets of teeth engaged, except when the lever E, is being raised or lowered.

The upper end of the lever E, is curled both towards the front and back, from the central vertical plane of said lever, to form thumb and finger handles H, and '11, respectively, and when this handle is pushed by the thumb it causes the said sets of teeth 0, and

e, to disengage, leaving the lever E, free to be raised or lowered by the fingers of the same hand of which the thumb upon the said han die is a member;

It is believed the principle of operation of this check is so well known that it will not be set out further herein. The connection between the lever and the cushion is of great advantage, owing to its simplicity and effectiveness. The construction of the hand portion of the lever enables it to be operated with one hand with the greatest of ease and accuracy.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a door check, the bracket, the toothed loop formed integral with the bracket, the slidable lever having teeth, the plate spring bearing against the bracket and secured to the lever, and normally keeping the teeth of the lever engaged with the said toothed loop, the cushion ball, means forsecuringit to one end of the lever, and the thumb and finger handle formed upon the other end of the said lever, substantially as shown and described and for the purpose set forth.

In witness whereof I hereunto set my hand in the presence of two Witnesses.

TERTULLUS S. DIBLIN.

JOHN MATHESON, H. F. HILL.
