DOOR SPRING.

Patented June 121860..

JACOB POST, OF NEWARK, NEW JERSEY.

DOOR-SPRING.

Specification of Letters Patent No. 28,689, dated June 12, 1860.

To all whom it may concern:

Be it known that I, JACOB Pos'r, of Newark, in the county of Essex and State of New Jersey, have invented a new and Improved Door-Spring; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 represents the door spring, showing the construction of the same, and the position of the parts when the door would be in a closed state. Fig. 2 is a perspective view of the spring, showing it as applied to a door and door frame, with the door in red lines, represented in a partially open state. A portion of one ear is broken off to show the segmental rack and rack bar for operating the spring.

Similar letters of reference indicate corresponding parts in both figures.

To enable those skilled in the art to fully understand my invention, I will proceed to describe its construction, and operation.

In the drawings, A, represents a fiat plate of a suitable strength made of cast or wrought metal which is to be screwed fast to the lintel of a door frame, to a gate post or to any other suitable place where it will be required, and on the face of this plate A, is made to slide a peculiar shaped rack plate B, from the small end of which proceeds out a round rod D, the end of which passes through a fixed bracket piece a, that is formed on or near the end of plate A.

E, is a helical spring that is passed over the rod D, which abuts against the end of the rack enlargement B, and against the piece a. The rack B, is by this means forcibly kept in the position on plate A, represented by Fig. 1, in black lines.

C, C, are two ears projecting out a suitable distance from each side of plate A, and either riveted to said plate or cast with it, and between these cars C, C, the enlargement B, is held so as to be confined a ainst any lateral movement, but to have a ongitudinal movement that is given to it by the joint action of the spring E, in recoiling, and a lever arm G, havmg on its end a toothed segment H, the teeth of which engage with the teeth of the rack B, as clearly shown in the perspective view, (Fig. 2) the lever G being pivoted at 0, between the ends of the ears C, C.

J is an arm projecting out from the toothed end of lever Gr, nearly at right angles to this lever, having on its end a friction roller. (Z, c is a projection of the enlargement B, that acts upon the arm J, after the teeth on this enlargement B, ceases to act in closing the door, and previous to these teeth in opening the door. The toothed racks B, H, are constructed and operated very much like two eccentrics, the power gradually diminishing as the lever is opened, and increasing, as the door is brought to a closed state until the arm J, is brought into action by coming in contact with projection 6, when the spring will act with its greatest force on the lever G, (door) in consequence of the increased distance from the fulcrum of the lever G, to the power exerted on the arm J, the door will thus be kept closely shut.

The red lines of Fig. 2 represent a portion of the door frame and door with a grooved roller projecting from the top of the door into the groove of which plays the lever G. The attachment of this lever G, with a door or gate may be made in many different ways, but to this I do not wish to lay claim.

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

The combination with the sliding spring rod D, and lever G, of the stepped or inclined rack B, projection 6, arm J, and segment H, in the manner and for the purpose herein shown and described.

JACOB POST.
