SPECIFICATION formingpart of Letters Patent No. 696,116, dated March 25, 1902.
Application nea June 11. 1897.
.'l'o all whom it' may concern:
Be it known that I, WARREN II. TAYLOR, A
Io taining the springs for closing the door, and
in the present case I locate in the springchamber a number or series of spiral springs, which through suitable power-distributing means are compressed at different speeds in 15 dierent positionsY of the opening movement of the door, so as they can act to give the required ease to start and a greater power to close the door. The power-distributing means consists of. an eccentrically-arranged 2o gear carried on theshaft or spindle connected with the door and piston in the pistonchamber and a peculiarly curvilinear or ogee shaped rack formed on a right-angle link connected with a sliding head or carrier against The gear is so arranged with relation to the rack that the rack will act upon the longest radius of the gear When the door is closed, thus insuring the maximum force of the springs in clos-A It will be seen that by this construction the movement of the springs as the door is closing or just as it is opened is fastest and their power greatest, whereas as the door 'gets more and more open the speed of the springs becomes less and their power also less. The usual method has been to vary the piston speed under these conditions, without providing any means for varying the actual movement or by this construction the movement of the springs just as the door is closing or just as it is opened is fastest and their power greatest, whereas as the door gets more and more open the-1novement of the springs becomes less and their power also less. The usual method has been to vary the piston speed under these conditions, without providing any means for varying the actual movement or 5o efficiency of the spring.V It is obvious that in It will be seen that-Y Serial No. 640,379. (No model.)
place of a gear there might be used an eccentric-toothed cam or other equivalent.
My invention also consists of certain other details of construction, that will be hereinafter more fully described, and specifically pointed out in the claims.
In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which- Figure l is a perspective view; Fig. 2, a vertical longitudinal section; Fig. 3, a horizontal section; Fig. 4, a vertical transverse section; and Figs. 5, 6, and 7, respectively, a front, side, and top view of the fasteningplate.
In the said drawings, l represents the casing of the door-check, which is formed with the piston-chamber 2 and separate springchamber 3, both of which may be arranged with relation to each other as desired. The casing is adapted to be secured to the doorframe, as is usual, and to easily attach the same I provide the inclined and undercut projections 4 on each side the casing, between which the beveled edges 5 of the wedgeshaped part 5 Vof the plate 6 fit. This plate is preferably of the form shown in Figs. 5, 6,
and 7, which is such as to enable the casingv manner and is provided with the piston 7, of
any desired construction, and it is connected with the vertical shaft or spindle S, which passes through the chamber 3 and has the usual connection 9 with the door. The shaft 8 is provided with the eccentrically-arranged gear 10 in engagement with a rack l1, of curvilinear or ogee form, which is formed on a right-angle link 11a, connected at one end with the sliding head or carrier 12 and provided at its other end with a roller 13, which bears against one side of the chamber to reduce the friction at that point when the rack is moved.
The sliding head or carrier l2 is provided with the rods 14, the vfree ends of which t in the open tubes l5, carried by the head 16 at the other end of the chamber, which is adjustably held by the screw 17. 1S represents spiral springs surrounding the tubes and rods and bearing against the heads, and they are compressed when the door is opened and serve to operate to close the door when it is released.
It will be observedV from thc drawings that the rack 1l is so arranged with relation to the eccentric gear that the springs will cause the rack to operate on the gearat its shortest diameter when the door is to be closed, thus giving the door the required easy start, and when the door is about closed the rack will then act upon the longest diameter, using the maximum power of the springs, thereby giving a strong movement to effect ually close the door and keep it closed.
The operation of the rack will be readily understood. As the door is opened the spindle or shaft is turned to move the piston back in the pistonchamber and compress the spring. As the door is released the springs act upon the rack and eccentric gear in the manner above set forth lo. close the door, the piston serving to prevent a too-rapid closing ot' the door.
It is obvious that in place of a gear there might be 'used an eccentric-toothed cam or other equivalent.
Having thus described my invention, the
following is what I claim as new therein and desire to secure by Letters Patent:
1. In a door-check provided with spring and piston chambers, the combination of a sliding head or carrier within said springchamber, of springs also Within said springchamber and bearing against said head or carrier, of an ogee-shaped rack pivoted to said head or carrier,an eccentrically-arranged gear engaging said rack, and a shaft or spindle connected to the piston in the pistonchamber and to the door, said gear carried by said shaft or spindle.
2. In a door-check provided with spring and piston chambers, the combination of a. sliding head or carrier within said spring-v chamber, of springs also within said springchamber, and bearing against said head, o1' carrier, of an ogee-shaped rack pivoted at one end to said head or carrier, of a frictionroller carried by the free end of said rack, of a shaft o1' spindle connected at one end to the piston in said piston-chamber and at the other end to the door, and an eccentrically-arranged gear carried by said shaft or spindle and adapted to engage said rack.
\VARREN II. TAYLOR.
