J. N. STONG. GRAVITATING DOOR CLOSER.
No. 448,656. Patented Mar. 17, 1891.
Mrs STATES JOHN N. STONG, OF WOODBRIDGE, CANADA.
GRAVFI'ATING DOOR-CLOSER.
SPECIFICATION forming part of Letters Patent No. 448,556, dated March 17, 1891. Application filed December 11 1890. Serial No. 374,336. (No model.)
To (tZZ whom it may concern/.-
Be it known that I, JOHN NOAH STONG, farmer, of the village of \Voodbridge, in the county of York, in the Province of Ontario, Canada, have invented a certain newand Improved Device for Closing a Door, of which the following is a specification.
The object of the invention is to design a simple device easily attached to any door or gate and which when applied will operate with ease and certainty; and it consists, essentially, of two bars connected together by a kuifejoint, the end of one bar fitting into a socket fixed to the door or gate and the end of the other bar fitting into a socket pivoted in a bracket connected to the doorj am b, substantially as hereinafter more particularly explained, and then definitely claimed.
Figure 1 is a perspective view showing the application of my device to a door. Fig. 2 is an enlarged detail of the operating -bars hinged together. Fig. 3 is an enlarged detail of the bracket. Fig. 4 is an enlarged detail of the socket. Fig. 5 is a plan of the joint.
In the drawings,like letters of refcrenceindicate corresponding parts in the different figures.
A and B are two bars connected together by the pin O, and shaped, as indicated in Fig. 2, so as to form what is commonly known as a knife-joint, the said joint being set so that end pressure against the bars A and B will cause the said joint to operate.
D is a weightsupported by the pin O and having a vertical pin E extending from it, and on which an additional weight may read ily be placed.
F is a socket fixed to the door G and designed to receive the end of the bar A, as indicated in Fig. l.
H is a bracket fixed to the door-jamb I and having a socket J pivoted on its end, as clearly shown in Fig. This socket is do 13, as
signed to receive the end of the bar shown in Fig. 1.
The weight D is intended to be heavy enough to hold the bars A and B in the posi tion indicated in Fig. 1, in which position the door is held closed, as shown. hen the door G is open, the end pressure against the bars A and B causes the joint to fold upwardly, and simultaneously the socket J revolves on its pivot, thus permitting the free opening of the door. When the openingpressure is removed from the door, the weight D forces down the jointed ends of the bars A B, thus causing the door to swing back on its hinges and close.
It will be observed that the bottom end of the socket J is beveled and that it rests upon a correspondinglybeveled surface formed around its pivot on the bracket H. These beveled surfaces are arranged so that the socket J will run, as it were, downhill-dun ing the closing of the door, and thus render surfaces perfectly horizontal.
I do not confine myself to the style of weight shown in the drawings, as this may be altered without in any way affecting the principle of the invention; nor do I limit myself to any particular kind or material, shape, or proportions of the various parts of my de vice.
Vhat I claim as my invention is- 1. Two bars A B, jointed together, the end of one end bar fitting into a socket F, fixed to a door or gate and the end of the other bar fitted into a socket J, pivoted in the end of a bracket H, fixed to the door-jamb in line with the socket F, in combination with a weight applied to the said bar or bars, substantially as and for the purpose specified.
2. Two bars jointed together. the end of one bar fitting into a socket fixed to a door or gate and the end of the other bar fitted into a socket pivoted on the end of a bracket fixed to the door-jamb, the bottom of the said socket being beveled and designed to rest upon a correspondingly beveled surface formed around its pivot in the said bracket, in combination with a weight applied to the said bar or bars, substantially as and for the purpose specified.
