Door Check (No. Model.)
.0 ON, 6 3 2 o UNITED STATES PATENT OFFICE.
FRANCIS V. PHILLIPS, OF CHICAGO, ILLINOIS, ASSIGNOR TO GEORGE H. DAYTON, OF SAME PLACE.
DOOR-CHECK.
SPECIFICATION formingpart of Letters Patent No. 2136,910, dated January 25, 1881.
I Application filed April 16, 1880. (No model.)
To all whom it may concern:
Be it known that I, FRANCIS V. PHILLIPS, of Chicago, State of Illinois, have invented certain new and useful Improvements in Door- Fasts; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanyin g drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to the class of doorfasts intended to hold a door when partially opened. It has for its object, first, to positively hold the door from closing, as well as from opening farther when thus partially opened; second, to automatically fasten the door closed when pushed suddenly shut; and, third, to operate as a fastening to the closed door.
To these ends it consists in the several features of construction herein after fully set forth, and pointed out in the claims.
Figure 1 of the accompanying drawings shows my device operating as a fastening for the closed door. Fig. 2 illustrates the same in its automatic action as a catch when the door is pushed shut. Fig. 3 shows its operation as a fastening to hold the door ajar. Fig. 4 is a sectional view of the door-plate, showing the construction and manner of holding the turn-pin. Fig. 5 shows,in elevation, a device alternative to the turn-pin, and equivalent thereto, as afastening for the link-bar; and Fig. 6 is a vertical section of the samethrough the line 00 a: of Fig. 5.
A represents a link-bar of suitable length, pivoted to the jamb J by means of the eye B. O is a plate secured to the inner face of the door It near its free edge and opposite the eye B. Said plate has the elevated T-shaped projection D, over which the link A runs, and which serves as a detent to limit the opening of the door. As shown in Figs. 1, 2, 3-, and 4, it also has the turn-pin E, over which, when turned horizontally,the link may pass, and which, when turned vertically over the link, serves to hold the latter down, and thus fastens the door closed. The link A has an enlargement, F, of its slot G, near the jamb end, which enables the same to be slipped over or disengaged from the projection D on the plate 0. It also serves as a means of automatically fastening the door so nearly shut as to leave no opening between the door and jamb when the door is suddenly closed. This it does by allowing the link to drop so that the shoulder a of the link engages with the arm 11 of the projection D. The slot G is also provided with an enlargement, H, at its outer or free end, by which the link-bar is permitted to drop when the door is opened to the full length of the link, and, by the engagement of the shoulder 0 of said enlargement with the arm I), to hold the door open. By means of this provision the door may be safely left and will remain ajar for the purpose of ventilation.
This device may obviously be applied to the ordinary form of webbed link-bar in common use, in which opposite grooves engage with the proximate ends of an open loop secured to the door. The enlargement of the grooves to form shoulders corresponding with the shoulder c, to engage with the said proximate ends of the open loop, would be an embodiment of this invention in such solid bar.
The turn-pin E is shown secured to the plate 0 by a novel construction of the parts, with the object both of economy and strengththat is to say, the turn-pin is cast with the flange e on the end of the shank, and a corresponding recess, 11, is cast in the under face of the plate 0, to receive the flange. By means of the slot f in the plate the turn-pin is readily admitted to position when the plate is to be secured to the door, and is securely held by the plate. As the parts require no careful fitting and no riveting, this construction is cheap, and, by reason of the broad flange or head 0, the turn-pin, as a fastening, is very strong.
Instead of the turn-pin E arigid catch may be employed, behind which the link-bar A may be dropped, operating like the catch of an oldfashioned door-latch. Such a catch is shown at E in Figs. 5 and 6. The plate 0 in these figures is provided with two catches, for the purpose of fitting it to both right and left hand doors. A central catch may be used in the locality of the turn-pin; but such construction requires an objectionable width of slot in the bar or link A.
Having thus described my invention, I claim- 1. The link-bar A, to bepivoted tothejnmb, provided with the open slot G, having, the en- 5 largement F near the jainb end of the bar, in
combination with the projection l), to be secured to the door, substantially as described. 2. The link-bar A, pivoted to the jainb by means of a staple, B, provided with the slot 10 G, having the enlargement H at its free end, combined with the T-headed detent I), mounted at the end of a curved arm, b, to be secured to the door, substantially as described.
3. The link A, tobe pivoted to the jamb, pro- 15 vided with the slotGandenlargement F at one end thereof, combined with the projection I) and M. E. DAYTON, JESSE Cox, Jr.
