JACOB FOSTER, OF ALTOONA, PENNSYLVANIA.
TRANSOM LIFTER AND LOCK.
SPECIFICATION forming part of Letters Patent No. 681,207, dated August 27, 1901.
Application filed m 4, 1901.
.To all whom it may concern.-
Be it known that I, J ACOB Fos'rna, a citizen of the United States of America, residing at his Altoona, in the county of Blair and State of Pennsylvania, have invented certain new and useful Improvements in Transom Lifters and Locks; and I do declare the following to be a 1 full, clear, and exact description of the in yention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom- ,panying drawings, and to the letters and figl ures of reference marked thereon, which form a partof this specification.
My invention has relation to improvements in transom lifters and locks; and the object is to provide a simplified and efficient device for the purpose mentioned which can be cheaply I made and which is durable in use and simple and certain in operation.
p The invention consists in the novel construction of parts and their combination, as Twill be hereinafter fully specified and parfticularly pointed out and distinctly claimed. l
I have fully and clearly illustrated the invention in the accompanying drawings,where- Figure 1 is a view in elevation of the complete device shown as attached to the stile of som. Fig. 2 is a detail View of the joint which connects the transom-rod to the arm of the a door and operativelyconnected to the transbell-crank lever. Fig. 3 is a detail perspecrod which operates the device. Fig. Lis an enlarged perspective of the fastening-bracket Fig. 5 is a detail perspective of the device detached.
door or to the upright of a window and so dis- Referring to the drawings, A designates a bell-crank lever fulcrumed to the stile of the posed that the arms are directed upwardly,
as indicated in the drawings.
The fulcrum I l or pivotal support of the lever A consists of a screwprojected into the face of the stile and formed with a plane bearing portion, upon which thelever is mounted and turns, as
shown, and a threaded end, on which a fas- 1 toning-nut 1 is mounted to hold the lever in its proper position.
.13 designates the hand-bar or rod by which the device is operatedwThis consists of a Serial No. 58,693. (No model.)
suitable metal rod held slidingly in screw eyes 2, projected into the surface of the stile", as indicated. The upper end of the rod B is bent at right angles and threaded to receive a holding-nut 3 at its outer end, which angular part is passed through a suitable slot 4:, made in the outer end of the arm 5 of the bell-crank lever. At suitable determined distances at the lower portion of the rod B the rod is notched or flattened, as at 6, and passes through a bracket 7, secured to the stile and formed with a keyhole-slot, through which the hand-rod is free to slide and so that when it is desired to lock and hold the device at a fixed position the rod at the reduced places may be moved into the slot of the keyhole and thus lock the rod and-through the connections with the transom thus lock the transom in the position to which it may have been moved, either open or closed.
O designates the transom-rod having immediate connection to the transom. This rod consists of a metal rod of determined length bent at right angles to its stem at the end where connected to the transom and provided with a collar 8 and threaded extension 9, so that a screweye 10 may be arranged thereon and the screw-eye held in position by a fastening-nut 11, as shown. The screw-eye 10 is screwed into the panel of the transom, as indicated. The upper end of the arm 12 of the bell-crank lever and the outer or lower end of the transom-rod are connected by means of a lapped joint 13 in the nature of a scissors-joint, the flattened portions being faced by washers and held together by a bolt 14, projected through the parts, as more clearly shown in Fig. 2 of the drawings.
The device is assembled and mounted in operative position by first inserting the screweye in the transom at the desired place. Then the bell-crank lever may be mounted in position on the stile of the door. The transomrod can then be secured to the screw-eye in the transom and the outer end of the rod then jointedand secured to the upper end of the arm of the bell-crank lever. The screw-eyes, through which the operating-rod passes, can
then be secured in the desired positions and the rod passed therethrough and its upper end secured to the upper end of the outer arm of the bell-crank lever. The keyholebracket can then be arranged. on the rod, and secured in position, and the device is ready for operation;
To operate the device, all that is necessary is to release the hand-rod from its connection in the keyhole-slot and move it so as to move the transom as may be desired, when the hand-rod is moved into engagement at its reduced places into the slot of the keyhole and the rod with the whole device is held locked in such position.
' What I claim is A transom lifter and lock comprisinga vertically-sliding hand-rod having reduced portions and having its upper end bent at right angles to its stem, at bell-crank lever fulcrumed to the stile of the door with its arms directed upward and the outer one pi-votally secured to the upper end of the hand-rod, a
transom-rodhaving its outer end lapped over the upper end ofthe inner arm of the bellcrank lever and its inner end bent at right angles to its stem and formed with a collar, a screw-eye on the bent portion, fastenings to hold these parts in pivotal connection, a fastening-bolt to pi-votally secure the lapped joints together, and a holding and locking bracket for the hand-rod formed with a keyhole-slot through which the hand-rod passes and with which the reduced portions thereof engage to lock the device, substantially as specifiedl In testimony whereof I affix my signature in presence of two witnesses.
