CELL-DOOR-LOCKIN DEVICE.

Specification of Letters Patent. at t 1, 9

Application filed May 17, 1915. Serial No. 98,185.

To all whom it may concern Be it known that I, EMILIO Ponno, a subject of the King of Italy, residing at Albany, in the county of Alameda and State of California, have invented certain new and useful Improvements in Cell-Door-Locking Devices, of which the following is a specification.

This invention relates to improvements in looking devices for cell doors and more particularly an arrangement by which such doors may be opened and closed either singly or together from .a given station outside of the cell corridor.

. Another object of the invention is to so arrange the various mechanisms that all parts are closed thereby preventing tampering by an unauthorized person.

Still another object of my invention is to provide means by which the doors may be locked in their closed position and held in their open position until released from the central operating point. 7

With these and other objects in view my invention consists in the novel construction, combination and arrangement of parts herein illustrated and more specifically pointed out in the appended claims.

Reference being had to the accompanying drawing forming a part of this specification,

Figure 1 is a viewin front elevation showing several cell doors, together with the operating mechanism of the same.

Fig. 2 is an enlarged view in plan showing the mechanism associated with one door.

Fig. 3 is a view in section on 33, Fig. 2.

Fig. 4 is a view in section on 44, Fig. 2.

Fig. 5 is a view in elevation of one of the selector mechanisms by which the various doors are connected to the operating shaft. Fig. 5 is a View in elevation of one of the door latch-lifting devices.

Fig. 6 is a view in elevation of the member by which the locking mechanisms are lifted and by which the same are locked when the door is closed. 1

V Fig. 7 is a view in vertical section through the channel on one side of each door showing the manner of locking the latter.

ig. 8 is a view in section through one edge of the door and the abutment thereof.

, Fig. 9 a is an enlarged sectional view through the operating shaft showing the yoke member. for imparting longitudinal movement to the said shaft.

Fig. 10 is an enlarged view in plan of the end of the shaft by which the various doors are operated. Referring to corresponding parts in the several views by the same numerals of referenoe, 1 denotes the front wall of a row of cells, the openings therein being closed by doors 2. These doors may be of any preferred construction and are provided with the hangers 3 carrying grooved wheels 1 by which the doors are suspended on a suitable track 5.

On the upper end of the hangers is mounted a strip 6 eXtending the length of the door and provided with an inclined end 7 adjacent to which is a notch 8 for the purpose hereinafter described.

Along one side of the door and forming an abutment for the latter is a jamb 9 formed of the U-section 10, and the web 11, the latter being riveted or otherwise fastened. The cell wall projects into a rabbet in the side of the door 2, thereby covering the crack be tween the door and its abutment. The portion 10 is provided with a slot 12 wherein is a bar 13 having a limited longitudinal motion with respect to the member 9. The U-shaped portion 10 is provided with a transverse opening 14 through both walls, and the door 2 is provided with a hookshaped catch 15 adapted to pass through this opening. This catch has an inclined face which may engage member 13, raising the latter, which then falls behind the shoulder on the catch, thus holding the door in its closed position until member 13 is again lifted.

Member 13 extends upwardly past the angle 5 which forms a track for the door and the upper end is provided with the lateral extension 16, the inside of which is, under certain conditions, adapted to drop into the slot 8 of member 6. When the extension is in this slot it will be apparent that the door is held in two places, at the upper portion by virtue of 16 entering the slot 8 and at the center by means of the shoulder on the latch 15 being engaged back of the lower end of member 13. A suitable guide 16 is provided at the upper end of bar 13 to prevent side bending thereof in case of attempts to force the door.

On the hanger 3 adjacent the inclined end of member 6 is provided a bracket 18 having the forwardly projecting fingers 19 through the medium of which the door is moved from its open to its closed position, and vice versa. The upper portion of the door and the associated mechanism is inclosed in a rectangular case, denoted in general by 20. This case being so arranged that the various mechanisms described are completely inclosed, thereby preventing any unauthorized person from tampering with the same. The front of this casing, denoted by 21, is longitudinally slidable so that any portion of the mechanism is readily accessible.

Mounted in the front of the casing thus formed is a shaft 22 which is both revolubly and slidably j ournaled at suitable intervals. On this shaft for each door are keyed two members denoted by 23 and 2 1, the former member being provided with means whereby all of the doors, or any particular door may be selected and moved longitudinally while the latter has means whereby the latches of the various doors may be lifted when said doors have been selected for opening, but capable of preventing the raising of the latches of those doors which have not been selected. Each of the members 23 is shown as provided with a conical shaped portion 25, a cylindrical portion 26, and a collar 27, but the shape is ii'nn'iaterial, being a mere structural detail. The collar 27 is provided with two wards 28 and 29. The wards 28 on all of the members 23, project from said members at the same angle, but the wards 29 project at different angles, the former being used when all the doors are opened sin'iultaneously, while the latter is used to selectively open any individual door.

WVhen the door is in its closed position the collar 27, together with its ward, are spaced between the fingers 19 but the distance between these fingers is such that the collar has some travel before the wards engage the fingers 19. Member 241 is provided with two projecting lugs 30 which for any door are spaced in the same angular relation as the wards 28 and 29 of that door, and each of these lugs is provided with the inclined faces 31 adapted to contact with the underside of the hook 16. Also above these locks is a shoulder 32 which when the doors are all to be held closed may be brought into contact with the top of hook 16, thus preventing the latter from being raised.

The strip 6 is provided with an additional notch 36 and pivotally mounted to one side of the door is a latch 37 extending outwardly from the wall and normally resting on the tooth sprocket gear 42 keyed on the same shaft with lever 40, this sprocket being connected by means of a chain in a tooth gear 4 1, mounted on a square shaft 45. This shaft is pivotally mounted in a bearing bar a6 and extends into a square opening in the end of shaft 22, whereby the latter is slidable on shaft 45 but is rotated by the latter.

The end of shaft 22 is provided with a grooved collar 46 about'which is a yoke 17, this yoke being slidably mounted on a bar a9 positioned parallel to shaft 22 and being provided on the underside with ears 50 between which is pivotally mounted the lever bar ell. The latter pivotally mount ed to the frame-work of the cells as shown at 52 and working over a stationary segment 53. Adjacent the lever 41.15 a tooth segment 54:, each tooth corresponding to a given operative position of shaft 22.

I'laving thus described the various details of my invention its operation isas follows First, if a given door is to be opened, lever 40 is moved until the pawl drops in the notch corresponding to that door. Then through the chain 4-3, sprocket -24 is rotated, turning with it the shaft 22 so as to bring the ward 29 of the selected door into alinement with the fingers 19 of that door. At the same time the member 30, in alinement with ward 29, is positioned underthe hook 16 of that door, the handle 41 is then moved so as to slide the shaft 22 longitudinally, the first movement of the shaft causing the inclined faces of member 30 to raise the hook 16 and thereby the member 13, which in turn lifts this member from. the notch 8 and from back of the shoulder on catch 15.

During this lifting movement the ward 29 has been moving from one finger 19 to the other so that by the time the door is released the ward has contacted with the second finger 19 thereby moving the door in the direction of the arrow, which movement is continued as long as lever alis rotated. A stop is provided for the door so in its extreme left position the notch 36 is positioned under the latch 38. Thus if it is desired to have the door held in its open position lever 10 is again rotated to its extreme position whereby the wards clear the fingers 19 thus allowing the shaft to be moved to the right without carrying the door with it and as the member 23 is moved from under the bar 37, the lock on the latter drops into the notches 36 and thereby holds the door against being closed. ,In closing the door, lever 41 is shifted in the opposite direction, causing member 30 to lift latch 37, after which the door moves to closed position.

If it is desired to open all the doors simultaneously, handle 40 is rotated to the position in which the wards 28 aline with the corresponding finger 19 of each door so that when the handle 41 is moved to slide to the door longitudinally, all doors are opened. The doors are closed by the opposite move of handle 41, and after being closed the shaft 22 is rotated to the position where the wards clear the fingers of all doors. When the handle 40 is again moved, the position is reached to impart to the shaft a slidably longitudinal movement whereby the shoulder 32 is brought over the top portion of hook 16. The handle 41 is locked in this position by means of a suitable pawl and slot arrangement, and in this manner it will be impossible for the latch bar 13 to beupraised.

While I have shown and described the preferred embodiment of my invention it will be understood that minor changes may be made in form and detail without departing from the scope of th claims.

' l Vhat I claim as new and wish to cover by Letters Patent is 1. The combination with a plurality of sliding doors, a shaft slidably and rotatably mounted above said doors, selectors attached to said shaft adjacent each door, wards on said selectors, fingers extending from said doors, means for rotating said shaft to bring the wards into engagement with said fingers, and means for longitudinally shifting said shaft to impart movement to the door by means of the engagement of the wards and fingers.
