RUDOLPH M. HUNTER, OF PHILADELPHIA, PENNSYLVANIA.
LATCH AND LOCK COMBINED.
SPECIFICATION forming part of Letters Patent No. 464,282, dated December 1, 1891.
Application filed May 22, 1891.
To all whom it may concern:
- Be it known that I, RUDOLPH M. HUNTER, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Latches and Looks for Doors, of which the following is a specification.
My invention has reference to latches and locks for doors; and it consists of certainimprovements, which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.
My invention set out in this application has for its object the construction of a door-lock which shall be easily and quickly applied to doors, saving a large portion of the present cost in labor for attachingthe lock to the door.
My invention also has for its object an economical construction whereby the cost of 'a fine appearing lock and handle shall be reduced to a minimum.
Furthermore, my invention, while combining simplicity and cheapness, embodies a construction employing tumblers or dogs, which permit the greatest security which could be desired for a door-lock of this character.
My invention will be best understood by reference to the accompanying drawings, in which I Figure 1 is a sectional elevation on line mm of Fig. 2 of a door-lock embodying my invention. Fig. 2 is a sectional front elevation, part being taken on line y y and part on line 2 z of Fig. 1. Fig. 3 is a perspective view of the bolt-socket with the two halves separated. Fig. 4 is a sectional plan view through the bolt-socket and box-lock and shows the bolt and its spring in plan. Fig. 5 is a cross-section of the bolt and socket on line to w, and Fig. 6 is a side elevation of the key.
A is the door. vIn the end of the doora hole B is bored, and into this is fitted a socket 0, formed of the two halves O and O of substantially the construction-shown in Fig. 3. hen these halves are placed together, the lugs c fit down into the recesses c to prevent lateral or longitudinal movement of the two halves relatively to each other. Furthermore, the projection c at the rear of one part projects into the recess or notch c on the rear of the other part, there by steadying the rearend against lateral movement aswell as the for- Serial No. 893,696. on model.)
ward end. \Vhen these two parts are together, the notched portions 0 form a slot. The front portions of the parts 0 and O are provided with flanges C through which screws are passed to hold the socket in the door, as
is placed between the end of the socket and the end of the bolt D, as best shown in Fig. 4, so that the bolt D is always pressed outward with the spring action. The front end of the bolt is made with the oblique nose d for catching into the box-lock F, which is secured by screws to the door jamb or frame. The bolt D is reduced in weight by forming its middle portion flat, as indicated at D which construction also permits the em ployment of the parts a and c in the socket. After the bolt and socket have been placed in the door a pin 6 is passed laterally through the slot 0 and screwed into the bolt B, as shown in the several figures. A second hole A is bored through the door transversely to the first-mentioned hole B and may be somewhat larger than the handle-shaft G to avoid friction.
J and J are two face-platesin which the bandle-shaft G is j ournaled, and are secured upon opposite sides of the door by means of screws N in the ordinary way.
K are the handles, which are secured to the handle-shaft by means of screws L or otherwise. The shaft G is formed with a longitudinal slot 9 throughout its length, in which the key P is thrust when the door is to be opened or the lock kept in condition, so that by turning the handles the door may be readily opened. The handles also have an opening in their ends through which the key may pass. The key is preferably provided with a head 19 to limit the extent to which it enters the slot, and also is provided with the notched portions R and R, which are similar but, arranged in opposite directions for the purpose ofT-opening the look from either side of the'door. One of the face-plates J is made recessed upon itsunder side and is prefer,-
ably fittedagainst a disk I and forms a circular or annular compartment in which the tumblers H are placed. That portion of the shaft G which is inclosed between the faceplate J and the p ate I is slightly enlarged and made square, as shown at G, having the twofold purpose of acting as a bearing for the tumblers, and also properly adjusting the shaft G on the door and holding it in position, even should the handles be removed.
The tumblers H are preferably shaped as shown in Fig. 2 and provided with central rectangular opening 11, which fits over the enlarged square portion G of the shaft, so that when the shaft is turned the tumblers are turned also. when the tumblers are turned with the shaft, the bolt D is moved backward against the action of the spring E to unlock the door. These tumblers are also provided with slotted upper portions H so that when they are raised to the proper elevation the said slot or notch H are in line with the projection 2" upon the inner face of the faceplate J, (or, if desired, upon the disk I.) When the tumblers turn, they pass over the said projectionwithoutopposition. Ifthetumblersare not raised to their proper heights, the projection t' offers an obstruction to their movement, and thereby locks the handle-shaft against movement, and consequently the bolt cannot be withdrawn. The several tumblers are provided with projecting portions 72, which extend down into the slot 9 of the handle-shaft G and are adapted to be actuated by the notched portions of the key P, so as to elevate the tumblers to the requisite heights to insure the slots or notches H coming in line with the projection 2'. 1 As the tumblers are all located in one of the face-plates and are upon one side of the door, the notches R of the key, which would operate the said tumblers from the right-hand side of the door, would not operate the tumblers from the other side of the door, as is self-evident from an examination of Fig. 1, and consequently the key P is formed with notches R for operating the tumblers from the left-hand handle. The handles are preferably recessed on their ends, as indicated, so as to receive the head portion of the key and prevent it pro jecting'beyond the handle both for comfort and ornamental appearance. When the door is closed, it is not necessary to turn the ban: dle, as the bolt may be pushed back against the action of the spring without affectingthe tumblers in any manner, and consequentlythe same bolt D acts both as a latch and -a look. When the key is thrust into the end of the handle, the door is unlocked and may be opened bysimplyturning the handle; but when withdrawn or partly withdrawn the tumblers are locked against movement and the handle cannot be-turned or the bolt withdrawn.
So far I have described my invention as applied to interior doors, or those between bedrooms and halls, where both handles are either the door.-
the cheap and economical constructionherein locked or unlocked with reference to move ment, andI will now describe a slight modi fication to my invention which is adapted to front doors,in which case the key is designed to open the front door from the out-side, and its insertion is necessary to the turning of the handle from that side, but in which the inner handle may be turned at any time for opening the door without the employment of a key. This movement is indicated'in the dotted lines in Fig. 1, and consists simply in extending the pins ethrough the face-plate J and, securing the inner handleKloosely upon the shaft G,or so. that it may be rotated without turning the shaft G and connecting it with the bolt-by means of a lug M, having a slot m, into which the pin 6 extends, so that upon turning the handle the bolt D may be drawn back even when the shaftG and the tumblers are locked against movement. this manner the door may be opened fromthe inside at all times without theuse Off/116 key, but cannot be'opened from the outside without the insertion of the key.
If desired, in place of the usual devices employed for unlocking the front hand-le,-so-
that the (1001' may be opened from the outside, for temporary use I may arrange toinsert the key from the inside, as before described, and allow it to remain therein so long asthe door is desired to be unlocked forthe free opening of it from the outside without IOO the employment of thekey fromthat side of By this means I accomplish with set out all that is accomplished by the -ordi nary expensive door-locks,
per cent. in the time required to apply the lock to the door, which is a point of great im- Aside from the reduced cost in the manufacture of the lock. proper there is asaving of about seventy-five portance when considering large building operations.
While I prefer the construction herein set out, I do not limit myself thereto, as'the details thereof may be modifiedin various wayswithout departing from the principles ofmyinvention. Y
