SPECIFICATION forming part of Letters Patent No. 474,281, dated May 3, 1892.

Application filed January 13, 1892. Serial No. 417,945. (No model.)

To all whom it may concern.: The improvement above referred to is set Be it known that I, VALDO R. BALLOU, of forth in Letters Patent No. 405,057, granted Stamford, in the county of Fairfield, in the .I une 1l, 1889, to the Yale da Towne Manufac- State of Connecticut, have invented certain turing Company upon the application of War- 55 5 new and useful Improvements in Locks, of ren H. Taylor, assigner to the said company. which the following is a specification. In my improvement I adopt the same or a My invention relates to locks Which have similar mode of positively connecting the conindependent escutcheons or tumbler cases necting-bar to the key-plug of the tumbler which are applied on the outside of doors, dac., mechanism, and I pass the said connecting-bar 6o 1o and are connected to the latch-bolt-operating throughaslotin the roll-back ofthe latch-opermechanism by a connecting-bar or similar deating mechanism to any extentrequired bythe vice. thickness or thinness of the door. In order to The general obj ect of my improvements is provide a greater range of adj ustlnent to suit a to render such locks easier of application and reduced thickness of the door Without the ne- 65 I5 to make the adjustment and putting together cessity of cutting oit or reducing the length of their parts by the mechanic in applying of the connecting-bar, as described in the them to use more simple and to insure their Taylor patent, No. 405,057, above' referred to, correct and satisfactory operation without I employ a thumb-knob for the inner side of such nice and accurate fitting as has heretothe latch, excavated or hollowed out axially, 7o zo fore been required. Iam thus enabled to propreferably as far as its length will permit, so vide a lock of this description of the mostimthat the end of the connecting-bar may, if proved and efticient construction which can necessary, extend within the said thumb-knob readily be applied to doors of various thickwhen required in applying the lock to a door nesses by a mechanic ot' ordinary skill. of small thickness. Another difficulty vwhich 75 2 5 One of the difficulties heretofore encounhas occurred in the adjustment and connectered in adjusting to a door or other object tion of the parts of a lock of this character the parts of a lock of this class has been that which are applied to the opposite sides of a the connecting-bar between the escutcheon door has resulted from the necessity of securand tumbler mechanism on the outside and ingtheexternalescutcheon andtumblermech- 8o 3o the latch mechanism on theinside was placed anism by inside fastenings which cannot be loosely into a slot in the end of the key-plug approached from the outside, and the resultof the escutcheon and into a corresponding ing difficulty of adapting the length of the slot in the roll-back or cross-head, which opattaching-screws by which the escutcheon is crates the latch, and there held only by besecured to the `thickness of the particular 85 35 ing iitted approximately in length to the space door to which the lock is applied. In the patbetween these two slots. Such tting of the ent of Vtarren H. Taylor, above referred to, connecting-bar has to be done With considerthis difficulty is overcome in a manner by the able nicety and is not easily accomplished employment of screwsforholdingthe escutchwith suticient accuracy by the tools and skill eon, provided with a series of annular grooves, 9c 40 0f the Ordinary lleOhHiC- so that the said escutcheon-holding screws To overcome the difficulties above referred might be broken ott to approximately the reto, a plan has been devised by which the conquired length: In my present improvement meeting-bar is positively connected at one end I provide a wider range of adjustment Withwith the key-plug, which is operated by the out weakening the screws by the employment 9 5 45 key from the outside, and passes through an of screw-receiving pockets or sockets interaperture in the hub of the roll-back or crossnally threaded for the reception of the screws head, which operates the latch, so that it is and adapted to be adjusted longitudinally in securely prevented from escape without havthe frame of the escutcheon or tumbler meching to be fitted accurately between slots in anisn1,s0 that the said screw-pockets maybe roo 5o the respective parts which engage its oppomade to project to a greater or less extent site ends. within the vopening through the door, according to the thickness of the latter, as hereinafter described.

My invention particularly consists in the provision of screw-threaded pockets 'longitudinally adjustable for the reception ot the holding-screws, alsoin the construction of said pockets with external transverse grooves or. notches engaging with lugs on the tumblercase, whereby they are secured adj ustably; and, further', in the combination of the adjustable screw-pockets and holding-screws, an operating-bar attached to the rotary key-plug, andan interior thumb-knob excavated longitudinally to permit the passage ot the operating-bar to an indefinite distance Within thelock and roll-backs rotated by the operating-bar and thumb-knob, respectively, so as to retract the latch by the key from the outside or by the thumb-knob from within, the whole cooperating, as herein described, to permit the application and operation of the lock on doors of various thicknesses, as described.

In order that my invention maybe fully understood, I will proceed to describe it in detail with reference to the accompanying drawings', in which- Figure I is a vertical section ot my improved lock applied to a very thin door, the escutchcon and tumbler-case being shown in elevation. Fig. II is a vertical section of the same, showing it applied to a much thicker door. Fig. III is a horizontal section of portions of the lock, showing the lock-case and the escutcheon and tumbler-case and their connecting-screws and screw-pockets in plan View, the parts being applied to a thin door, as shown in Fig. I. Fig. IV is a plan view of the escutcheon, tumbler-case, connecting-bar, screws, and screw-pockets detached, showing them in the relative positions which they occupy when the lock is applied to a very thick door, as illustrated in Fig. II. Fig. V is a rear view of the escutcheon and tumbler-case and the screw-pockets for the reception of the screws by which this is fastened to the door. Fig. VI is an elevation of the interior of the lock with the face-plate removed. Fig. VII is a perspective view of the latch-operating mechanism.

A may indicate a part of a door or other object to which my improved lock is applied.

B represents the lock-case on the inside of the door; C, the escutcheon or' tumbler-case, and D the annular escutcheon plate or collar on the outside of the door.

E represents the key to operate the tumblers F and the plug G ot' usual construction in this class of locks.

II represents a connecting-bar to connect the plug G and the roll-back or T-head I, which operates the spring latch or bolt K of usual construction. The key-plug G is provided at its inner end with a lug L and slot for the reception of the end of the connecting-bar H, which is provided with a transverse slot 71, to receive the lug L on the keyplug, thus connecting the end ot the connecting-bar to the key-plug, as described in the patent of Warren H. Taylor, already referred to, positively, but not rigidly-that is to say, the said connecting-bar is secured against endwisc movement and is so confined to the key-plug as to partake ot the rotary movement of the latter; but the free end ot the said connecting-bar is permitted to play laterally in the aperture of the door, so as to facilitate the application on the inside of the door of the latch-case, Within which the inner A end of the said connecting-bar is received and held.

The connecting-bar II is made of sufiicient length to extend through doors of maximum thickness, and it is passed to anindetinite extent, regulated by the thickness of the door, through a slot t' in the roll-back I or T-head, which receives the rotary movement transmitted from the key-hub G by the connecting-bar I'I, and by its arms I acts upon the cross-head or lugs k' upon the ends of the v shank-rods K of the latch to retract the same in the usual Way.

The thumb-knob by which the latch K is operated from the inside is shown at N. This is provided with the customary internal T- head or lugs n, which operate on the lugs 7c ot the latch-rods K when the said thu inb-k nob is turned in either direction, and the shank of said thumb-knob being in line with the con necting-bar Il is excavated or formed with a longitudinal cavity N', extending nearly throughout its length, so that the said connecting-bar may extend and project Within the shank of the thumb-knob to an indefinite extent when required by the application of the lock to a thin door, as illustrated in Figs. I and III.

As is usual with this class of locks the external escutcheon and tumbler-case C' and the annular escutcheon plate or collar D are secured to the door from the inside by connecting-screws T, which pass through a holdingplate'U or lock-case on the inside of the door and enter suitable screw-holes or threaded sockets prepared for them in the escutcheon. In my improved mode of securing the escutchcon and tumbler-case and connecting the holding-screws T thereto I employ adjustable pockets V, internally threaded to provide sockets for the reception of the holding-screws T and having paired transverse notches o in their sides, two or more such pairs of notches being provided at intervals so as to permit the longitudinal adj ustment of the said screwpockets V relatively to the escutcheon and tumbler-case, the said screw-pockets being applied to forked or notched lugs c', projecting laterally from the tumbler-case C', as shown. It will thus appear that in applying the lock to a thin door, as illustrated in Figs. I and III, the screw-pockets V may be retired almost completely within the thickness of the tumbler-case, and thus any necessary part of the length of the screws themselves may be taken up Within the thickness of the IIO tumbler-case, so as to bring the holdingplate U as close to the inner face of the tumbler-caseas the thickness of the door may require. If the lock is to be applied to a slightly-thicker door, this can be accommodated Within the limit of the length of the holding-screws without shifting the screwpockets V; but for a much thicker door the screw-pockets are advanced to the position shown in Figs. II and IV, the projection of the said screw-pockets being supplemented by any necessary part of the length of the screws themselves. I thus provide a range of adjustment to suit variations in the thickness of doors nearly equal to the length of the holding -screws added to the distance between the notches on the screw-pockets. By this simple and ready means of adjustment I adapt the same lock and its attachments for application to a door of any thickness within usual limits-say from seven-eighths of an inch to two and one-fourth inches. It is manifest that screw-pockets ot greater length and with more than two pairs of notches may be employed, if it be desired to adapt the lock for application to a door` of excessive thickness, or longer screws or pockets may be provided in addition to those represented, which are proportioned to correspond nearly with the length of the tumbler'- case, so that the holding-plate may be brought nearly in contact with the inner face of the tumbler-case, as shown in Figs. I and III, in applying the lock to a thin door.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

l. A tumbler-case or escutcheon member for locks, provided with screw-threaded pockets longitudinally adjustable relatively to said tumbler-case for the reception of the holding-screws by which the said tumbler-case is secured to a holding-plate on the opposite side of the door, as explained.

2. In combination with the escutcheon or tumbler-case and a holding-plate or internal lock-case and connecting-screws for securing the same to a door, the screw-pockets V, provided with notches U, and lugs c on the tumbler-case for securing the screw-pockets adjustably to said tumbler-case, substantially as and for the purpose set forth.

3. The combination of an escutcheon or tumbler-case with longitudinally-adjustable screw-pockets, holding-screws engaging in said pockets to secure the escutcheon to a holding-plate on the interior of a door of .any required thickness, a latch-bolt and slotted roll-back for actuating the same in the internal lock-case, a connecting-bar rotated by a key-plug in the escutcheon and passing to an indefinite distance through the -slotted roll-back and transmitting rotary movement thereto, and a hollow thumb-knob permitting the projection of the connecting-bar within it, the whole co-operating to permit the adaptation and application of the attaching-screws and the operating-bar to doors of various thicknesses, as explained.

4. The combination of the tumbler-case C', rotating plug G, connecting-bar H, slotted roll-back or cross-head I, door-latch K', thu mbknob N, excavated longitudinally for the reception of the projecting end of the bar, connecting-screws T for securing the tumblercase to the door, and the screw-pockets V, longitudinally adjustable relatively to the tumbler-case to permit the application of the lock to doors of different thicknesses, substantially as explained.
