GILES A. BEOKWITH, OF WATERFORD, CONNEOTIOUTJ LOCK.

SPECIFICATION forming part of Letters Patent No. 506,461, dated October 10, 1893.

Application filed April 8, 1893- Serial No. 469,576. (No model.) i

To all whom it may concern.-

Be it known that I, GILES A. BEoKWI'rH, a

' citizen of the United States, residing at Waterford, in the county of New London and State of Connecticut, have invented anew and useful Mortise Lock and Rose, of which the following is a specification. I

This invention relates to that class of mortise locks which have cylindrical cases adapted to be inserted in a hole bored with a bit or auger, and also of a special form of rose or escutcheon that dispenses with the use of screws being adj ustably interlocked in connection with a companion member of a substantially similar nature and that can be adjusted without removing the knob from the spindle that passes therethrough.

The object of the present invention is to economize space in the construction of the lock and at the same time to provide for an easy application of the same to a door and requiring a simple formation of mortise; and also to provide for a simple mode of adj ustment of the roses or escutcheons to compensate for the shrinkage of the door to which it may be applied.

With these and other objects in view the invention consists of .theconstruction and arrangement of the parts thereof as will be hereinafter more fully described and claimed.

In the drawings: Figure 1 is a sectional perspective view of a part of a door, showing the improved lock and roses or escutcheons applied thereto. Fig. 2 is a longitudinal vertical section on the line -00, Fig. 1. Fig. 3 is a transverse verticalsection on the line yy, Fig. 1. Fig. 4 is a detail perspective view of the parts of the lock disconnected from the door. Fig. 5 is a transverse vertical section of an ordinary form of a knob and knobspindle, showing the improved roses or escutcheons in connection therewith.

Similar numerals of reference indicate corresponding parts in the several figures of the drawings.

Referring to the drawings, the numeral 1 designates the door, in the edge of which is formed an elongated mortise 2, that is constructed by boring a short distance into the door two round holes, spaced apart, and the intermediate wood removed, and centrally in the said mortise is formed a circular mortise 3 that extends considerable distance into the door and slightly in advance of the rear end of the said mortise 3 is formed a transverse circular opening 4 that extends entirely through the door. The mortise 2 receives a face-plate 5, that is integrally constructed with the outer end of a sectional lock-barrel 6, that is inserted in the mortise 3, and incloses a spring-latch 7, that is arranged to be operated by a knob and spindle, or, if desired, can be controlled by a key, but it is preferable that a knob and spindle be used.

The latch 7 consists of an engaging end 8 that is arranged to coact with a keeper of suitable form, and has an elongated body 9, with a slot 10 extending therethrough, and within the said slot, and bearing against one termination thereof is a spring 11, whose rear end bears against a lug 12, integrally formed with the barrel 6, and by means of the said spring theengaging end 8 is normally held distended beyond the face plate 5. 'The rear end of the body 9 is reduced and formed with a yoke 13, having lugs at the terminating ends of the said yoke that are arranged to be engaged by an operating arm or cam carried by the spindle 14, which is supplied with knobs 15 on opposite sides thereof. ,Opposite side portions of the barrel 6 are slotted, as at 16, to permit the play of the said yoke of the latch therein, and intermediate of the rear parts of the slots 16 islocated another lug 17, having an opening 18 therethrough through which the spindle l4 transversely passes. The arms of the yoke 13 move against opposite sides of the log 18 when the latch is drawn backwardly in the barrel 6. A removable section, 19 is fitted over the body 9 and yoke 13 and held in fixed position by a screw 20 that is removably mounted in the lug 12, and this section is formed with an opening that aligns with the opening 18 in the lug 17 to permit the passage of the spindle entirely through the barrel 6. Thus it will be seen that the latch is arranged in compact form within the barrel 6, and by inserting the latter in the mortise 3 the entire latch is placed in operative position in the door without forming other slots or recesses, and held in position by two screws, one of which is located at the upper part of the face-plate 5 and the other at the lower ISO part of the same, and when the said barrel is in position in the mortise 3 the opening 18 in the lug 17, as well as the opening in the section 19, aligns with the circular opening 4 and located in the center of the latter. The spindle 14 is then passed through the said opening 18 and the opening in the section 19, and with the knobs thereon is secured in positive connection with the door when the latch will be arranged for operation. In the opening in the section 19, and resting against the lug 17, is a collar 21 that projects into the said opening in the said section and serves as a bearing for the spindle to hold the latter in proper relation to the remaining parts of the latch, and for operating the latter.

To hold the spindle inplace, and for other well known purposes, two roses or escutcheons 22an'd-23 areemployedof anovelform with an important advantage. with the'escutcheon23 is a sleeve 24, having an opening 25 extending transversely therethroughthroughwhich the barrel 6 extends, and provided at theinner surface of itsterminating end witlrscrew-threads '26. said sleeveflet fits snugly in the opening 5, and integrally formed with the roseor escutcheon 22 is a collar 27, havingexterior screw-threads 28, and said collar is less in diamete'r than the sleeve 24: audisso arranged that the'screw threads 2S= thereof properly engage the'screw-threads-26 of the said sleeve. The outer exposedsurfaces of the roses or escutcheons may besuitablyornamented or embellished with designs, and each of thesameat the center is formed with a socket-29 that-surrounds the central spindle-opening to receive the inner opposi n g central collars of the knobs- 15. lhe central part of eaclrrose or escutcheonyaround thesocket 29 therein,is projected outwardly or slightly flanged circularly, and on'the rose or escutcheon 22, in connection with said 'central flange thereofgare' formed two oppositely-disposed parallel shoulders 30; that are adapted to be engaged by a wrench or otherbifurcated tooltoturn the said rose or escutcheon 22 either to properly fit the collar 27 the1'eof into the sleeve 2e when apply ing thesame to the door, or'to adjust the said rose while the knob and spindle are inposi Integrally formed- Th e r tion to compensate for shrinkage of the door. Bymeans of the construction just set forth, it will be observed that no screws or other fastenings are necessary to hold the roses or escutcheons in place; and further, that the said escutcheons may be readily adjusted without removing either of the knobs of the spindle for the purpose stated.

It will be understood that the roses or escutcheons herein set forth may be equally well employed with any form of knobs, irrespective of the construction of the latch or look, and owing to the simplicity and cheapness of construction, as well as the small amount of labor required to apply the several parts to a door, avery noveland valuable acquisition to the artis produced.

Changes in the formgproportion,and-the minor details of construction may be resdrted to without departing from the principle or sacrificing any of "the advantages of this invention.

Having described "the invention, what is clai1ned--as new'is- The combination with a cylindrical lock-casing, 0f-a transversely-disposed sleeve adapted to extendfrom one surfaceofa door to the other and terminate flushwith such surfaces, having a circular diametrical opening tdre ceive the rear end ofsaid lock-casing, and provided at one end witha fixed roseor escutcheon to bear against one'surf'ace of the' door and at theother end with an interior-screwthread, asecond rose or escutcheon'removably "attached to theother end of the sleeve and having an exteriorly th readed collar" to=fit l in the interiorly-threaded end of said sleeve, and a'spindle'extending axially through the sleeve and transversely through the lock and 'said spindle being provided with terminal knobs, substantially as specified.

In testimony thatI claim the foregoing as it my own I have hereto aiiixed my sign ature in the presence of two witnesses.

GILES A. BEGKNVITH.
