Specification of Letters Patent.

Patented July 27, 1909.

Application led August 1, 1908. Serial No. 446,362.

To all 'whom 'it may concern:

Be it. known that I, HENRY G. VoiGH'r, a citizen ol the I Tnited States. residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Locks, ot' which the following is a full, clear, and y'enact description.

My invention relates to improvements in door locks.

The object ot the invention is to provide a new type of lock, which is so constructed as `to be very easily applied to a door, eliminating the necessity of the usual mortise and requiring but very littleI cutting of the door stile to receive the several parts.

Sonie of the other advantages are sim plicity of construction, compactnes's, economy of manufacture, ease of assembling', strength and durability.

In the accompanying drawings, Figure 1 is a perspective view of the lock assembled and looking from the front. Fig. 2 is a similar view looking from the rear. Fig. 3 is a vertical section of the lock case, certain elements being shown in elevation.` Fig. Ll

is a horizontal section. F ig..5 is a plan view of a lock case, with.the internal parts detached. Figs. G and 7 are end elevations of certain details. Fig. 8 is a vertical section of one of the knobs and rose plates, certain parts being shown in elevation and partly broken away. F 9 illustrates in section and in end elevation a detail. Fig. 10 illustrates in end elevation and side elevation an- .other detail. Fig. 1l illustrates in side elevation and end elevation still another detail. Fig. 12 illustrates a key.

It should be understood that I have shown my new lock only in one of its preferred forms, appreciating that a large number of modifications may be made without departing from the spirit and scope of my invention.

In the preferred form of my invention shown in the dra-Wings, l represents the front. or face plate of the lock, said plate carrying at its rear'a tubular case, preferably of round cross-section and preferably slit so as to form the two sections 2 2, which sections .may be opened, as shown 1n Fig. 5, to permit the internal parts to be assembled therein.l

3 4 are knobs. 5 6 are escutcneons or rose plates, through respectively, each rose plate affording a sultable bearing for its knob.

In Flg. 8 I have shown the knob l and rose 6 in section and illustrating one couvenient form for assembling said parts. In

this figure the knob -t is provided with the shank 4a, which is ott'set at its inner end, as at 4b, to hold the knob to the rose G. This inner end of the knob shank carries the bars 7 8 so that when the knob 4 is rotated, said bars 7 8 will move therewith.

In case the lock is to be provided with a key, such, for example, as the key 9 (Fig. 12), said key may be entered through a suitable passage 10 in the end otl the knob, and may be so constructed as to operate a spindle 11. The particular form or purpose of the-key mechanism is immaterial to this invention in its broadest aspect. As shown, the key-controlled spindle 11 runs parallel with the bars 7 8. l2 is an alining member or bar also carried by the rose (i. This aliner is arranged to engage a notched extension 2b (Fig. 3) at the rear of the lock case, while the bars 7 8 are arranged to engage in notches 13 14 respectively, in a roll-back 15. The side walls 'of the ease sections 2 2 are cut away sutiiciently to afford clearance for said bars and to permit the same to rock as the knob is turned to ably connected with the latch-bolt. In the particular foi-.u shown, this latch-bolt comprises twov members 1(3 17, each beveled on one side in the usual manner, and provided at the rear with the tails 1G 17?, which latter may have hooked extremities, as shown, to permit of engagement by links 18--19, which latter connect the latch-bolt with the roll-back 15.

From the foregoing, and referring particularly to Figf 3, it will be seen that the roll-back 15 may be oscillated in either direction, and Will retract the latch-boltl heads 1( 17 against the inlluence of the projecting spring 1Gb.

When a key locking mechanism is provided, I. may employ a dead-bolt 20 adjacent to the latch-bolt heads 1(5 17 and preferably between them. This dead-bolt 2O has a tail '20, which is connected by alink 21 with a roll-back 22 concentric with rollback l5, butl free to move independently thereof.V The spindle 11 makes engagementi with the roll-back 22 so, that when a proper rock roll-back l5. rIhe roll-back l5 is suity appearance when in place.

- quired to prepare it to receive the lock.

example, the bar 7 is telescopic witln the com )anion )art Ta'the bar 8 is telesco ic with a similar companion part (not shown) the bar 12is telescopic with the companion vpart 12, and the spindle 1l (which is of rectangular cross-section) is telescopic with the companion part lla. In this particular instance these companion parts ofethe spindle ll and l1a do not slide, one within the other, but instead overlap, each being slabbed off on one side to produce, when placed together, the proper cross-sectional outline to fit within 'the roll-back 22. By

nf this means the knob sections may be moved to and fro to adapt the apparatus to doors of different thicknesses. When all of the parts are assembled (as shown inA Figs. l and 2) the plates 5 6 may be secured together by suitable holding screws (not shown), and since the parts described hold the case and the various parts of the lock mechanism in their embrace, there is no danger of any of said parts becoming detached or lost.

When a vcarpenter desires to apply such a lock to a door, it is merely necessary for him to remove the holding screws and separate4 the three sections (the case section and the two knob sections), lHe then bores a hole into the edgeof the door stile of suitable size and depth to receive the lock case. The face plate is preferably tapered or flared outwardly so as to' make a snug lit `in-this bore, thereby producing a inished and handsome The carpenter then bores a single hole transversely through the door stile, intersecting the first-mentioned bore. This transverse hole is 'of a sufficient size to permit the moving parts between the plates 5 and 6 (when assembled) to have the proper freedom of movement. This is all-the cutting ofthe woodwork that is s soon as these two bores have been formed, the lock case section is forced into place, and finally the two knob sections are applied from opposite sides of the door, the telescopic parts being brought together in proper alinement to permit said sections to be` lpushed toward each other until they bear firmly upon the two faces ofn said stile. Suitable holding screws may then be applied. In the particular form Sliown, the\ knob t may represent the outer knob, While the knob 3 may represent the inner knob. In this arrangement the holding screws would obviously be passed through the inner rose plate 5 and screw into the rear of the rose plate 6, for by this arrangement it would be impossible for any one on the outside to remove the rose plate 6 and thereby gain access to the lock mechanism.

-It should be stated that the rear side of the rose plate (when provided with a cover plate, as shown` in Figs, 1,-2 and 8) should have suitable clearance spaces, as indicated in the drawings, to permit of the oscillation of the telescopic roll-back operating bars 7-73 8-81. These clearance spaces are clearly indicated in Figs. l and 2. l/Vhen a dead-bolt is provided, a key hole may be provided-l in each ,knob so that the door may be locked or unlocked from either side. form of dead-locking means may, of course, be modified at will. Instead of providing a dead-bolt, suitable dogging mechanism (key operated or otherwise) might be provided to prevent entry from the outside save by means of a suitable key. Many such dead-locking devices are well known, and while I lay no claim to any particular form herein, I wish tohave it understood that I regard a deadlocking device for the latch-bolt as an' equivalent, in a broad sense, of the dead-locking bolt when usedin the aforesaid connection in this type of lock.

In the details illustrated in the drawings I have shown such parts as may be found in the assembly views employed. These, of course, may be modified at will.

The detailishown in Fig. 9 represents a suitable head foi-. the spindle 11, said head being indicated at 1lb. vided with notches 11c to receive the projections 9a at the forward end of the key, where` by when said key is inserted and turned, the

head 11b, spindle 11 and roll-back 22 willA also be turned. The detail shown'in Fig. 10 1s a carrler 23 arrangedto vbe secured to the head 4b of the knob shank, and to in turn support the bars 7 8.

This head is pro-` The particular The detail shown in Fig. .11 represents a ward mechanism 24,.through which thekey passes, and in which it cannot be turned unless the key is properly notched or bltte'd to clear the wards. V .4 l

It will be observed that the entire mechanism is exceedingly compact. The employment`of toggle connecting links between the roll-backs and the bolts permits me to employ a' relatively small or short roll-back, the toggle link connection. compounding the action so that with a comparatively small throw of either roll-back a very substantial movement of its bolt will occur.

Another feature of improvement will be found vin the fact that bars 7 and 8 per-- form a second function", to' Wit, that of re inforcing and alining the parts when assembled, and in this respect supplementing the action of the alining bar "12, to firmly hold the several sections in their proper relation to one another.

By locating the dead-bolt between the two heads of the latch-bolt, I attain not only the advantage of compactness, but at the same timeso position said parts that any strain upon the door will not tend to twist the latch-bolt or dead-bolt, the present arrangement centralizing or balancing said sti-(ain.

As shown in Figs. 4 and 5, one of the sections 2 of the ease may be rigidly secured .to the face plate, while the other section, 2, is detachab'ly secured by means of a spring detent. at one end, its other end being centered and held within the recess in the rear of the face plate. This avoids the necessity of special holding screws.

Another noteworthy featureV of advantage resulting from the construction heretofore described, is that nearly all of the parts may be formed from sheet or wrought metal, tlereby attaining great economics.

As be'st seen in Fig. l, the rear end of the case formed between sections 2-2 is preferably shaped or flattened vertically so as to form bearing walls to support the roll-backs 1.5722, while directly at the rear or at some convenient place within the case, a spring 26 may be employed to hold the roll-back 22 in position to frictionally maintain the deadbolt 20 in its projected or retracted position. The alining bar 12 also performs another important function, to Wit, that yof anchoring or tying the lock case section in place in the door stile. This end is attained by reason of the fact that when said alining bar 12 is in place'in the perforated or notched extension l2b at the rear of the case, the lattercannot be moved laterall of the bar, and since the bar is securely he d by the rose members, and since the latter are securely held to the opposite sides 'lof the door by the holding screws," 't follows that the case section is positively held against longitudinal displacement, a feature of' decided advantage, because with the case longitudinallydisplaced it would tend to cramp or bind the knob shanks and the key spindles and associated parts.

'The carrier 23 serves not only to support the rods 78, but also operates as a spacing `element to prevent the knob from being pushed in. In the form shown, the carrier 23 may be riveted to the head yl" of the knob shank by means of the extensions 23a, while at the opposite end of the carrier 23 the central portion of said carrier may be projected forward, as'indicated at 23D, to form an annular bearing to take up against the inner side of thecover or back plate 2611 of the rose 6.
