sPnCrFIcATIon arming pare of Letters PaeeneNo'.' 707,375, dated August 1e, 1902. Application led-April 16, 1902. Serial No. 103.194,4 (No model.)

To all whom it u'tctyoucerrt: Be it known that L'WIL'LIAM S. BAR'ITIIOLO- MEW, a citizen of thevUnited States, residing i `thirnble consisting of a circular flange h, threadedto screw into av depression G and vhaving'a reduced body h, also threaded.

at Wyncote, in the county of Montgomery and State of Pennsylvania, have invented certain new and usefullmprovements inDoor-Knob Attachments, of which the following is a speciication, reference being had to the accompanying drawings, forming part thereof. A

My invention relates to a door-knob attachment wherein the knobs for operating the latch may be applied thereto irrespective of the thickness of the door with which it is used. The object of my improvement is to produce a deviceof `simple construction andI ready application to adoor and the likeby l means of which'the knobs or handles may be secured to the frame of,` a mortis'e lock or latch by adjustable members 'so arranged that regardless of the thickness ofthe dooror its mountings within certain limits the knobs may be fastened in place. Y f

Referring to the'd'rawings, Figure lis a sectional View through part of a door andthe upper end of a mortise-lock, showing my invention applied to a door of extreme thickness. Fig. 2 is a similar View, the door `being of decreased thickness. perspective views of opposite sides of a part of the cover-plate. Fig. 5 is a perspective View showing the knob and rose connected.

- Fig. 6 is a similar View of a detail of construction. Fig. 7 shows a modication.

Similarfletters of reference indicate similar parts inA-the respective iigures.

Into the edgeofa door A is mortised a lock,

the frame of which'consists of the casing B and cover-.plate C. Through the upper part of the lock and also through the door A pro;

jects a spindle -D for operating the latch or latch-plate E through the medium of the hub or stump F in the ordinary way. Depressions G, concentric with the axis of the spindle D, are formed in the casingB and cover-A asshown in Fig. 2.

Figs. 3 and 4 areA `the and latch-plate E, operated by said arms. Y' j H H, Figs'l', 2, and 6, are vthimbles, each Through each thirnble H is an opening of two diameters, the larger opening h2 fitting freely around the iiange g' in the depression G when the parts are assembled, while the smaller opening h3 is large enough to permit the' thimble tobe rotated around the square spindle .D. Notches h4 are made in the thimbles, adapted toqreceive a suitable tool for rotating them.` Y 1 I I indicate roses,lin this instance of circular forni, from the external surface of each of'which projects a neck I. A cylindrical "extension-I2 is 'for'rned integrally with each roseon its innerside, in which extension is a bore z', threaded to engage the body h. The

'diameter of the extension I2 is the same as :that ofthe Hange hof the thimble H, the extension having cut thereon athread of similar pitch that it may enter the depression G, Y A sleeve J, flanged atj, passes through and beyond an axial opening inthe rose I and neck I", a knob K being iixedto the projecting portion of the sleeve. In assembling these parts the sleeve. .I is passed through the rose I until the iiangej Valouts against thev shoulder t2 at the base of the bore t.

The knob K, having been put on the projecting end of the sleeve and moved inwardly until it reaches the neck I', apin, screw, or other fastening is employed to secure the knob in position. A square hole extends through the sleeve J, through which the Asquare spindle D may slide independently` in an axial direction.

In practice a hole is bored through the door of a size sufficient to admit the cylindrical extensions I2, and the lock is lnortised in as usual. The thmbles H are then inserted in the circular opening and their flanges h screwed into the depressions G. AroseI then follows on each side of thedoor, lthe cylindrical extensions I2 of said roses entering the circular opening .at yopposite ends, and on turning each rose the threaded bore t will engage the threaded body portion of the thin1- ble H on its side of the door. Continued r0- tation of the roses will cause them to bear firmly against the respective sides of the door. A screw L, passed through a hole in each rose and into the door, prevents backward rotation of the rose. The spindle D may be inserted in the lock immediately after placing it in the door or before the last rose is put in place.

From Figs. l and 2 it will be seen that Whatever the thickness of door within certain normal limits no difficulty will be experiencedinattachingmyimprovement. Should the door be thin, as in Fig. 2, the extensions I2 will follow the thimbles H into the depressions G. In athick door if only a few threads ot' each part are engagedl the knobs will be sufciently held.

An important feature of my invention consists in the application of the thimble H between the rose and the lock. By its use a double telescopic joint is produced, giving a wider range of adjustment than would be possible if the extensions I2 were screwed directly int-o the lock.

Vhere but one knob is required, the hole for the projection I2 is made in one side of the door only and a plug H', similar to the one seen in Fig. 7, substituted for the thimble H in the unused depression G.

It is to be understood that the word rose found in t-he claims is intended to cover any means for rotating the cylindrical eXtension I2.

I do not restrict myself to the exact details of construction, combination, and arrangement herein set forth, it being obvious that minor variations thereof not involving the exercise of invention may be made by the skilled mechanic, and such departures from what is herein described and claimed not involving invention I consider as within the scope and terms of my claims.

Having thus described my invention, I claim- 1. In combination, a lock-casing having a threaded depression in its side, a rose provided with an integral extension having a threaded bore and adapted under certain conditions to enter said depression in the lockcasing, and a threaded thimble connecting said depression with said extension, substantially as set forth.

2. In combination, a lock-casing provided with a threaded depression in its side, a rose having an inwardly-projecting cylindrical extension with a threaded bore and being also circumferentially threaded to adapt said eX- tension to engage under certain conditions the said threaded depression, and a threaded thimble connecting said depression With said extension, substantially as set forth.

3. In combination, a lock-casing having a threaded depression in its side, a cylindrical extension projecting inwardly from a rose, having a threaded bore and being circumferentially threaded, and a threaded thimble of greater diameter at one end than at the other, and adapted to connect said depression with said cylindrical extension, substantially as set forth.

4. In combination, a lock-casing having a threaded depression in its side, a rose provided with an extension having a threaded bore, a thimble having two diameters for connecting said casing with said extension, a sleeve passing through the rose and adapted to rotate therein, and a knob or handle secured to the sleeve, substantially as set forth.

5. In combination, a lock-casing having a threaded depression in its side, a rose having a cylindrical extension projecting inwardly and provided with a threaded bore, a thimble, having a greater diameter at one end than at the other, vfor connecting the casing with the rose, a polygonally-bored sleeve passing through the rose and adapted to rotate therein, a knob or handle secured to the sleeve, and a spindle, polygonal in cross-section, adapted to slide in the sleeve, substantially as set forth.

6. In combination with a lock-casing and its cover-plate, each having a threaded depression Gr formed with a flanged axial opening g, a hub or stump for operating a latch, said hub being journaled in the flanged openings g, substantially as set forth.

7. In combination in a lock, a casing and its cover-plate, each having a threaded depression formed therein, two thimbles, each being of greater diameter at one end than the other and adapted to engage each with one of said depressions, a rose on each side of the lock provided with a cylindrical extension having a threaded bore to engage the thimble on the same side of the lock, a sleeve passing through each rose and adapted to rotate therein, a knob or handle secured to each sleeve, and a polygonal spindle adapted to slide in a similarly-shaped bore in each sleeve, substantially as set forth.

In testimony whereof I hereunto set my hand and seal.

WILLIAM S. BARTIIOLOMEW.
