WILLIAM B. SHORLAND, OF MANCHESTER, ENGLAND.

KNOB ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 250,588, dated December 6, 1881.

Application filed May 7, 1881. (Model.) Patented in England J nne 24, 1880, in Belgium December 22, 1880, in France December 22, 1880, and in Germany December 29,3880.

To all whom it may concern:

Be it known that I, WILLIAM B. SHORLAND, a citizen of Great Britain, residing at Manchester, in the Kingdom of Great Britain, have invented certain new and useful Improvements in Knob Attachments; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a longitudinal central section,

showing door-knobs and spindle having present invention. Fig. 2 is a plan view of one part or half of the spindle; Fig. 3, detail in cross-section, line a; m, Fig. 2 5 Fig. 4, plan view of the boss; Fig. 5, plan view of the rose; Fig. 6. central cross-section of Fig. 5 on line y 3 Fig. 7 shows the binder-wire; Fig. 8, perspective view of the two parts of the spindle ad justed ready to be matched together for use, knobs shown in dotted lines.

' This invention relates to improvements in that class of; knob attachments designed more especially to enable the knobs to be fitted upon doors, drawers, or other devices of any usual or ordinary thickness; and the novelty in the present instance consists in the detail of the construction and adjustment of the several parts, whereby, in an easy, neat, simple, and most efficient way, all the desired results are accomplished, as will now be more fully and in detail set out and explained.

In the accompanying drawings, A denotes any usual door or similar knob, made of metal, porcelain, or other material or substance, and B the spindle. This spindle, when used for doors, is made in two pieces, I) I), each generally like the other and having a rib, b, at the inner end, where it fits into the shank of the knob and a forked opening, 11 The faces at each part of the spindle may be roughened, grooved, or fluted, as shown at b, and one may have a groove, b, at the edge. When, now, the said two parts of the spindle are placed the one on the other to be used in a door or like device the rib b on the end of the one fits into the opening I) in the other, and the two parts can have space vfor considerable longitudinal movement back or forth on each other, while by this said detail of construction and matching together the parts, when made of the right length and fixed together-as when in place in the knobs A and secured by screws 0, passing through the shank of the boss and the spindlewill be as firm, rigid, and strong as if they constituted a single piece. This screw cit will usually be found best to pass entirely through the spindle and into the opposite side of the knob. It may be found best to have the head of this screw 0 press upon the fork part of the spindle. While the abutting faces of the two parts of the spindle may be smooth if desired, it is preferred to have them roughened, as above described, to prevent their easily moving on each other, and also to permit the use of a binder in shape of the bent wire 76, one portion of which is thrust between the two parts of the spindle in any of the grooves, where they match, and the other rests in the longitudinal groove b. In placing the knobs in position the boss Z, of metal preferably, having the spindle through its central opening, I, is screwed or otherwise fixed to the face of the door or other article, and holes I are provided for this purpose. The projections m of the rose m are adapted to match with and pass through the openings l in the boss I, and thus the rose will be held firm when the parts are fixed in place as in use. One side of the boss projects into the shank of the knob, which is recessed, as shown in Fig. 1, and keeps the spindle from wearing the door or drawing the works of the lock, and also prevents the knob from shaking.

The method of applying this device to doors and for like uses will be readily understood. They are taken, as shown in Fig. 8, and passed through the door and lock, one from either side, and when pressed up close the screws 0 in the knobs are tightly screwed up, except when the wire 70 is used. Then one screw is fastened and one knob is taken off to draw the spindle out to put the wire in and then put back again.

To adapt this invention to cupboards, drawers, &c., where only one knob is used, a single spindle is fixed in the shank of the knob and fastened by the screw 0, while in the slot in the other end of the spindle will be fixed the turnbutton or finger O. In use this button comes on the inside of the cupboard door or drawer.

Having thus described my invention, What I consider new, and desire to secure by Letters Patent, is-

1. In a door-knob attachment, a spindle, B, made of two parts, b b, each having a boss, I), at one end, and a slot, 1), at the other, substantially as and for the purposes described.

2. In adoor-kuob attachment, the boss l, havin g screw-holes at the ends, a central spindleopening, and others at the sides, combined with rose m, having projection m, substantially as described.

3. In a door-knob attachment, the binder K, in combination with the parts I) b of the spindie B, transversely grooved in their abutting faces at b and longitudinally grooved at b, the whole adapted together and operating substantially in the manner set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM BURROW SHORLAND.
