UNITED STATES PATENT OFFICE.
IMPROVEMENT IN ATTACHING KNOBS TO SPINDLES.
Specification forming part of Letters Patent No. 101,808-, dated April 12, 1870.
To all lwhom it may concern:
Be it known that I, MATHEW ANDREW, of Melbourne, Victoria, have invented a new and useful Improvement in Door-Knobs; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the'accoinpanying drawings, forming part ot this specitication, in whichv Figure l represents a sectional side elevation ot' this invention. Fig. 2 is a transverse section thereof.
Similar letters indicate corresponding parte.
This invention relates toan improvementin that class of door-knobs which are fastened on their spindles by a spring-catch and ratchetteeth, so that the distance between the two knobs can be readily adjusted to correspond to the thickness ofthe door to which they are to be attached.
My invention consists in the arrangement of a spring-catch extending beyond the side of the spindle, in combination with a hole extending through the slIa/nk of the knob and situated at the side of the spindle, in such a manner that by inserting a brad-awl or other like instrument into the hole in the knob the spring can be forced back and the knob released, while the spindle retains its full strength.
In the drawings. the letter A designates a door-knob, made of an y'suitable material, and provided with a socket to receive the spindle B. One side of this spindle is provided with a series of ratchet-teeth, a, and in the socket ofthe knob is formed a chamber, b, to receive the spring-catch c. It' the spindle is pushed into its socket, this spring-catch engages with the ratchet-teeth and retains said spindle, the ratchet-teeth being so formed that they slide over the catch when the spindle is pushed in; but they do not allow of the spindle' being withdrawn. In order to release the spindle the spring-catch has to be pressed back, and to effeet this purpose-I make `the spring-catch so `that it projects over one side of the spindle,
and in the shank of the knob I produce a hole, d, which passes down at the side of the spindle opposite the projecting portion ot' the springcatch. (Best seen in Fig. 2 oi' the drawings.) By inserting a brad-awl or other similar instrument into this hole the spring-catch can be readily pressed back and the spindle released.
I am aware that a spindle provided withl ratchet-teeth as a means for securing the same in the knob has already been used; but in all cases of this kind known to lne the spindle is provided with a slot, thongh which the instrunient for disengaging passes, and 'by such slot the construction ot' the spindle is rendered extremely difficult, and, furthermore, the spindle is weakened, so that it is liable to be wrenched of'in a short time.
By my invention I am enabled to dispense with the slotin the spindle, so that said spindle can be easily made, and that it retains its full strength.
I do not claim, broadly, as myinvention the arrangement of ratchet-teeth and a catch for the purpose of fastenipg door-knobs on their spindles; but,
Having thus, fully described my invention, what I claiin as new, and desire to secure by Letters Patent, is-
The at spring G, attached to the knob-spindle and adapted to engage with the ratchetteeth a a, and extended beyond the side ofthe spindle B, in combination with the extended chamber b and the opening d in the shank of the knob A, substantially as and for the purpose set l'orth.
