IMPROVEMENT IN ADJUSIING KNOBS T0 SPINDLES..
dlp rlgihule nimmt tu invites): @titten tsnt :un making gaat nt 11p aims.
T0 ALL WH'VOMIT MAY CONGERNa Bc it known that I, ALFRED DAWES, of Hudson, in the county of Middlesex, and Commonwealth Massachusetts, have invented certain newand useful Improvements in the Adjustment of Door-Knobs upon their Spindles; and I do declare thefollowing to be the full, clear, andexact description of the construction and operation of the same,vreference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is a vertical longitudinal section. ot' the knobs and spindle, as adjusted to a door.
Figure 2 is a transverse vertical section ofthe shank of' theknob B through the line a a, ofg. 1, showing the knob.
Figure 3 is a like section of the shank ofthe knob B. through the line bb of tig. 1, also showing the knob B.
A. represents the'door; B B, the knobs; C, the spindle; D, the square, and E the sexagonal end of C; F, the slots or grooves in the ends of the spindle; G, the shank of the knob screwing upon D; H, the shank of the knob screwing upon E; I, the set-screws. v p
My invention consists in certain improvements in the construction of that class of knobs and spindles made to screw the one upon the other, by which the knobs are made fast upon the spindles at any desired point, and can be fitted to doors of any thickness. I cut the threads of the screw of different degrees of iincness on the two ends of thei'spindle, say the one making twelve turns to one inch, and theother fifteen turns to one inch.r These screw-threads should extend about as far as the spindle is intended to lproject through the door on each side, and should be out in the corners, and not extend far into the sides or faces ofthe spindle. The knob must have feuiale screws, cut with corresponding threads, each to receive its -end of the spindle. One end of the spindle I make 'a little larger than the other, and out it with five', six, or more sides, instead of four, and extending as far along the spindle as the knob is intended to reach. AThe other part of thespindle 'is made square,
the same as those now in use. In each face ofthe spindle, at each end, and as far as the screw-threads extend, or nearly as far, I cut a groove. Inthe shank of each knob, and at right angles to the spindle-hole, I cnt two or three screw-holes, extending down to the said spindle-hole, and located relatively to each other lin the circumference of the shank, as follows that is to say, the second one hundred and thirty-five degrees, or threeeighths of the circumference of the shank,`from the first; the third two hundred and forty-seven and one-half degrees, or, eleven-sixteenths of the circumference from the l'rst. I have adopted these distances as the most practicable, though I do not confine myselfto any specific degree of distance.'
l The operation of-these devices is this: When the Iknobs are applied to the door, and oneof them brought to about its proper position, it must be turned upon its spindle until-one of the holes in the shank is brought opposite to one'of the grooves in the spindle, and a small screw (in the drawings) driven through said hole until its point enters-said groove. The other knob must then be screwed upon the spindle until both knobsure made l to set 'closely upon the surfaces ot' the door, but not so tight as, by their friction, to prevent the action of the catch-spring. If,/when both knobs are brought into the exact position, it is found that neither of the holes in the last knob coincides with a groove in the spindle, then, by turning backward one and forward the other knob, u. point will be attained on the spindle when both knobs will fit the door exactly, and one or the other ofthe holes in each shank will coincide with one of.' the grooves in each end of the spindle. The diicrences in the threads of the screws, and the number of grooves on the two ends of the spindle, and the positions of the lioles in the shanksv of the knobs, enable me to place the knobs and make them fast at any distance from each other, and, consequentiy` to exactly t doors of any,thickness.
I do not nd it necessary or best, in all cases, to use all these devices, but in knobs designed for doors where great exactness is demanded, I adopt them all. In other cases, the different screw-threads and two or three holes, or even one, in the shank of one of the knobs, enables me to bring the knobs into u position suiciently close to the door for all practical purposes. Indeed, sometimes two holes in the shank of one of the knobs, with the same screw-threads at each end Aot' the spindle, will be sufficient, even when both ends of the spindle are of the same size, and square, or when. one of the knobs is made fast upon its end ofthe spindle. The grooves may be dispensed with by cutting the points ofthe hold-fast screws square oil` and driving them-full against the flat faces ofthe spindles, but I do not think the knobs remain so firm-or so long in place.
Having described my improvement, I claim, and wish to secure by Letters Patent, tbe following:
1 Knobs and spindles, screwing the oneV into the other by screw-threads of different degrees'ot tineness on the two ends.
2. In the shank of floor-knobs that screw upon their spindles, the making two or more screw-holes for the reception of the set-screws, so placed in the circumference that no two nre opposite, :it the same time, to the faces ofthe spindle.
3. The making one end of the spindle, for doorknobs, with :L diierent number of sides from tbe other.
4. The combination of door-knobs and spindles, screwing the one upon the other, with the spindle having a different number of sides, and screw-threads of different degrees of fineness in the two ends, and having one7 two, or more screw-holes in the shank of tbe knobs to receive the hold-fast screws; all for the purposes and in the manner substantially as described.
ALFRED DAWES.
