DRAFT SLIDE OR REGISTER.
SPECIFICATION forming part of Letters Patent No. 319,367, dated June 2,1885.
Application filed October 18, 1883. (No model.)
To all whom it may concern:
Be it known that I, LEONARD A. WHITE, of Taunton, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Draft Slides or Registers, of which the following is a specification.
This invention relates to improvements in slides for regulating the passage of air, such as the draft-slides of stoves, ranges, and furnaces, registers, and the like.
This invention consists in the combination, with the slide and its actuating-knob, of a slotted spring adapted to keep the slide tight against its seat and to form a surface on which the knob can be moved more easily than on the east-iron surface on which it has heretofore been moved.
In the accompanying drawings, Figures 1 and 3 are front elevations of my improved draft-slide as applied to stove-doors, showing two Ways of arranging the spring, and Fig. 2 is a longitudinal section through Fig. 1.
A is the door of a stove or furnace or the plate of a register, and is provided with openin gs a for the passage of air.
B is the slide, by moving which the open ings a may be uncovered or covered, as desired.
The slide B is actuated by means of the knob O, the stem 0 of which passes through a slot in the plate A and connects the knob C with the slide B.
A'spring, D,of plate metal, is placed between the knob O and the plate A. It is also provided with a slot, through which the stem 0 of the knob Gpasses. The spriugD is retained in position with its slot coinciding with the slotin the plate A by means of its ends being turned down over the edges of two bars extending across the central opening, as clearly shown in Fig. 2.
The tension of the spring D is adjusted to preserve the desired fitof the slide B on its seat by screwing the stem 0 into the knob O or into the slide B. The springacts on the under side of the knob C, and, being smooth,affords a better surface than the ordinary stove-castings for the knob to slide upon.
Instead of a single plate-spring with a slot in it, two parallel plate-springs may of course be used, the space between them forming the slot.
I am aware that in registers and air-drafts the slide has beenheld by springs; but in all cases known to me the spring moves with the slide and its actuating knob, and I am not aware that the spring has ever before been attached to the plate so as to remain stationary and provide a smooth surface for the knob to slide upon.
I claim as my invention The combination of the plate A, having openings (1, the slide B, for covering or uncovering the openings at, the knob (l,for actuating the slide B, its stem 0 passing through a slit in the plate A, and the spring D, attached to the plate A, slotted to receive the stem 0 of the knob O and bearing against the knob O,whereby the slide is held against the plate and a smooth bearing is provided for the knob to slide upon, substantially as hereinbefore set forth.
