JOHN E. GAITLEY, OF TROY, NElV YORK.
DOO R-KNOB.
SPECIFICATION forming part of Letters Patent No. 443,223, dated December 23, 1890.
I Application filed December 14, 1889. Serial No. 333,773. (No model.)
To aZZ whom, it may concern:
Be it known that I, JOHN E. GAITLEY, a citizen of ,the, United States, residing at Troy, county of Rensselaer, and State of New York, have invented certain new and useful Improvements in Door-Knobs, of which the following is a specification.
My invention relates to such improvements; and it consists of the novel construction and combination of parts hereinafter described and subsequently claimed.
Reference in ay be had to the accompanying drawings and the letters of reference marked thereon, which forin a part of this specification.
Similar letters refer to similar parts in the several figures therein.
This invention relates to oertain'improvements in stove-door knobs, and more particularly to an improvement upon the construction of my former patent, No. 30%,925, dated September 9, 1884.
The object of the invention is to provide an improved stove-door knob exceedingly cheap, strong, simple, and durable in construction and composed of a minimum number of parts, and whereby the use of a screwt-hreaded bolt and its securing-nut are obviated, and hence the knob when once secured in position cannot work loose or rattle, and whereby the knob will be well ventilated, and hence kept cool, so that it can be handled on operating the door. These objects are accomplished by, and this invention consists in, certain novel features of construction and in combinations of parts more fully described hereinafter, and particularly pointed out in the claims.
Referring to the accompanying drawings, Figure 1 is an elevation of the knob secured in position, showing part of a stove-door. Fig. 2 is a section taken in the plane of line 03 00, Fig. 1. Fig. 3 is a detail elevation of the knob and its spindle. Fig. a is an inside elevation of a portion of the stove-door, showing the inner end of the knob-spindle locked in its retaining-slots. Fig. 5 is an exterior elevation of a portion of the stove-door, showing the spindle-receiving slot, the knob being detached.
In the drawings, the reference-letter B indicates a stove-door provided with the oblong transverse slot 13, surrounded on the inner side of the door by a boss provided with grooves or recesses B B extending laterally from each long side of the slot. The outer side of the door can be provided with an outwardly-projecting annular flange 0 around said slot, tapered on its inner side to form a seat. This seat can be cast with the door, as shown, or can be separate therefrom, as shown by dotted lines.
A indicates the knob-head, of suitable exterior form and contour and provided with the spindle A, rigid therewith, and at its outer end provided with a T-head integral therewith, or with one or more lateral lugs A integral with such spindle. The inner face of the knob-head around the spindle is annularly concaved or provided with an annular groove or recess A, forming a seat for the outer large end of the heavy open coiled expansive spring I), embracing the knob-spindle, and at its inner end fitting in the seat 0 at the stove-door. This spring preferably tapers inwardly toward the door, as shown.
To attach the knob to the door the spindle is passed through coil D and the spindle-head passed through slot B, the opposite ends of the spring being seated in their respective seats. The spring is then compressed by forcing the spindle through said slot until the lateral proj ections pass completely through such recess and is secured by giving the spindle a quarterturn, so that said proj ections will swing around and spring into the recesses 13 where they will be held by the spring. This spring is so formed as to length and strength and the reccsses B so formed as to depth that the spindle projections are securely locked in the recesses by the resilient force of the spring.
\Vhen desired, the knob can be detached by pushing in on the knob against the tension of the spring until the lateral projections are forced out of their recesses and then giving the spindle a lateral turn, so that said projections will register with the slot B and the spindle can be withdrawn.
A door-knob is thus constructed which can be made and sold separately from the stove and can be easily and quickly attached to any slotted door and securely held thereon without the use of nuts and bolts or anyother part or piece which can work loose. Of course it is obvious that one lateral projection A of the spindle fitting in one lateral recess B would hold the parts looked under ordinary conditions, that the spindle and knob-head can be cast in one piece or made separately and the spindle inserted in the knob-head, and that the wire coil 1) may be given any desired cross-sectional contour.
What I claim isl. The combination of the knob having an annular groove or seat in its inner face, the spindle rigid with the said head and having the T-head integral with its outer end, the tapering coil-sprin g surrounding the spindle with its large end resting in said groove, and a small cup-shaped seat through which the spindle passes for the inner end of said spring, substantially as described.
2. In combination, the knob having the an nular groove or seat in its inner face, the spindle rigid with the said knob and having a lateral arm at its outer end, the stove-door having a transverse narrow slot surrounded by a boss at the inner end, provided with a recess extending radially across the slot to receive said lateral arm, the tapering coilspring surrounding said spindle and resting at one end in said seat of the knob, and a seat for its inner end.
3. The combination of the stove-door having a transverse slot having one or more lat eral recesses from its inner end, the seat integral with the door at the outer end of said slot, the door-knob having the seat in its inner face, the spindle rigid with said knob and having one or more lateral arms at its outer end for the purpose set forth, and the spring around the spindle resting in said seats at its opposite ends, respectively, substantially as described.
In testimony whereof I have hereunto set my hand this 12th day of December, 188.).
JOHN E. GAITLEY.
