MPROVEMENT IN DOOR-SPRING.
'The Schedule referred to in these Letters Patent and making part of the same.
vmandrel or core, and one of the spiral springs,which actuaie the door-closing lever.
Figure 3 is a sectional view of the box, or cap, in Which-one end of the door-closing lever operates.
Figure@ is a view of the sliding plate, hereinafter referred to.
The nature of my invention consists in the peculiar'v constructionA and' operation o f the door-closing lever, thepeculiar manner of attaching the springsthereto, the peculiar construction .of the springs themselves, and the peculiar arrangement of the device for holding the door or gute open when desired.
'Io enable those skilled in the art to which my invention appertains, to make and use the same, I will proceed to describe its construction and operation.
In the drawings- 4 y A represents a lever, er arm', which may be made of either cast or malleable iron, the small end of which slides Ona plate, B, inside oi' a box, or cap, G.-
The cap C is screwed tothe door, or gate, by means of lugs c, and prevents anydisplacement of the small end of the arm.
The sliding plate B is formed with projections, b, which fit in corresponding cavities in the lugs c, by which means the plate is heldfirmly iii place.
The large end of the arm A terminates in a nearly circular form,with an annule r groove, g, neach side, surrounding an opening, through which passes aicore or mandrel, M, around which are spiral springs S.
The inner end ofthe wire composing the spring S, is bent at a right angle, so as to form a tenon, T, corresponding in form with a mortise, R,'in the annular groove g Instead ofthe mortise R, there may be projections,
with which the tenon T may engage.
- The outer end of the wire composing the spring S projects tangentially from the coil, a suiiicient length to engage with a base-plate,P, which furnishes a bearing-surface for said tangential end.
The base-plate P is riveted to the bottom of the casing I), which is screwed to the side of the door.l jamb or gate-post. v
Near the large en d of the arm A, is a hook, H, formed in one piece with the arm.
The casing I) has cast on it a lug, e, to which is attached a link, L, which engages with the hook H, and holds the door or gate open when desired.
When in position for use, the springs S are arranged upon the core, or mandrel, M, one on each side of the large end of the arm A, the tenon T vbeing inserted in the mortise R, the inner end of the spring S resting in the annular groove g/,thetaugential end K bearing on the base-plate P, and the outer endof the spring S.
resting against the outer end of the casing D.
This peculiar arrangement has a tendency to prevent any lateral or vibrating motion of the springs, and to force them secm'ely to their seats in the annular grooves.
I do not coniine myself to the use of wire in the construction of my springs, noito the peculiar mannerl above described for attaching them'to the arm. The large endof the arm may be formed with projections on each side, to which the inner ends of the springs y may be attached, and the springs themselves may be volute springs, constructed of strap-steel.
Having thus described my invention,` g
What I claim as new, and desire to secure by Letters Patent, is
1. The arm A, constructed of cast or malleable iron, Vwith the annular recesses y, hook H, and mortises R, or theirequivalents, for attaching the springs, substantially as shown and described.
2. The combination of the tangential end K, baseplate l?, tenen T, and`mortise It, on the arm A, substantiallyas shown and described.
3. The 4sliding plate B, in combination with the cap C, constructed and operating substantially as set forth, and forthe purpose specified.
4. The combination of the link L and hook: H, sub-- stantially as show-n, and for the purpose specified.
5. The casing D, when constructed with the lug e cast thereon, in combination with the link L, hook H, and arni A, substantially as shown, and for the pur pose specified.
6.- rIhe combination of the arm A, springs S, inandiel M, and casing I), constructed and operating as herein shown and described.
