A HUTTGER SPRING COUNTERBALANCED SASH 2 Sheets-Sheet 1 Original Filed June 28, l1954 sept. 3, 1935.
A. HUTTGER SPRING COUNTERBALANCED sAsH 2 sheets-sheet 2 original Fild June 28, 1934 FIGJZ Patented Sept. 8, 1936 UNITED STATES kPATENT OFFICE SPRING COUNTERBALANCED SASH August Huttger,` Tioga, Pa., assignor to Edward P. Huttger, Philadelphia, Pa.
2 Claims.
This invention relates to spring counterbalanced sash in which a torsional spring or springs, is or are, put under strain when the sash is closed and when opened exert force upon connected mechanism to aid the opening operation, and hold the sash in the desired position.
Specifically the instant case is a division of my copending application for patent filed June 28, 1934, under Serial Number 732,891, on Metal window frame and sash construction, and it has for its primary object the provision of a novel spring counterbalahce assembly whereby the associated sash is more easily operated than heretofore.
Another object is to provide a spring counterbalance for metal window frame and sash which is of a very durable construction while positively stabilized in action under all normal conditions.
With the stated and ancillary objects in view as will hereinafter become apparent, or be specifically referred to, this invention consists in the features of construction, combination and arrangements of parts, all as particularly set forth and more specifically defined in the claims.
In the drawings:
Fig. I is a broken partial-elevation of a metal window frame and sash construction embodying the spring counterbalance of the present invention, looking from the inside outwards and with the frame jamb in lateral section to better disclose the counterbalance mechanism.
Fig. II is a Vertical section taken on the plane designated II-II in Fig. I.
Fig. III is a broken and enlarged detail section of the upper sash operating mechanism.
Fig. IV is a fragmentary perspective View of a top corner of the upper sash with a portion of the associated operating rack.
Fig. V is a sectional view corresponding in the main with Fig. III, but illustrating a modied form of the operating-spring stabilizing means.
Fig. VI is a somewhat similar View of a further type of spring stabilizer.
Fig. VII is a perspective view of a stepped bracket, hereinafter fully described.
Fig. VIII is a perspective view of a sleeve-like member, later on described in detail; and,
Fig. IX is a perspective View of a composite gear, also hereinafter fully explained.
Like characters of reference are applied to corresponding parts in all the views.
Referring first and with more particularity to Figs. I and II, and also in part to Figs. III and V,
Which show portions of a window frame and sash construction in accordance with the prior application for patent, hereinbefore referred to and of which the instant case is a division, the reference numerals I, 2 respectively designate the upper and lower sash of a sheet metal Window structure; 3 indicates the left-hand frame jamb-box; 4 the head, and 5 the sill; all of which are preferably constructed in accordance with the noted prior application.
The means for operatively controlling the respective sashes I, 2 and which constitute the subject-matter of the instant case comprise a stepped bracket 6, one of which is attached within each frame jamb-box 3, as by screw-bolts l, Figs. I-IV; the left-hand side of the window only being shown as the right-hand side is a counterpart thereof, and in order to avoid unnecessary descriptive matter. This bracket 6 is formed with a bearing 8 for a pin or axis 9, on which is freely journaled an integral, or composite, spur gear I and mit-er-pinion I I; the former of which meshes with the associated upper and lower sash rack I2, as best understandable from Fig. II. The respective miter-pinions II, on the other hand, mesh with corresponding pinions I3 integral with the lower ends of sleeve-like members I4, freely supported on a vertical extension I forming a part of each associated stepped bracket 6. Each sleeve-like member I4 is prevented from vertical, or axial, displacement by means of a headed pin I6, fitted into an axial boring I'I of the upstanding bracket extension I5, and a diametric cotter pin I8, as best shown in Fig. III; while diametrically-opposed holes I9 are provided in the sleeve members I4 for ease in assembling or disassembling said parts.
Each sleeve-like member I4 is provided near its upper end with a lateral flange 2D and a vertically-directed annular portion 2|, both concentric with the axis thereof, and jointly affording bearing for a thin tube 22, functional as a stabilizer for a torsional spring 23; said spring having its lower extremity 24 passed through a suitable hole 25 in the lateral ange 20. The tube 22 extends coaxially of the spring 23, and its upper portion slidingly cooperates with an inverted cup 26 securely attached, as by a rivet 21 to the horizontal portion 28 of the window frame head 4, while the torsional spring 23 has its upper extremity passed through a hole 29 therein. and clinched over at 30, in an obvious manner. Thus it will be readily seen that each tube 22 functions as a floating-support or centralizingstabilizer to retain the associated spring 23 in correct operating alignment.
Instead of the tube 22 being slidably-tted internally of the associated spring 23, as shown in Figs. I, II and III, it may be oatingly-supported intermediate the sleeve member annular portion 2| and the inverted cup member 2S, as indicated in Fig. V; or, it may be similarly supported by the sleeve member lateral flange 2Q, and located outside the spring 23, as indicated in Fig. VI, when so requisitioned or deemed advisable.
From the foregoing description and drawings the operation of my improved spring counterbalance for metal sash will be self-evident to those acquainted with the art, Without detailed explanation herein.
It will likewise be apparent from the preceding disclosure that the invention is well calculated to adequately fulfil the objects preliminarily stated; while it is to be further understood that changes and variations may be effected within the spirit and scope of the following claims and so far as the prior art prescribes.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, isz- 1. In a device of the class described, the combination of a bracket adapted to be attached to the window frame, said bracket having an extension thereon, a rack on the sash, a sleeve rotatable on the extension, a headed pin having axial engagement in the sleeve, means for interlocking the pin with the sleeve to prevent rela- .tive axial movement thereof, said sleeve having a lateral fla-nge, a cup member xed to the head of the window frame, a tube movable relative to the cup member at its upper end and engageable with the -sleeve at its lower end, a spring having one terminal fixed to the window frame `and its other terminal fixed to the said iiange, .said tube Aserving to retain the spring in axial alignment at all times, and a geared connection between said rack and sleeve.
2. A device as claimed in claim 1, wherein the means for interlocking the headed p-in with the extension consists .of a pin engaged .in the extension and headed pin.
AUGUST HUTTGER.
