ADJUSTABLE SUPPORT FOR ELECTRIC SWITCHES.
Specification of Letters Patent.
Patented Aug. 20, 1918.
Application filed February 18, 1916. Serial No. 79,200.
To all whom it may. concern:
Be it known that I, EDWARD H. KRUSE, a citizen of the.United States of America, and resident of Fort Wa no, in the county of Allen and State of In iana, have invented certain new and useful Improvements in Adjustable Supports for Electric Switches, of which the following is a specification.
This invention relates to improvements in adjustable supports for electric switches and the object thereof is to provide an appliance that will afford a' substantial support for electrical switches, electrical lamp sockets, and electrical fixtures in the walls and ceilings of buildings, the especial feature being the adjustable base and the bar for attaching the same to the studding and joist of the building, and the means for securlng the base upon the bar in the desired location.
The objects of the invention are accomplished by the construction illustrated in the accompanying drawings in which Figure l is an elevation showing the apparatus secured to the studding of a building, the bar being broken away in several places; and i Fig. 2 is a view projected from Fig. 1 showing the apparatus in a plane at right angles thereto and with the studding in section.
Similar characters of reference indicate corresponding parts in both views and referring now to the same:
(A) is a bar having bent ends (B) adapted to lie flat against the opposite faces of the studding (C) and to be secured thereto by means of nails (D). The adjustable base (E) is in the form of an open frame of sheet metal with two extending slotted arms (F) through which the bar (A) extends, the base being normally movable thereupon. The base proper has also two oppositely disposed projections (G) respectively coincident with the juncture of the arms (F) with the base proper, and a series of threaded openings (H) are made in each projection adapted for the insertion of a screw (K). The frame has also other inwardly projecting ears (L) having threaded perforations (M) therein and situated at points equally distant from the projections (-G).
The bar (A) extends through the slotted arms (F) and the latter are of such length that the face of the base (E) with which the arms are connected will extend in a plane beyond the outer edge of the bar (A) sufficiently to equal the thickness of lathing and the several coats of plastering (not shown) that is usually supported by the studding or joist. The bar (A) is secured in place with its outer edge flush with the outer faces of the studding or joist, or is secured a distance inward therefrom if necessary to compensate for variations, contem plated in the thickness of lathing and plastering.
In using the invention the'bar is set between the studding and its ends secured thereto in such position as will admit of the base being shifted to the desired location.
When the base is so located the screws (K) are tightened against the bar which has the efiect of holding the base in place during-the completion of the lathing and plastering operations. The screws K.) may then'be removed and used in the same openings or in the other openings (H) for securing a lamp socket, switch or fixture stud to the base. The auxiliary threaded perforations (M) are intended for the insertion of additional screws for supporting more securely the usual fixturestud and appurtenances.
The arrangement of the two series of threaded openings (11) with different radii facilitates securing switches, sockets, etc., of
varying sizes.
What I claim is:
1. In a device of the class. described, a supporting bar; an open frame having slotted arms extending from its periphery and through which the bar loosely extends, the frame having inwardly extending projections, each projection having a. series of threaded openings therein, the center opening of which is in the same plane as the bar; and a screw engaging in the center opening of each projection adapted to bear against the bar and hold the frame inadjusted to [engage the bar and hold the former in 10 position. i adjusted position. I
2. In a device of the class described, a In testimony whereof I aflix my signature, a frame having numerin presenoeof two Witnesses.
suppoyting bar; EDWARD H KR-USE 5 ous threaded perforations extending therethroug'h; slotted arms slidably mounted Witnesses: 4 upon the bar and supporting the frame; and MATILDA METTLER,
means in connection with the frame adapted MARIE A. HARTMAN. Copies 0! this patent may be obtained for five cents each, by addressing the Commissioner of .Patents,
- Washington, D. 0."
