Specification of Letters Patent.
Patented Sept. 5, 1911.
Application filed November 21, 1910. Serial No. 593,465.
To all whom it may concern:
Be it known that I, FREDERICK BRUNE, a citizen of the United States, resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Conductor-Hooks, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification. This invention relates to improvements in conductor hooks which are particularly adapted for use in fastening pipes to a support.
One of the objects of this invention is to provide a conductor hook formed of sheet metal and which is light in weight and strong and durable and inexpensive to manufacture.
A further object of this invention is to form a sheet metal conductor hook of a sin gle integral piece of metal and to provide said hook with a strong shoulder whereby it may be easily driven into a support.
With the above, and other objects in view,
the invention consists of the conductor hook and its parts and combinations as set forth in the claims, and all equivalents thereof.
In the accompanying drawing in which the same reference characters indicate the so isame parts in the several views: Figure 1 indicates a side View of the conductor hook; Fig. 2 is an edge view thereof; Fig. 3 is a transverse sectional view on a large scale of the conductor hook taken on line 3-3 of Fig. 1; Fig. 4: is a view of the sheet metal blank from which the conductor hook is formed; Fig. 5 is a perspective view of the blank after it has been bent transversely into a U-shaped form; and Fig. 6 is a perspective view of the blank after it has been again operated upon and bent, transversely, into an inverted T-shaped form, which operation precedes the final operation of bending the outer end of the blank, longitudinally, into a semi-circular shape to form the hook portion as shown in Fig. 1.
Referring to the drawing the numeral 8 indicates the complete conductor hook which consists of the hook or semi-circular conducltor-tube-engaging outer portion 9, the driving shoulder or projection 10 and the pointed end or support engaging portion 11.
In forming the conductor hook a sheet metal blank is cut to proper shape to form the hook portion 9, the shoulder portions 10 and the pointed end 11, and the blank is then bent medially, longitudinally, into a U- shaped form as shown in Fig. 5. The upwardly extending side portions of the blank are then bent laterally toward and against each other and partly over the base portion to the form shown in Figs. 3 and 6. The operation just described, forms the blank, transversely, into an inverted T-shaped form with the stem portions tapering from the shoulder projections toward both ends, respectively, of the partly formed blank.
The outer end portion 9 of the blank is then bent into semi-circular shape with the base portion of the inverted T forming the inner periphery of the semicircle to form the hook portion of the conductor hook. The support engaging end 12 of the hook may be sharpened by a punching operation or by grinding if desired so that it may be easily forced into a support.
In forming the conductor hook of sheet metal, the adjacent edges of the hook will engage each other while the other portions of the sheet metal will be spaced a slight distance apart to form approximately a tubular conductor hook with the ends of the tube closed by the converging walls of the sheet metal.
In use the hook is placed alongside of a conductor pipe with the semi-circular portion extending over the pipe. The pointed end of the hook is then driven into the support by pounding against the shouldered projection until the semi-circular portion tightly embraces the conductor pipe and the pipe will then be securely held in position against its support.
In driving the hook into a support formed of wood, and across the grain of the wood, the fiber of the wood will be forced inwardly at a slight angle in the direction the hook is driven and any outward strain or pull on the hook will tend to straighten the fiber and slightly compress the walls of the hook toward each other and wedge the hook in the wood so that it cannot be withdrawn. The shouldered projection provides for easily driving the hook as the shoulder extends at right angles to and is in a direct line with the pointed end of the hook.
The T-shape-in-cross-section-shape and tubular form of the hook provides a very strong construction which is well adapted to withstand strain in any direction to which it may be subjected while in use.
From the foregoing description it will be seen that the conductor hook is strong and durable and very simple in construction and is inexpensive to manufacture.
l/Vhat I claim as my invention is:
As a neW article of manufacture, an integral tubular sheet metal conductor hook having a semicircular tube-engaging outer from one end of the hook to the other, a portion of the stem of the pointed end portion being elongated to form the projecting driving shoulder of the hook and which extends approximately at right angles With relation to the support-engaging-portion.
In testimony whereof I afiix my signature, in presence of two Witnesses.
FREDERICK BRUNE.
