Patented Jan. 13, 1942 UNTED STATES PATE ortica 1 Claim.
The present invention relates to brushes and more particularly to a spring steel wire type of brush and has for its primary object to provide a brush of this character which will not clog up.
Another object of the invention is to provide a spring steel wire brush which will be selfsimple in construction and which may be inanufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following detailed description, taken in connection with the accompanying drawing, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a side elevational view of a device embodying my invention.
Figure 2 is a bottom plan view of the invention.
Figure 3 is a longitudinal sectional View taken substantially on the line 3-3 of Figure 2.
Figure 4 is a transverse sectional view of the invention.
Referring now to the drawing in detail, it will be seen that the reference numeral 5 designates an elongated block like head, constructed from wood or any other suitable material. The opposite side edges of the head 5 are grooved as at B to provide means for securely gripping the same in the hand when using the brush.
The bristle portion of the brush is formed from a length of at sided spring steel rod which is bent to form a multi-sided coil 'l which is secured to the side 8 of the head 5 by means of a plate 9.
The plate 9 has formed therein a series of grooves or channels Il] which extend transverse the plate and are provided to receive in each a coil Il of the spiral rod 1. Spurs I2 are punched or stamped from the plate 9 and are utilized' as anchoring means to secure the plate 9 to the head 5 with portions of the coil 'l in the grooves l0 to securely hold the coil 'l attached to the head 5.
When the brush is in use it is moved in either direction in alignment with its longitudinal axis. Due to the resiliency of the coils Il the brush can be used equally as eifectively on a curved surface as on a flat surface.
Although I have shown and described herein a preferred embodiment of my invention it is to be definitely understood that any change or changes may be made in the structure and arrangement of the several parts within the spirit of the invention as claimed.`
What is claimed is:
As an article of manufacture, a brush embodying a head, a plate engaging one side ofthe head and provided at intervals with struck-out prongs embedded in the head for securing the plate in substantial facial contact with said one side of the head, said plate having pressed therefrom a series of parallel grooves disposed obliquely with respect to the longitudinal dimensions of the plate, and a single length of wire wound in a rectangular shape having the respective opposite ends thereof engaging in the endmost grooves at the respective opposite ends of the plate, with intermediate convolutes respectively having one section thereof engaging in an intermediate groove and conned therein by reason of the plate at the open sides of said grooves being secured in facial contact with said side of the brush head.
