FLY-BRUSH.

SPECIFICATION forming part of Letters Patent No. 236,928, dated January 25, 1881.

Application filed July 29, 1880. (No model.)

and exact description of the invention, such 'as 'will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in fly-brushes; and it consists in providing each one of the rods to which the brushes are attached with a counterweight at its upper end, whereby the brush is made to operate more easily.

It further consists in making a slot through the supporting arm in which the brush is held, and providing the rod with needle-points for pivots, which pivots have their hearing in set-screwswhich are passed through the side of the arm.

It furtherconsists inthe arrangement and combination of parts, which will be more fully described hereinafter, whereby a very cheap, simple, and effective fiy-brush is produced.

The object of our invention is to produce a fly-brush which can be raised and lowered and attached to a table or placed beside a bed, and in which the brushes are operated by a clock-work or other suitable motive power, so that its action will be automatic.

Figure 1 is aside elevation of our invention, partly in section. Fig. 2 is a vertical section through the supporting-arm. Fig. 3

is a plan view of the supporting-arm. Fig. 4

shows an extension placed on the arm for the purpose of operatingtwo brushes at once. Fig. 5 is an endview of the operating mechanism.

A represents a suitable hollow stand, which is provided with suitable supporting-legs B. Passing down through the top of this hollow stand A is the supporting standard or rodO, which can be vertically adjusted for the purpose of raising or lowering the brushes, and held in any desired position by means of the set-screw N. This standard A can be attached to the edge of a table by means of a set-screw, or can be placed beside a bed or any other object from which it is desired to drive away the flies.

Secured to the top of the supporting-standard O is a'suitable arm, M, which has a case, E, containing the operating mechanism, secured upon its top. This operating mechanism consists of three or more wheels, which are operated by means of a spring, and the last one of the series of wheels meshes with an endless screw which has a crank, H, secured to its outer end, and which projects through the side of the case. To this crank is secured a connecting-rod, L, which unites the crank to the rod 0, which is pivoted in the arm M, and has the brushRsecured toits lower end. This rod R passes through the slot S that is made in the arm M, and is provided with needle-points which form the pivots upon which the rod rocks. Passed through the sides of the arm are suitable adjustingscrews X, which have their ends recessed so as to receive the ends of the pivot of the rod,

and by means of which screws all wear can be taken up at any time. Attached to the upper end of this rod 0 is a suitable adjustable counter-weight, Y, which causes the rod 0 to operate much more easily.

When it is desired to operate more than one brush at a time-as, for instance, when the table is of considerable lengthan additional arm, V, which has a slide secured to its inner end to fit over the outer end of the arm M, is used. This arm V having been adjusted into position, and carrying a second rod, 0, is then united to the first rod by means of a wire, rod, or'other suitable connecting device, and then when the first rod is put in motion, by means of the spring mechanism, the secondrod and brush will be operated at the same time. The number of rods used, of course, can be increased to any desired extent.

By making a hollow stand, as here shown, to support the entire operating mechanism, the brushes can be adjusted up and down at will, and the brush can be moved around so as to be used in any part of the house, and is a great improvement over all those brushes which have to be suspended from the ceiling, and hence can only be used in one place.

Having thus described our invention, we

5 claim- 1. The combination of the hollow standard A, provided with legs B, with the adjustable standard 0, and operating mechanism E, a supporting-arm M, and the brush-rod 0, the

10 parts being arranged to operate substantially as described.

2. The arm M, secured to the top of the adjustable standard 0, and having the slot S made through it, in combination with the rod 15 0, provided with needle-point pivots, and the adjusting set-screws for supporting the rod, substantially as shown and described.
