BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 724,371, dated March Application filed May 24,1902. Serial N 108,857. (No model:)

To all whom it may concern:

Be it known that I, EDWARD F. ABBEY, of Toledo, in the county of. Lucas, State of Ohio, have invented certain new and useful Improvements in Brush Machines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in machinery used in the formation of brushes, and especially in machinery used in the formation of brushes having what are known as solid backs-that is to say, in which holes are drilled in a brush-block at the proper distances apart and at the proper angles for the reception of the bristles, and the bristles are subsequently inserted in said holes and held by means of metallic retainers-although, as will presently appear, the invention made the subject-matter of this application is capable of a much wider range of usefulness and may be employed to advantage in connection with any desired type of machine wherein the brush-block may be positioned automatically, either for the insertion of the bristles or for the formation of the holes for the reception of the bristles.

The invention consists, therefore, primarily in an improved mechanism for automatically positioning the brush-block. The invention further consists in certain novel details of construction and combina: tions and arrangements of parts, all as will hereinafter be described, and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure 1 is a side elevation of a machine embodying my present improvements, portions of the frame and mechanism being shown in section and broken away to disclose under- Fig. 2 is a top plan view of a brush-block carrier. Fig. 3 is 'a front elevation of the same, showing the upper end of the adjusting-shaft. tional view showing a portion-of the mechanism for turning the adjacent shaft on its longitudinal axis. Fig. 5 is a perspective view showing details of the mechanism for controlling the horizontal adjustment of the block-carrier. r

Fig. 4 is a detail sec-v Like letters of reference in the several fig ures indicate the same parts.

In illustrating my present invention I have shown it in connection with a machine for insertingbristles or tufts into the brush-block, the type of machine illustrated being one now in extensive public use and known as the Gane filling-machine. This type of ma chine is well illustrated in United States Let ters Patent No. 378,130, granted to J. V. Gane February 21, 1888; but it will be understood that the invention may be used in connection with any other desired type of machine,

either for inserting the bristles or having a drill or drills for forming the holes into which the bristles are inserted.

-In the Gane machine illustrated the letters A and A indicate the main frame of the machine, in which all of theworking parts are mounted; B, the inserter; C, the inserteroperating lever; D, the adjustable bristlesupport; E, the reciprocatory base for the block-carrier, and F F the mechanism for reciprocating said base from the main shafts G and G.

, In this machine the block has heretofore been positioned by hand, so as to present its face in proper position and at the proper angle for the insertion of the bristles; but in accordance with my present invention I now propose to position the block automatically by an improved mechanism, thereby relieving the operator of this labor and insuring a presentation of the block at a mathematicallycorrectangle and in correct position to insure thevbristles 1n the completed brush being held in proper relation to each other and to the block-back. To accomplish this desirable end, the block or brush-back is held in a carrier mounted on suitable centers having axes at substantially right angles to each other and capable of an adjustment to vary the radius or are described by the block or back, with a controlling mechanism operating through a single connection and i embodying pattern disks or cams, which will so move the controlling mechanism as to properly position the block. In said drawings the block-carrier is indicated by the letter H and preferably consists of a rectangular frame having suitable clamps h mounted to slide therein andadjustable toward and fromoeach other by means of a screw-shaft H having right and left threads thereon and controlled by a rearwardly-extending arms or rods I, adjustably mounted in trunnions r1, taking pivotal hearings in a transverse head or frame K, the arrangement being such that the carrier, with'its block, is free to swing vertically with its block on the trunnions t'. The head or frame K is provided with a central rearwardly-extending stem 70, adjustably mount ed in a trunnion L, which latter pivots in a bearing L, formed or mounted on the forward end of the reciprocatory base or slide E, before referred to. The axis of the trunnion L is at right angles to the axis of the trunnion t, and by adjusting the stems or rods I or it in their trunnions it is obvious that the curvature of thearc or arcs described by the face of the carrier or block mounted therein may be varied at will, and inasmuch as in practically all brushes the curvature of the are on the longer diameter of the face of the brush is less than the curvature on the shorter diameter the trunnion L is located some distance'in the rear of the trunnions t, and in the particular embodiment illustrated in the drawings the longest diameter of the brush, block will be substantially horizontal, al-

I though it is obvious that this is an arbitrary neetion between the track or way being arrangement and is not a necessary incident to the present invention.

The control or adjustment of the carrier H is secured through the medium of a verticallymovable and horizontallyrotatable shaft M, having at its upper end a crank M, provided with a track or way m, pivotally mounted thereon and extending horizontally or in the line of reciprocatory movement of the carrier H. This track or way m is adapted to cooperate with or receive a block N, mounted on the carrier H, so as to be capable of sliding on the track or way, the conpreferably formed by dovetailing one into the other, so as to hold the carrier and shaft M against independent vertical movement, as will be understood from an inspection of Fig. 3 of the drawings. The block N is adjustably connected with the carrier H, the adjustable connection shown being a conventional one, consisting of angle-irons N secured to the carrier by set-screws N passing through slots N in the angle-irons, so as to accommodate blocks of different thickness or to increase or diminish the distance between the rows of holes on the face of the block, thereby permitting of the making of larger or smaller brushes with the same pattern-disk,

vertically the carrier H will be swung on the trunnions 't', and if said shaft be rotated it will, through the crank M and track,as aforesaid, swing the carrier H horizontally on the trunnion L, and in any of its positions of adjustment the said carrier H is free to recipro cate horizontally. Thus it is only necessary to provide a means whereby the shaft M may be given the desired movements to accurately position the brush-block for the operation of the cooperating member. To secure these movements of the shaft M and carrier H, I provide a pair of pattern disks or cams P P, Fig. 1, journaled on a center 19 and adapted to be rotated intermittently by means of a worm p, a pawl and ratchet p and a driving-camp", mounted on the main shaft G and operating througha connection 10 (the end of which surrounds the cam, so as to provide contacting-surfaces therefor) to operate the worm and pattern-disks at the proper time, or' when the carrier H and inserter B or equivalent cooperating members are retracted from the operative position. Resting on the pattern-disk P is the forward end of an arm R, pivotally supported on a shaft R and adapted at its forward end to directly support the shaft M. Thus as the disk P is retated the shaftM will be raised or lowered, in accordance with the contour outlines of the disk P. A second arm S, eorrespondingto the arm R, rests on the pattern-disk P, this arm S being also pivotally supported on the shaft R and at its forward end is connected by a link 8 with a bell-crank lever S, pivoted on a portion of.the main frame. The opposite arm of the bell-crank lever S is pivotally connected by a link T with a lever T, the axis of which is formed by the shaft M, but the support for which is formed by a bracket S on the main frame. The outer end of this lever T embraces a rod U, which is connected with the shaft M, so as to form a crank,whieh when the lever T is oscillated or moved on its axis will rotate the shaft M to a corresponding degree. The connection between the lever T and crank U is preferably formed by a ball-bearing U, which will permit the crank or rod U and shaft M, which is jour naled in the bracket S on the main frame, to move vertically without obstruction, but will hold said shaft M accurately in its angular position of adjustment, dependent upon the position of the lever T as controlled, by the pattern-disk P. In mechanism of this character it is desirable that the arms or parts controlling the position of the carrier II should be lifted out of contact with the pattern disk or disks during the feeding movement or rotation of the disks,- and this is especially desirable where sharp changes in the contour outlines ofv the disks occur and where, as in the present instance, it is foundcarriers V carry pawls W, adaptedto engage the ratchet-wheels V V whenever the carriers V are moved rear-wardly by the cam V and when so moved to lift the arms R and S out of contact with the pattern-disks. The cam V operates just in advance of the cam 9 which rotates the pattern-disks. 0am V is so constructed that it allows the pawls W to move forwardly far enough to insure the lowering of arms R and S on the patterndisks P P, so as to position the carrier H accurately at each operation. The controlling-springs X are adjustable on the rods V in position to engage the rear ends of the pawls W and hold them from again engaging the ratchets V V on the rearward motion until they have passed the desired number of teeth to overcome the irregularities of the pattern-disks P P. I 7

To secure a wide range of adjustment, the link V may be adjustably connected with the lever V as shown in Fig. 1, and,-further more, the link T, Fig. 4, is also preferably adjustably secured to the lever T, as illustrated clearly in Fig. 4, by a set-screw T whereby the distance between the holes in a row may be varied for large or small brushes while using the same pattern-disk.

With the mechanism thus described itwill be seen that absolutely accurate and uniform results may be secured in the completed brushes and what is of greater importance the entire operation so far as the positioning of the brush-block is concerned is automatically accomplished. As in said Gane; machine, in order to start the mechanism the operator places his foot on the treadle Z and depresses the same; but inasmuch as in the present embodiment it is desirable that the machine should be automatically stopped when the pattern-disks have made a complete revolu-' tion a stop mechanism ispreferably introduced, which will be controlled by the pattern-disks on their shaft. Obviously any wellknown or preferred stop mechanism maybe employed, and I have shown a conventional mechanism consisting of a catch Z, held forward by a spring in position to catch and hold the treadle depressed when once pushed down by the operator, and this catch is adapted to, be automatically released, so as to allow the treadle to rise and stop the mechanism, by means of a projection Z (shown in Fig. 1) on the shaft 19. The projection Z pushes downwardly on a rod Z and through a bell-crank Z and rod Z releases the catch Z when the pattern-disks have made a complete revolution.
