MCCLINTOOK YOUNG, OF FREDERICK, MARYLAND.

BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent No. 423,508, dated March 18, 1890. Application filed May 21, 1889. Serial No. 311,672. (No model.)

To all whom it may concern:

Be it known that I, McOLINTooK YOUNG, of Frederick, in the county of Frederick and State of Maryland, have invented certain Improvements in Brush-Machines, of which the following is a specification.

My invention relates to a machine adapted to receive a perforated brush-block and a mass of bristles and metal fastening devices, divide the bristles into tufts, double the tufts, and drive the tufts and their fastening devices'to their places in the body automatically.

Figure 1 is a front elevation of my machine with the parts in their normal positions. Fig. 2 is a side elevation of the same. Fig. 2 is a section on line 16 16' of Fig. 2, showing the manner in which the slides are mounted one Fig.3 is a' front elevation of the principal parts of the machine, the operating cam and lever being omitted and the parts shown in the position which they occupy in an intermediate stage of the operation.

Fig. 12 is a vertical cross: section through the same on the line 6 6 of Fig. 13 is a perspective view of the needles employed in separating and transferring the bristles. Figs. 14 and 15 are detail views showing the successive steps in the operation of forming and inserting the tufts, the parts being viewed in side elevation. Figs. 16' and 17 arecross-sections through the tuft inserting and securing devices in different positions. Figs. 18 and 19 are vertical crosssections through the bristle-carrying devices and tuft inserting and securing devices in different positions.

My machine is intended for use in the man ufacture of brushes which have the bristles or other fibers divided into tufts, and the tufts bent or doubled at the middle and inserted into holes in a stock or body.

Certain parts of the machine are adapted for use in forming and inserting the tufts irre-' spective of the manner in which they are secured in place. Other portions of the machine are particularly adapted for securing the tufts in place by means of metal fastening-strips inserted through a row of tufts and provided with teeth or projections which extend down into the holes for the purpose of keeping the tufts in place, as described and shown in my application for Letters Patent, Serial No.

287,380, filed October 6, 1888, to which referonce may be made for a more detailed descrip tion of the brush.

In order that the construction and operation of my machine may bethe more clearly understood, I will before describing the ma chine direct attention to Figs. 15 and 17, showing the construction of the brush. In these figures, X represents a brush block or part way therethroughin rows.

Y Y represent the tufts, formed of fibers body having-a series of tuft-holes a; bored folded or doubled atthekmiddle and inserted to present the successive rows of holes in position to be filled; second, a reservoir for bristles or other fibers, combined with devices by which the fibers are removed from the mass in suitable layers or slices and the layers presented in position above the brush-block;

third, mechanism by which the layer of bristles is divided into tufts,the tuft folded over and around the metallic fastening-strips, and the strips and tufts finally driven downward to their places in the brush or body.

B represents the bed or table to sustain the brush-blocks, one at a time, in position to receive the tufts. It is grooved in its upper face to receive and guide the block, and proand hold the same snugly in place.

b but advanced by an incline Z2 on the edge vided wit-h lips I) to hold the block down in place, while allowing it to slide endwise. A spring b, fastened to one side of the table, as shown in detail in Fig. 4, acts on an eccentric or block W, seated in the side of the table, so as to bear on the edge of the block Thetablestands normally in a horizontal position, so that the tufts will enter the block vertically; but in certain classes of brushes the tufts at the ends are seated in inclined holes, and to permit their insertion the table is connected to the main frame by a horizontal pivot 5 so that it may be tipped or inclined endw'ise. A slidingpin b mount-ed in the'underp'art of the table, may be engaged in either one of a series of holes 11 infthe frame to keep the table in position.

The brush-block is advanced step by step on the table bya dog I), pivoted to the upper end of a'lever b pivoted in turn to the frame at its middle and having at'its lower end a stud The dog and lever are retracted by spring of cam-plate D, which acts against the stud b During its advance the dog engages directly with the brush-block, entering the holes therein and carrying it forward the required distance. During its retreat the'dog slides freely over the block, after which it remains at rest. Thecam-plate, which has other important functions. hereinafter explained, is

sustained on the mainframe by a horizontal journal 01, and is'provided with a hand-lever d by which it is vibrated. The lever is provided with a weight d to counterbalance the cam-plate.

The above are all the parts necessary to sustain and advance the brush-blocks.

Passing now to the mechanism for presenting the bristles above the brush-block, attention is directed principally to Figs. 1 to 12. The bristles or fibers 6, cut to a uniform length, are laid horizontally in quantity in a.

. lower end of the magazine is normally closed,

.and the mass of bristles sustained therein, as

shown in Figs. 2, 3, 7, and 12, by one end of an underlying arm f, formed on .a casting F,

. mounted on a horizontal pivot f, so that it may be tipped to the left in order that the zine, as shown in Fig.9.

arm f may be carried from under the magazine to a horizontal positionover and across the brush-block, as shown in Fig. 3. The arm fis intended to receive a layer or, slice of bristles and carry the same from the magazine to the position over the brush-block, where the slice is subdivided into tufts, and the latter driven down into the block. The separation of the slice or layer of bristles from the mass, and the confinement of the slice upon the arm fis secured by two blades G and H. The upper blade G is attached to a slide 9, moving in a grooved guide 9' on the main" frame, so that when the slide is advanced the blade is thrust through and across 1 the magazine and the mass of bristles therein parallel with the face of arm f at a distance of a-quarter of an inch more or less therefrom, as shown in Fig. '8, thus separating the slice or layer between the blade 'and arm from the mass above. The secondary blade H is carried by a slide h, moving in a groove in arm f, as shown in Figs. 3, 4, and

5 and is arranged to fit within the main blade G, asshown in Figs. 11' and 12, so that the two blades advance as one through the mass of bristles. arm f swinging to the left carries with it the blade H, as shown in Figs. 9 and 10. The blade 11 acts at this time to hold the slice or separated bristles down in position on the car-- After they have advanced, the

rier-arm f, while the blade G, remaining atrest, sustains the mass of bristles in the 1n aga.

The blade G receives its reciprocation through .a roller g on g in the cam-plate D. The blade l-I receives its reciprocating motion from the blade G,

through :a stud on the latter engaging in a cavity h in the former. .Although these parts are disconnected when arm f swings forward, the connection is re-established when the arm f returns preparatory to the retraction of the blades. Accidental motion of the blade H is prevented by a friction-spring 72 fastened torarm f, as Fig. 12.

, The swinging moti ;n of arm f is secured by a roller f on casting F, extending into a.

slot f, in the cam-plate 1). When the camplate is swung upward or forward by its lever (1', the slot 9 acting on roller 9 causes the two blades to be thrust through the mass of bristles. As soon as they complete their TOO its side extending into a suitably-shaped slot motion, the roller 9 reaches a part ofthe slot which is so curved that the advance of the blades ceases. 4

During the above action the roller f receives no motion from the slot f but at the next movement said slot' acts to swing the .casting F and its arm f forward until the may descend upon the arm preparatoryto the removal of the next slice.

pivoted to the main frame and provided atv its lower end with a'stud 2*, arranged in the path of cam-plate D. A spring i acting on the lever, urges the feed-dog upward when the parts are released, but when cam-plate D descends to return carrier-arm f to the magazine it actuates lever 11 and causes the follower to press the bristles down.

Passing now to the mechanism for dividing the slice of bristles on .arm f into tufts, and seating the latter in the brush-block, attention is directed chiefly to'Figs. 1, 2, 3, and 14. to 19. That the other parts may be understood, it is first to be noted. that the bristles lie transversely of the arm fthat is to say, in

I n the direction of the length of the brush-block.

It is also to be noted that the blade H, overlying the bristles, has a longitudinal vertical slot h therein, and that the arm f contains a corresponding. slot f beneath the bristles, as shown in Figs. 11, 12, and 18, to admit of the bristles being driven down therethrough.

On the main frame, directly above the table, is mounted a vertical slide J, to which there is firmlyattached a blade j, having its lower edge provided with a groove j to receive and retain the upper edge of the metal tuft-fastening strip 2, as shown in'Figs. 10 and 14, 16, l7,.&c. A spring-finger j is attached to the blade to rest upon and assist in retaining the fastening-strip; but this finger may be omitted provided the strips are slightly sprung or bent to-cause them to bind in the groove.

To the face of the slide J there is attached by suitable guides j?" (see more particularly Fig. 2*) a second plate K, having an independent vertical motion. this independent plate is formed with pointed teeth It, designed'topass down through the slice of bristles and separate the same into tufts. Aspring It tends to force the plate K downward beyond the blade j, but a link k connects the plate with a lever k pivoted on the slide J, and arranged to encounter a fixed projection on the frame, so that when the slide approaches its uppermost position the toothed plate is raised above the end of the blade, as in Figs. 2 and 3. This permits the fastenings to be readily inserted in the exposed end of the blade. a d

When the slide is lowered, the toothed end of the plate descends beyond the blade and the teethpass down through the blade H and arm f, and the bristles held thereby, separating the bristles, as shown in Fig. let and in dotted lines in Fig. 10, into tufts. The de The lower end of scent of'the toothed platecon tinues until it acts to double or fold the tufts and carry them down'through'the slot in arm f, as in Fig. 19, and finally comes to a rest with its teeth resting in the brush-block betweenthe tuft holes, as in Fig. 15. While the tufts are being doubled or folded the blade J' commences its descent and carries the fastening-strip down within the fold or bight of the tufts, and, continuing its descent after the plate Kis at rest, itcauses the fastener to carry the tufts down between the guiding-teeth into the holes in the block, where they are followed and secured by the teeth of the fastener, as shown in Figs. 16 and 17.

It will be perceived that the toothed blade serves the dual purpose of separating the tufts, and of guiding them in their descent after the separation, and that the plate j serves not only to present the fastener, within the tufts, but to carry both the fastener and the tufts home totheir places in the block.

The slide may be actuated by any suitable means, but I commonly connect it by link f to acrank-arm on shaft j whichisseatedin bearings in the frame and hand-lever The fastening-strips may be inserted in the insertingblade j by hand, but in order that the attendant may feed them more easilyto the machine I provide a guide L, grooved horizontally in its face to admit of the strips being slipped therein. It is fixed to the frame in such position that its groove registers with that in the elevated blade. A slide Z is mounted in theguide and connected by link .1 with arm f, so that when the latter swings toward the magazine it advances the slide,

and vice versa.

When arm f is down, the attendant lays a fastener into the guide in advance of the slide, andwhen arm f swings back, the slide forces the fastener endwise to its place in the blade-j. p

In operating the machine the brush-block is placed on the table, the magazine filled with bristles, and a fastener placed in the blade j. The hand-lever'd' being then raised,

the cam-plate D first thrusts the blades G H through the bristles and then swings the arm 1 f and blade H down until the bristles overlie the holes which are to receive hem. The

second lever 7' being-thus actuated causes plate 'K to descend and separate the slice into tufts and the tufts to double down provided wit-h 'a through arm). This action -is followed by the descent of the blade and fastener and the driving of the fastener and tufts into the block. The lever j is then returned to i ts first position, thereby elevating the blade and the toothed plate. A new fastener is nowin-- serted in the thereby restoring the arm f to the magazine,

delivering the fastener to its blade, retract-' ing the dividing-blades, and actuating both the block and bristle-feeding devices.

In order to prevent the spreadingor openguide and lever, d depressed,

ing of the folded tufts as theypass from the slot in arm f to the block, the arm is provided on the under side and on opposite sides of its slot with two plates f and f, the former fixed and the latter hinged and urged toward its companion by spring f I'have described and illustrated my ma chine in the form which I have found best adapted for general use, but it is to'be understood that the details may be modified as desired, provided the general mode of action remains the same.

As regards the bristle-separating devices,

the essential features arethe co-operating blades and the movable arm acting in connection with one of the blades to transfer the separated bristles from the magazine to a position opposite the brush-block, and it is manifest that the-means for sustaining and moving said parts are not of the essence of the invention.

As regards the mechanism for dividing the bristles into tufts and inserting the tufts and fasteners, the essential elements are the toothed plate and the independently-moving blade combined with a slotted bristle-support. The skilled mechanic will at once perceive that their forms may be modified, and that they may be sustained and actuated by various devices, the equivalents of those herein shown.

In order that the outer end of the blade G may be supported and prevented from sagging under the weight of the bristles in the reservoir when the blade is in an operative position thereunder, I provide the arm 1,

which is attached to the side of the reservoir and extends outward and downward therefrom. This arm is provided near its end with an opening r formed to permit the passage of the blade and is further provided below this opening with afoot r in position to support the end of the blade. v

I do not claim herein the combination of the toothed blade for separating the bristles into tufts with a second blade acting directly upon the tufts to force them to their seats, the same being the subject-matter of an application of even date herewith, Serial No. 311,571.
