BRUSH-MACHINE.

SPECIFICATION forming part of Letters Patent No.l 243,528, dated June 28, 1881,

Application filed May 5, 1881.

Z'o all whom it may concern Be it known that I, JAMES H. DoDDs, of Portsmouth, in the Province of Ontario and Dominion of Canada, have invented certain new and useful Improvements in Machines for Making Brushes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the artto which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part ofthis specification.

Thisinvention relates to machines for making brushes, or, more properly, for boring the previously-prepared brush-blocks, and dividing, drawing, and tying the bristles; and it consists in certain improvements in the construction ofthe same, which will be hereinafter more fully described, and in which- Figure l` is a perspective view of my improved machine. Fig. 2 is a side view. Fig. Sis a top view. Fig. 4 is a longitudinal sectional view through the main shaft and levers on the line x x, Fig. 3. Fig. 5 is a longitudinal sectional view through the box on the line y y, Fig. 3. Fig. 6 is a front view. Fig. 7 is a vertical transverse sectional view through the box on the line z z, Fig. 3. Fig. 8 is a detail view of the shuttle and holder. Fig. 9 isadetail view of the tilting table and mechanism for operating the same, and Fig. 10 is a detail view of the ratchet block-feeding mechanism.

Corresponding parts in the several figures are denoted by like letters of reference.

In the drawings hereto annexed, A represents a platform or table,supported upon suitable legs or uprights, B B, and provided at its front end with a hinged or tilting table, C, to support the brush-block.

`Pivoted to the under side, near the front end of the tiltingtable C, is a curved or segmental rod or lever, D, carrying at its extreme end a friction roller, E, working in an eccentric groove, F, in a wheel or disk, G, journaled to the side of the frame, and provided with a crank or handle, H.

It will be seen that by operating the disk Gr the tilting table C, with the brush-block supported thereon, may be adjusted to any de- (Model.)

sired angle at which the perforatons are to be made and the bristles to be inserted.

A standard, I, mounted upon the frame A, is provided with suitable bearings for the main shaft J, having pulleys K L for the transmission of powerfrom anysuitable source. Shaft i J is provided with an eccentric,M, from which motion is communicated through rods N N, connected by a frame, 0, encompassing the said eccentric, to levers P Q, located, respectively, above and below the frame, which is provided with suitable fulcrums or bearings for said levers.

To the front end of lever P is journaled a vertical shaft or spindle, B, to which a rotary motion is imparted by means of a pinion, S, fitted upon said spindle, and having a key, T, traveling in a vertical groove, U,therein. Motion 'is imparted to said pinion by a bevel- Wheel, V, xed upon a shaft, W, suitably mounted, and having a pinion, X, engaging a gear-wheel, Y, upon the main shaft. The shaft or spindle R carries a bit, Z, for boring the brush-block, which is meanwhile supported upon the tilting table.

The lever Qcarries at its front end a block, A', in which is secured the needle B', to which a vertical reciprocating motion is thusy imparted. Y

A bracket, C', projecting laterally from the standard I is provided with a vertical pin or pivot, D', for an arm orlever, E', havinga pivoted connecting-rod, F', extendin g through an opening, G', in the side of the standard,.so as to be operated by a cam or eccentric, H', fixed upon the main shaft, thus giving a horizontal reciprocating motion to the lever E'. front end of the latter is curved or bent in a downward direction, and provided with a carrier or holder, I', for the shuttle J'. The shuttle is provided on one side, as shown, with a hinged lid or door for the admission of the bristles, as will be hereinafter described. Brackets K' at' the front end of standard I form a way or race for the shuttle.

L' is a'box or hopper, secured upon the front The` end of the standard I, to contain the bristles which are to bemade upintobrushcs. Said box i IOC weights or followers, O','are to be placed, to force the bristles in a downward direction against the feeder. The construction and arrangement of thelatter is asfollows: The slanting bottom P' of the hopper L'is provided with arms Q', adjusted between suitable guidestrips, R', upon the sides of the box, to which the bottom is thus attached in such a manner as to be capable of being withdrawn a certain distance. The upper side of the bottom is provided with a groove, R2, to receive the sliding feeder S', which has upon its upper side two or more pointed strips or rows ot' teeth, T', which serve to push or feed the bristles from the bottoms of the several compartments down toward the bottom of the box or hopper. Upon its under side the bottom P' is provided with a dovetailed groove, U', in which is fitted a slide, V', moving vertically. The upper end of said slide is provided with a recess, W', to receive a second slide, X', which isheld in position by a plate, Y', secured upon the front or under side of the bottom P', as shown. Z' Z2 are what I term the ,dividers,27 consisting of rods pivoted at their upper ends to the slide X', and provided at their lower ends with inturned teeth A2. B2 is a bracket secured upon the front side of slide V', and provided with two pivoted arms, G2, extending` diagonally in opposite directions, and provided with slots D2, working over studs E2 upon the faces of the dividers. The arms C2 are provided with pivoted lugs F2, having threaded openings G2, to receive the ends ot' a double-threaded screw, H2, journaled in the bracket B2, and having a square seat, 12, for a key or wrench, by which it may be turned so as to adjust the slotted arms C2, and consequently the throw of the dividers.

J2 is a spring secured upon the upper side of plate Y', and rounded or beveled at its upper end, as shown. The spring J2 is provided with a stud, K2, vpassing through a perforation, L2, in plate Y', and adapted to iit in a recess, M2, in the slide X'. The slide V' is provided at its upper end with a shank, N2, having a beveled or inclined front side, which, when the said slide is moved in a downward direction, strikes the upper rounded end of the fiat spring J2, forcing it in an outward direction, and thus releasing the slide X', which has until then remained stationary. The result ot' this operation is that, first, the ends of the dividers (which are pivoted to the slide X') are brought toward each other, so as to separate from the bristles forced down by the feeder a suitable quantity to be pushed down into the shuttle; second, the slide V' moves down, carrying with it the slide X', and consequently the dividers, which push the bristles down into the shuttle, as will be hereinafter described.

The box or hopperL' is provided with double or false sides M2, adjustable by means of setscrews N3, Working in the outer sides, so as to accommodate bristles of any desired length. By means of the double screw H2 mentioned above the throw of the ends of the dividers may be regulated for the same purpose.

To operate the feeding mechanism 1 avail myself of a lever, O2, fulcrumed at P2 to a bracket extending upward from the box or hopper. The rear end of lever O2 is provided with a slot, O3, traveling` upon a pin or stud, R2, at the front end of lever P, by means of which the said lever O2 isthus operated. The front part of lever O2, or as much of it as is in front of the fulcrum, is curved and provided with a slide, S2, adjustable by means ot` a setscrew, T2. t

U2 is a cross-piece, pivoted transversely in suitable bearings upon the upper front end of the hopper, and provided with a forward projecting arm, V2, connected with the slide S2 by means of a pivoted rod, W2. 'lhejnnction of arm V2 and rod W2 is connected by a pivoted rod, X2, with the upper end of the feeder S', to which a vertical reciprocating motion is thus imparted, the extent of which is regulated by adjusting the slide S2 upon the lever O2. The T-piece U2V2 is employed simply to steady the motion and enable the adjustment to take place. The extreme outer end of lever O2 is connected by a rod or pitman, Y2, with the shank N2 of slide V', which latter is thus operated with the result above describedthe throw 2 of said slide being, of course, longer than that of the feeder.

Z3 is a rod arranged in suitable slides upon the side of standard I, and provided at itsV rear end with an arm, A3, working inl a camgrooved disk, B3, xed upon the main shaft, by means of which a longitudinal reciprocating motion is thus imparted to the said rod' Z3. The front end of thclatter is forked, as shown, the arms or prongs G3 being passed by the sides of the box or hopper L' and attached to the sides of the movable bottom P'.

D3 D3 are arms or levers pivoted to the sides of the box or hopper, and having their upper ends pivoted to arms C3, and their lower ends provided with points E3, and connected by a cross-piece, F3. By this mechanism the movable bottom is, on the upstroke of the feeder, moved in an outward direction, so as to enable the feeder-teeth to pass the bristles, while on the downstroke the bottom is moved back, thus forcing the teeth into the bristles, so as to carry the latter down to the point where they are separated by the dividers, which, the stroke of slide V' being, as above stated, longer than that of the feeder, carry the bunch of bristles down under the cross-piece F3. In the meantime the shuttle has been moved back by its operating mechanism, and the pointed ends of the levers D3 serve to open its lid and that of the carrier, thus enabling the bunch of bristles to be forced by the dividers into the shuttle.

When the bottom moves back and the feeder and slide V' up the shuttle moves forward, and its lid and that of the carrier are closed by the pointed levers D3. By regulating the throw of the feeder the size of the bunch of bristles quired.

To the under side of the front end of the frame or platform A is secured a tube, G3,for the accommodation of the needle carrier or block A', said tube being provided with a slot,

H2, for the end of lever Q. l3 is aslide adjusted under the latter and supported upon a coiled spring, J3, the tension of which may by regulated by a set-screw, K3, at the bottom ofthe tube. A l1ook,'L3, swiveled upon the lower end of tube G3, or in any other suitable position, carries the reel M4, upon which the wire used for sewing or tying the bristles is wound. In threading the machine the wire is first passed between the slide I3 and theend of lever Q, andv then upward and through the eye of the needle. It follows that on the downstroke of lever Q the wire is stretched and clamped between the end of said lever and the slide, thus preventing displacement.

A box or casing. N4, secured to thefrontend of the standard I is provided with a suitableg perforation or bearing for the rod or shank O4, which is capable of sliding vertically, and is forced in--a downward direction by a suitablyarranged coiled spring, P2, the tension of which may be regulated by a set-screw, Q3. The shank 04 is provided with a stud, R3. projecting forward through a vertical slot, S3, in the box or case, adjoining which is pivoted a cam, T3, provided with a thumb-piece, U3, by which it may be operated to raise or lift the shank. The latter is curved at its lower end and provided with a stud, V3, upon which is pivoted a ratchet-wheel, W3, and a bracket, X3, having a spring-pawl, Y, for operating the said ratchet-wheel. The bracket X3 is provided with a forward-projecting plate, Z4, having a perforation, A4, to receive the lower end of a lever, B4, fulcrumed in a tube, C4, swiveled in a slide, D4, which latter'is adjustable by asetscrew, E4, in a vertical slot, F4, formed in a bracket, G4, extending forward from the front end of standard I, as shown.

Connected to the front end of lever P (or to the rear end of lever 02) by means of a pivoted rod, H4, is a plate, H5, sliding vertically in suitable bearings, I4, upon the front end of the standard, and provided wit-l1 a vertical diagonal slot, J4, to receive a stud or frictionroller, K4, at the upper end of lever B4. It will be seen that when the slotted plate H5 is vertically reciprocated it operates lever-B4, and through it the pivoted bracket X2 and the ratchet-wheel W3, the latter to any desired extent, which may be regulated by properly adjusting the fulcrum of the lever B4. The brush block or blank, which is in practice to be placed under the ratchet-wheel, is by the latter fed forward intermttingly between the drill and the needle. Y i

It is proper to state that upon the spindle B, under the end of lever P, is adjusted a spring or cushion, L4, to avoid any shock or unnecessary concussion during operation of the machine.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood.

By adjusting the tilting table C the brushlblock, which is placed thereupon, maybe bored at any desired angle.' When the machine is operated it is fed forward automatically by the mechanism described under the drill or auger, which,'as theleverP and spindle R move downward, bores a hole of the requisite size. The shuttle, which has in the meantime received a bunch of bristles, now moves forward through the wire loop carried up by the lneedle, which has at the saine time ascended. Next, the needle descends, causing the wire loop to draw the bristles through the opening in the brushblock. which is now fed forward, while the wire is tightened bythe clamping mechanism Q 13. Simultaneously the shuttle moves back for the reception of a new bunch of bristles, and the drill again descends for a repetition of the operation, the brush-block having been \nioved forward exactly the distance required.

My improved machine for making brushes is, as will be seen, nearly automatic in its operation, attendance being only required to replenish the box or hopper with 4bristles and to feed the brush-blocks. In spite of this it is very simple in its construction, effective in operation, and comparatively inexpensive.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statesf 1.
