SPECIFICATION forming part of Letters Patent No. 351.909, dated November 2, 1886.

Application filed July 17, 1884. Serial No.13'1,960. X model.)

To all whom it may concern:

Be itknown that I, ALANSON O. ESTABROOK, of Florence, town of Northampton, in the county of Hampshire and State of Massachu= setts, have invented certain new and useful Improvements in Machines for Bunchin g Bristles; and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a.clear, true, and complete description of the several featuresof my invention.

In another application for Letters Patent, No. 187 ,959, I have described and claimed several improvements in machines of this general class, and some of said improvements, when broadly considered, are embodied in the machines'hereinafterdescribed, All of my said improvements are limited to machines which embody, in combination, a bristle-hopper and a notched blade, by which a tuft of bristles is separated from the mass and presented or delivered for grasping by a brush-maker, prep'aratory to further manipulation necessary in the'manufacture of brushes; and the particular improvements which constitute the subject of this application are limited to such machines as contain, essentially, a notched circular blade, whether it be organized to operate reciprocally or to be moved always in one direction, whether continuously or intermittingly. Althoughmachines embodying my improvements are adapted to general service, I'have organized them with special reference totheir use in connection with the manufacture of 3 5 light fine brushes, and also with special reference to simplicity and economy in construction.

After a detailed description of machines embodying my improvements, the features of in- 0 vention intended to be hereby secured to me will be specified in theseveral claims hereunto annexed;- Referring to the drawings, Figures 1 and 2 are respectively front and rear views of a reciprocating ci'rculavnotched-blade machine embodying my'improyements. Figs. 3 and 4 are opposite or end views of the machine. Fig. '5 is a front view of a similar machine 1 having a circular notched blade organized to 5o'be moved always in one direction.

a rear view of the same.

1 shown.

Fig. 6 is The table A ofthe machine may be constructed in any desired manner. The frame B may also be variably constructed without departure from certain portions of my inVention, but having economy of construction in view I have devised the particular frame It is mainly composed of a single casting, including a triangular base, a, and an annularblade-head, b, int-egral'therewith. Below the blade-head, at both sides of the machine, the frame is slotted for the reception of rolle'rs,to bchereinafterdescribed. At the rear side of the frame a back plate, 0, is adj ustably secured by screws 0 in slots 0. plate serves a double purpose, it being an ad justable standard-bearing for the axis d of the notched circular blade 0, which may revolve, but'is preferably reciprocated within the bladehcad b, and it also serves as the back plate of the bristlehopper D. In Figs. 1 and 2 the circular or disk blade C has a single tuft-gathering notch, e, and is therefore organized to be reciprocated or rocked to and fro by means of a treadle (not shown) coupled thereto by the long link or rod f, lever f, and the link 7.

This machine, when intended to serve for but one brush-maker, has but one tuft-delivering point, g,which is on the front side of themachine, the annular head being cut away, as shown, to afford space for a thumb and finger in grasping the tuft; but when arranged to serve two brush-makers it is provided with a second delivery-point, g, at the rear side of the machine. As the vibratory movement of 'the blade need be no more than, say, ninety degrees, the disk can be provided with at least three notches of different sizes equidistant from each other, so that either notch may be employed,according to the size of tuft desired.

The bristle-hopper D is as described in my aforesaid application for Letters Patent, and is a loop shaped and contractible flexible hopper having a mouth, h, at the lower side 'of the annular blade-head, andis composed, 95 mainly, of a band or belt; t',..which at one end 7 is secured to the frame B, thence passes upwardly over a roller, i, mountedin said frame, thence descends, forming a loop within the triangular base, thence passes upwardly over a second roller, 72, and then away from the frame, and it is maintained undersuitable This back 6 tension by a cord and spring, or by a weight, 1'", as shown. Both ends of the band or belt may, if desired, be provided with a weight or spring. The circular blade 0, being always across and closing the hoppermouth 71, serves in one sense as the upper wall of the hopper. The back plate, 0, before described, also serves as its rear wall. The bristles k are placed in the loop, and when the weight is free to act upon the belt or band t the bristles are forced upwardly against the blade, and when the notch of the latter is moved across the mouth it is readily filled with bristles, tufts of which are carried first to one side of the hopperunouth for one bruslrmak er, and then to the other side for a second brushmaker; or, if but one person is to be served, the

reciprocating movement is lessened, so as to cause the notch to sweep from one side of the month to either point of delivery. Those portions of the annular blade-head b which extend from each side of the hopper-month h to the tuft-delivery points 9 g constitute notchclosing or tuft-bearing surfaces, by means of which the notched disk is enabled to control and carry the tufts, after gathering them, during the passage of the notch across the mouth of the hopper. Should the disleblade and the blade-head become worn at their points of contact, it can be compensated by the adjustability of the back plate, 0, and this also enables the blade to be set accurately for properly operating on filaments of various kinds.

Machines have heretofore embodied a hopper and a circular notched blade; but mine differs from said prior blades in that it has a truly radial notch instead of a tangential notch, as heretofore. The novel radial notch enables the blade to separate and deliver a tuft on each side of the hopper-t'. e., at each of its movements, as now for the first time provided for by lne while the tangential notch is only capable of operating in one direction, and the edges of the radial. notch are obviously less liable to cut bristles than those of the tangential notch.

I-Ieretofore the disk-bladc has not been ad justably mounted in its bearings, and it has always been located below the hopper. By having the hopper below the blade, as in my machine, the bristles are lifted with uniformity into a notch, are better controlled, and are more readily observable and accessible for adjustment from time to time.

Heretofore, with a circular blade, a box hopper and a weighted lever have been employed for holding the bristles and forcing them downward upon the blade, and as the hopper was wider at the bottom than at the top the entire weight of the mass of bristles, as well as of the weighted lever, was borne by the notched disk, whereas in my machine the bristles are lifted with only sufficient pressure to enable them to promptly enter the notch, and the flexible loop-shaped hopper exerts an encircling and a lifting pressure on the mass of bristles, causing them to be well pressed upwardly at the center of the mouth, and to always properly fill the mouth of the hopper, but to be pressed with but little abrasive contact against the circular blade at either side of the mouth.

\Vith this machine I employ an agitator or means for intermittingly varying the pressure on the bristles, which constitutes a portion of the invent-ion described in my other application for Letters Patent hereinbeforc referred to.

While the hopper for obtaining the best results should be located below the disk-blade, it can be otherwise located with reference to the periphery of the disk without departure from certain portions of my invention.

Referring now to the machine illustrated in Fig. 5 and 6, it will be seen to differ from the machine already described in having numerous tuft-notches c, and the blade is arranged to be intermitiingly rotated continuously in one direction by means of the ratchet-wheel Z, secured to the axis of the disk-blade, the lever-arni l, freely pivoted on said axis and coupled to atreadle by the rod Z and the springpawl Z on said arm for engaging with the teeth of the ratchet in a manner well known. This machine is also arranged to serve one or two persons, and its tuft-notches may be tan' gential instead of radial, and yet operate with but little liability of cutting the bristles, be cause the latter are not, as heretofore in diskblade machines, largely supported by the blade, and because they are subjected to pressure in the peculiar manner described. The only objection to moving the disk-blade always in one direction is, that the bristles in the mouth of the hopper are not being eonstantly adjusted by a to-and-fro movement, which serves to insure parallelism, and there fore I prefer the reciprocating disk.

It will be seen that so far as relates to the operation of the machine, Fig. l, the upper portion of the annular blade-head performs only a guiding or steadying function with relation to the circular blade, and hence the disk and the head may be both segmental in form without materially affecting the results; but in the machine, Fig. 5, the entire head eooperates with the notched circular blade for closing the notches and holding tufts of bristles, which can therefore be taken from various points around the blade.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a bristle-bunching machine, the com bination of a bristle-holding hopper and a circular blade having one or more radial tuftnotches and crossing and closing the mouth of the hopper, substantially as described.

2. In a bristle-bunching machine, the combination of a bristle-holding hopper and a circular blade crossing and closing the mouth of the hopper, and having one or more tuftnotches and organized within a head, sub- IIO stantially as described, for the delivering of tufts of bristles at different points in the machine, as set forth. 7 r

3. In a bristle-bunching machine, the combination of a notched circular blade and a flexible and contractible bristle-holdinghopper having a contracted mouth crossed and closed by said blade, substantially as described.

4:. In a bristle-bunching' machine, the-combination of a bristle-holding hopper, an annular blade-head, and a notched circular blade which is adjustable within the bladehead, substantially as described.

5. In a bristle-bundling machine, the comframe B, having the open base for the recep- 20 tion of the bristle-hopper, and the annular head forthe reception of said blade, substantially as described.
