TUFT-FASTENER GUIDE FOR BRUSH-MACHINES.

SPECIFICATION forming part of Letters Patent No. 746,943, dated December 15, 1903.

dpplication filed April 16, 1903.

To all whom it may concern.-

Be it known that we,OHARLES E. FISHER and McCLIN'rocK YOUNG, of Frederick, county of Frederick, and State of Maryland, have invented a new and useful Improvement in Taft-Fastener Guides for Brush-Machines, of which the following is a specification.

This invention has reference to the man ufacture of brushes, and particularly to machines which operate to seat and fasten a tuft of fibers in a hole in the brush-block by means of a tuft-fastener, usually in the form of a staple. In machines of this character, of which the patent to McGlintock Young, No. 578,907, of March 16, 1897, is an example and to which reference may be had for a more detailed description than is here given, the tuft to be fastened in the block is straddled by a staple and the latter driven into the hole in the block, this action doubling the tuft on itself and carrying the same into the hole and firmly fastening it therein. The particular mechanism of this patent for effecting these operations comprises a sliding member or guideprovided with a longitudinal slot or groove, in the end of which the staple is held, and at proper times this slide is moved downward to the brush-block, seating the staple in its passage astride the tuft and doubling and carrying the same down:

ward to the block, at which point the slide.

comes to a rest, with its end slightly entering the hole in the block or in close proximity to the same, so as to form a guideway for the staple, whereupon the staple is acted on by a driving-plunger mounted in the groove in the guide, which driving-plunger forces the staple, with its double tuft, into the hole and fastens the same in position. This slid-, ing guide of the patent is constructed of two plates mounted fixedly with relation to each other on a movable head and set aslig-htdi-s tance apart, so as to form the longitudinal slot for the plunger and staple, and the block being presented at right angles to the axis of the guideway an uninterrupted guideway is formed for the passage of the staple and tuft into the hole in the block,jthe tufts seated in this way standing at right angles to the face of the block. Many brushes, however, are

-' the same on the line a'a.

Serial No. 162,823. (No model.)

made with flaring tufts-that is, the tufts are seated and fastened so that they will extend at an inclination or -flare with reference to the face of the block, audio seating tufts in this manner it is the practice to present and hold the block in an inclined position i .the latter will not enter properly into the block and will not fasten the tufts with the required efiectiveuess and accuracy.

It is the aim of this invention to overcome this objectionable feature; and theinvention consists in so constructing the guide for the staple that it will adjust or accommodate itself to the face of the block notwithstanding the angle at which the block is disposed with relation to the guide.

The invention consists also in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a front elevation of our improved device. Fig. 2 is a vertical longitudinal section through Fig. 3 is a transverse section on the line b h. Fig. 4 is a transverse section on the line d d. Fig. 4? is an elevation of a modification. Figs. 5 and 6 are diagrammatic views showing the progressive action of the device in presenting the staple and'tuft to the hole in the block. Fig. 7 is a diagrammatic view showing the action of my improved device when the block is presented in one inclined position. Fig. 8 is a similar view showing the action of the device when the block is presented at the opposite inclina- Fig. 9 is a sectional elevation of suchportionsof a brush-machine as are necessary to illustrate our invention, the same showing our improved tuft-fastener guide embodied therein.

Referring to the drawings, A represents our improved tufting-slide,comprising two plates at a, mounted side by side on a head B, which is adapted to be reciprocated vertically, so as to carry the tufter to and from the brushblock. These plates are set a slight distance apart to form between them a longitudinal slot or guideway C, and at their lower ends the plates approach a point, so that they may be presented with accuracy to the hole in the block to be filled. For a slight distance back from their ends the adjacent faces of the plates are grooved longitudinally, as at-a Figs. 1, 5, and 6, to receive the legs of the fastening-staple and to form guideways for the same when it is driven into the block, which is effected by a plunger D,mounted in thelongitudinal slot between the platesand adapted to be operated at the proper time to drive the staple into the hole in the brush-block. A's heretofore constructed, the two plates forming the g-uideway have been fixed with relation to each other, and, as shown in Figs. 5 and 6, the action of the guide in its down ward movement is to bend a section of wire over an anvil e to form the staple E, which staple is received between the grooved faces of the plates (1 a and by which it is carried over a wisp of fiber F, thereby doubling it and carrying the same down ward to the block G, Fig. 6, at which point it comes to a rest, and the staple is driven into the block by the plunger. In the position of the parts shown in Fig. 6 withthe block at right angles to the axis of the guideway between the plates both plates are in contact with the face of the block, and a continuous and uninterrupted guideway is formed for the passage of the staple when acted on by the plunger. If, however, the block is presented at an inclination to the guide to seat a flaring tuft, one of the plates will contact with the block and form a guide for the staple; but the other, owing to the fact that the plates are fixed with relation to each other, will terminate some distance from the block, so that at this side the staple will not receive a lateral guiding support. In our improved construction, as represented in Figs. 1, 2, 3, 4, 7, 8, and 9, we mount these plates so that one will yield endwise with respect to the other, the result being that, as shown in Fig. 7, when the brush block is presented at an angle both plates will contact with the same and form guideways for the staple at both sides. In these figures we have represented a form of construction wherein both plates are adapted to yield independently of each other that is, each with relation to the otherso that there will be presented for the staple continuous and uninterrupted guideways at both sides when the block is presented at opposite inclinations; butit will be understood that the invention comprehends a construction where but one of the plates is movable with relation to the other, as shown in Fig. 4:", the essence of the invention residing in means, broadly, of maintaining a continuous and uninterrupted guideway for the staple at both sides'notwithstanding the position at which the block is held. Referring to said figures, it will be seen that the plates aa are seated so as to slide on longitudinal ribs b 1) 6 extending outward from the face of the head B, the space between the ribs constituting two longitudinal grooves 19 b Seated on these plates and confining them is a cap-plate H, provided on its under side with two longitudinal ribs 71 h, which extend through longitudinal slots a a formed in the plates a a, and into the longitudinal grooves in the head B. This cap-plate is held firmly in place by fasteningscrews 77?, extending through the ribs and into the head B. The slots a a in plates a a are slightly longer than the ribs h 77., so that the plates may move endwise with relation to the head and cap plate, their movements being limited by the contact of the ends of the ribs with the ends of the slots. The upper ends of plates at a are acted on by spiral springs I l, seated in longitudinal sockets in the head and bearing at their opposite ends on the ends of the plates at a. These springs tend to project the plates to the limit of their downward movements with respect to the head, but permitthe plates to move independently endwise. The springs thus applied normally hold the plates yieldingly, so that their ends will be on the same level, as shown in Fig. 1, and when the block is presented to the device at right angles both of the plates will contact with the face of the block and form guideways for the staple at both sides. When the block, however, is presented at one inclination, as shown in Fig. 7, the plate a will yield endwise, thereby compressing its spring, and will accommodate itself to the inclined face of the block, so that continuous guides are formed for the legs of the staple. When the block is presented at the opposite inclination, as shown in. Fig. 8, the opposite plate a will yield, thereby compressing its spring. In order that the parallelism of the plates where they project below the head may be maintained and in order that at this point they may be truly guided and prevented from springing apart or separating, we fix to the rear side of the plate a a transversely-extending finger K, which is extended at the back of the opposite plate a and is provided with a forwardly-extending lug 7c, projecting through a longitudinal groove is in the plate a. This construction admits of a free longitudinal relative movement of the plates, but prevents movement in any other direction that is, laterally.

In the foregoing description it will be seen that while the plates are yieldable independently with respect to each other they are also yieldablesimultaneouslyandtogether. This is advantageous in that in the event of irregularities in the thickness of the blocks the device as a whole will adjust itself to these con-.

ditions, and the cushioning action of the springs will prevent breakage or injury of the parts. Furthermore, by reason of the yielding plates they will adjust themselves to local irregularities in the surface of the block, and under all conditions of this character the staple will have a continuous guideway in which it will be given support in its passage into the hole in the block.

Having thus described our invention, what we claim is 1. A tuft-fastener guide having one of its walls movable longitudinally with respect to the other Wall.

2. Incombination withsustainingmember, a tuft-fastener guide comprising oppositelydisposed walls between which the tuft-fastener is guided, said walls being movable longitudinally independently of each other and with relation to said sustaining member.

3. In combination with a sustaining member, a tuftfastener guide comprising two walls mounted on said member and yieldable longitudinally with respect to the same.

head with a space between them constituting a longitudinal tu ft-fastener guide, one of said plates being movable longitudinally with respect to the head, and a spring acting on said movable plate and tending to hold it yieldingly against longitudinal movement.

5. In combination with a sustaining member, two plates mounted thereon with a space between them constituting a tuft-fastener guide, and movable longitudinally independently of each other, and springs acting on said plates and tending to hold them yieldingly against longitudinal movement.

' In testimony whereof We hereunto set our hands this 14th day of April, 1903, in the presence of two attesting witnesses.
