BLOCK-HOLDER FOR BRUSH-MACHINES.
SPECIFICATION forming part of Letters Patent No. 623,560, dated April 25, 1899.
Application filed April '7, 1393- Serial No. 676,777. (No model.) i
T (LZZ whom it may concern:
Be it known that I, WALTER O. READ, of Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Block-Holders for Brush-Machines; and I do hereby declare the following to be a full, clear, and exact description of the said invention, such as will enable others skilled in the art to which it :0 relates to make, use, and practice the same.
The object of my invention is to provide the table of a brush-machine with suitable guide-plates for supporting and guiding the block-holder and which are so curved that I 5 the block-holder may be held thereon at any desired angle of inclination when boring the perforations in the block, so as to give the desired spread to the tufts of the brush when the latter are placed in the perforations of the block; to provide the block-holder with registering devices and the table with a pin to engage therewith, so as to facilitate the accurate boring of the block and the placing of the tufts in the perforations, to provide the block-holder with a suitable backing, so as to prevent the splintering and burring of the block as the perforations for the tufts are bored therein, and to make the devices for holding the blocks in the block-holder adjustable, so as to take blocks of varying lengths, widths, and thickness, andbyusing backings of different thickness between the block and block-holder to vary the distances between the perforations from center to center as may be desired.
This invention is particularly designed to give to a completed brush the spread of the usual hand-made brush, in which the tufts are put into the back at an inclination, so as to spread the ends of the tufts.
In the drawings which form a part of this specification and in which similar letters of reference refer to similar parts wherever they occur, Figure 1 is a side elevation of a boringmachine having my improved block-holder applied thereto. Fig. 2 is a side elevation of my block-holder, part of the latter being broken away, so as to show the pin on the table engaging with one of the depressions in the templet of the block-holder. Fig. 3 is a plan view of table and block-holder. Fig. 4 is a view showing the bottom of the blockin any other desired manner.
holder. Fig. 5 is a transverse section of the block-holder, showing same supported on a portion of the guide-plates and in one of its most inclined positions. Fig. 6 is aplan view of one of the back'ings that I use in my blockholder. Fig. 7 is a transverse section showing a modified form of block-holder, in which the bottom of the templet is concaved in shape. Fig. 8 is a side elevation of a portion of the block-holder, showing the adjustable points for holding the blocks.
It should be understood that the boringmachine or brush-machine, the latter being employed for inserting tufts in the brushblock, form no .part of my present invention, which relates exclusively to the block-holder and means for supporting and operating the same, which may be used with any desired machine to which it is applicable.
Referring tothe drawings, A is an angleiron orbaseplate which when in use is fastened by screws or bolts to the table of a boring or tufting machine, as shown in Fig. 1. To the upwardly-extending wing or part A of this angle-iron or base-plate I secure two thin metal guide-plates B "3 by screws or bolts or In the center of the angle-iron or base-plate A and projecting upwardly therefrom is a pin C, the upper end of which is suitably formed to engage with depressions formed in the bottom or templet of the block-holder. The block-holder consists of the base-plate D, upon which is secured a bottom or templet D,provided with rows of depressions D which, in conjunction with the pin 0, which engages therein, serves to guide the operations of boring and to fting. The base-plate D is provided at each end with downwardly-extending lugs (Z, to which are secured plates (1, the lower extremities of which are prolonged, forming two rests (Z (Z at each end of the block-holder.
Upon one side of the base-plate D is a 5 channeled block E, in which is adj ustably secured by a set-screw e a slotted plate E, the upper end of which is provided with a setscrew E The opposite side of the base-plate D has two upwardly-extending slotted lugs E E in which the screw-threaded points E E are adjustably secured by means of the set-nuts 6 6 The brush-block X is held between the set-screw E and the points E E when it is to be bored or when the brush-tufts are to be inserted, and as the set-screw E and the points E are adjustable in both directions both up and down and horizontally it will be evident that they will accommodate not only blocks of different widths, but also blocks of different heights as well. The base-plate D is also provided upon its upper surface at one of its outer extremities with two upwardly-extending lugs (Z 61 forming a way or channel, in which is adjustably secured a slotted stop (Z The stop (1 may be secured in any desired position between the lugs (1 (Z by means of the set-screw (Z thus forming an adjustable stop for the blocks X as they are inserted in the block-holder for boring or inserting the tufts.
As shown in Figs. 1 and 2, the upper surface of the guide-plates B B is curved longitudiually, the curve in the'surfaces of the plates being the same at equidistant points from the center or pin 0. The block-holder is placed on the guide-plates B B, the plates (1 resting upon the upper curved surface of the same, while the rests d d" straddle the said guide-plates, one upon each side, and rest against same when the block-holder is inclined to the one side or the other. The block X to be bored or receive the tufts is then placed in the block-holder and secured therein between the stop (1, the points E E and the set-screw E The block-holder is thus brought directly under the boring-bit or tufting device of the machine ready for work. \Vhile the longitudinally-curved guide-plates B B thus serve to produce a finished brush in which the end tufts will be spread longitudiuaIly they will not, however, of themselves spread the tufts along the sides of the block. To produce this latter effect, I incline the brush-holder from side to side upon the guide-plates B B, the ends of the rests (Z (7 being the center or pivot, as is clearly shown in Fig. 5. along the sides are made and are presented to receive the tufts at an incline to the surface of the block X of the brush, and the tufts are caused thereby to produce a spread appearance when they are attached to the block X.
The bottom or templet D is, as before stated, providedwith rows of depressions D corresponding to the rows of perforations to be bored in the block X and the tufts to be placed in the brush. The pin G engages with the depressions D and registers with the boring-bit or tufting device, so that as the blockholder is moved along upon and from end to end of the guide-plates B B the pin C will engage with each of the depressions in a row, one after another in its order, and as it engages therewith the boring-bit may be brought down to bore a perforation or the tufting device to insert a tuft. \Vhen one row is finished, the block-holder may be moved to either the one side or the other until the pin C engages with the proper depression in the next row, this operation being repeated until In these positions the perforations,
all the perforations are bored or all the tufts are inserted.
The outer ends of the guide-plates B B are given an extreme curve downwardly. These curves permit the ends of the block-holder to be depressed,while the end of the block-holder resting over the pin C is inclined. As a result the perforations formed in the block will be correspondingly inclined, and in the same way thetufts inserted will also be inclined and have the desired spread. As the position of the block-holder is changed longitudinally, the angle'of the inclination is gradually increased or diminished as the block-holder is moved the one way or the other to or-from the pin 0, according to the curve of the guideplates B 13, upon which the block-holder is supported. In being thus shifted it is evident that the tufts of the brush are given a gradual spread or inclination from the upper surface of the block to the outer ends. This produces in the finished brush a gradual rounded or spread end, permitting the brush to have an enlarged operating-surface for the ends of the tufts. In order that the ends of the rests (Z (1 may have a bearin g against the guide-plates B B, the rests are inclined inwardly toward each other, being separated just a sufficient distance apart at their lower extremity so as to admit of the free passage of the guide-plates B B between them.
Brushes are manufactured in two principal ways. Either the perforations for the tufts are bored entirely through the block X or they are bored only partly through the block X and the tufts are then inserted in these perforations. Brushes may be madein either of these two ways with my block holder. hen I bore the perforations entirelythrough the blocks, it is necessary, or at least preferable, to use a backing F, (see Fig. (5,) usually of wood. This backing F is placed immediately over the bottom or templet D of the block-holder, and the block X to be operated upon is then placed over the backing F and secured in place between the stop dl,tl1e points E E, and the set-screw E ashereinbefore described, and the perforations may then be bored, the bit being so adjusted that it will pass entirely through the block X and into the backing F, but not through the same. The backing F will when thus used serve two useful purposes. In the first place it will prevent the bit from striking the metal templet D and becoming broken or dulled, and, furthermore, a bur F will be formed by the bit in the backing F, which will prevent the splintering of the wood of the block X around the perforations bored, making clean and perfeet perforations.
In order that the block-holder may at all times rest firmly upon the guide-plates B B and have a solid bearing thereon without any lost motion no matter in what depression in the bloek-holder the pin 0 may be, it will be evident that the arches d in the plates d, formed between the rests d (1 must be properly constructed and that care must be eX- ercised in forming the depressions D in the templet D. For instance, referring to Fig. 7, it will be evident that the arches (Z must be so formed that when the pin O engages successively in the depressions lettered d, d, and (Z the plates d shall rest solidly upon the guide-plates B B at the points lettered b, h, and 11 respectively. In other words, the arches (i must be so constructed that when the pin 0 is seated in any depression in the templet D the plates d shall rest upon the guide-plates and have a solid bearing thereon no matter at what angle of inclination the block-holder may be or-in what position upon the guide plates the blockholder is.
Vhen the blocks to be operated upon have a flat surface, the templet D may be fiat. If the blocks have a rounded surface, the templet used may have its under side curved in substantial agreement with the surface of the blocks. It will also be noticed that by using backings F of greater thickness than usual and by adjusting the stop (1, thepoints E E and the set-screw E to suit I may not only use thicker blocks X, but by raising the blocks X away frontthe templet D, I can vary the distances between perforations from center to center as desired. My improved blockholder is thus entirely adjustable, so that I can use blocks of varying sizes and thickness as well as lengths; but I can also vary the depths of perforations and the distances apart and the angle of inclination as desired. I may also change the contour of my guideplates as desired, and by altering the curvature of the upper surface of the guide-plates the arches d of the plates d and the lengths of the legs of the block-holder not only secure any spread of tufts desired, but also operate upon blocks of any size and even of great irregularity.
.Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a brush-machine, the combination with the table, of the curved guide-plates and pin carried thereby and the block-holder having a plurality of seats to engage said pin and having a sliding connection with the guideplates, substantially as described.

8. In a brush-machine, the combination with the table, of the vertically arranged guide plates and pin carried thereby, the block-h0lder, the templet having its surface curved to correspond to the curve of the brush-block to be operated upon and having a plurality of seats or recesses adapted to be engaged by said pin and rests carried by said block-holder adapted to slidingly engage said guide-plates, substantially as described.
9. In a brush-machine, the combination With the table of the vertically disposed guide-plates and pin carried thereby, the templet having a plurality of seats or recesses adapted to be successively engaged by said pin, and the rests carried by the block-holder and adapted to slidingly engage the guideplates, said rests comprising the depending arms having arches connecting them at the upper portion adapted to rest upon the edges of the plates and permit rocking movement of the block-holder transversely of the guideplates, said arms converging toward their lower ends to closely embrace the guideplates, substantially as described.
In Witness whereof I have hereunto set my hand in presence of two witnesses.
