APPARATUS FOR THE MANUFACTURE OF BRUSHES.r

SPECIFICATION forming part of Letters Patent No. 421,531, dated February v1,8, 1890.

Application tiled March 2, 1889. Serial No. 301,771. (No model.)

` zen of the United States, residing at Detroit,

county of lVaynaState of Michigan, have invented a certain new and useful Improvement in Apparatus for the Manufacture of Brushes; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this speciiication.

My present invention relates to new and useful improvements in apparatus for the construction of brushes, and has reference more particularly to the manufacture of brushes such as are embodied in a'pending application filed by me August 24, 1888, Serial No. 283,607.

To this end my invention consists of the devices and appliances, together with their combinations and arrangements, as more fully hereinafter set forth, and pointed out in the claims, and `as more particularly illustrated in the drawings submitted herewith, in which- Figure 1 is a vertical section across the machine and brush, illustrative of my invention. Fig. 2 is a vertical longitudinal section through the same. Fig. 3 is a plan view of the clamp. Fig. 4 is a side elevation thereof, and Fig. 5 is a view in perspective of one end of said clamp. Fig. 6 is a view of a brushhead.

The brush described in the above -named application consists, essentially, of a head A, made in a single integral piece provided with one or more longitudinal grooves or sockets a, terminating toward the extremities of the head with sockets a a2 deeper than the lon gitudinal socket a, and preferably extending at an angle or inclination thereto, as shown in Fig. 2. Into this groove a and end sockets a c2 the stock B is forced, the stock being looped over and held by a binding-wire C, eX- tending the length of the groove, the ends of the wire, with the stock, being forced also into the end sockets a a2, nails a3 being driven into the head to hold the stock and bindingwire in place. The said end sockets communicating with the longitudinal groove, it is evident that a` single binding-wire will hold the stock therein. Y

I will now proceed to describe my present invention, which I carry out as follows: To force the stock and binding-Wire into the respective grooves,I employ a driving-plate D. The stock is looped or bent over the bindingwire O by forcing said plate with the stock and longitudinallyextended bindingwire into a clamp E. This clamp consists, essentially, of the sides E E2 and end blocks E3 E4, properly united, and with or without the extended base-plates ee,which are perforated, as shown at c2, to form an engagement of the clamp upon a suitable support, as upon pins F, Figs. 2 and 4. The end blocks are constructed with guide-recesses e3 to receive the driving-plate. In order that the stock and binding-wire may be properly driven into the end sockets a a2, which are deeper than the longitudinal groove communicating therewith, it is evident that the driving-plate D must be constructed with projected shoulders or points d d', extended below the level of the intermediate edge d2 of said plate, so that while the stock in the longitudinal groove is forced into place by the driving edge d2 at the same time the stock is also driven into the end sockets by the extended points d d', and as the binding-wire is to be bent over into the said end sockets the said points are constructed with an angularA lower edge, as shown. The plate is provided with any desired number of recesses d5, through which the nails may be driven into the head, still allowing the free removal of the plate when the stock and binding-wire are nailed into place.

Another feature of my invention contemplates the bunching of the stock at the ends of the brush to make the brush thicker and heavier at its extremities. To accomplish this result, I cut away the sides of the clamp adjacent to the end blocks, as shown at c". The inner edges'of the end block at either side of the guide-recesses c3 are also cut back, as shown at c5, to allow the insertion and bending over of an additional amount of stock at the ends of the brush.

IOO

In practice the stock may be bent or forced into the clamp before the application of the Same into the head in a separate operation, the clamp, with its contents forced therei nto, being brought into proper position to be driven into the groove of the brushhead in connection with the operation of nailing.

I do not limit myself to any particular means of forcing the driving-plate into the clamp and brush-head; but it may be acco1nplished by a driving-arn1 G, the saine, however, forming no part of this application.

It will be understood that in the use of the apparatus herein described the fiber or stock is laid erosswise on the upper edges of the clamp, the binding-wire laid thereupon intermediate the ends of the fiber. The drivingplate is then forced into the clamp, driving l the stock and looping it over the bindingq wire. Then the clamp with its stock and plate thus engaged therewith are located upon the grooved brush -head, a further pressure of the plate drives the stock and bindingwire into the longitudinal and connnunicating end grooves and bends the ends of the 3 said Wire into said end grooves. If the baseplates e e are not used, the end blocks may be recessed, as shown at e, to engage the clainp in place. In this event the pins F are of course secured nearer together and may be made longer, so as to engage the recesses e".

That I claim as iny invention herein isl. The driving-plate D, provided with extended driving-peints CZ d and intermediate driving-edge (Z2, constructed with recesses d, said driving-points projected beyond said diivingedge, substantially as set forth.

2. The combination, with a driving-plate provided with extended driving -points and an intermediate driving edge constructed with recesses, of a clamp consisting of parallel sides having at their ends blocks, in which the side edges of the driving-plate slide, substantially as set forth.

In testimony whereof I sign this specifica tion in the presence of two Witnesses.
