Claims.
My invention relates to a process for forming brushes, and an object of my invention, among others, is to create a process by means of which brushes may be formed in a rapid and eflicient manner.
A means for carrying out t'he process, in the practice of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawing, in which- Figure 1 illustrates one of the preliminary steps in the process.
Figure 2 represents a subsequent step.
Figure 3 represents a further step and a portion of a mechanism by means of which this step may be eiiected.
Figure 4 illustrates another step in the process.
Figure 5 illustrates a brush complete after the last step of the process'has'been'eiiected.
Figure 6 is an isometric View of a portion of a machine'by means of which my improved process may be carried into effect.
Figure '7 is a similar view of a portion of the mechanism shown in Fig. 6 and illustrating a step in my improved process.
The steps embodying my improved process may be efiected in many different ways both mechanicall, manually, or partially by both combined, in fact a portion of the steps being most conveniently taken by manual operations. One
form of a machine in'whioh a part of the process may be efiiected is illustrated in theaccompanying drawings in which the numeral 8 denotes the base of a machine which may be used as hereinbefcre referred to and upon which a cam shaft 9 may be mounted in any suitable manner and 'to which cams for effecting different operations are secured, a cam iii engaging a clamp actutrting rod H for operating a clamp for holding a brush wire l2 while said wire is being operated upon to secure a brush material thereto in a manner that will presently appear. The clamp, however, not being necessary for a disclosure of the process a further showing thereof is omitted herein. The cam shaft 9 it will be understood is suitably connected to a motor for driving it a showing of such driving means being omitted herein.
A hopper l3 for a column M of bristles is supported upon the base 8 in any suitable manner the bottom of the column of bristles resting i upon the edge of a feed disk l5 rotatably mounted on the base with a portion of its edge traveling adjacent the edge of a guide It which is suitably curved to receive the edge of the disk I5 and guide movement of the bristles that are collected in bunches in notches H in the disk as shown in Fig. 6 of the drawing. The disk l5 is secured to "the end of a shaft I8 mounted in "a bearing l9 and driven as by means of a sprocket secured to the end of the shaft I8 and-mounting a sprocket chain 2! extending to "a sprocket 2.! secured to the shaft 9.
In practicing my improved method or process in the manner-illustrated by the machine shown herein the brush wire l2 upon which a hood has been loosely placed is inserted in the position shown in Fig. 6 with a'loop or handle 23 engaged with a retaining lug 24 and'the machine is set iii-operation as by pressing upon a pedal, thereby rotating the cam shaft and causing the cam Hi to actuate the clamping rod ll toclose the clamp 25 and secure the wire 52 in place. Immediately following this operation the sprocket d sk-s 2-2 and 20 connected by the chain 26 operate the disk 15 to collect in the notches l! a bunch of fibers from the column l4 and carry such. bunch intoa position over the shallow slightly bent U-sha'ped end 2%: of the wire l2. At this point'the movement of the bunch is stopped by interceptingprongs 21 of a holder, permitting the disk l5 to continue its rotation and thereby eject the bunch from the notch by action of an inclined edge of one side of the notch.
Sai'd holder comprises two plates 28 each having a notch 29 at itslower end created by 9. prong 2'1 anda holding prong-til as shown in Fig. 7 of 'thedrawing, thebunch 3i of bristles being held asshown in said figure. The plates 28 are secured to holder arms .32 extending from a hub -33 pivotally mounted on a pin 34 secured to and projecting from 'a. portion of the frame of the machine. A'finger 35 projecting "from the holder member comprising the parts just enumerated is engaged by a, holder operating cam 35 secured :to the cam shaft 9, said cam being formed to permit movement of the holder to engage the bunches of bristles at the proper times and to release said bunches.
With the brush wire I2 in the position shown in Figure 6 and with a bunch of bristles 3| in place thereon as just described, a looping cam 38 secured to the cam shaft 9 operates against a roller mounted in the forked end 39 of a loop forming bar til having its end shaped as a loop forming die l! which engages the U-shaped end of the wire 12 and bends it over the bunch of bristles, thereby creating a loop 42 enclosing said bunch of bristles.
Immediately following this operation a loop compressing arm 43 mounted on a pivot pin 44 secured to and projecting from a part of the frame of the machine is pressed downwardly into contact with th loop to close it and tightly secure the bunch in place. The hub of the arm 43 has a lever 45 extending therefrom with a roller on its end in contact with a compressing cam 46 secured to the cam shaft 9 and formed to timely operate the compressing arm to compress the loop at the end of the operation, and at which time the cam It! operates to release the clamp actuating rod H and thereby loosen the clamp to permit the wire I2 to be removed with the bunch of bristles secured in the loop and the hood 3'! loose upon the shank of the wire.
The hood is then closed down upon the bunch of bristles and by force applied to the hood the latter is forced over the bunch of bristles, bending and doubling said bunch into the form of a brush, as shown in Figures 4 and 5. During this operation of forcing the hood over the bunch of bristles the wire l2 will be suitably held, or reversing the operation, the hood may be held while force is applied to the wire to draw the bunch of bristles into the hood and thereby double the bunch within the hood so that a brush projecting from the hood will be formed.
In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that, within the scope of the appended claims, the invention may be carried out by other means and applied to uses other than those above set out.
I claim:
1. A process for making a brush that consists in placing a hood loosely over a substantially straight length comprising one end of a piece of wire with a looped handle formation at the opposite end, advancing and placing a straight flat layer comprising a wisp of brush material laterally across said substantially straight end, bending said substantially straight end around the wisp to secure the latter to the wire, and then forcing the hood over said wisp to double the latter edgewise within the hood to secure the hood in place with the brush material projecting from the mouth thereof.
2. A process for making a brush that consists in passing a hood member with an opening therethrough loosely over a substantially straight length comprising one end of a wire member having a handle formation larger than the opening through the hood at the opposite end thereof, advancing and placing a straight fiat layer comprising a wisp of brush material laterally across the end of the wire member opposite said handle formation, bending the end of the wire over said wisp to form a loop surrounding said wisp, and then holding one of said members and applying force to the other member to force the hood over the wisp and double the latter within the hood to secure the hood in place with the brush material projecting from the mouth of the hood.
3. A process for making a brush that consists in passing a hood member having an opening therethrough loosely over a substantially straight length comprising one end of a wire member having a handle formation larger than said opening at the opposite end thereof, advancing and placing a straight fiat layer comprising a wisp of brush material laterally across the end of the wire member opposite said handle formation, bending the end of the wire over said wisp and with its end tightly abutting the running part of the wire to form a loop surrounding the wisp, and then holding the wire member and applying force to the hood member to force the latter over the wisp to double it within the hood to secure the wisp in place with the brush material projecting from the mouth of the hood.
4. A process for making a brush that consists in inserting the substantially straight end portion of a wire member having a handle formation at its opposite end loosely through a hole in a hood member having a hole therethrough smaller than said handle formation, placing'the wire member with the hood thereon in a loop forming machine, placing a flat layer comprising a wisp of brush material by a lateral movement across the substantially straight end portion of the wire member opposite said handle formation, bending the end of the Wire by the action of said machine over said wisp and tightly abutting the running part of the wire, thereby forming a complete loop to enclose and secure the wisp in place, and then effecting a relative movement between said members to draw the wisp into the hood, thereby doubling it to secure the wisp in place with the ends thereof projecting from the mouth of the hood.
5. A process for making a brush that consists in placing a wire having a substantially straight portion at one end with a handle formation at its opposite end and a hood loosely supported thereon between the jaws of a clamping device, securing said wire between said jaws, placing a wisp of brush material by a lateral movement across said substantially straight portion, forming a complete loop around said wisp to secure the latter to the wire, manually removing said Wire from between said jaws, and then effecting a relative movement between said members to draw the wisp into the hood, thereby doubling it to secure the wisp in place withthe ends thereof projecting from the mouth of the hood.
