23 Claims. 1

The general object of the invention is to provide a semi-automatic machine for making brushes from brush strips each of which comprises a channel member carrying transversely projecting brush fibers.

A more specific object of the invention is to provide an improved machine for the purpose stated which serves to engage a brush strip and to wind it upon an arbor to a predetermined limited extent to form a brush, the brush then being supported on the arbor and being removable therefrom by endwise movement.

Another more specific object of the invention is to provide a machine for the purpose stated which serves not only to engage and wind a brush strip as described but also serves to automatically cut the channel member of the strip upon the completion of winding so as to sever the wound brush from the unwound portion of the strip.

Further specific objects of the invention are to provide various features of structure and arrangement whereby the before-stated objects are advantageously attained.

Other objects of the invention will be apparent from the drawings and from the following description and claims.

In the drawings I have shown in detail a preferred embodiment of the invention, but it will be understood that various changes may be made from the construction shown, and that the drawings are not to be construed as defining or limiting the scope of the invention, the claims forming a part of this specification being relied upon for that purpose.

R.eferring to the drawings, more particularly Figs. 1 to 3 thereof, It] represents as an entirety a brush strip which is adapted to be used in a machine embodying the invention for the making of a brush. The strip comprises a longitudinal metallic channel member l2 which is preferably symmetrical with its side walls converging. Fibers l4 arranged in a layer are looped or folded within the channel, but fibers extending around a longitudinal retaining wire I6. The term fibers is herein used in a generic sense and is intended to include vegetable fibers or animal bristles or synthetic fibers or any other filaments adapted for the intended purpose. During manufacture of the brush strip the side walls of the channel member are initially parallel or approximately parallel and the wire [6 and the fibers i4 are pressed into the channel member, the fibers being folded by reason of their engagement with the channel member side walls. Thereafter the side walls of the channel member are bent toward each other to the inclined positions shown, the side walls thus gripping the fibers so that the fibers and the retaining wire are held in place.

By means of the machine embodying the invention a length of the strip 10 is bent or wound so to form a brush l8 having a shape such as that shown in Fig. 3, and the wound i8 is cut ofi from the remainder of the strip It. The invention is not limited to the formation of a brush having the particular triangular shape shown and by changing the shapes and proportions of certain parts of the machine brushes, O other shapes can be made.

Referring to Figs. 4 to 19 of the drawings, 25 is a main bed or base which carries the other parts of the machine. Rptatably mounted in suitable bearings on the base 20; is a longitudinal horizontal shaft 22-. Mounted above the shaft 22 on suitable. supports. carried by the base 25. is an electric motor 24 connected with a speed reducing mechanism 26 having a projecting longitudinal drive shaft 28;. A sprocketwheel an is con.- nected with the shaft 28, this sprocket wheel being preferably connected: by means of an overload slip clutch 3.2 which will yield when necessary to. prevent dama e t-.part s, of the machine.

Means is provided; for rotating the shaft 22 to a predetermined limited; extent, and as shown the said meansrotatesthe shaft through a single revolution. For this purpose a single revolution clutch 3.4. is mounted on the shaft 22-, the clutch having its driving element connected with the said shaft and, having its driven, element connected with a, sprocket wheel 36; in register. with.

the sprocket wheel 30, An andless chain 33- extends. around. the two. said. Sprocket wheels, and

At its left end the pin 59-carriesv a conical member; 52 having an. annular groove 54 therein. Movement of the pin- 5.0.toward the right is. limited by a stop 53, which This v engages the member 52. A manually operable lever 56 is provided which is movable about a vertical axis at 58, and this lever carries a shoe which is entered in the annular groove 54 of the member 52. A spring 60 biases the lever 56 to the position shown by full lines in Fig. 4. When the lever 55 is in the last said position the pin 50 projects from the plate 48. to the extent permitted by the stop 53 and the conical member 52 is in its position toward the right and out or engagement with the lever 40. The lever 49 is in the position shown in Fig. 11, the shaft 22 and the'driving member being held against rotation. llvhen the. lever 56 is moved to the position shown by dotted lines in Fig. 4. the pin is retracted and the conical member 52 is moved toward theleft to, engage the lever 48 and move it to the position shown in Fig. 13. This initiates rotation of the shaft 22 and of the driving member 45. As soon as rotation has started the lever as. is released and. the pa t ar re to ed: to their former positionsbythe; spring 59;. Rotation con.- tinues for. one. omplet r v l n. bei g then stopped. by he. entry; o 6 1111 M into the notch in the driving element of the clutch 3.4 as shown in Fi 1.1:.

A suitable guide means for the brushstrip. to is momite lon a plate BA secured to the base 20,. this guide means being in proper position for guiding the strip toward the winding mechanism i h. w ll e ully d er bed. As best shown in Figs. 4 and 6 thereare two superposedhcrizontal plates. 52 and 5,3v wh-ieh. are. grooved adjacent their right edges for receiving and. fitting the channel member l2, oi the 7 strip. The upper plate 63 is normally pressed downwardly against the channel. member by springs. 64, 64, so. that the platesv frictionally engage the channelimember toresist movement thereof. A manually operable lever is provided having a cam, 65 at its lower end. When. the lever is in the position shown by full. lines in. Fig. 6. the pp r ate 53 is slightly raised opposition to the

springs

65, 64 so that the strip 10' is freely, movable. When the lever is inthe position. shown bydotted lines the springs are permitted to act to cause frictional engagement of the plateswiththe-channel; member of the strip as previously: described.

The lower plate 62 is connected with a bracket 671 for pivotal: movement abouta vertic l, idslat as. The said; bracket, to; isonnec d i .sub stantially ve ticalstrut ilr m v nt ab ut a horizontal; longitudinal axis. at 10., The lower end ofthestrut 6.9 1s connectedwith the plate 61 for pivotal movement aboutthe axis of a transverse pivot pin H. Byl'neans of' screws l2; l2 engaging the plate 6! the strut 69 may be ad'- justed about the axis at 'H and may be locked; in adjusted position. The screws i2; i2 serve" for the adjustment of the plates 52 and- E3" inthelongitudinal direction soas to locate the stripin proper-feeding position.- Spring pressed pins 73, 13 project upwardly: from. brackets lie, 1.41581- cured tozthe plate I51- Thesapinsi abut against the bottomoftheplateli-Z; and: they thustendtm bias the plates 62 and 63 toward: their normal horizontalzpositions.

An abutment. l 6 i is secured; in fixed ;p.osition, on. the driving, memberellli, this; abutment projecting towardgthe right-from the, exposed: end portion, of the aid member.- A ia rlt e-sa d a utment 16 and below the inner end thereof is a stop pin. l?!

Iihe pin is fl ttenedvto,

center of the pin. As shown in Fig. 16 the pin 77 is longitudinally movable in an aperture in the driving member, being biased outwardly or toward the right by a spring I8. The pin TI has a longitudinal slot therein into which a set screw 79 projects. Jhe set screw prevents relative rotation of the pin and also limits outward movement thereof.

As the first step preparatory to the winding of a brush the operator separates the guide plates 62 and 53 by means of the lever 65 and inserts the channel member I2 of a brush strip I0 between the plates. It will be understood that the brush strip I0 is initially relatively long, its length being sufficient for the making of several brushes. The brush strip is moved so that its channel member is below the abutment l6 and so that the front end of the channel member is in engagement with the flat face of the stop pin 17. Then the lever 65 is moved to permit the

springs

64, 64 to apply pressure against the channel member.

A rotatable arbor 80 is provided upon which the brush strip I0 is to be Wound. This arbor is supported independently of the driving member 46 and is rotatable coaxially therewith. The arbor 80 has an exposed end portion at the left and it is longitudinally movable into and out of an engaged position with respect to the driving member 46. As to size and shape the arbor conforms to the required size and shape of the brush I8 which is to be wound. The arbor may be noncylindrical in cross section and it is shown as being generally triangular, but the invention is not limited to this particular shape.

Mounted on the base is bracket 8| which carries a spindle 82 in alignment with the shaft 22 and the driving member 46. The spindle 82 is longitudinally movable and is nonrotatable, the spindle serving to support the said rotatable arbor 80. Rotation of the spindle may be prevented by a key 84 entering a longitudinal groove in the spindle. The spindle 82 is movable longitudinally by means of a manually operable lever 86. As shown, an arm 88 is rigidly secured to the bracket BI, this arm extending toward the right. Toggle links 89 and 90 are pivotally connected with each other at 9|, the link 89 being pivotally connected with the arm 88 at 92 and the link 90 being pivotally connected with the spindle 82 at 93. The said lever 86 is rigidly connected with one of the links, as for instance the link 89. Fig. 4 shows the spindle in retracted position. When the lever 86 is moved in the clockwise direction to the position shown in Fig. 8 the

links

89 and 90 move the spindle 82 toward the left. Fig. 8 shows the center pivotal connection SI of the toggle moved beyond the center line to effect locking.

The arbor 89 has a central bearing recess which receives and fits an extension 96 on the spindle 82, as shown in Fig. '7. The spindle 82 has a circular flange 98 which fits within a circular recess in the arbor 80. An end plate I00 is secured to the end face of the arbor, this plate engaging the said fiange 98. Thus the arbor is supported for rotation with respect to the spindle. In order that the arbor may be initially maintained in a predetermined rotative position for loading, it is provided with a spring pressed ball detent 102 which enters a suitably located depression in the flange 98.

The arbor 80 is provided at its exposed left end portion with two pins I04 and I06. With the driving member 46 and the arbor in their proper rotative positions for'loading the pin I04 is in alignment with the stop pin 1! and the pin I06 is in alignment with a hole I08 in the exposed portion of the said member 46. When the arbor is moved to its engaged position the pin I04 presses the stop pin 11 inwardly and it enters and fits the hole in which the said stop pin is located. The pin I06 enters and fits the hole I08. The pin I04 has a notch IIO therein which has an inclined bottom face as shown by dotted lines in Fig. 9. The front face of the notch H0 is in alignment with the fiat face of the stop pin I'l. The inner or left end portion of the arbor is slightly beveled as shown at I I2.

After the strip I0 has been placed with the leading end portion of its channel member I2 below the abutment I6 and in engagement with the stop pin H as previously described, the lever is moved in the clockwis direction to move the arbor 36 toward the left from the position shown in Figs. 4, 5, 9 and 12 to its engaged position shown in Figs. 8 and 14. The pin I84 forces the stop pin '4'! into the cylindrical member and the pins I94 and I06 respectively enter and fit the stop pin hole and the hole I08. Thus the arbor is connected with the driving member for rotation in unison therewith. As the pin W4 is moved the inclined bottom face of the notch i If! forces the end portion of the strip channel member upwardly, if necessary, so that the beveled portion i 52 of the arbor can pass under the channel member. The leading end portion of the channel member is pinched between the abutment it and the arbor B0, being thus firmly gripped for the subsequent winding operation. The said abutment l6 constitutes means for connecting the leading portion of the channel memher with the arbor.

For cutting the channel member I2 of the strip id after winding, a cutter [I4 is provided which is bodily movable with the arbor 80 during rotation thereof. The cutter H4 is movable relatively to the arbor to cut the channel member and it is shown as being movable transversely for this purpose. When the cutter is movable transversely for cutting it is preferably also movable longitudinally relatively to the arbor into and out of register with the channel member which is to be out. During winding the cutter HA is out of register with the channel member so as not to interfere with winding. After rotation of the arbor to a predetermined limited extent, the cutter is automatically moved longitudinally into register with the channel member and it is then automatically moved transversely to cut the channel member. After cutting, the cutter is relatively moved reversely to the position wherein it is out of register with the channel member.

Preferably and as shown the cutter H4 is carried by the driving member 46 and it is rotatable relatively to the said member about an eccentric longitudinal axis, this rotation providing the required transverse movement for cutting. The left or inner end face of the abutment I6 is curved and it serves as a cutting abutment for the cutter II l. As previously stated, the cutter IE4 is also movable longitudinally into and out of register with the channel member to be cut, and when out of each register it is in a recess H6 in the member 46. The withdrawal of the cutter into the recess i I6 prevents the cutter from interfering with the winding operation.

As shown, the cutter I l 4 is secured in an eccentric position to the inner or right end of a shaft IIB which is mounted in a bearing aperture in aegeaogesie the mernberidfiffor both=rotative and longitudinal movement.

Thismovement of thelever-55 moves the-lever to release A the single revolution clutch in 'the manner previously described. At the same time the --movemen t-of the lever -55 retracts the pin- 5:; tl'rus perznitting t-he lever-1 24 'to move from the positions shown irrFigs; l1 and'12 to the positions showniin Figs. 18 andl l.

'As the arbor 8B is 'rotated by-the=member--45, the strip 56 is wound thereon, the advancing movement of the strip being resisted by' the friction applied by the plates 62 and 63 0f the guide means. dis-the result of the resistance the' strip asitis Wound conforms to the shape of thearbor. 'Ihesaid-plates t2 andt3 move about the pivotal axis at during winding so that the strip is always tangent to'the peripheryofthe triangu- =Iarly=shapedarbor.

Whenthe positionshown in-Fig. 17'- is reached, the lever! 2G again engages the pin 50. By means of the cam face I28 the cutter I It is movedlon- -gitudina1ly into position for cutting the channel member 12 of the: strip. As movement continues, the'cutter Nd isrotated :in the clockwise directionirom'the position shownin'Fig. 17 to the positionshown in -F-ig. 18, the cutter cooperating with the abutment "i5 to'cut' off the wound portion of the strip. As the cutter H t-moves, itnot onlyeuts the stripbut presses the adjacent end thereof downwardly against the arbor 80. The projecting portion-of the bar l'fiil prevents any possible movement of the endof the channel member 12 into thereoess HSas the said'endof the channelmemberis moved from the position shown-in" Fig. 17 to that shown in Fig. 18. When the position shown in--Fig. 1-8 is reached, the tooth Men the lever dii stops rotation of" the several parts.

Then, by means of thE-IGVGI'BB the'operator withdraws the arbor- 8!) to theposition shownin Figs. 4,6, 9 and 12, the-'Woundbrush being then located on-thearbor. "The brush is removed from thearbor manually. The 'ball detent" Hit-maintainsthe-arbor in'the rotative ;position-to which it has been-moved and prevents any accidental displacement'thereof so that it is ready for the next following operation.

*Itwill be seen'that at the completion of'winding, as shownin Fig. 18, theohannel member 52 of the-stripis atthe-upper side of' the-abutment it. For winding thenext-brushthe'endcfthe channel member strip must be transferred to the lower sideof the said-abutment, that is,--to the position shownin' Figs. 8, 11 and 12. To assist in the transfer, 'the p1ates-62 and 63' are moved slightly in the counterclockwise-direotion about the vertical pivotalaxis at"63. "Preferably they are so moved-by means-operated by themechan-ism -which I moves-"the spindle 82- and the arbor 8B to-their withdrawn positions.

Connected with the-lower plate EZis a linlvltll having a longitudinal slottherein. "An arm 132 isr-igidly-secured to the spindle 82, this arm having a reduced end portion which extends into the slot in thelink I30. When-the spindle 82 andthe arbor 843 are withdrawn to the'positionsshownin-Fig;4; the end portion of the arm 162 engages'the ri-ght end of the slot in'the link l-30an'd swingsthe plates 82' and'fi3 and alsothe strip H) in the counterclockwisedirection ;to the angular positions shown in 'thesaid Fig. '4.

The above described angular movement of 'the strip permits the leading end of the channel member thereof 'tomove 'from'the position at the top of the abutment' i-B as-shown in Fig. 18 to a-position at the right end of the abutment 16 as-shown in Figss l, 5, and119. Then the operatormoves the'1ever -65 t0 separate thep1ate 63 from the platet62 andimanuallyashiftsthe channel member of the strip from the position shown in Figs. 4, and 19 to that shown in Figs. 8, 11 and 12. The leading end of the channel member is engaged with the stop pin 11. When the channel member is shifted as last above stated, the guide plates 62 and 63 are swung in the clockwise direction, such movement being assisted by a spring I34 connected with the upper plate 63. The spindle 82 is free to be moved slightly toward the left by the arm I32. With the channel member in the position shown in Fig. 11, the lever 65 is moved to restore the pressure of the plate E53 against the plate 62 and the machine is ready for the winding of the next following brush in the manner previously described.

As the result of the inherent resiliency of the channel member l2 of the strip and as the result of the action of the cutter I M, the adjacent ends thereof after winding may be-somewhat separated at the completion of winding and cutting, and a subsequent pressing operation may be necessary. For this purpose a plate I36 is mounted on the bracket 8| this plate carrying two abutments I38, I38 having an angle between them corresponding to the required angle between the two longer sides of the completed brush. The plate I36 is longitudinally slotted at I40, and an extension I42 of the pivot pin 93 extends through the said slot. After the winding of a brush and after the withdrawal of the arbor Bil, the parts are in the positions shown in Fig. 4, the pin extension MZ being near the right end of the slot M0. The wound brush is placed on the plate l36 between the abutments I38, I38 as shown in Fig. 4, the pin extension M2 being within the space bounded by the wound channel member [2.

When the parts are moved from the position shown in Fig. 4 to the position shown in Fig. 8 the arbor is moved toward the left as previously described for the winding of another brush. When the parts are so movedthe pin extension 142 moves toward the left in the slot I 40. As the pin extension so moves, it engages the narrow end portion of the wound brush to force the brush between the abutments I38, I38. This serves to press the ends of the channel member toward each other into their proper final positions.

When the parts are restored to the positions shown in Fig. 4, the pressed brush is removed and the next following brush is put in place for pressing.
