WILLARD G. LIFE, OF SYRACUSE, NEW YORK.

BROOM- EWING MACHINE.

Application filed October 4, 1904:.

1 '0 all whom it may concern:

Be it known that I, l VILLARD G. LIFE, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Broom-Sewing Machine, of which the following is a specification.

This invention has for its object the production of a broom-sewing machine, which is especially simple in construction and particularly durable and effective in use; and to this end, it consists in the novel combinations and devices hereinafter set forth and pointed out in the claims.

In describing the invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

The illustrated embodiment of this invention, comprises a main frame 1, a vise 2, and sewing and feeding mechanisms. As is apparent, the frame 1 is of any desirable form, size and construction. The vise 2 usually comprises opposing

upright jaws

3, 4, and a broom-support. Said jaw 3 is shown, Fig. 2, as secured at its intermediate portion to the frame 1 by a horizontal pivot 5 upon which the jaw 3 moves to and fro, or in opposite directions from front to rear of the machine and toward and from the needlepath. A suitable spring 6, Fig. 2, is connected to the frame 1 and the lower end of the jaw 3 and subjects the vise to an increasing resistance when moving in either direction beyond its intermediate position, thus storing energy in the spring 6 which tends to move the vise in opposite directions to said intermediate position. This spring and the means for connecting the same to the frame and the vise form no part of my present invention, and as they are fully shown and described in my prior Patent 718,263, dated Jan. 13, 1903, it is thought unnecessary to further describe the same herein.

As best seen in Figs. 4 and 5, the 4 is movable laterally toward and from the jaw 3 and is provided at its lower end with lateral extensions 7, Figs. 2 and 5, secured by a pivot 3 to the jaw 3. The means for moving the .jaw 4 laterally, as illustrated, consists of two cams 9 and engaging means 10, the cams 9 being fixed to the ends of a common shaft 11 j ournaled in the fixed jaw 3 and forming part of a manually-operated actuating member 12, and the engaging means 10 consisting of pivoted slides, Figs. 4, 10 and 11, which are supported on the ends of a shaft carried by themovable jaw 4 and engage camways in the opposing sides of the cams 9. The movement of the jaw 4 laterally from the jaw 3 may be limited by any desirable means, not illustrated, normally fixed to the frame 1.

The broom-support, as preferably constructed, consists of opposing engaging parts 13 for clamping the broom independently of the

jaws

3, 4, attaching parts 14 supporting the parts 13, and means for moving the. attaching parts and the engaging parts carried thereby toward and from each other. The engaging parts 13 are movable independently of the

jaws

3, 4, toward and from a line substantially coincident with the axis of the broom when clamped by said jaws, and in a direction at substantially a right-angle to the line of movement of the jaw 4 and the plane in which the

jaws

3, 4, compress the broom. These parts 13 are pivoted intermediate of their ends at 15 to the attaching parts 14, are movable on their pivotal axes independently of said parts 14, and are usually formed with curved upper faces and with upper and lower

engaging surfaces

16, 17, arranged, respectively, above and below the pivots 15, the lower ends of the engaging parts 13, provided with the surfaces 17, being comparatively thin and formed of spring material, and being movable or yielding independently of the upper ends of said parts 13, when engaged with the broom. In the preferable construction of my broom-support, the attaching parts 14 are mounted upon the upper ends of levers 13 pivoted intermediate of their ends to a supporting frame 19 carried by the fixed jaw 3. These parts 14 are adjustable lengthwise of the upper ends of the levers 18 forming guides for said parts, and are held in their adjusted position by suitable clamping means, as screws 20. It is thus apparent that the attaching parts 14 are movable in a plurality of directions relatively to the

jaws

3, 4.

The means for moving the attaching parts and the engaging parts carried thereby toward and from each other, consists of the levers 18, and means for rocking said levers on their pivots, relatively to the

jaws

3, 4, and the frame 19, said means being here shown as a spring 21, reciprocating mem bers 22 and cams 23. The spring 21 is interposed between the opposing faces of the lower ends of the levers 18 and forms means for yieldingly forcing the parts 13 into engagement with the broom independently of the vise-

jaws

3, 4. This spring 21 may be supported on a rod 24 connecting the lower ends of the levers 13, and in such event is carried by said levers 13. The reciprocating members 22 are guided in the jaw 3 in a plane substantially parallel to the shaft 11, and the opposing or inner ends thereof are engaged with the outer faces of the lower ends of the levers 18 for moving the engaging parts 13 from. the broom independently of the vise-

jaws

3, 4. The outer ends of the reciprocating members 22 are engaged by the cams 23 which generally consist of camsurfaces provided upon the opposing surfaces of the cams 9 previously described. As will be apparent to those skilled in the art, the cams 23 are so arranged relatively to the camways for receiving the engaging means 10, that when the cams 9 coact with said means 10 to open the opposing jaws of the vise, the cams 23 move the reciprocating members 22 endwise toward each other, and hrough the medium of the levers 18 force the engaging parts 13 from the broom. As the cams 9 commence their reverse move ment for closing the opposing

jaws

3, 4, of the vise, or in other words, for moving the jaw 4 laterally toward the jaw 3, the cams 23 permit the reciprocating members 22 to move outwardly under the influence of the spring 21, and, consequently, saidspring yieldingly engages the parts 13 with the broom, it being understood, however, that the broom is operatively engaged by the parts 13 before the jaw 4 commences to compress the broom against the jaw 3. Since the broom-smiport is solely supported upon the fixed jaw 3, the jaw 4 moves independently of said broom-support and preferably in a direction at substantially right-angles to the line of movement of the engaging parts 13 toward and from each other.

A broom-support having engaging parts constructed and actuated, as described, is particularly applicable for supporting brooms having short handles of ununiform shapes and sizes, as brush-brooms, since said broom-support firmly engages such handles and holds the same in the desired position.

In the preferable construction of this invention, the broom-support is movable, as a whole, relatively to the vise-

jaws

3, 4, downwardly and upwardly lengthwise of a line substantially coincident with the axis of the broom, in order that said support may hold the broom in proper position to receive successive rows of stitches. As here illustrated, the broomsupport moves downwardly by gravity, and is manually controlled in such movement by a rack 25 se' cured to said broom-support by a clamping member 26 and an eccentric sleeve 27, a pair of

pawls

28, 29, engaging the rack 25, and earns 30, 31, provided on the shaft 11 and coacting with the

pawls

28, 29, to permit the broom-support to feed downwardly step by step, as the shaft 11 is rocked to and fro by the actuating member 12. W hen the broom-support has reached the limit of its downward movement, it may be returned by rocking the actuating member 12 on its axis beyond its position assumed when said member has forced the jaw 4 to the limit of its outward movement, whereupon a crankarm provided on the shaft 11 engages a loose sleeve 33 carried by said shaft 11 and connected by a link 34 to the rack 25, and forces said rack upwardly to its elevated position for holding the broom in position to receive the first row of stitches. The means for controlling and effecting the movement-of the broom-support, as a whole, vertically relatively to the vise-j aws is fully shown and described in my aforesaid Patent 718,263, and further description thereof herein is deemed unnecessary.

Although the described broom-support is particularly simple in construction and effective in operation, other devices may be substituted therefor, as those seen in Figs. 32 to 37 inclusive, the broom-support illustrated in Figs. 32 to 35 comprising reciprocating attaching parts 35 and engaging parts 36 adjustably secured thereto and provided with yielding lower ends 37, and the support shown in Figs. 36 and 37 being provided with a tubular frame 38 and a plurality of inwardly-projecting radial spring arms 39 having outwardly-yielding free ends forming broom-engaging parts.

As illustrated, l have provided a banding needle 40 and sewing mechanism, the latter comprising stitclrforming needles 41, 42, loopers 43, 44, and a band-lifter 45. Said banding needle 40, Figs. 12, 13 and. 14, is preferably fixed to one end of a part or lever 46 which is provided at its other end with a hand-piece 47, and is pivoted intermediate of its ends at 48 to a support 49 movable with the vise and reciprocallymovable rectilinearly relatively to said vise in a guide or socket 50 in the movable jaw 4. A gage 51 is fixed to the part or lever 46 in prmrimity to the needle 40, and is thus movable with the vise and the needle. The free end of the gage projects laterally beyond the point of the needle, and its other end is adjustable rectilinearly on the lever 46 in any suitable manner toward and from the needle 40, and is held in its adjusted position by clamping screw A spring 53 moves the part or arm 46 relatively to the broom-vise and the support 49, and a spring 54 movable independently of the spring 53 forces the support 49 and the parts carried thereby relatively to the vise to their initial positions.

in the use of my banding needle, the operator grasps the hand-piece 47 and moves the same in a line parallel to the path of movement of the support 49, thus forcing said support and the parts carried thereby rectilinearly relatively to the vise against the action of the spring 54 until the projecting free end of the gage 51 is substantially coincident with the plane of the front edge of the broom clamped by the

aws

3, 4, being preferably engaged with said front edge, whereupon the needle 40 is in Opera tive position. The operator, while still grasping the hand-piece 47, swings the lever 46 on its pivot relatively to the vise and the support 49, thus moving the needle in a direction at an angle to its reciprocal movement and forcing the free end thereof through the broom. A. banding cord is then engaged with the needle 40 and is drawn thereby through the broom upon the return of the needle. After the engagement of the banding cord with the needle 40, the operator releases the hand-piece 47, whereupon before either of the needles 4-1, 42, engage the broom the springs 43, 54, automatically rock the lever 46 relatively to the support 4. 9 and thus return the needle with the banding cord through the broom, disengage the needle 40 from the broom, and move the support 49 to its initial position. It will be understood, however, that the operator, may, if he prefers, return the needle 40 and its support by hand.

The needles 41, 42, the loopers 43, at, and the. means for supporting and actuating said parts constitute the stitch-forming mechanism of my machine, but said mechanism is substantially identical with that shown and described in my prior Patent, No. 718,268, and hence description thereof herein is deemed unnecessary, particularly as it will be apparent to those skilled in the art that any suitable stitch-forming mechanism may be. employed in this machine.- The bandlifter 15 is also substantially the same as the like part in said patent and forms no part of this invention and, consequently, description thereof is omitted.

The feeding mechanism preferably comprises a driven member 55, Figs. 2 and 16, a driving member 56 and a driving element 57', for moving the member in reverse directions for effecting, respectively, forward and retrograde movements of the vise, and a driving means 58, Figs. 2 and 26, having a part 59 adjustable for controlling the amount of movement of the vise. As illustrated, the driven member 55 consists of a screw revoluble about an upright axis and constantly meshing with a rack 60 fixed to the vise and arranged substantially parallel to a line coincident with the axis of the broom when clamped by the vise. As will beapparent to those skilled in the art, the member 55 is thus revoluble in reverse directions as the vise moves to and fro, and the peripheral threads or shoulders thereof tend to hold the vise in its adjusted position. The driven member 55 is shown as fixed to a shaft 61 which is reversely-revoluble with said member 55, is journaled in any de sir-able bearings 6:2, and is provided with an antifriction thrust-bearing 63 of any suitable construction for resisting the tendency of the member and its shaft 61 to move endwise when feeding the vise step by step during the sewing of the broom.

As here illustrated, the driving member 56, Figs. 16, 17 and 18, consists of a pinion. which is concentric with the driven member 55, is supported by the shaft 61, is loose on said shaft, being journaled on an upwardly projecting hub 61 of the driven member 55, and is movable in reverse directions by a reciprocating rack 65 constantly meshing therewith. A suitable ratchet-device is iriterposed between the

members

55, 56, for moving the driven member 55 with the member 56 in one direction, and permitting said member 56 to move backwardly relatively to the driven member. As shown, this ratchet-device comprises a ratchetwheel 66 and pawls 67, the wheel 66 consisting of a projecting flange on the driving member 56 arranged in a socket 68 extending inwardly from the upper face of the driven member 55, and having peripheral ratchet-teeth, and the pawls 67 being journaled in the driven member 55 on axes substantially parallel with the axis of the shaft 61, and having their upper ends provided with lateral extensions 69 movable in the socket 68 and coacting with the teeth of the wheel 66, and having their lower ends extended beneath the contiguous portions of the driven member 55 and provided with lateral extensions 70 arranged beneath the extensions 69 and substantially parallel thereto. One of the pawls 67 is normally operatively engaged with one of the teeth of the ratchet-wheel 66 for rotating said wheel, and the faces of the other pawls, for coacting with the teeth of said wheel to rotate the same, are dissimilarly separated from the contiguous teeth of the ratchet-wheel, as best seen in Fig. 17. The portion of the driving member 56 provided with the teeth meshing with the rack 65 projects above the socket 68 and a ring 71, Figs. 16, 21 and 22, which ring surrounds the driving member 56 and forms a cover for the portion of the socket 6S encircling said member 56, the inner portion of the ring being arranged in an annular groove 72 formed in the driving member 56 between the gear and ratchet teeth thereof. Suitable springs 78, Fig. 16, encircle the lower projecting ends of the pawls 67 and hold said pawls in engagement with the ratchet-wheel 66.

In order to permit the driven member 55 to move backwardly relatively to the driving member 56, the pawls 67 are forced from operative engagement with the ratchetwheel 66 by any desirable means, as a sleeve 7 4t loosely encircling the shaft 61 and movable lengthwise thereof, the upper end of said sleeve being provided with an inclined surface which forces the extensions 70 of the pawls 67 outwardly as the sleeve is elevated and thus disengages the extensions 69 of said pawls from the teeth of the ratchetwheel 66. The upper end of the sleeve 74 provided with the surface 75 is usually formed separable from the underlying portion of said sleeve and is mounted on an antifriction thrust-bearing 7 6 which reduces to a minimum the friction on the parts when the pawls 67 are held out of operative position. The means for engaging the sleeve 74 with the extensions 70 of the pawls 67 may consist of a lever 77 pivoted intermediate of its ends to the frame 1 and having one end provided with a treadle 7 8, and its other end provided with an upwardly-extending arm 7 9 pivotally connected to a collar 80 surrounding the sleeve 7 4 and having its opposite portion pivoted at 81 to a bracket 82 on the frame 1. Contiguous surfaces of the sleeve 7 1 and the collar 80 are connected by suitable pivotal connections, as trunnions 88, Fig; 16, projecting from opposits sides of the sleeve 75 and journaled in the collar 80. As the treadle 78 is depressed, the sleeve 7%. is moved upwardly lengthwise of the shaft 61 and forces the pawls 67 out of engagement with the ratchet-wheel 66, thus preventing the transmission of motion from one of the

members

55, 56, to the other by the ratchet-device and permitting the driven member to move baclqwardly relatively to the driving member, as when the vise is being returned. As best seen in Fig. 2, the rack 60 fixed to the vise is generally provided with a shoulder 8&1 which, as the vise reaches the limit of its advance movement, encounters a shoulder 85 on the arm 79 and moves the sleeve 74.- upwardly, thus forcing the pawls 67 from operative position.

By the use of the described ratchet-device, and the means for forcing the pawls of said device from operative position, the driven member is propelled in one direction with the driving member 56, and either of said members is permitted to rotate in the reverse direction relatively to the other. It is thus possible to constantly engage the driven member with the vise, and to dispense with means for disengaging these parts. Moreover, the ratchet-pawls, arranged as shown and described permit of minute adjustments of the feed of the vise.

The driving hand-actuated element 57 facilitates the return of the broom-vise to its initial position by moving the driven member in the opposite direction to that in which said member 55 is driven by the member 68. This driving element 57 is fixed to the shaft 61 and constantly meshes with a reciprocating rack 86 guided in the frame 1 and connected to the lower end of a lever 87 pivoted intermediate of its ends at 88 to the vise above the pivot 5 for said vise, and having its upper end provided with a hand piece 89. The lever 87 serves as a convenient means for forcing the vise in either direction, and by connecting said lever to the vise and to the driving element as shown and described, the movement of the vise is greatly facilitated.

The illustrated embodiment of this inven tion is provided with friction-means for holding the vise in its adjusted position when moving step by step, such means consisting of a lower friction-collar 9.0 fixed to the shaft 61, and an upper friction-collar 91 loose on the shaft 61 and movable lengthwise thereof and usually provided on the lower face of the sleeve 74 which sleeve may, if desired, constitute said upper collar. The weight of the sleeve 74 may be utilized as the force for engaging the

collars

90, 91, but I prefer to augment the action thereof by an additional weight 92, Fig. 2, connected to the lever 77. lVhen the vise is feeding step by step, the

frictioncollars

90, 91, are in engagement and hold said vise in its adjusted position, and whenever the treadle 78 is depressed, or the shoulder 84: movable with the *ise is engaged with the shoulder 85, the collar 7 e in addition to forcing the pawls 67 from operative position, simultaneously relieves the vise from said friction-means. A comparaively light weight for engaging the

collars

90, 91, is suliicient, since by utilizing a screw to move the vise step by step, it is pos sible to hold the same in its adjusted position by means which subjects said vise to but little additional friction and does not materially retard the forward feeding thereof.

In the preferable construction of my invention, the driving means 58 is mounted on the main shaft 98, Fig. 2, and the adjustable part 59 of said means, Fig. 56, for regulating the length of the advance steps of the vise during the sewing of the broom, is pivoted intermediate of its ends to the main body of the means 58 by a pivot 94; arranged parallel to the axis of the means 58. Said main body of the driving means 58 is provided with a peripheral cutout 95, Figs. 25 and 26, and with peripheral engaging faces 96, 97, arranged one in advance of the other and in advance of cutout, the face 97 being substantially equidistant throughout its length from the axis of the means 58, and the face 96 being arranged in advance of the face 97 and extended inwardly toward the axis of the means 58 from its rear end, and being essentially cam-shaped. The advance end of the adj ustable part 59 is arranged in the cutout at one side of the rear end of the engaging face 97, and the rear end of said part 59 projects into a peripheral groove 98 in the face 96 and the advance end of the face 97, and is adjustable toward and from the axis of the means 58. As clearly seen in Fig. 26, the outer edge of the portion of the adjustable part 59 in alinement with a radial line passing through the axes of the shaft 93 and the pivot 9% of the adjustable part 59 is substantially concentric with said pivot 94, and is also substantially tangent with the rear end of the face 97 The outer edge of the remaining portion of the part 59 is of substantially the same radius as that of the face 97, and when said part is in operative position, Fig. 26, is arranged substantially cam-shaped relatively to the main body of the driving means and within a circular line 99, coincident with the face 97, but when the part 59 is moved outwardly to its extreme limit into inoperative position, Fig. 24', said outer edge is substantially concentric with the axis of the shaft 93 and coincident with such circular line 99. A suitable spring 100 engages the end of the adjustable part 59 at one side of the rear end of the face 97 for returning said part 59 to its inner position, and a reciprocating actuating member 101 engages the inner edge of the adjustable part 59 between the pivot 9a and the groove 98 for forcing the main portion of said part 59 outwardly about said pivot 94 The reciprocating actuating member 101 is usually wedgeshaped, is revoluble with, and suitably guided in, the main body of the driving means 58, and is pivotally connected at one end to a collar 102 reciprocally movable along the shaft 93. The described means for moving the adjustable part 59 outwardly is, however, only one of many structures which may be used for this purpose.

Motion is transmitted from the driving means 58 to the rack by an intermittently movable power-transmitting member 103, here illustrated as pivoted intermediate of its ends to a bracket 10 1, and as having one end provided with a roller 105 constantly engaged with the periphery of the driving means 58, and its other end rounded and constantly engaged with one end of the rack 65. The member 103 moves the rack 65 in one direction for actuating the driving member 56 to advance the driven member 55and the vise connected thereto a single step, and a suitable spring 106 moves said rack in the reverse direction. It thus follows that the spring 106 holds the member 103 in engagement with the periphery of the driving means 58. Providing the adjustable part 59 is set to effect the predetermined movement of the vise, the upper end of the power-transmitting member 103 moves toward the center of the driving means 58 immediately after the adjustable part 59 is first engaged with the roller 105 the inner position of the member 103 being its starting position, and when the cam-shaped peripheral face 96 of the driving means 58 is engaged with said roller 105 the powertransmitting member 103 is reversely moved and effects the desired advance of the vise. Just after an advance step of the vise, the power-transmitting member 103 engages the face 97, and is then in a constant or nonvariable initial position, being held in such position by the face 97 which prevents inward movement of the roller 105, and by the spring 106 engaging saidroller with the face 97. It is therefore apparent that the face 97 determines the initial position of the power transmitting member 103. When, during the sewing of a lot of brooms, the part 59 is adjusted a number of times relatively to the main body of the driving means 58, the power-transmitting member 103, as said driving means rotates, moves inwardly toward the axis of the shaft 93 from its initial position dissimilar distances, as determined by the position of the adjustable part 59, and is moved backwardly to such position by the face 96, thus determining the length of the advance steps of the vise. Consequentl g'tlie adjustable part 59 limits the movement of the upper end of the powertransmitting member 103 inwardly toward the axis of the driving means 58 and thereby regulates the outward or return movement of said upper end to its initial position. It is thus apparent that the part 59 and the surface 97 coact, respectively, to al low the upper end of the powertransmitting member 103 to move inwardly toward the shaft 93 to its starting position and to force said upper end outwardly from the shaft 93, and that the position of the part 59 varies the travel of said upper end, and therefore regulates the length of the ad vance steps of the vise.

By those skilled in the art, it will be understood that by constantly engaging the power-transmitting member 103 with the driving means 58 and the rack 05 in mesh with the driving member 56 connected to the vise, the liability of lost motion and ar of the vise-feeding parts is reduced to a minimum and especially minute changes in the length of the advance steps of the vise may be effected.

My present invention is not limited to a broom-sewing machine, in which the driving means for regulating the length of the advance steps of the vise is provided with an adjustable part movable inwardly from its initial position for determining the length of the steps of the vise, and in order that this may be apparent, 1 have at Figs. 38 to 42, inclusive, shown a modified construction of driving means, having its adjustable part 58 movable outwardly from an initial position, to give the desired movement to the power-transmitting member 103, and advance the vise by steps of the predetermined length. In this modified construction the adjustable part 59 consists of a disk on the shaft 93, the eccentricity of which to the shaft 93 may be varied by the wedge 101. In varying the eccentricity of the part 59 in this construction, said part moves in a right line relatively to the axis of the shaft 93 against the action of springs 100.

As will be obvious to those skilled in the art, the means, as the collar 102, connected to the adjustable part 59 for varying the position thereof and regulating the advance steps of the vise, may be adjusted and held in the predetermined position by any suitable means. A. particularly desirable construction of said means comprises a lever or power-transmitting member 107, a reciprocating part 108. and an adjustable part or power-transmitting member 100; the lever 10? being pivoted intermediate of its ends, and having one end engaged with a flat sun face 110 on the movable vise-jaw 1, Figs. 2 and 3, and its other end provided with a lengthwise slot 111; the reciprocating part 108 being movable lengthwise of a guide 112 in-a direction substantially parallel to the shaft 93 and the line of reciprocation of the member 101, and being formed with a depending slotted arm or fork 113 engaged with the collar 10.2; and the powertransn'iitting member 109 being adjustable lengthwise ot the line of reciprocation of the part 108 and having one end adjustably fixed by a screw 11 1 to said part 108, and its opposite end formed with alateral extension 115 arranged substantially parallel to the rear end of the lever 107 and provi ded with a lengthwise slot 116 alined with the slot 111. Said extension 115 is connected to the rear end of the lever 107 by an adjustable connection comprising a pin 11'? having one end of angular cross-section guided in the slot 110 and its other end formed cylindrical and encircled by a sleeve 118 of angular cross-section guided in the slot 111. Any desirable clamp, as a screw 119, holds the pin 11'? in its adjusted position relatively to the extension 115. A suitable spring 120 is connected to the frame 1 and the power-transmitting member or le ver 107 for holding said lever in engage ment vith the surface 110 and for also actuating the

parts

107, 100, 108, 102, to move the reciprocating member 101 to its posi-- tion assumed in Fig. T he movement of said

parts

107, 100, 108, 102 may be limited by any desirable means, as a pair of uprights or standards 121 between which the part 108 is movable. The described connection between the reciprocating collar 102 and the movable vise-jaw & is readily as- SQHIlJlGCl and can be adjusted at will. It will be understood, however, that other con nections may be used for this purpose, and at F' 1 1, l have shown a slightly modeled construction of this feature of my inve. tion conuarising a longitudinally-adjustable link 1.22 having its opposite ends pivotally connected to the lever engaging the vise and the reciprocating part coacting with the collar.

To those skilled in the art, it will. understood that after the operator has adji l the connections between the vise-jaw d and the collar 102 by moving the part 100 and the connection between the lever 107 and said part 109, the thickness of the broom, which determines the distance between the jaws 3, 1, causes the movable jaw il to vary the position of the end of the lever 107 engaged with said jaw, and to thus control the adjustment of the wedgeshaped member 101 against the action of the spring 120, d through the medium of the parts 107, 109, 108, 102, and thereby regulate the length of the step by step ad vances of the broom and the length of the stitches In other words, if a thick broom is interposed between the vise-jaws, the at will actuate the parts 107, 109, 108, 102, 101, to more the part 59 against the action of the spring toward its position assumed in Fig. and to properly adjust the position ot the part 50 so that the advance steps of the vise will be sufiiciently long, whereas it a thin broom is clamped by the jaws 3, i, said jaw 1 will permit the spring 120 to iieversely move these parts 107, 109, 108, 102, 101, and adjust the part 59, so that the steps of the rise will be shortened to produce the desired length of the stitches.

The construction and operation of this broom-sewing machine will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it will be obvious that the construction. and arrangement of the component parts thereof may be more or less varied without departing from the spirit of this invention.
