Specification of Letters Patent.

Patented May 5, 1914.

Application filed April 18, 1910. Serial No. 556,218.

To all whom it may concern Be it known that I, HENRY IVEBER, Jr., a citizen of the United States, residing at Chicago in the county of Cook and State of Illinois have invented certain new and useful Improvements in Work- Feeding Mechanism for Stitchingdda-chines, of which the following is a specification.

This invention relates to improvements in work feeding mechanism for stapling or stitching machines, particularly adapted for use in machines for stapling boxes of considerable length, and one of the objects of the invention is to provide improved means for feeding the work to the stapling mechanism and improved means for varying the degree of movement of the feeding mechanism.

A further object is to provide improved means for adjusting the work feeding mechanism. with respect to the work support to accommodate work of different thicknesses, and for maintaining a uniform pressure of the feeding mechanism upon the work in any of its adjusted positions.

A further object is to provide an improved support for the work and improved means for raising and lowering the support with respect to the stapling mechanism,

A further object is to provide an improved guide for directing the work to the stapling mechanism, and improved means whereby the guide may be adjusted to accommodate the work of varying widths.

A. further object is to provide an improved gage for positioning the work upon the support.

A further object is to provide an improved machine of this character which will be simple, durable and cheap in construction, and effective and efficient in operation.

To the attaimnent of these ends and the accomplishment of other new and useful object-s as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating an embodiment of the invention, and in whi-ch Figure l is a front elevation of a stapling machine showing an attachment applied thereto constructed in accordance with the principles of this invention. Fig. 2 is a top plan view of Fig. 1. Fig. 8 is a sectional view on line 3 3 of Fig. 1. Fig. 4 is an enlarged detail elevation of the operating mechanism for the feeder. Fig, 5 is an enlarged detail sectional view showing the support for the feeding wheel and the means for adjusting the same with relation to the work support. Fig. 6 is a detail sectional view on the line 66 of Fig. 3. Fig. 7 is a detail sectional view on line 77 of Fig. 1. Fig. 8 is a detail sectional view on line 8-8 of Fig. 4.

Referring more particularly to the drawings and in the present exemplification of the invention, the numeral 10 designates generally the stapling mechanism which is mounted upon a suitable support 11, and which stapling mechanism receives its motion from a pulley wheel 12 adapted to be driven from any suitable source of power. Spaced from the support 11 and to one side thereof is another support 13 which may be connected with the support 11 in any suitable manner, preferably by means of a connection 1 1 at the base thereof. This support 13 is provided with a head 15 and a work supporting arm 16 is pivotally mounted upon the head 15 as at 17 Work support 16 may be of any desired length and configuration, but is preferably in the form of a narrow bar, as shown more clearly in Fig. 2, with its forward end 18 terminating at a point slightly beyond the stapling mechanism 10. The rear end 19 of the work support 16 projects for any desired distance beyond the support 13, and is provided with a slot 20 (shown more clearly in Fig. 7) through which a fastening device 21 passes. This fastening device also passes through the head 15 of the support 13, and the portion 22 of the fastening device 21 which passes through the slot 20 is of a diameter somewhat smaller than the width of the slot, so that the work support 16 may be adjusted about its point of pivotal support 17 to raise and lower the forward end thereof with respect to the stapling mechanism.

Connected to the rear extremity 19 of the work support 16 by means of a pivot 23 is a bar or rod 24, the free extremity 25 of which is screw-threaded. A similar bar or rod 26 is pivotally connected as at 27 to a portion 28 of the base of the support 13, and the free extremity 29 of this bar or rod 26 is screwthreaded. The threads on the extremity of one of the bars or rods 24, 26 are right hand threads, while the threads on the extremity of the other bar or rod are left hand threads, and

these threaded extremities are connected by means of a collar or nut 30, around which is arranged a hand operating wheel 31. \Vhen the hand wheel 31 is rotated, the nut or collar 30 will draw the rods 24, 26 toward each other, or separate the rods to raise or lower the extremity 18 of the work support 16, according to the direction of rotation of the hand wheel, and in. order that this hand wheel and collar may serve to counterbalance the work support, they are constructed of heavy material.

In order to regulate the adjustment the nut or collar is preferably provided with graduations 32, and an index or pointer 33 is supported preferably by one of the bars or rods 24 to cooperate with these graduations 32.

The platform or table 34 is provided for holding the supply of work, and is preferably arranged adjacent the standard or upright 13, and rests upon the head 15. A bracket 35 may also be provided which projects laterally from the head 15 to assist in supporting the table.

A support 36 is mounted upon the upright 11 and an additional support 37 is mounted upon the head of the stapling mechanism. Journaled in the support 36 is a shaft 38, which is provided with a gear wheel 39 (see Fig. 4) and the forward extremity of this shaftprojects beyond the support 36 and is enlarged as at 40 to form a tubular extension. This tubular extension is bifurcated as at 41 for a purpose to be hereinafter set forth. A second shaft 42 is journaled in the support 36 and a gear wheel 43 is secured to one end thereof. This shaft 42 is arranged adjacent and parallel with the shaft 38, so that the gear 43 will mesh with the gear 39 on the shaft 38. A ratchet wheel 44 is also secured to the shaft 42 and is adapted to impart rotation to the shaft 42 when rotated. An oscillating arm or member 45 is pivotally supported by one end, preferably upon the shaft 42, and a ratchet dog 46 is pivotally mounted upon the arm or member 45, so that when the latter is oscillated, it will cooperate with the teeth of the ratchet 44 to move the latter in one direction when the arm or support is moved in one direction, and to ride over the teeth when the arm or support is moved in the opposite direction. An elastic member 47, such as a spring, is provided, which tends normally to hold the ratchet dog in engagement with the ratchet teeth. Any suitable means may be provided for oscillating the arm or support 45, and a suitable and efficient means for accomplishing this result comprises a shaft 48 which is mounted in suitable bearings 49 on the support 36. Secured to one extremity of the shaft 48 is an arm 50 which is provided with a slotted extremity 51 into which a pin or lug 52 projects, and this pin or lug is supported by the arm or member 45, so that when the shaft 48 is rocked within its bearings, the arm 50 will be correspondingly rocked, and this movement of the arm will impart an oscillating movement to the arm or support Secured to the other end of the shaft 48 is another arm 53 which is preferably arranged opposite to the arm 50. Journaled to the extremity of the arm is an antifrict-ion roller 54 which engages a cam 55 mounted upon the operating shaft of the stapling mechanism, and which cam is sccured for rotation with the pulley 12. \Vhen the cam is rotated, the shaft 48 will be rocked in its bearings, and will through the medium of the arm 50, arm or support 45 and dog 46, rotate the ratchet 44. This ratchet will in turn rotate the shaft 38 through the medium of the meshing gears 43, The anti-friction roller 54 may be held in position to be engaged by the cam in any desired or suitable manner, preferably by means of an elastic member 56, such as a coil spring or the like. This elastic member surrounds a bar or rod 57 with one extremity resting against a head 58 on the bar, and the other extremity against a lug 59 on the arm 50. The free extremity of the bar 57 projects through a bearing 60 on the support 36 and is threaded, as at 61, to receive anut or collar 62. lVhen it is desired to vary the degree of rotation of the shaft 42, the nut or collar 62 may be adjusted to adjust the bar or rod 57 longi tudinally, and this longitudinal adjustment thereof will vary the angle of the arm 53 with respect to the cam 55 to move the antifriction roller 54 on the arm toward or away from the cam, and in order to indicate the degree of adjustment, the rod 57 is provided with a collar 63 having graduations 64 thereon, and an indicator 65 is provided which cooperates with the graduations 64-. The collar 63 is connected for rotation with the nutor collar 62 so that when the latter is rotated, the graduations 64 will be adjusted with respect to the indicator 65.

The support 37 on the head of the stapling mechanism is provided with a tubular portion 66 having a shoulder 67. A bearing 68 is provided with an extension 69, which latter projects into the tubular portion 66 of the support 37. The bearing is supported and connected with the support 37 by means of a rod or member 70 which projects into the tubular portion 66 of the support 37, and is screw-threaded as at 71 and this threaded portion 71. projects into a threaded recess 72 in the extension 69 on the bearing 68 for supporting the bearing. The rod or member 70 is provided with a collar 73 within the recess 66 and is adapted to engage the shoulder 67 and to be held in engagement with said shoulder by means of an elastic member 74, such as a coil spring or the like which surrounds the rod above the tubular portion 66 of the support 37 and one extremity thereof rests against the support and the other extremity against a nut or collar 7 which is secured to the rod by a suitable fastening device 76. With this construction and when it is desired to adjust the bearing 68 with respect to the support 37, all that is necessary is to rotate the sleeve or collar 75, and this will in turn rotate the rod 70. l' hen the rod is rotated, the threaded extremity 71 thereof will draw the extension 69 of the bearing 68 into the tubular portion 66 of the support 37, or force the latter out of the tubular portion, according to the direction of rotation of the sleeve or collar 7o. The elastic member 74: will always tend to hold the collar T3 against the shoulder 67.

Journaled in the bearing (58 is a shaft 7 7 which is provided with a laterally projecting portion 78, in one end thereof (see Fig. 3) and this extremity is adapted to be inserted into the sleeve 40 on the shaft 38, so that the lateral projection 78 will enter the bifurcation in the sleeve. The forward extremity of the shaft 77 projects through and beyond the bearing 68, and secured thereto is a feed wheel 79 which may be of any ordinary and well known construction. This feed wheel 79 is located directly above the top of the work support 16, and is adapted to be moved into engagement with the work as it rests upon the support. When the feed wheel is in engagement with the work and a rotary motion is imparted to the shaft 7 7 from the shaft 38, the feed wheel '79 will be rotated to advance the work, and the degree of rotation of the feed wheel is controlled by the adjustment of the arm 53 through the medium of the collar 62 and the bar or red 57 in the manner as already set forth.

The feed wheel 79 is normally elevated out of engagement with the support 16 by the elastic member 74:, and when the work is in position, the feed wheel is depressed or moved into engagement with the work. Any suitable means may be provided for accomplishing this result. A suitable and efficient means comprises a member 80 which slides through a suitable bearing 81 preferably mounted upon the support 37. The upper extremity 82 of this member 80 is preferably of a hook-shaped formation, the extremity of which engages the collar 75, which latter is preferably recessed slightly to receive the extremity. The other extremity 83 of the member 80 is connected to an arm or lever 84:, one extremity of which is pivotally supported as at 85 to a suitable support, and the other extremity is connected by means of a link 86 to the treadle 87, which latter actuates the clutch mechanism, and which clutch mechanism couples the pulley 12 to the main operating shaft of the stapling mechanism in the ordinary and well known manner not necessary to illustrate. Suflice it to say that the feed wheel 79 is lowered into engagement with the work simultaneously 1 with the throwing in of the clutch for controlling the pulley 12.

In order to regulate the degree of adjustment of the feed wheel 79, with respect to the w rk support 16, an indicator 88 is pro vided which is connected preferably to the bearing 68 and cooperates with graduations 89 arranged on any suitable support, prefe ably the support 37.

The work support 16 may be provided with any number of anti-friction rollers 90, so as not to retard the advancement of the work thereon, and a supplemental support 91 may be provided which is also provided with anti-friction rollers 92. This supplemental support cooperates with the work support 16 and is adjustable laterally with respect thereto, so as to accommodate work of varying widths, and this supplemental support may be supported in any desired or suitable manner, preferably by means of brackets 98, one extremity of each of which is pivotally mounted, as at 9%, to one side of the work support 16 and the other extremities are loosely connected by means of fastening devices 95 to the supplemental. support 91. hen it is desired to adjust this supplemental support laterally with respect to the main support 16, all that is necessary is to loosen the fastening devices 95 and move the supplemental support to the desired position, such motion being permitted by the pivotal action of the brackets 93. After adjustment, the fastening devices may be tightened to secure the parts in position.

In order to direct the work to the stapling mechanism as it is advanced by hand along the work support 16 from the table or platform 34 into position to be engaged by the feeding wheel 79, suitable guides are provided which comprise spaced

horizontal members

96, 97. One of these members 96 is supported from the main support or standard 11 in any suitable manner and extends over the top of the work support 16 and is spaced therefrom. This member 96 is provided with a depending flanged portion 97 which projects below the surface of the work support and adjacent the rear face thereof, and anti-friction rollers 98 are yieldingly supported in the portion 97 so as to engage the portion of the work extending across the rear face of the support 16. The member 96 is provided with a suitable aperture through which the feed wheel 79 projects. The edge 99 of the member 96 adjacent the work as it is advanced toward the stapling mechanism is deflected as shown, and the extremities of the depending portions 9'7 are deflected as at 100 to assist in guiding the work beneath the member 96. The member 97 which eoope'ates with the member 96 is also provided with a deflected portion 101 corresponding to the portion 99 of the member 97 and this member 97 is also provided with a depending portion 102 similar to the portion 97 of the member 96. The extremities of this portion 102 are deflected as at 103 and assist in directing the work beneath the

members

96, 97.

The member 97 is supported by means of bars or rods the free extremities of which slide in suitable guides 105 provided on the support 100, and which support is mounted upon the upright 11. Suitable fastening devices 106 may be provided for holding the member 97 in its adjusted position. One of these bars or rods 10% may be provided with graduations 107 and an indi cator 108 is provided preferably on the member 90 which cooperates with the graduations.

With this improved construction it will be apparent that after the supports and guides have been adjusted, the work may be fed by hand from the table or platform and the deflected or bent extremities of the

members

96, 97 and the

extremities

100, 103 of the depending portions 97 102 will direct the work into proper position with respect to the stapling mechanism. In order to prop e'rly position the work without necessitating accurate adjustment each time a new piece of work is fed, a suitable gage 109 is provided and this gage is mounted for adjustment on the work support 16 and longitudinally thereof. The gage projects above the top of the work support as shown more clearly in Figs. 1 and 2 to form a shoulder against which one edge of the work is adapted to engage and a fastening device 110 is provided for securing the gage in position. Having once adjusted the gage 109, it will be apparent that the work may be readily fed by hand from the table 3st and properly positioned with respect to the stapling mechanism by causing the rear edge of the work to engage and rest against the shoulder formed by the gage 109.

The position in which the staples are inserted into the work with respect to each other may be varied by adjusting the collar ('32 to move the anti-friction roller 54 toward or away from the cam 55. lVhen it is desired to set the staples close together, the anti-friction roller is adjusted some dist ance away from the axis of rotation of the cam, but when it is desired to set the staples farther apart, the anti-friction roller is adjusted toward the axis of rotation of the cam.

With this improved construction, all that is necessary after the parts have been adjusted, and when it is ready to insert staples into the work, is for the operator to take his position with respect to the machine so that he can readily remove the work from the supply and move the work along the work support 10. After the work has been properly adjusted, the t-readle S7 is depressed and the mechanism is operated to insert a staple. After the insertion of each staple, the feeding mechanism will advance the work to the proper position and according to the degree of rotation of the feeding wheel 79 as the machine may be adjusted. By the provision of the

members

96, 97, it will be apparent that after one corner of the work has been inserted thereunder and the operator should release his hold of the work, the work will not fall from the work support to the round, but will be maintained upon the work support by means of the

members

96, 97 and their depending portions 97. It will also be apparent that the elastic member 74 will be always maintained under the same tension, no matter to what position the hearing may be adjusted by the member 70.

In order to prevent the overthrow of the feed wheel 79 an elastic member 111 in the form of a coil spring is provided which surrounds a portion of the shaft 49. between the enlarged portion and the bearing, so as to create a friction on the shaft which will act as a brake to prevent overthrow.

In order that the invention might be fully understood, the details of the foregoing embodiment thereof have been thus spec-illcally described, but
