MARSHALL HENRY PEARSON, OF LEICESTE MACHINERY COMPANY, OF PATERSON,

JERSEY.

R, ENGLAND, ASSIGNOR TO UNITED SHOE NEW JERSEY, A CORPORATION OF NEW FASTENER SUPPLYIN G AND DELIVERING MECHANISM.

Original application filed May 18, 1903, Serial No. 157,555.

Serial No. 607,159.

To all whom it may concern:

Be it known that I, MARsI-IALL HENRY PEARSON, a subject of the King of the United Kingdom of Great Britain and Ireland, residing at Leicester, in the county of Leicester, England, have invented certain Improvements in Fastener Supplying and Delivering Mechanism, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to fastener supplying and delivering mechanism for machines for inserting fasteners in boots or shoes and more particularly to such mechanism for setting eyelets or lacing hooks used in the manufacture of shoes. A device of this character generally comprises a hook or eyelet pot, according to the particular form of fastener to be used, and means for delivering the fasteners from the pot to one or more raceways or chutes which lead to the fastener setting devices.

The present invent-ion is shown as applied to the eyeleting machine illustrated and described in the inventors co-pending application, Serial No. 157,555, filed May 18, 1903, patented January 2, 1912, No. 1,013,215,,from which it has been divided, but this invention is not limited to that particular type of machine illustrated in said co-pending application. In machines of this character it has been common to provide an eyelet pot which is set in an inclined position and delivers eyelets through combs on the lower side thereof to raceways or eyelet chutes. In these machines the eyelet pot is oscillated about an axis below'the pot in order to advance the chutes to the setting devices at the proper time to deliver an eyelet. An example of such a machine may be found in the United States Patent No. 683,488, dated .Oct. 1, 1901, issued to United Shoe Machinery Company, assignee, on an application of the present inventor. It has been found that such construction is objectionable owing to the high speed of operation of the machine which induced a considerable momentum to the pot which has to be overcome at each reversal of the direction of movement thereof. It has also been found that Specification of Letters Patent. Patented June 25, 1912.

Divided and this application filed February 7,

it is inconvenient to feed eyelets to the pot during the operation of the machine.

It is the object of the present invention to overcome these objections.

In accordance with this object one feature of the invention comprises a fastener pot mounted to oscillate about its own axis and adapted to deliver fasteners from lat eral openings toward its ends to the chutes. Anotherfeature comprises the provision of a vessel conveniently located relative to the pot containing a reserve supply of fasteners which may be fed by the operative to the pot at any time that the supply of fasteners in the pot becomes low.

Other features of the invention will beapparent to those skilled in the art from the following description and will be partieularly pointed out in the appended claims.

The invention is illustrated as used in connection with a duplex eyeleting machine having two raceways or chutes leading from the two ends of a double fastenerpot, but it is equally useful in a machine having but a single chute for setting fasteners in one side only of the upper.

The preferred form of the invention is illustrated in the drawings, in which- Figure 1 is a front elevation of the invention as applied to the 'eyeleting machine of the co-pending application hereinbefore referred to; Fig. 2 is a side elevation as viewed from the right of Fig. 1; Fig. 3 is aview of a portion of the parts shown in Fig. 2 showing particularly the punching and eyelet setting devices, the intervening parts being removed; and Fig. 4 is a section of the eyelet poton the line 44 of Fig. 1.

In the embodiment of the invention illustrated in the drawings, a frame N incloses the principal operative parts of the machine, this frame being mounted on a suitable base B to which it is secured in any convenient manner. The frame N is provided with bearings for the main shaft M of the machine upon which are mounted cams which actuate the operative parts. The shaft may be driven by a pulley 139 belted to a suitable source of power.

The work, when the machine is used as a duplex machine, is presented to-the setting devices on opposite sides of a guide plate Gr,

the two sides of the upper being laid against the opposite sides of the guide plate with their edges against edge guides carried by the plate. Wbrk holders H are provided to hold the work in its proper position.

The operation of the machine is the same as described in the co-pending application hereinbefore referred to. The punches P punch two holes in the opposite sides of the upper against the anvil or die plate A, then the punches are retracted from engagement with the material raised to bring the eyelet sets S opposite the holes made by the punches. The eyelet chutes G then present eyelets to the eyelet sets and withdraw. The eyelet sets then secure the eyelets in the holes in the opposite sides of the upper against the anvil or die plate A. The feed frame F is then moved to the leftthe desired distance bet-ween two successive holes, during which feed movement the work is held by the eyelet sets S, the holders H being released during this time from their engagement with the upper. The clamping devices or work holders again engage the material, the eyelet sets are withdrawn and the feed frame returns to its original position when the operation of the machine may be repeated.

The work holders H and the guide plates G are identical in construction and in op eration with the similar parts described in the parent application, Serial No. 157,555, to which reference has been made, and, therefore, no further description of these parts is necessary. Thefeed frome F,which constitutes the support for the punches and the eyelet sets, is mounted to move up and down about the shaft 23. .This movement is imparted through the link 24 and the crank pin 25, as is described in the before mentioned application. The lower part of the feed frame is given its feeding movement by means of the arm 36of the bellcrank lever which is connected with a bar 34 carried by the feed frame. The arm 38 of the bell-crank lever is connected by a link 39 in such a manner as to be actuated from a cam lever 40 which is supported in the frame N. The lever 40 is in operative relation with a cam 42 mounted on the shaft M. The punches and eyelet sets, which are the same as in the parent application, are arranged in the feed frame F oppositeto one another and. on opposite sides of the die or anvil plate A. The punches P are each provided with a shank which is screwed into a hole in the punch slide .44 slidingly mounted in the lower part of the support or feed frame F. The punch slides are each provided with a transverse bearing for the pins 47 The ends of the pins are secured to the lower ends of the levers 48 and 49, which are connected by links 50 near their middle points. The connection of the and the feed frame Fis links 50 with the levers 48 and 49 may be adjusted by means of the catch 54 and the segment 55. The levers 48 and 49 may be actuated by means of the toggle links 60 and 61 which are pivoted to the levers at their upper ends, the toggle links being mounted on the block 62.

The means for actuating the punch operating parts is fully described in the application to which reference has been made. It is sufficient to say that when the block 62 is lowered the punches are positively withdrawn by the breaking of the toggle and when the block 62 is raised they are advanced to perform their punching operation.

The eyelet sets S are mounted in bearings below the punches in the feed frame F. They are carried by slides 72 having abutments 73 which are engaged by the operative ends of the eyelet set actuating levers 74 and 75. The levers 74 and 75 are bellcrank links articulated together at their upper ends (see Fig. 3). The hooks 84 are'attached to the lower ends of the levers to engage the separated to withdraw the eyelet sets from engagement with the material. The lever 7 5 has a cam roll 91 in engagement with the cam path 92 on the cam disk 16 which is secured to the shaft M. For a full explanation and a description of other parts relating to the levers 74 and 75 and the operation thereof, attention is directed to said Patent No. 1,013,215.

The fastener or eyelet pot 111 consists of a substantially cylindrical vessel with plain ends normal to the axis of the cylinder and having a contracted body portion so as to direct. the eyelets toward the ends of the vessel where they are discharged through combs 113 into the eyelet chutes 112. The combs 113 are adjustably supported upon screws 114 which carry adjusting nuts 115 so that the combs may be moved toward and from the bases of the eyelet pot to allow for thinner and thicker headed eyelets. A portion of the upper end of one side of each chute is pivotally attached to the eyelet pot and normally held in position by means of a spring catch which may be opened to dislodge any eyelets which may become lodged in the comb. V

The eyelet pot is supported upon an eyelet pot lever 116 which is provided upon its forward end with a disk 117 (see Fig. 4), to which the eyelet pot is secured; The front side of the disk is transversely grooved and receives therein a feather or tongue which projects rearwardly from the rear base of the pot. The feather 118 is undercut at one of its ends and is projected under a hook 119 secured to the edge of the disk 117 opposite the groove. The diametrically opposite edge of the disk 117 is notched at abutments 7 3 when the levers are 120 to receive the removable locking bolt 121 which projects through the feather 118. The locking bolt is secured in position by a dog nut 122. The eyelet pot lever 116 is mounted upon a hollow shaft 123 carried by bearings 124; and 125 in the frame. The hollow shaft 123 receives the clutch actuating shaft 126 which is connected at its forward end by a tongue and groove clutch connection with a shaft 127 mounted in hearings in the bases of the eyelet pot 111. The shaft 127 carries brushes 201 which sweep the eyelets past the comb so as to deliver them therethrough to the eyelet chutes. The brush actuating shaft 126 is provided upon its rear end with an enlargement 128 which is grooved at 129 to receive a plurality of balls 180 which project beyond the groove in the cavities in the collar 131 by means of which the shaft 126 may be clutched to the collar. This forms what is generally known as a Horton clutch. The rear end of the brush actuating shaft 126 is also provided with a handle 132 by means of which the shaft may be moved to the rear against the action of a spring 133 to disengage the tongue and groove clutch connection between the shaft 126 and the shaft 127. The collar 131 is connected by means of a link 134:, shown in dotted lines in Fig. 1, with an upwardly projecting arm 135 movable with the cam lever 4:0, thus during the operation of the machine the brushes are intermittently advanced during portions of the revolutions by the means described.

hen it is desired to remove the eyelet pot from the machine, the nut 122 is loosened and the eyelet brush actuating shaft 126 is moved rearwardly whereupon the eyelet pot may be slid to the right as viewed in Fig. 1, thereby releasing it from engagement with the disk 117 of the eyelet pot actuating lever 116. The lever 116 is provided with a downwardly extending portion 136 which carries a cam roll which engages the cam surface 137 of the cam disk 16. This is a common form of actuating mechanism, a side elevation of the cam disk 16 and cam surface 137 being shown in Fig. 3 of said Patent No. 1,013,215. A spring, not shown, normally holds the cam roll in contact with the cam disk. By this construction the eyelet pot is oscillated about its axis to periodically advance the raceways or chutes 112 to deliver an eyelet to the setting devices. A latch 138 is provided to hold the cam roll out of contact with the cam surface when it is desired to punch the holes in the work without setting eyelets therein.

. In connection with the eyelet pot there is employed a reserve eyelet supply vessel 202 for supplying eyelets to the eyelet pot when they become low. This vessel is mounted upon the upper part of the frame of the machine and has a nose or spout 203 projecting over an opening 204 in the upper part of the circular wall of the eyelet pot. The lower surface of the nose of the vessel 202 is curved to fit the corresponding surface of the eyelet pot. It is apparent that with such a connection the oscillations of the eyelet pot do not interfere with the close fit of the nose 203 thereon. The larger part of the vessel 202 is open at its upper side so that at any time during the operation of the machine the operator may conveniently reach into the vessel and draw forward a portion of the eyelets therein so that they may flow downward through the nose and replenish the supply in the eyelet pot.

It is obvious that with slight changes, within the ability of the skilled mechanic, the apparatus, hereinbefore specifically described in connection with the delivery of eyelets, can readily be adapted to deliver books or other forms of fastening devices. Other changes may also be made in the form, character and relation of the parts within the scope of the invention, the characterizing features of which are set forth in the claims by the intentional use of generic terms and expressions inclusive of various modifications.
