FASTENINGJNSERTING MACHINE.

Application filed April 19, 1919. Serial No. 291,246.

his invention relates to fastening insert ing machines and, is disclosed herein as enibodied in a machine of a type in which perforating means are provided for forming perforations in the work preliminary to the insertion of the fastcnings.

In certain classes of shoes, and especially in shoes for women, it has become very common to provide wooden heels which are ordinarily finished by covering with cloth, leather, or other suitable material. In all wooden heels, however finished, it is considered desirable to provide a toplift, for exam ple of leather, which is commonly secured in the use of a plurality of line tacks or nails and a single relatively large nail driven through the top lift and into the Wooden heel substantially at the center of the tread surface. Ilei'etofore these fastenings including the large fastening have been driven by means of a well-known type of fastening inserting mechanism, speciaLprovision being made for insuring the proper setting of the large size fastening. As a result, it occasionally happens that the wooden heel is split or otherwise damaged by the driving of the large fastening and even where this does not occur the fastening. frequently set at such an angle that an edge of the head of the fastening projects above the surface of the top lift and interferes with the subsequent finishing operations and otherwise mars the appearance of the fi islied article.

Accordingly, it is an object of this invention to provide fastening inserting mechanism operative to insure the perfect setting of the relatively large fastening which is depended upon to attach the toplift securely to the wooden heel. To effect this desired result the illustrated machine is provided with means for making suitable perforations in the proper locations in toplifts and in the wooden portions of heels so that fastcuings may be driven perfectly with their head surfaces flush with'the surface of the topli'fts.

A. feature of importance consists in the provision of Work positioning means for the inserting mechanism and for the drill so constructed and arranged that the opening made by the drill is presented correctly for the insertion of the fastening. Furthermore, the work positioning means is so de signed as to gage from the plane surface of fore, that the head of the fastening will be perfectly set with same plane with toplift.

Other objects and features of the invention will be set forth in the accompanying specification and will be pointed out in the claims.

In the drawings,

Fig. 1 is a side view of an illustrative machine;

Fig. 2 is a plan view of a detached presser plate and gage member;

Fig. 3 is a front view of the machine shown iirFig. 1; and

lug. L is a view of the combined presser foot and gage member as viewed from the front of the machine.

In the illustrative machine, the fastenim inserting mechanism comprises a driver E carried by a driver bar 8 arranged to be its exposed surface in the the tread surface of the urged downwardly by the spring pressed member 10 and to be lifted after each operative stroke by a cam 12 on the front of the main shaft. Fastcnings are provided for the fastening inserting operations by means of a hopper 14 connected by a raceway 16 with a stationary nozzle 18 screwed into the lower front portion of the frame 19 and to which fastenings are delivered one by one through the operation of fastening separator mechanism not shown. The work posi tioninguneans for the fastening inserting mechanism comprises preferably a presscr foot or plate 20 arranged to slide vertically on the stationary nozzle and being further guided by a slidable connection with a pin 22 connected to and extending downwardlv from the frame of the machine and through an opening 24 in the rear end of the pres'ser plate. Plate 20 is supported by a pin and slot connection with a lever hereinafter de scribed. Mounted adjustably on the presser plate 20 is a gage member 26, preferably in the form of a member having a V-shziped notch with the wings of the V facing forwardly and designed to engage on opposite sides of the heel as the latter is. presented to the presser plate and thus to position the heel against rearward or sidewise movement. Since the fastening should be driven vertion the presser cally into the heel the under surface of the pressor plate 20 is arranged in a plane at a right angle b0 the direction of fastening insertion and the gage member 26 is adjusted plate so as to position the heel with substantially the center point of the tread surface in the line of drive. A similar work positioning means is preferably provided for the perforatin mechanism to be described later so that tile opening or perforation made by the perforating means will be provided at the location where it is desired later to drive the fastening. Preferably and as shown, the fastening inserting mechanism is controlled from the presser plate so that as the latter is moved upwardly with the work the fastening inserting mechanism is caused to operate to insert a fastening. The means for controlling the starting and stopping of the machine is of the type shown in the patent to Woodward No. 389,275, September 11 i888, and comprises preferably a lever 28 movably attached by a pin and slot connection with the presser plate 20 by a pin 30 extending laterally from a projection 31 on the plate 20 and through a slot in the frame 19 and through a slot in the lever so thatas the presser late is moved upwardly on presentation 0 the work thereto the lever 28 is caused to move about its pivot point 33 to cause the tripping of the clutch. Power is supplied to the main shaft of the machine through pulley 32 which is urged in a direction to engage a cone member (not shown) on said shaft by means of a pivoted member 34 which is pulled in the proper direction by means of a spring 36 attached to the upper end of said member 34 and to a stud 38 on the frame of the machine. The member 34 and the connected pulley 32 are normally held in clutch releasing position by means of a latch 40 adjustably pivoted at 42 and carrying a catch plate 4-1 arranged to engage a second catch plate 46 on the member 34. Latch 40 is normally held in operative position by a spring 48 as clearly shown in Fig. 1 of the drawings. In order to release latch -10 and thus permit clutch engaging movement of the pulley 32 there is provided a link member 50 pivoted to the rear end of the lever 28 and provided at its upper end with a hook 52 designed to engage a pin (not shown) on the inner side of latch 40. a spring 54 being provided for returning the hook member 52 to its pin engaging position after it has been depressed by the operation of lever 28. It will be clear that upon pressing the work against the presser plate 20 to cause upward movement thereof lever 28 will be operated and thus produce downward movement of the hook member 50, thus causing the release of the latch member 40 from its latching position shown in Fig. 1. Following the release of the latch member 34, together with the pulley 32, moves to the right under the action of spring 36 to cause the engagement of the clutch with the consequent operation of the fastening inserting mechanism through the aforementioned main shaft. As will be seen from an inspection of Fig. 1, the latch 40 is pivotally mounted on a lever 56 pivoted at its lower end at the point 33 and carrying at its u per end a roll arranged in a cam slot 58 in the cam 60 on the said main shaft, the arrangemcnt being such that the latch 40 is carried to the left toward the termination of one revolution of said shaft to cause the engagement of catch plate 44 with the catch plate 46 and the consequent movement of the pulley to clutch releasing position, the spring 48 assisting in this operation by returning the operative end of the latch 40 to its normal uppermost position. At the same time that the pulley 32 and the memher 34 move toward the left in Fig. 1, as described, a brake mechanism indicated genorally by reference character 62, and disclosed more fully in said patent to Woodward, is caused to operate to assist in the stopping of the main shaft at the termination of one revolution.

A work support is preferably provided for moving the work into contact with prcsser plate 20 and to cause the operation of the inserting mechanism, said support comprising preferably a post 64 vertically slidable in guide members, one of which is shown at 66 and provided with a trcadle mechanism (not shown) for causing movement of the post upwardly upon actuation of the trcadle. At the upper end of the post 64 there is provided a work engaging member 68 designed to conform to and suitably engage the concaved heel seat portion of the heel. As shown, this member is preferably provided with a curved and roughcnei'l surface 69 for engaging the aforementioned portion of the heel and holding the same properly while it is being pressed against the )resser plate.

ounted on a bracket 70 extending from the frame or standard 72 of the machine is a perforating mechanism which, in the illustrated embodiment of the machine. is shown to comprise a drill mechanism 74 having as its principal element a drill 76 arranged to be continuously driven from a pulley 78 connected by a belt 80 with a large pulley 82 on a counter shaft 84 mounted in the bracket 70 and arranged in turn to be driven from a pulley 86 driven by means of a belt 88 which passes around a pulley 9O fixedly attached to the power pulley 32. Normally, the drill will be running continuously during the operation of the machine. Should it be desired, however. to use the inserting mechanism for any length of time without making use of the drill mechanism the r0- 7 tary movements of the latter may be terminated lw shifting the hand lever 92 to the left in Fig. 1 of the drawings, thus permitting the spring 94 to more the clutch carrying sleeve 90 to the left, so that the friction clutch indicated at 98 is moved into clutch releasing position, pulley 86 under these conditions running idly and not cfi'ccttn movement of the pulley 82. It will he note that no work so apart, with respect to which the work would have to be positioned, s provided and that the drill mechanism is mounted stationarily in a substantially horizontal plane so that the operative can readily present the work thereto b shoving the heel upon the drill as he stunt s in front of the machine. This operation requires little efi'ort since the heel is not being moved it wardly but in a direction which requires t e minimum of effort since a slight movement forward of the hand or't-hc hand and body of the operative is sullicient to effect the proper engagement of the work with the revolving drill.

In order to facilitate the presentation of the work to the drill there is provided a work positioning means which preferahly takes the some form as that described in connection with the inserting mechanism. As illuslratcd, it comprises a plate 100 mounted on a block 10:? carried by a rod ltl-l mounted for endwisc movement in the bracket TI) and normally held yicldingly n forward position by a spring 106 located in sockets in alincment with each other in the bracket and in the block 102 as clearly disclosed in Fig. l. \Vhcn the work is pressed against the plate 100 the latter moves toward the drill which thus perforates the work, the movement of the plate to icrmit the drilling operation being limited W the engagement of an adjustable screw threaded member 108 with an abutment 110 upon the bracket member 70. The construction ofthc drill 76 with an enlarged portion at a predetermined distance from the free end of the drill and the arrangement of the work positionin' means with respect to the drill are such t not an opening of proper depth is made in the loplift and heel 111 and there is provided also an enlargement of the openlug. at the surface of thc toplil't so that the head of the insortccl fustcning will he countersunk ith its surface lltlsll with the tread surface of the hccl. in order to locate the heel so as to perforate the some at substantially the center point of the tread surface thereof there is provided a gage 112 which is preferably of the. same ty e as that described in connection with t e work positioning means for the. inserting mechanism. As illustrated. this gage is formed with a V-shaped notch and is mounted adjustably as indicated at 1H upon the block 102 which carries the presscr plate 100. Since the gage is adjustably mounted it may be readily located so that heels of various sizes may he imperly positioned to have an opening dri ed therein suhstantially centrally of the tread surface. It will be understood that the work positioning means of the drill mechanism and that used in connection with the inserting mechanism will be so ad'ustcd that the opening formed by the dril will be exactly positioned beneath the inserting mechanism for the insertion of a fastening in said opening. It should be noted, moreover. that. the work is positioned for both the drilling and the fastening inserting o crations by contact with the plane or tltltlt. surface of the heel, thus insuring that the fastrnings will be driwn perpendicular! into the work and removing the possibility of having a fastening so misplaced as to procnt an edge projecting above or beyond the tread surface where. as before stated, it would interfere with the finishing operations and be otherwise objectionable from the standpoint of the appearance of the finished work.

In operating with the machine which has justbeen der-zcrihed, the operative first engages a heel, to which a top lif t has been prcliminarily attached in any suitable way. with the presscr plate 100 in such a way that the tread surface of the heel is flatly engaged with the plate 100 and with sfdc portions of the heel in contact with the arms of the gage 112. Slight pressure in a Sillistantially horizontal direction causes the work positioning means to yield and permits the work to more upon the continuously rotating drill so that an appropriate hole is drilled in the heel. After this has been accomplished the heel is transferred to a position beneath the inserting mechanism and the trend surface is engaged with the pressnre plate 20 and the sides of the heel with the corresponding gage 26 so that the heel is positioned in the positioning means to correspond with its previous position while being subjected to the drilling operation and hence a fastening will he driven exactly into the perforation provided for that purpose. After the heel has been engaged with the positioning means below the inserting mcchauism. depression of the trcudlc causes upward movement oi the work support (iii first to engage the work and then to carry it up wardly to cause the tripping of the clutch on the main shaft and t c proper operation of the inserting mechanism.
