' Figure 17 is an enlarged end elevation of Fig. 16.

Figure 18 is an enlarged horizontal section .of the staple taken on the line XVIII- Referring tothe drawings 1 designates a base member having a pair of upwardly extending standards 2, said base member being secured to a supporting stand 3 by a bolt 4. Formed on each of the standards 2 adjacent their upper ends is aY bearing '5,

`said bearings being for the support of a horizontally arranged` power shaft 6, and mounted on one end of said shaft is a driven pulley 7 which may be. driven from a motor or other source of power while the opposite end of said shaft is adapted to support a turning handle as shown in dotted lines in Fi .1and3.A

ecured tov said shaft 6 between the bear ings 5 is a cam wheel 9, and formed in one of the side faces of said cam wheel is a triangular shaped cam-way 10, having cam roller dwells 11, the intermediate portion of said cam-way between the dwells forming a cam 12 vhaving actuating portions 13.

vAdapted to traverse the cam-way 10 is a. roller 14 which is mounted at Vone end of a rockernarm l5, said rocker arm being intermediately pivoted at 16 betweema pair-.of bearings 17, one of which is formed inte al with the extending portion 18 of each of the "standards 2. The opposite end of said rock- Figure 13 is a front elevation taken on the line XIII-XIII of Fig. 1.

cured toI the extending ends of said supports 20 by screws 21 is a depending driver bar 22 which is preferably constructed of spring steel so as to be flexible.

Integrally formed with each of the extending portions 18 of the standards 2 is an upwardly extending side wall 23, and mounted between said side walls is a staple receiving hopper 24.` Secured to the front end of the hopper 24 is a front plate 25, which forms part of the forwardly extending portion 26, the upper surface of said portion 26 being inclined, forming an inclined trackway 27, said track-way 27 having a rearwardly extending portlon 28 which extends into the hopper 24.

Carried by the front end of the portion 26 is a guide block 29 having a staple receiving guide-way 30, said guide-way being in communication with the lower and frontend of the track-way 27, and having a cover plate 31 for closing said guide-way. f lThe lower end o the hammer 22 is reciprocally mounted in the guide-way 30, and secured to the cover plate 31 is a leaf spring 32 having an inwardly extending portion 33 which extends through an opening 34 formed in said cover plate, said inwardly extending portion being below the hammer 22 when` the hammer is in elevated position, said portion 33 of said leaf spring also being below the inclined surface of the track 27, (see Fig. 10).

Formed on each side of the portion 26, adjacent its lower end is a horizontal guiding surface 35, and slidably mounted on each of said guiding surfaces is a gripping or holding member 36, the forward ends of said members, as designated at 37, adapte'd to enter the guideway 30 of the guide block '29. These members 36 are tied together by the rivets 38, and there,being an opening 39 formed in the portion 26 for the Vtravel of said rivets and their respective spacer members during the reciprocation of the gripping members 36.

Formed in one of the members 36 is a socket 40, and engaged in sa'id socket is a rounded end 41 of a bell .crank lever 42 which is pivoted atl 43 to the portion 26, the opposite end of said lever 42 being bifurcated as designated at 44, said bifurcated end of said lever being engaged by a pin 45. which is carried by one of the Vhammer supports20. Mounted on one side of the extending por tion 26 is a spring actuated arresting lever 46, said lever being mounted on aA transversely arranged bolt 47 which passes through the portion 26, and mounted on said bolt at the opposite side of said Aportion 26 is another spring actuated arresting lever 48. Each of these arresting levers 46 and 48 have an angularly bent portion 49 and 50 respectively. j

Co-operable with the arresting lever-'46 is an ` actuating finger 5,1 which is carried by the rocker arm 15, and co-operable with the arresting lever 48 is an abutting portion 52 which' is carried by one of the hammer supporting portions 20 of the rocker arm 15 (see gecuredf'to the front plate 25 is an inclined guiding plate 53 which holds the staples in sliding relation to the trackway 27, and prevents them from jumping off as they leave the hopper 24. Passing through the hopper 24 is a transversely arranged shaft 54, and secured to said shaft is a staple lifting member 55, said member being comprised of a hub 56 to which a pair of square formed plates 57 are secured, and formed in each of said plates adjacent the corners thereof, and in oppositely disposed positions, l

are staple gripping notches 58.

The extending portion 28 of the trackway 27 extends between the plates 57 of the staple lifting member-55, as shown more clearly in Fig. 7, and there being a rearwardly inclined surface 59 formed on said portion 28, which at one end is within the arc of the circle travelled by the notches 58, whereas the upper end of said inclined portion 59 is above the arc of the circle travelled by said notches. One end .of the shaft 54 extends through the hopper 24, and mounted 0n said extending end of said shaft is a grooved pulley 60 which has a crossed endlessl belt 61 mounted thereover, said belt at its opposite end being mounted over a grooved pulley 62 which is secured to the power shaft 6. 'Extending upwardly `from the rear `of the base 1 is a bracket '63, and pivoted tosaid bracket bythe bolt 64v is a bearing65, said bearing being for the support of one end of a feed shaft 6.6. .Mounted on sadshaft is a'ratchet wheel 67 which carries a plurality of spring actuated ratchet teeth 68.

Mounted on the hub 69 ofthe ratchet wheel isa lever 70, having a slot 71 formed therein,

roller carrying end is one end of a coil spring 76, having its opposite end secured at 77 to the rear wall of the hopper 24. The

shaft 6.6 extends approximately horizontal beneath the rocker arm 15, the forward end of said shafty being journaled in a bearing 78 which is pivotally supported at 79 to a movable support 80, which is mounted in a casing 81, said casing being secured to the forward end of the base 1.

Centrally and transversely arranged in the casing 81 is a bolt 82, and turnably mounted on said bolt is a shifting plate 83, said plate having a roove 84 formed therein, which is arranged eccentric with the bolt 82, said groove bein for the reception of one end of a pin 85 w ich is carried by the movable surport 80.

ecured to the shaft 66 adjacent the bearing 68 is a knurled roller 86 having an annu ar groove 87, said groove being in vertical alinement beneath the lower end of the guideway 30 ofthe guide-block 29.

Referring to Figs. 16 to 20, it is preferable to have the staples used in this improved stapling machine bevelled as designated at 88 at their puncturing ends, said bevelling to be done on the outer sides of the legs 89 of the staple, and diagonally of the center line A, shown in Fig. 18, so that when the staple is driven into the material, the legs 89 thereof will defiectfrom' a right line, and be driven angularly .and inwardly towards each other, and yet will pass one another without touching, as shown in Figs. 19 and 20, thereby securely sewing two or more pieces of material together.

In the operation of this improved stapling machine, a quantity of staples on the order of the one shown in Fig. 16, in which the legs thereof parallel one another are dumped into the hopper 24, and power is given to the sha-ft 6, either bythe cran-k handle 8 or motor power from the pulley 7. In the meantime a shoe to be soled is engaged and held with the sole lowermost and the extending edge of the welt and sole thereof is inserted between the guide block 29 andl roller 86, and the handle 90, which is secured to the shifting plate 83 is moved upwardly, thereby clamping the sole between the roller 86 and the guide block 29.

During the rotation of the shaft 6, the staple lifting member 55 upon being revolved in the direction of the arrow shown in Fig. 7, will force one or more staples into each of the notches 58 thereof, and carry the staples upwardly until the staples are forced from their respective notches on to the inclined surface'59 of the trackway extension 28, and eventually on to the downwardly inclined trackway 27. y s

During the travel of. staples down the trackway 27, and in straddling position thereof, the first staple in o rder will be engaged by the angular portion 50 ofthe arresting lever 48, and in the timing operation or actuation of the rocker arm 15 the lever 48 `is moved from engagementwith the track- `way, thereby allowing the first staple in order to travel farther down the trackway where it is arrested by the track engaging Aportion 49 of the arresting lever 46. The

moved by the rocker arm 15 until it engages and moves the arresting lever 46 from engagement with the trackway 27, thereby allowing the first staple to slide down to the end of the trackway and rest against the driver bar 22 as the lower portion of said hammer is still below the inclined staple passage-way 91 of the guide block 29.

The staple resting against the driver bar is then in position to immediately drop into the guideway 30 as soon as the driver bar has travelled above the passageway 91, the upward and downward reciprocation of said driver bar being caused by the rocking movement of the rocker arm 15 which is actuated by the camway 10 of the cam wheel 9.

As shown in Fig. 1, the roller carrying end of the rocker arm 15 has been forced downwardly, thereby elevating the opposite end of said rocker arm, in which the lower or staple engaging end of the driver bar 22 will be moved above the passagewa 91 of the guide block 29, thereby allowing the staple to drop into the guideway 30 where it will be engaged by the extending end 33 of the leaf spring 32, and simultaneous therewith, the gripping members 36 will engage against the legs 89 of the staple. thereby holding it against the plate 31, (see Fig. 10).

The driver bar 22 is then moved downwardly and since the staple is now in the path of travel of the driver bar in the guideway 30, the staple will be forced from its spring held position down between the forward ends of the gripping members 36, and as the legs of the staples enter the leather of the shoe sole, the staple legs being guided thereto and held in a straight position by the gripping members 36, said gripping members are then moved rearwardly and out of the way of the descending driver bar by the actuation of the bell crank 42, the staple engaging end of the driverbar traversing the gu1deway30 to the bottom thereof, therebyforcing the staple into the sole leather of the shoe.

1n the descending or driving operation of the driver bar 22, the arresting lever 46 is again actuated by the finger 51, thereby allowing another staple to vcomplete its travel down the trackway 27, where it will engage a ainst and be held by the hammer until the river bar is elevated by the return movement of the rocker arm 15, which return movement of the rocker arm will cause the gage the arresting lever 48 so as to allow the next staple bearing therea-gainst to ride against the arresting lever 46 so that it will be ready for a succeeding discharging operation after each staple driving operation of the driver bar 22. As the driver baris moved upwardly, the depending portions 74 and pin 75 carried thereby will force the lever 70 downwardly, thereby causing the vabutting portion 52 carried thereby to endog 72 carried by said lever 70 to bear on an adjacent tooth 68 of the ratchet Wheel 67, thereby actuating the ratchet Wheel 67 and incidentally rotating the feed roller 87, and inasmuch as the surface of said roller is in engagement with the underside of the shoe sole, the shoe sole will be moved to a position ready to receive the next staple.

From the aforesaid operation it is to be noted that the movement of the rocker arm 15 actuates all of the parts relating to the discharge of the staples from the trackvvay 27, the guiding and driving of the staples through the guide block and the feeding over of the shoe sole, thereby providing for a simple and inexpensive construction of a stapling or nailing machine.

After a shoe has been soled with this improved macliine, the staples contained therein will be clinched as before described, and as shown in Figs. 19 and 20, thereby providing a secure fastening means which Will be susceptible to any desired amount of flexibility as regards good Wearing qualities of a shoe sole which is constructed or repaired in the manner described, as the inclininfr clincliing positions of tlie staple legs Wil afford and allow the natural suppleness of a shoe sole as against the ordinary type of nailed sole, in which the nails are vertically arranged in the sole. Furthermore, the points of the staple legs are' driven downward in a shoe sole as against the upward driving of shoe nails.
