Specification of Letters Patent.
Patented Jan. 1, 1918.
Application filed October 9, 1916. Serial No. 124,554.
To all whom it may concern:
Be it known that 1, JAMES Bnaoo, a citizen of the United States, and a resident of St. Joseph, county of Buchanan, and'State of Missouri, have invented certain new and useful Improvements in Shoe-Nailing Machines, of which the following is a specification.
My invention relates to machines for automatically driving nails into the soles and heels of leather shoes.
One of the objects of my invention is the provision of a chute for the nails that is adapted to convey them from the usual hopper and feed them to the throat where they are operated upon by the driving element, said chute being removable so that it may be conveniently detached to remove the nails in the event they become clogged. Another object of my invention is the provision in a shoe nailing machine of an effective means for accurately guiding and controlling the drive arm of a machine where a long drive is essential. Still another object of my invention is the provision in a shoe nailing machine of a driving rod of relatively small diameter in position by a suitable removable head whereby it may be readily attached to or detached from the driving arm. A further object of my invention is to provide a nail ing machine with a nail throat that is continuous and of the same diameter, from the feeding mechanism to the driving chamber, thereby preventing clogging of the chamber and jamming the driving rod. And a still further object of my invention is the provision of a nail switch (or what is commonly known as a hopper block) that is effective from the hopper to the nail chute, and which may be automatically locked and prevented from feeding nails in the event the shoe, sole or heel has not been moved or fed to the proper position to receive a nail. Other objects of my invention are to provide a hopper block and associated mechanism that is comparatively inexpensive to manufacture so that it will not add materially to the cost of the shcenailing machine; to provide a simply constructed mechanism forafeeding nails; and to provide a device that is easy to ma nipulate.
I prefer to accomplish the divers objects that is securely held manner hereinafter fully described and as more particularly pointed out in the claims, reference being had to the accompanying drawings forming a part of this specification, wherein,--
Figure'l is a vertical side elevation of the nailing head of my improved shoe-nailing machine, looking at the side upon which the driving arm is disposed.
Fig. 2 is a fragmentary view of the upper portion of the machine shown in Fig 1, looking at the same from the opposite side.
Fig. 3. is a fragmentary plan of the top of the machine, certain portions being broken away for clearness.
Fig. 4: is a vertical sectional view through 318513 11 chute and the nailthroht or driving Fig. 5 is a vertical, section of outer end of the drive-arm, taken at a rightangle to Fig. 4. I
Fig. 6 is a detail view ofthe nail-switch" actuating device detached from themachine.
Fig. 7 is a detail elevation ofthehopperblock and nail-switch, lookingat the same from the drive-arm side of the machine and the adjoining elements removed for. the purpose of clearness.
Fig. 8 is a plan of the top block and nail switch shown in Fi 7.
Fig. 9 is a longitudinal horizonta l section taken on line 9-9, Fig. 7, looking in the direction of the arrows.
Fig. 10 in an enlarged longitudinal horizontal section taken on line 1()'-10, Fig. 8, locking inthe direction ofthe arrows;
Fig. 11 is an enlarged longitudinal 'hori- Zontal section taken on line l'1'1 1, F.ig 8, looking in the direction of the arrows."
Fig. 12 is a perspective'view of. the nail switching member detached.
Fig. 13' is a perspective view of the lock-, ing device detached from the hopper-hlockt Referring to the drawings, it will be ,ob-' served that a suitable raceway or slotted guide 10 is inclinedfrom the nail hoppers at the'top. of the standard of the machine to the hopper block thatfis adapted to receive the nails therefrom and feed them to the driving; mechanismf Secured to or adjacent the wall of the raceway is a suitable block 11 that isof the hopperprovided with a vertically disposed bearing boss 12 that is.Jboredwertically -and is dis 1;
provided with and is preferably:
the nail eing' of the depending otat di' a l i l 1 ngtch posed opposite the lower end of the raceway 10. This boss 12 provides a bearing for a suitable stem or spindle 13 having its oppd' site ends extended through said boss and the upper extended end provided with a circular disk 14, the marginal periphery of which projects beyond the boss, as shown, and is rovided with a -,depen'd=ing apron 15. This apron 15 is curved concentrically with the axis of the spindle 13 and adapted tomove' across the adjacent end of theraceway or g'ii'ide'10 and the bfo's's' is" pto'vide'dwith a cbr"e;sponding" enlargement 16 to permit of a Sunshiny snag fit asaip venfi the nails from entering the space between elements. This disk and the aproh" constitute a nail-selecting or feeding device that is adapted to shunt o1" carr the nails from the raceway to a position where they will fall by gravity into a proper feed passage 17 and thereby be transferred ted to the nailing member. The nail selcting device has a limited movement by providing a pin 18 upon the upper edge of the bearing boss that projects into an elongated, concentric notch or recess 19 termed in the disk 14, the ends of said ndph'o r' rsss b ifig adapted to serve as' stops when abutting the pin 18;
' Thelower end of the spindle 13, below its baring 'has attached thereto an operating lug 6r arm 20, adapted to be engaged and ,actuatedb. suitable mechanism to be hereiiiafteii fiil y' assented, wh'ieby the siiiie" is givii' a rcisib'ensry movement, thus transmitting to, the disk 14 an oscillatorji iiitidm; the limit whereof is determined byft'li length of the" notch or recess 19 iii said disk.

former disposed adjacent the upper surface of the disk, and the latter extending parallel thereto and below the under surface of the disk. The upper edge of the lower arm 26 is beveled or inclined, as shown in detail in Fig. 4 of the drawings so as to insure the nail gravitating and not lmnging upon the edge thereof when knocked oil the disk.
In order to prevent the disk rotating in the event the feed pipe 22 has been removed, a lock-pin 27 is provided, the vertical portion of whichreciprocates in a guide channel 27 provided in the block and the upper end whereof is looped so that one shoulder formed by said loop may be dropped into the adjacent portion of the notch or recess 19 when the nail notch is opposite the raceway. The looped end is continued upon the opposite side of the block and is carried downwardly past a stud 28 to prevent the rotation of the lock-pin and is then bent laterally beneath said stud 28 to prevent the accidental displacement or withdrawal of the lock-pin. The upper part of the guidechannel 27 is slotted through to both sides of the block so as to receive the top of the loop when it is in its lowermost or looking position. The lower end of the lock-pin extends down through channel 27 and rests upon the upper surface of a suitable block 40 that is secured in position by a screw or otherwise. The engagement of the loop of the lock-pin with the slot in the disk is permitted to take place upon the removalof the block 40 and will prevent the disk being rotated sufliciently to deliver and eject the nail and as soon as the block 40 is replaced the lock-pin 28 will be elevated out of said notch or recess and permit the disk to again be rotated. The nail ejected from the disk 14 gravitates through the nail chute 22 and is received into a suitable chamber 30 of the nail throat or sleeve 31, said chamber bein continuous and of the throughout so" as to avoid the arresting of the nails therein and the consequent jammin of the chamber. Nail chute 22 is pre erably removable and comprises a tube, the lower end being cut obliquely as shown at 41 in the drawing, and is fitted into the outer portion of the sleeve 81, while its upper end extends up into the block so that when the latter is released from its his tenings and removed, said chute may be readily Withdrawn. The throat or sleeve 31 is bored axially to receive the driver rod 32 which reoi-procates therein and engages each nail and drives it into the shoe. This drivsame diameter ing rod 32 is of relatively small diameter der 84, and which is preferably biturcat ed longitudinally bycutting a suitable keif ;a ly ..e d .lssg tudigia ly .throu'gh the of said i To ee ea nei i r asuitabl mi g d wayg and an ejector provided with two arms adapt ed toextendvabove and belowsaiddisk and iagonally of the .path of saidnotch, and means .for locking said disk against .ro-
