FASTENER-INSERTING MACHINE.

Specification of Letters Patent.

Patented May 14, 1912.

, To u/ Z Iir/Loml t may concern/r lic it known that I, STERHEN A. DoBYNE, a citizen of the United States, and residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in FastenerInserting `Machines, of which the following isa specification.

This invention relates to fastener inserting machines, and more particularly to machines adapted to operate upon shoes.

.llachines of the character referred to, have generally associated with the fastener inserting .niachines, means for feeding the wei-lt willi respect to the fastener inserting mechanism, a work support, and a gage for gaging the position where the fasteners are to be inserted in the work. The feeding means generally consist of an awl which also punt-,tures or pierces the work to form a hole for the reception of the fastener'.

It is sometimes desirable to drive a fastener or fasteners without feeding` the work, for instance when utilizing the machine to lay soles on shoes. or when building up and temporarily securing lifts on heels in repair In such cases it is also desirable to withdraw the work gage out of operative position.

Une of the objects of this invention therefore is to constriuft a machine in which the Work feeding mechanism can he thrown into andout of operation so as to render it effective and inefl'ectiv(` to t'eed the work at the pleasure of the operator.

Another object is to combine with the above mechanism a work gage which can be moved into and out of olierative position with respect to the fastener inserting mechanism.

' 'Another object to improve the Work feeding ,mechanisnn' the gage and the vfastener inserting mechanism itself as ,to details, and further objects will appear from the detaildescription taken in connection with the accompanying drawings in which:

Figure 1 is a front elevation of a fastener inserting machine showing one embodiment of this invention, Fig. 2 is a side elevation, Fig. 3 is a plan of the machine column and the gage, Fig. 4 is a'section on the line 4 4 Fig. 2, Figs. 5 and G are sections showing the block connecting the work feeding member and its actuator inoperative and inop` erative positions respectively, Figs. 7' and 8 are'details of the actuator lever, Fig. 9 1s a side elevation of a part of the mechanism showing another embodiment of this invention, and Fig. 10 is a section on the line 10-10 Fig. 9.

The invention is shown as applied to a fastener inserting machine of the loose nailer type es shown and described in m copending application Serial No. 593,330; it will be understood however that the invention may be equally well applied to other types of fastener inserting machines.r In this connection itwill be understood that the term fastener inserting machine is not toY be limited to that type in which the fastener is only utilized to fasten parts together, but is intended to cover also slugging machines, that is, machines in which nails are driven for wear increasing purposes.

Referring to the accompanying drawings, A' designates the machine head or frame and B the machine column upon which it is mounted. The head supports a main driving shaft which is provided with cams and pulleys` to operate the different mechanisms in a manner hereinafter described. A driver bar 16 having an attached driver 17 is mounted to reciprocate in bearings on the machine head. This driver bar is driven down by means of a spring 18, and raised against the tension of the spring by means of a cam 19 on the shaft 15 engaging a cam roll on the driver bar. A raceway 20 slides in guides in a loader C, therotary element of which is driven from the main shaft by a belt and pulley as shown in th'e drawings. The lower end of the raceway has rigidly secured thereto a nail block or throat 21, which is provided with adriver passage for the driver, and the nail block and .raceway are pivoted to the lower end of a link 22 which is mounted for swinging movement on .a pivot 23 in the machine head. A spring pressed plunger 24 operates to lmpve the link and the attached nail block and racewa. in one direction, and a' stop 25 on the mac inehead engaging a slot in the link limitsthis movement. A lever 26 provided at one end with a roll engaged by the cam 19- operates through the plunger 24 to positively return the parts to initial position.l A work support or pre'sserfoot 27 is secured-to the'ma'- chine head, and forms a support against which *the Workcan be held during the operation ofthe machine, either by hand or by beingsupported on a horn or other work support "28," The fasteners are fed from the raoeway to the throat or driver passagebyv means a separator or picker 29 operated hy means of 'a lever flfrom the cam 3l on the mainshal't. i

The support or presserfoot 2 is provided with a sint in width work the tip of the nai block andthe awt 32. This awlV is mounted upon an a'wl carrier 33, which is provided with a. hollow cylindrical shank 34 slidir'ig; in a tubular guidewzty I o'n the rn: Jhinc head and is pressed outwardly h v means vot' a spring 36. An arm 37ml the yawl carrier has a. connection with an actuating -lever 38 which has a. roll engaging a cam groove on the cam 3l. This' mechanism impart-a a piercing movement to the awl. 'lhe feed 4 ing move-ment is imparted -to the aivl by means of an actuating lever 39 the lower' end of which bears against the awl carrienand' the upper end. pf which is provided with a Cain roll engaginga cam surface on.. the cam' 31.

. The awl actuating n-iechanisin operates to'depressy the avvl so as to pierce the Work andi then imparts a feeding move-ment thereto. This feeding movement takes place. while the driver is in raised position, anddu'ring this feeding,movement the awl carrier will eng-age a shoulder Bton thev nail block land move,the nail block together provided 'with the raceway to the left.l After'the feeding movement has been completed and when the. yawl is returned or 'retracted by the icam and the 'spring 36, the yieldingly and'positively operated plunger 24 will op-f crate to move'the nailA block and, raceway back over the holemade by the awl so as to position a fastener.' directly above said hole,'which fasteneris then driven. r[he lever B9 is provided with an adjusting screw 4Q which is provided with ajlti'iurlcd head 41 andl has a spring thereon., and this Screw bears against a stationary StopAO on the machine head. B v means of this. construction the feeding movement' of the avt/'l can he adjusted. The arm 3 7 on the a wl carrier is provided with a pin or shaft 4?, which receives a block 14. This block slides in the Shaft and arranged to be moved into and ont of engagement with a fork 49 on the lever 38. rlhehlocli el is provided with a. knurled head i5 and a rounded' Springr pressed pin i6 which engages longitudinal and circumferential grooves t? and 48 on the shaft. A stop 48@ prevents the block from being pulled entirely ott the shaft.

The lower vend of the lever 3U is provided with fixed and movable, lags 5l and 52, the lng 52 being scoured to a shaft 53 so as to.. move therewith. and the shaft 53 'being with a knurled head 54 and a Spring 55'. The lug 52 is provided with a ypin or lng 56 arranged to engage either of two recesses 57 formed in the lever 39.' lThe lug 52 is' arranged 'to engage-anadp-xstable screw 5S) in the awl carrier-and both of the, lugs 5lj and 52 are provided with holes or recesses so that the screw 59 maybe manipu- 'lated 'oy .a screw' driver for the purpose of alining' the' awl with respect to,the driver 'for different -feedswithont necessitating the dismantling lof the. lever 39'.

. A workgage (35 is provided as usual with a gear and rat-.k so as to yhe capable 4of adjustment. handle (3G on the gage carrier (37 is irovided with awlfrear Ilich 'engages the rack-on thel gage'. The `faire carrier is mounted ilaterallir or on one side of the 'column -or post ,l in split bracket (i8 which is provided Wit-h a. screw so as to frictionally clamp the carrier in position'.v The Vcarrier is providedI with astop 69 cooperating with a stop [70 on the cohimn', and it will be noted that these lstops 'arev in line' witlilhe gage, face so that when the gage is in operative,- position any 'pressure' brought against it will tendrather to seat than unseat it. The gage carnbe swung intoan'd out-of operative position 'nnderneathlthe fastener inserting mechanism.

`Vt'hen, the' parts are in the positions shown in the drawings'the actuating mechanisms forft-heawl o r work feeding lmemberhave an operative'connectionV therewith so 'that the awl is effective.. for 'feeding the work. The awl can b e'v thrown ont: of: 'operation and its feeding actio'n 'interrpted'in two wayslirst, 'by'interrupting its` piercing aetion, and second, byf interropting its feedf 'ing action, 'or thesetwo gmethods may be used in conjunction to arrestl the 4actions of theawl, altogether.

In accordance witlrthefrst method the piercing action -of the aw] Vis linterrupted by moving lthe block dlfrom 'full iline to dotted line 'position Fig. 1. lVhen the block@ is so withdrawn therc is' siiliioient play or lost motion between the members 3T and so that lthe movement of the actuatorv lever will have practically no effect vuponv (he awl" carrier. ln order that. the awl may be withdrawn from the work and placed in retracted pmition. a spring 5) having, one end secured tothe arm 37 and tl1e, otl1er' endl to the machine head "is arrangedto swingJ the awtcarricr and place the awl in retracted or withdrawn position ont. of the work For this purpose the block is eccentric as showmso that the shaft 43 and the awl carrier can have a movement snfiicient to withdraw the awl completely from the work,y even'though the lever 38 is ati the the awl will now be raised so that it will not pass through the presser foot. lt is therefore no-t necessary that the awl carrier.

be completely disconnected from its actuator-.provided the awl will not in its lowest position pass through the presser foot. The pin and groove connection between the block 44 and the shaft 43 is provided so that the block will be retained in correct position when withdrawn and' thus can be moved into operative and inoperative positions, even while the machine is running. vThe groove 48 is slightly deeper than the groove 47 so that the block will be yieldinglylatched in operative position. This block is, of course, long' enough-to permit the necessary feeding movement of the awl and its carrier when the block is latched in operative position, y

`In accordance with the second method the feeding action or movement of the awl can be interrupted by swinging the lug 52 out of alinement with the screw 59 and the awl carrier, the lug being held in the second or inoperative position by the engagement of the pin 5,6 with the other of the recesses 57. When the lug is in this last named position there will be `no feeding engagement between the lever 39 and the awl carrier so that no feeding movement will be imparted to the awl, the awl carrier remaining in retracted position in which it is placed by the spring 36. In this case the fork 49 forms a stop for limiting' the retracted movement of the. awl. When the lug is thrown out of the path of the screw 59, -the spring 36 will move the awl carrier until the head of arm 37 abuts against and is stopped by the fork 49. The gap' between 51 and'52 is sutlicient so that 51 will not engage or operate the awl carrier. Any other suitable stop vmay of course be provided to limit the retracted movement of the awl and its carrier. In this case the piercing movement of the awl is not interrupted but the feeding movement is. This may, of course, be objectionable in certain classes of work where it is not desirable to mar-the work.

It will be understood that the separate means for rendering the work feeding mechanism inoperative or ineffective may be used.

separately or in conjunction, EachY has its advantages and disadvantages, thus the first method keeps the nail block and raceway in motion while the second does not. The former is however advantageous where the movement of the raceway is utilized to prevent blogging of the nails as in this specific e bodiment.

igs. 9 and 10 show a construction in which the lever 39 has a plain engaging portion instead of beingprovided with a movable lug 52. In this construction the feeding action is interrupted by the shifting block 44 as in the construction shown in the other figures, so as to merely interrupt the piercing action of the awl, leaving its movement inthe line ofv feed unimpalred. The end of the lever 39 is also provided with a hole or recess 58a for a tool. Similarly the connection between lever 38 and the awl carrier may be ya simple connection as in my prior application referred to. In this case the feeding operation can be interrupted by shifting the lug 52so as to interrupt the feeding movement and action of the awl leaving its piercing action unimpaired.

It is desirable, in some classes of work when the awl isthrownout of operation, 'that the gage be also thrown out of the way for instance` when the machine is used for laying soles or for temporarily securing heel lifts in position in repair work. In the sole laying operation, the sole is laid on the shoe or last and a number of fasteners driven along the center of the sole or in the channels and heel seat. This, of course, requires a machine which has no gage, and an awl feed is also not desirable in this case since it will tend to shift the loosely laid sole out of position. The same'is true of heel repair work. In accordance with this invention the machine can be rapidly converted into a sole laying 'or lift attaching machine, and can also be converted back into a sole attaching or a slugging machine at the pleasure of the operator.

It will thus be' seen thatthis invention provides means whereby the work feeding mechanism can be rendered effective and ineffective at the pleasure. of the operator. This is accomplished by making and breaking the connection between the work feeding memberand its actuatingmechanism, or

by raising the member out of engagement with the work and retaining it out of en-y gagement While the fastener inserting mechanism remains uninterrupted to insert fasteners.- The awl or Work feeding member, can also be adjusted to vary its feedingT stroke and its position with respect to the fastener inserting mechanism.

The awl and the nail block' or throat are moved transversely with respect to the driver through the actuating lever 39. The awl and nail block are however returned through independent means. the awl through the spring 36 and the nail block through the yielding and positively actuated plunger 24. The nail block is positioned in alinement with the driver by means of the stop 25 on the machine head or frame, and the awl carrier is arrested by the engagement of the screw or stop 40 thereon with the stop 40a on the machine head or frame. The adjustment of the screw 40 enables the feed of the awl to be adjusted. The nail block and awl carrier are therefore arrested by independent stops. The screw 59 is adapted to accurately aline the awl with the driver as is herir-'srt it justine-nt of the screw 40 for the purpose of varying the .fi-cil will not disturb the alinemcnt ot the nail bloei; with the driver, and thc adiustment of the screw 59 for the purpose of aiming' the a wl with the driver will not disturb the feed of the awl nor the position of the nail block. The positioning means for thc nail block and the adjustments for the a\vl are therefore absolutely independent so that the adjustment of one will not disturb the other.

it, is obvious. tuat various changes may be made in tht details of construction Without departing from this invention, and it is therefore to be umlcrstotal that this invention is, not to be limited to the specific coni the .-aitl being movable into and out of operative position.
