LASTING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 559,130, dated April 28, 1896.
Application filed December 18,1395. Serial No. 572,576. (N model.)
To aZZ whom it may concern.-
Be it known that I, LOUIS GODDU, of Winchest-er, in the county of Middlesex, in the State of Massachusetts, have invented an Improvement in Lasting Apparatus, of which nail-driving mechanism being automatically controlled or governed as to its operation by bodily movement of the nail-driving mechanism. Means are also provided whereby when the nail-drivin g mechanism is in operative position manually-operated means effect a connection between the driver-actuating devices of the nailing mechanism and the powertransmitting mechanism.
In the apparatus herein shown when a nail or tack has been driven the power'transmitting mechanism and the driver actuating means are automatically disconn ected, so that when another tack or nail is to be driven or inserted the driver-actuating means must be 5 manually connected or brought into operativc engagement with the power-transmittin g mechanism.
Other features of my invention will hereinafter appear and be fully described in the specification, and particularly pointed out in the claims.
Figure 1, in side elevation, represents the upper portion of a lasting apparatus embodyin g my invention, the bodily movable nailing 5 mechanism being shown as ready for use. Fig. 2 is aside elevation of the work-support to be described,partially broken out, and with the arm to which the upright standard is secured. Fig. 3 is an enlarged sectional view of the joint connecting the work-support and its standard. Fig. 4 is a greatly-enlarged sideelevation of the nailing mechanism shown in Fig. 1 detached and partially broken out. Fig. 5 is a sectional View on the line 09 00, Fig. 4, of the mechanism to the right 5 5 thereof. Fig. 6 is a front elevation, partially broken out, of the nail-driver and its cooperating devices.

Fig. 13isalongitudinal 6 5 sectional view taken on the driver-actuating shaft and through the clutch devices. Figs. 13 and 13 are end and perspective views of a part of the clutch. Fig. 14 is an enlarged side elevation of the guideway detached. Fig. 15 is an opposite view of the nose or throat thereof. Fig. 16 is a top or plan View of the guideway. Fig. 17 is a transverse section thereof on the line 09 a Fig. 16, and Fig. 18 a similar section on the line x 564. Fig. 19 is an end view of the hopper with the cap or cover removed. Fig. 20 is art-enlarged view, partly in section, of the clutch for the powertransmitting mechanism; and Fig. 2i
is a sectional view on the line 3 11, Fig. 20, looking to the left.
Referring to Figs. 1 and 2, the lasting apparatus, which consists, essentially, of a support for the boot or shoe to be lasted, a bodilymovable nailing mechanism, and mechanism to transmit power to said nailing mechanism, is shown as mounted upon a suitable column A, said column having bolted or otherwise secured thereto an u pwardly-extended and rearwardly-bent arm or standard A, to the upper end of which is pivotally mounted a swinging support A pivoted on a shaft A (Shown more clearly in Figs. 20 and 21.)
The column A is made hollow and is split at its upper end and internally threaded to 5 receive a hollow post or standard a, socketed at its upper end, as at a, to receive therein a ball-like portion a of the last support a, having a suitable. heel-pin 2 and adjustable toe-rest a (see Fig. 2) to support the last L upon which the boot or shoe to be lasted is placed, it being understood that the operator in lasting will with a pair of suitable handpincers pull the edges of the upper over the inner sole, and by means of the nailing mechanism to he described will secure the overturned edge of the upper in place upon the inner sole by tacks or other similar fastenings.
Between the ball a and its socket a, which together form a ball or swivel joint, is preferably interposed a concavo-convex Cushion or washer w, of leather, rawhide, or other suitable material, the said ball being cut away interiorly to form a socket a in which rest-s the ball-like upper end a, of a clamping-rod a", extended through a-suitable hole in the cushion w in the standard a, said rod a being connected at its lower end by a rigid link a to an eccentric a", (see dotted lines, Fig. 2,) fast on the fulcrum a of the counterbalanced treadle T.
Normally the counterpoise W will tend to elevate the clamping-rod a so that the lastsupport a may be moved in various directions on the socketed top of the post or standard a, the lower part of the ball a being cut away conically at a Fig. 3, to allow free play of the ball in its socket and yet permit it to be clamped in any position by depression of the treadle T by the foot, the treadle operating the eccentric.
The split upper end of the column A is tightly clamped upon the threaded standard a by means of a suitable bolt 3 when the latter has been adjusted to the desired vertical height.
The bodily-movable nailing mechanism designated at N as a hole, Fig. 1, is suspended by a shaft 1) from the swinging arm A said shaft being connected by a universal joint I) at its upper end to a short shaft 5 rotatable in bearings 17 on the outer end of the arm A said sheft shafthaving fast thereon a preferably grooved pulley 19 intermediate the *bearings and connected by a flexible band or belt If to a larger driving-pulley 19.
Referring to Fig. 20, the pulley b is shown as provided with an elongated huh I)", mounted to rotate loosely on the shaft A and forming the driven member of the clutch, the other member being shown as a pulley b adapted to be continuously rotated bya belt from any suitable source of power, the hub of the pulley rotating on the hub b of the clutch member I), a suitable friction-washer 10 being interposed between the adjacent faces of the clutch members.
A spring 8, surrounding the hub of the pulley o bears against and normally tends to separate the cooperating member Z) therefrom to release the clutch, the pulley 5 as shown in Fig. 20, being held from longitudinal movement on the shaft A by a flange A of the swinging arm A pivotally mounted on the shaft A beyond the pulley and held in place by a suitable nut 6, a washer 10 being interposed between the pulley and the flange or arm A.
WVhile the member b of the clutch is continuously rotated, the cooperating member Z) is normally at rest, and I have provided means for automatically throwing the clutch into or out of engagement by the bodily movements of the nailing mechanism from its position of rest into its operative position, (shown in Fig. 1,) and such operation of the clutch is controlled in this embodiment of my invention by the movement of the swinging arm A about its pivot or fulcrum A The arm A is notched at c, Fig. 1, to straddle a projection c on the outer face of the upright A to limit the movement of the arm A in one or the other direction, the arm being shown in Figs. 1, 20, and 21 as at the upper limit of its vertical movement with the clutch in engagement to cause rotation of the depending shaft 1) by or through the band I).
A counterbalancing-spring S surrounds a rod 0 interposed between a lug c on the inner side of the arm A and an adjustable bushing c on the upright A, said rod having a nut 7 on its lower end below the bushing and a pin 8 (see Fig. 21) on its upper end to retain the upper end of the spring S in place, depression of the swinging arm A compressing the spring, the latter tending to maintain it in a state of substantially stable equilibrium.
On the inner face of the upright A is secured a cam 0 adapted to cooperate with a sleeve 0 longitudinally and rotatably movable on the shaft A the cam c engaging the inclined face 0 of the sleeve 0 so that when the arm A is raised a spring 3 Fig. 21, partially inclosed in a housing 0 of the sleeve and bearing at its other end against a lug a on the upright A, will turn the said sleeve in the direction of the arrow 10, Fig. 21. This rotation of the sleeve, by reason of its wedgeface 0 and the cooperating fixed wedge-face 0 moves the sleeve bodily to the right (Fig. 20) to press the movable clutch member I) into engagement with the continuously-rotating member 19 to immediately throw the clutch into operation and thereby rotate the shaft 1), the member I) and sleeve being separated by a washer r0 \Vhen the operator desires to stop the powertransmitt-ing mechanism, he lowers the nailing mechanism N, drawing down the arm A from the position shown in Fig. 1, apin 12 on said arm engaging a pin or projection 14 on the sleeve 0 and turning it thereby in the direction. opposite to the arrow 10, Fig. 21, compressing the spring 3 but allowing the weaker spring 3 then to expand to separate the two clutch members and thus stop the power-transmitting mechanism.
The two springs s and 8 act substantially at right angles to each other, the spring 8 being the stronger of the two, as it has to turn the sleeve against the friction of the wedgefaces 0 and c and the pressure of the spring sin throwing the clutch into operation. The
hook A (see Fig. 1) on the upright A, a very slight movement of the operators hand being sufficient to remove the shaft from the hook orplace it in engagement therewith.
While in the apparatus herein shown the arm A which sustains the nailing mechanism and power-transmitting mechanism, is swung upwardly to start said power-transmitting mechanism and swung downwardly to automatically stop it, it will be obvious that a mere reversal of these movem ents would comewithin the scope of my invention.
Referring now more particularly to Figs. 4 to 13*, inclusive, the nailing mechanism comprises a frame D, of suitable shape to provide bearings for the operative parts, having rigidly attached thereto a handpiece or handle D, which is grasped by the operator to direct the bodily movement of the nailing mechanism, the frame D having an upright tubular extension D closed by a cap D in which extension reciprocates the head cl of the driver-bar d a com ressing-s rin S of sufficient power being placed in the tubular extension D between its cap and the head 01 of the driver, the latter being cushioned at (ZX,
as is usual in spring-depressed drivers.
A block d secured by a set-screw 15 to the driver-bar d, )lays in a vertically-slotted portion of the frame D and is adapted to be engaged bya cam projection d on the cam-block D the latter being shown best in Figs. 7 and 8, the rotation of the said block in the direction of the arrow 25, Fig. 9, gradually lifting the driver and suddenly releasing it when at its highest position to be depressed by the expansion of the spring S the driver-bar (1 having secured to its lower end the driver (I vertically movable in the nose d of the nailing mechanism, said nose having on its under side a sharpened lip or prong d to enter the material of the upper at the rear of the nailpassage to assist in holding the upper in place while the tack or nail is being driven therein.
The cam-block D is screwed onto the reduced end 6 of the shaft 6, having a slight longitudinal movement, for a purpose to be described, the cam-block rotating in a bearing D, forming a part of the frame, and the outer end of the shaft 6 in a bearing D, also forming a part of the frame D.
The reduced portion 6 of the shaft is also screwed into the hub f of a clutch member f to be rigidly secured thereto, the inner face of said member f having radial engaging projections or teeth f Fig. 4, to be engaged by similarprojections or teeth g on theinner face of the coupling clutch member g, loosely mounted on the shaft 6, when the two members are pressed toward each other.
A spring 8 interposed between the reduced portion of the hub f of the clutch member f and the annular flange or hub g of the member g, normally tends to separate the clutch members by forcing member f with its attached shaft and cam-block to the left, Fig. 13.
The clutch member g has a toothed periphery g in mesh with a gear h on a shaft h, mounted in bearings D, said shaft having at its outer end a pinion h in mesh with a beveled gear it, formed on the base of the hopper H, (see Figs. 1 and 4,) to be hereinafter described. a
The clutch member 9 has secured to'or forming a part of it a spiral gear g in mesh with a worm g fast on a shaft 9 (see dotted lines, Fig. 5,) vertically mounted to rotate in vertical bearings D and connected at its upper end by a universal joint 9 to the lower end of the depending shaft 71, forming a part of the power-transmitting mechanism, so that whenever the power-transmittin g mechanism is in operation the loose member 9! of the clutch members f 9 will be continuously rotated, and the hopper H, through the intermediate gearing described, will also be rotated. The spiral gear 9 and worm 9 give a very steady and even rotative movement with little or no lost motion.
The nailing mechanism is constructed to drive a tack or other fastening at each depression of the driver, and the operation of the driver is controlled by manually-operated means to cause engagement of the clutch members f 9, such engagement when the power-transmitting mechanism is in motion causing one complete revolution of the driveractuating shaft 6 to lift and release the driver, the driver-depressing spring S forcing the driver down quickly as soon as the cam-lug d releases the block 01 and the driver-bar.
Referring to Figs. 13 and 13 an annularly flanged collar is loosely mounted on the hub of the clutch member f, the flanged face of said collar having thereon, preferably, two oppositely-inclined cam-lugs k, wedge -like in shape, to normally enter correspondinglyshaped recesses 70 in the adjacent face of the bearing D a washer 10 being interposed between the other end of the collar and the clutch member, one end of a spring .9 enter ing a suitable recess in the collar 70, the other end of the spring resting against a ing 25 on the main frame D, the said spring tending normally to maintain the collar in such position that the lugs 7t thereon will enter the recesses 7% thereof.
The collar has a notch lei-(see Fig. 13,) adapted to beentered at times by one tooth, as m, of a compound pawl m,pi.votally mounted ina pawl-carrier, (shown best in Figs. 4 and 5,) as a lever m fulcrumed at m in the frame and normally pressed outwardly by a spring 3, (see Fig. 5,) the compound pawl shown as normally elevated by a bent spring .9 Fig. 5.
hen the operator desires to actuate the driver, he presses with his forefinger the tail m of the pawl-carrier m to bring the tooth m of the compound pawl into engagement with notch of the collar 70 to turn it in the direction of the arrow 30, Fig. 13 on the hub of the clutch member f, such rotative movement by the cam-lugs 7c acting on the illclined faces of their sockets or seats 7%, moving the collar and thereby the clutch member f on its shaft 6 to the right, Fig. 13, to bring the adjacent faces of the clutch members f 9 into engagement, and immediately the rotation of the latter member is transmitted to the member f, the shaft 6, and camblock D to rotate them in unison.
The pawl is retained in engagement with collar k until "the lifting-cam 61 engages the block d on the driver-bar and begins to compress the driver-spring S the resistance of such spring after the pawl has been released, as will be described, keeping the clutch members in engagement until the shaft 6 has been rotated sufficiently to release the driver-block and permit the d river-sprin g to act, the starting and stopping positions of said liftingcam (1 being shown in Figs. 8 and 9, so that when a tack or nail has been driven the driving mechanism is automatically stopped, the spring 3 having sufficient power to separate the clutch members when relieved of the op posing tension of the driverspring S.
The lifting-cam D has a peripheral groove (Z therein of a width corresponding to the width of the tooth m of the pawl m, a projection (Z in. said groove acting upon said tooth in the rotation of the lifting-cam to depress the pawl or lug in order to thereby withdraw the pawl-tooth m from the notch k of the collar 7c, the latter being immediately drawn back or rotated in a retrograde direction by its spring 8 into normal or inoperative position, (shown in Fig. 13,) leaving the separating-spring .9 free to act when the driver has been depressed by its spring.
It will thus be seen that while the powertransmitting mechanism may be continuously rotating the driver will be actuated once only for each movement of the manually-op erated clutch-controlling means, and the operator holding the nailing mechanism in one hand can thereby move it over the bottom of the boot or shoe held on the last, as described, to insert a tack or nail from time to time as with the other hand he draws the upper over the inner sole.
A guard 50, clamped upon the extension D of the frame of the nailingmechanism, loosely surrounds the lower end of the depending shaft 1) and prevents the nailing mechanism from entirely swinging about the joint when the operator releases the handle D.
The frame D has at its lower portion adjacent the handle D a seat D for a guideway 07, (shown separately in Figs. 14 and 16,) the said guideway being cylindrical at its lower portion and secured in the inclined seat D by suitable screws the guidewa* bein 7 k b grooved longitudinally at a to form a passage-way for the bodies of the tacks or nails, the heads of the latter resting upon the top of the guideway and passing under a clearer n covering the lower portion of the groove, and longitudinally movable in a recessed seat a in the top of the guideway, as will be described, the lower extremity of the guideway terminating in the nose d hereinbefore referred to, and having a nail-passage or threat a therethrough into the side of which the groove n opens.
The guideway is slotted transversely at 71, Figs. 14: and 15, to permit the passage therethrough of the bifurcated end of a separator 0, of usual construction, to separate the nails or tacks and permit their passage singly from the groove a into the throat or passage 11 in. the path of the driver, said separator being mounted on the lower end of a lever 0, (see Fig. 0,) fulcrumed 011 the main frame at 0 and provided with a suitable roll 0 held in engagement with an edge-cam (Z in the lifting cam D (shown in section in Fig. 10 and in elevation in Figs. 7 and 8,) a suitable spring 5 retaining the roll in engagement with the cam.
The upper end of the guideway 02 is somewhat peculiar in shape, its top slanting away at opposite sides from the longitudinal groove 77., as at a Fig. 18, and above such portion the guideway is cut away to form walls a, con verging toward the groove 02 to receive the tacks or nails as they fall thereupon from the lifting device of the hopper, to be described, such nails as slide lengthwise down the converging walls n tipping as they reach the bottom, so that their bodies enter the groove 41 to travel down the same by gravity, while those nails which fall more or less crosswise upon the guideway will either fall off and back into the hopper when they reach the outwardly and downwardly inclined walls a or they will be pushed therefrom by the clearer n as it is reciprocated.
The hopper H (see Fig. 4) has at its lower end a hub 7L5, serrated or notched at its end, as at h, and surrounds the cylindrical portion of the guideway it immediately adjacent the seat D a spider h", secured to the upper end of the hopper, being mounted on the reduced upper extremity of of the guideway and held thereon by a suitable washer w and nut a so that the hopper is freely rotatable upon the guideway.
" The notched or serrated end it of the hub h engages a lug a on the clearer n and immediately depresses it against the action of a spring 5 inserted in a recess of the main frame, the free end of the spring bearing against the rear of the lug n and moving it in the opposite direction, so that a quick upward movement is given to the clearer to snap nails IIO or tacks out of the groove 71, into the guideway if the heads are too large to pass beneath the clearer, and also throwing off tacks or nails resting transversely on the guideway.
WVithin the hopper I have secured a spiral shelf h extending from the base of the 11013 per along its inner wall up to near the upper end of the hopper-body, such spiral shelf actin g to lift the tacks or nails from the lower portion of the hopper and to drop them onto the converging walls 72 of the guideway as the hopper is rotated by the mechanism described. y
A cap or cover H, having an open mouth H is attached to the upper end of the hopper through the opening in which the tacks or nails may be delivered to the hopper from time to time as necessary Without removing the cap or the hopper.
. The bearing 1) of the frame is cut away at one side to expose the lifting-cam D in or der that the pawl-tooth m may be engaged by the lug or projection 61 and the roll 0 be controlled by the cam (Z From the foregoing description it Will be apparent that the bodily-movable nailing mechanism is actuated by means of powertransmitting mechanism, the latter being controlled by bodily movement of the nailing mechanism, and that manually operated means are provided to at times connect the driver-actuating means of the nailing mechanism with the power-transmitting mechanism by or through a normally inoperative clutch.
