Specification forming part of Letters Patent No. 51,387, dated December 5, 1865; Reissue No. 3,343, dated March 30, 1869.

To all whom it may concern:

Be it known that I, LOUIS GODDU, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Pegging Boots and Shoes, of which the following is a full, clear, and exact description.

Pegging-machines as constructed previously to my invention may be divided into two classes-viz., those in which the frame of the machine is a fixture and supports the shoe which is moved along or caused to travel in the machine as the egging proceeds, and those in which the frame of the machine is constructed to travel upon the shoe or boot as a support, the shoe or boot during its pegging being held stationary by some fixed rest,

and theframe of the machine being portable and having no connection with such rest.

My invention relates to machines of the second class; and its object is to enable sucha 1n achine, to be more conveniently manipulated to enable it to move automatically along the sole to be pegged, and to improve the construction and operation of the mechanism by which the pegs are fed and driven.

' To this end my invention consists of certain combinations of the following instrumentalities, viz, first, a portable traveling frame carrying a'spring of sufiicient strength to drive the pegging-awl and the pegs, and constructed to be supported by and to move over the sole to be pegged; second, a driving-spring to drive the awl and the peg, or either of them; third, a crank-handle,.by means of which the driving-spring is strained; fourth, a plunger to hold and transmit power to the peggin g-awl, which pierces the leather for the entrance of the peg; fifth, a stop uponthe plunger to limitthedistance to which the plunger is moved relatively to the portable frame or to the under surface of the traveling foot, hereinafter mentioned sixth, a gage to bear against the edge of the sole to .which the implement is applied, and to regulate the distance of the awl and the peg-driver, or either of them, from that edge ,seventh, a peg-tube to direct the" pegduring its driving; eighth, a pegdriver.

actuated by the driving-spring so as to drive the peg through the peg-tube ninth, a pegfeeder, or feeding mechanism, by means of which the slip of peg-wood is held and presented to the peg-driving mechanism; tenth, a knife, by means of which the pegs are cut in succession-from the peg-wood, as required in the operation of the machine; eleventh, a handle, which can be grasped .by the operator, and bymeans of which the implement is held 'by'the operator in its proper position while traveling over the sole of the shoe; twelfth, a traveling foot which is alternately rested upon the sole of the shoe or boot to support the weight of the traveling frame and to form a base of resistance for its advance, and is alternately advanced while the pegging-awl is in the leather to a new point or base for the support of the machine in a new place and for anew advance of the traveling frame and its appurtenances over the stationary sole.

Y --Th.e modein which I prefer to combine the tions. of them which I have produced will appear from the following description of a handpegging machine embodying them and from the specifications at the close of the said description.

The machine is represented in the accom I panying drawings.

Figure 1 is a perspective view of the said machine. Fig. 2 is an elevation of the lower portionof one side of the same. Fig. 3. is a vertical section of the same through the axis of the plunger. Fig. 4 is a plan of the under side of the machine, (full size.) Fig. 5 is a rear elevation of a portion of the same. Fig. 6 is;

a horizontal section of the end of the, pegtrough and the knife. -Fig. 7 is a vertical section of the vibratingfoot and its appurtenances.

In the said drawings, A is the portable frame of the machine'in suitable hearings, in which runs the shaft B, which is actuated by the hand of the user applied to the crank 0.

D is a lifting-arm adjusted and secured in place upon the driving-sh aft B by means of a set-screw. The upper end of the frame A is bored. out for the reception of a spiral drivin g-sprin g, E, which surrounds the plunger F, which is raised against the pressure of the spring E, the upper end'of the spring E bearing upon a shoulder, a, in the frame-work A, while the lower end of the spring E rests upon a block, G, which surrounds the plunger F, and is securely attached thereto by a setsaid instrumentalities'and the new combine screw. One end of the block G has projecting from it a hp, which moves in a narrow vertical groove, b, in the side of the frame-work A,

which, in connection with the guide 0 below it, guides the plunger in its movement and keeps it always in a proper position for performing its oflice.

-Within a projecting portion of the lower end of the plunger F is formed an aperture for the reception of an awl, d, and in a similar recess bored in a line with the axis of the plunger F is placed a rod or peg-driver, 0.

.After the awl d and peg-driver e are adjusted .to their proper height, they are secured'in place by their screws fg, and as they are both attached to the plunger F they have no movement independently of each other. The upper end of the plunger F projects through the frame-work A and termi-.

nates in a screw-thread, upon which turn the circular nuts H. The innermost of these nuts rests upon theupper end of the frame when the plunger F is depressed, and'thus forms a stop to limit the point to which the plunger can .be moved relatively to the frame by the action of the drivingspring E. Below these nuts H and around the plunger are placed leather or other elastic washers 7, forthe purpose of reducing the force of the concussion which takes place when the plunger is suddenly depressed by the spring E, and as the which rests on the shoulder i and is pressed forwardby the finger K, actuated by a flat spiral spring,L,pivoted at j to a circular plate, M, proceeding from the enlarged base of the vibrating beam 0, a description .of which will be given hereinafter. v

Th peg-trough, finger, and spring constitute the peg-feeder of the machine. The inner end of the peg-trough terminates in a passage, :10, for the peg-driver to work in, and

' this passage is open at one side to admit the end of the strip of wood from which the pegs are cut off separately by the knife N, whose cutting-edge; enters the peg-trough trans versely through an opening iniits side, and, in connection with thesides of the passage w, forms the peg-tube, by which the peg is di rected while being driven into the sole.

From the inner side of the frame-work A projects a stud or pin, it, upon which is pivoted a vibrating beam, 0, the base P of which is enlarged and of the form shownin Figs. 1 and 4. The under side of the base P is illclined' downward toward the lower end of the peg-tube at the end of the peg-trough, and has firmly fastened to it the inclined bar Q, which is bent to form a foot, I, through which is cut a slot, 8, for the passage of the awl and peg-driver. The under side ofthe foot I is roughened .or provided with teeth m, to prevent it from sliding when resting upon the sole of the boot or shoe to be pegged.

The relative positions of the projecting portion of the lower end of the plunger and of the foot, when the parts of the machine are properly adjusted by means of the screw-nuts H and the plunger is down, are such that the end of said portion then projects slightly be yond theuuder side of the foot, so that the foot does not then touch the soleof the shoe.

It is a gage, by means of which the distance of the pegs from the edge of the sole is regulated, the gage being constructed by preference to slide out and in on the bottom -of the bar Q, and being secured in position by the clamp-screw a passing through the slot .0 into the bar Q.

The beam 0 is provided with a slot, 11,

through which passes a screw-pin, g, which holds the lower portion of the beam 0 from separating laterally from the frame A, while allowing the beam to vibrate on the pin Ir. A flat spring, S, is secured at its upper end to. the beam 0, and the lower end of this spring bears against a projection, 31, protruding from the frame A, so that the tendency of this spring is to advance the lower part of the frame A, and thus, when the foot is stationary, move the pegging-awl and peg-driver forward in the slot of the foot 'm. The distance to which the awl and peg-driver can be so moved is determined by the set-screw s, which is screwed into the beam 0, and, projecting into the slot 11, limits the distance to which the screw-pin q and the frame, awl, and driver, connected with said screw-pin,can move forward. The spring S is strained when the egging-awl is in the leather, and the foot lis caused to advance, by the revolution of fast, the flat side of the driving-shaft is oppo-- site the plate R. Consequently the turning of the driving-shaft causes the rounded part thereof to bear against said plate, and to cause it and the beam and foot I (with which the plate is connected) to vibrate upon the stud 1:, and thereby strain the spring S while the footlis advancing over the sole ofrthe shoe to a more forward place.

The knife N is secured to the base P by means of a clamp-screw, T, the shank of the knife being constructed with an open slot, t, through which the clamp-screw passes, sot-hat the knife may be moved along the base 1? for the purpose of adjustment. knife is made flexible, and is of a width equal to the height of the passage which forms the peg-tube, against the side or shoulder t (Fig.

The blade of the 6) of which it bearsand holds the peg in place after being out. The upper part oi the frame A is formed-into a handle, U, by which the machine is held and maintained in an erect position.

Operation. The awld and peg-driver 6 being down (in which positions the flattened side 1 of the driving-shaft is Opposite the plate 1%)and the peg-trough I' being supplied with the peg-wood, the distance'to which the peg should he placed from the edg'eof the sole is regulated by the adjustment of the gage It. The operator grasps the handle or upper portion, U of the frame Awith onehand and places the implement upon the sole to be pegged, whereupon. the awl is pressed into the sole by the weight of the machine, aided,

it necessary, by the pressure of the hand upon.

the handle U, so that the end of the plunger F bears upon the sole, the foot Z being slightly above the soleby reasonof the relative adjustment of the foot and plunger before mentioned. The crank (J is now turned by the other hand andthe flattened side 1' of the driw tug-shaft is brought round underneath, (as seen in red, Fig. 7 as, by this operation the rounded part of the shaft is borne against the plate R, the beam 0 is thrown forward on its pivot k, carrying with itthe slotted foot l and knife N, while at he same time,the spring S is strained. The foot lis thus advanced, orcaused to step forward-over the Select the shoe, and the edge of the knife N (connected with the foot) is at the same time withdrawn from the peg-trough, so that the strip of peg-wood can be moved forward therein by the pressure or the spring L when the rise of the peg-driver permits this movement. The crank 0 continuing to revolve the lifting-arm 1) comes under and lifts the block G" against the resistance of the driving-spring l and the peg-driver is raised, and the awl is withdrawn from its hole in the sole, while the teeth m of the foot-piece l are brought down thereon I by the weight of the machine.

Theawl and peg'driver continue to rise with the plunger until the flattened portion rot the drivingshaft again comes opposite the plate It, when the pressure of the spring S causes the whole frame to move forward on the stud 7. as an axis, so that the plunger F, with the awl d and peg-driver c, (all carried by said frame,) are moved forward to a new place. The pegtrough, being secured tothc frame A, is advanced simultaneously with the awl and peg-driver, and as. the rise of the peg-- drivcr has nu-anwhile permitted the linger K to press the peg-wood endwisc in the trough until the end of the pogwvood fills the pegtuhe, the forwa'u'd movement of the said trough with the frame A. forces the side of the strip of peg-wood into contact with the knife N, which, entering thetrough, splits oil' a single peg and retains it in the pog-tube (SK 0 'hig. ii) in a position to be struck squarely by the driver when it descends, the flexible blade of the knife extending the whole width of the peg-wood and constantly pressing crank continues to be turned; the lifting arru' 1') passes from undeptheblock G, andzt-he spring E, being thereby released, drives the awl into the sole to punch anew hole, while the peg-driver is simultaneously driven against the peg so as to drive it into the hole tion of the crank causes arepetitionof the above ."operations, and 1 the progressive advance of the implement alongthe solo bythe alternate:v stepping"forward of the foot and awl. j

\Vhen it isreq'uircd to make the holes simply to be afterward filledwith; metallic nails, the cutting and feeding..of-the pegs: may be interrupted by arresting the motion of the; peg-feeding mechanism, and the peg-tube'and peg-driver become for the time inoperative.

The distance between the holes can be regulated by regulating the stride of the foot,

The plunger may carry an awl, or a driver, or both.
