This hole serves to for a blow, Fig. 5, same as Fig. at, with the reduce the weight of the plunger and at the awl driven, the peg out off and moved under same time forms a pocket which carries and the driver readyfor the continuation of the guides the raisin -spring B Central with the stroke to withdraw the awl and drive the peg hole B through two of the sides of the plun- 50 Fig. 6, same as in Fig. at, except that the parts ger B are the slots 13 wide enough to allow :00

the bolt A to pass freely through and long enough to'allow the desired reciprocation of the plunger B. \Vithin the hole 3 is the raising-spring B with its lower end resting upon the bolt A and when the top of the plunger is closed by the cap 13 the spring acts against the inside of the cap and raises the plunger.

From the foregoing it will be seen that to remove the awl or driver from the machine it is only required to take off the cap B and withdraw the bolts A and A, when all parts of the machine can be quickly reached.

To the lower solid end of the driver-plunger B are secured the peg-driver B a wedge or cam 13 for operating the feeding device, and

the pin 13 for operating the swinging lever D.

The awl-carrier C is also rectangular in form and when in the machine one of its sides contacts with and slides against one of the sides of the driver-plunger B, as shown by Figs. 4, 5, 8, and 9, the awl C and peg-driver B beingsecured to these contacting sides, so that they will also contact and slide upon each other, as shown by Figs. 14 and 15. This awlcarrier is operated by the driver-plunger so that it will make one full reciprocation and drive and withdraw the awl when said driverplungeris descending by the following attach ments and connections:

Pivotedto the upper end of the awl-carrier C at C is the pawl having the downward extension C against which the spring 0 operates to press the end of the pawl toward the driver-plunger, as shown by Figs. l and 8. A tooth or notch is formed on the driverplunger at B, so that it will engage with the end of the pawl 0 when said plunger is raised to its highest position, and as the plunger descends it moves the awl-carrier down and drives the awl into the stock.

There is formed upon or attached to the part A of the casing the stationary cam A which engages with the downward extension 0 of the pawl C and which completely disconnects the upper end of the pawl C from the tooth B when the awl-carrier has been moved down the proper distance and leaves the various parts in the position, shown by Fig. 5, from which point the continued descent of the driver-plunger withdraws the awl from the stock by the following mechanism:

In a suitable recess formed in the main part of the casingA back of the plunger and awlcarrier there is hung upon a part of the bolt A the compound swinging lever D, as shown in Figs. 4, 5, 6, 7, 8, and 9. This lever is so shaped that as the driver-plun ger moves down from the position shown by Fig. at to that shown by Fig. 5 the pin B fixed in and moving with said plunger, will not change the position of the lever. As the descent of the driver-plunger continues below the position of Fig. 5 the pin B engages with the working face of the lever D and swings it to the left. When the driver-plunger has nearly reached its lowest position, the lever D has been swung to its extreme limit'of motion. This motion of the lever D is transmitted to its upper extension D, which engages with the roll 0, which is connected to the awl-carrier by the pin G and raises the awl-carrier and withdraws the awl from the stock. There is also a downward extension D from the lever D, which as the driver-plunger is ascending engages with the pin 13 and swings and holds the lever D to its extreme limit of motion to the right ready for another descent of the driver-plunger. To give the pin 0 fixed in the awl-carrier 0, suitable stability to resist the strain of raising the awl-carrier, the slot A is formed through the main part of the casing A and the outer end of the pin 0 is flattened to slide therein, as shown by Figs. '7 and 8.

The throat of the machine E has attached to or formed upon it the dovetail slide E, which is fitted to the groove A of the casing A, and this throat is secured in position by the bolt A which passes through the hole E The guideway for the peg-wood, as shown by Figs. 3, 11, and 16, is placed so that the line of travel of the peg-wood through it toward the driver is at right angles thereto. From. the inn er end of this pegwood the pegs are sheared and then moved by the swinging shear F into the throat. The shear F is se cured to the swinging arm F, which arm is hung upon the head of the bolt A by the pin F and the arm F is connected to the awl-carrier C by the link F and proper pin connections, as shown by Figs. 1, 2, l, 5, and 6. As the awl-carrier moves down a peg is cut from the strip and moved into position to be driven, and when the awl-carrier moves up the peg-shear is swung back, so that another length of peg-wood can be moved forward by the feed-pawl E to be in turn cut off. The swinging part of the shear cuts against the stationary shear F secured in the bottom of the guideway for the peg-wood, as shown by Fig. 7. To hold the swinging shear up to its work and also to form a path for the peg to swing in while moving into position to be driven, there is secured to the throat the L-shaped piece E Figs. 1, 2, 4, 5, 6, and 10. The peg-wood is fed up to the shears by the scratch feed-pawl E Figs. 10, 11, 12, and 13, which is pressed forward by the spring to feed the peg-wood and pressed back to take a fresh hold thereon by the wedge or cam B, which at the proper time passes down through the, hole E formed in the throat for that purpose and so positioned that the cam B just clears the top of the pegwood. The cam B is made of such length that it will not move back the feed-pawl E until the preceding peg has been driven sufficiently far into the work to be withdrawn from the nozzle G when it is moved from the place where the machine was operated.

The peg-wood feed-pawl E is hung under the guideway upon the pin E and is provided with the slot E which allows it to have the requisite motions, and the spring E acts upon the pawl in such a manner that it serves to press the points of the pawl up into the peg-wood as well as to move it forward. The retainer-pawl E is hung upon the pin E so that its point is in contact with the peg-wood about the width of one peg back of the place where the points of the feed-pawl E will engage with said peg-wood, and the spring E presses the point of this retainer-pawl up into the peg-wood and prevents backward motion thereof when the cam 13 is operating.

After the peg has been sheared and moved under the driver it is held in position by two adjoining sides of the throat, the face of the shear, and one side of the awl, with the end of the driver just in contact with its head, as shown by Fig. let. IVhen the continued descent of the driver has moved the peg a short distance down, the awi commences to move up and the peg is carried into the nozzle of the machine, where it is guided by the two opposite sides of the nozzle G, on one side by the awl and on the other side by the registerpoint G, hung upon the pin G 14 and 15. A spring G secured to the under part of the throat E by the screw G, holds the register-point up to the side of the awl, until the peg, pressing between the awl and registerpoint, moves said peg over to reach the hole made by the awl. When the point of the peg has reached the stock into which it is to be driven, the awl is nearly withdrawn from the stock and the register-point has moved the end of the nozzle G over the hole just made by the awl and into which the peg is then driven, as shown by Fig. 15. This arrangement of parts of the peg-delivery mechanism causes the peg to be fairly driven no matter at what inclination the operator may hold the peg-driving machine.

Having thus described our invention, its construction and mode of operation, we claim and desire to secure by Letters Patent of the United States 1. In ahand peg-driving machine, the combination of easing carrying and guiding suitable awl and peg driving mechanism consisting of two parts connected by dovetails, a

swinging lever pivoted between said parts, and a bolt holding said parts fixed in position, and upon which said lever is pivoted substantially as shown and described.
