IMPROVED PBGGING MACHINE.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, EDGAR M. STEVENS, of Boston, Massachusetts', have invented certain improvements in Awl-Feed Begging Machines, which are described andvrepresented in the following specification, and accompanying drawing, which gives a sectional view of my machine.

My invention relates to a method of feed-ing the work, in combination with other'peculiarly arranged parts of such machines, and consists among other things in feeding the work by a movement of the awl when it is connect-ed with a head so hung as to conform to the surface curvatures of Ythe sole; and its object is to secure perfect and uniform pegging round short curves or otherwise. This is attained by a combination of the vibrating awl when used asa feeding instrument .with a sliding swinging head, which supports the pegging mechanism and presents it properly to the work.

In the drawing, A is a casting, which forms a head or support for the pegging mechanism. It has pivots B by which it is hung in slides or ways y y, in which the pivots or axes B B can move upand down, so that it can swing as well as slide, (or it may be made to slide sideways, as well as up and down.) C is a cam-shaft connected to a driving-wheel by a `ioint-link or otherwise, which will permit the various movements of the head while itrotates the cam-shaft. D, shown by red lines, is the cam by which the awl-bar E is raised.- shown by blue lines, is the cam which gives the awl-bar its sidewise movement. Cr, shown by black lines, is the cam which lifts the peg-driver bar H. The downward movement of the awl and peg-driver is given by the contraction of suitable springs, when by the rotation of the cams the projections from the bars are allowed to fall from 4the points D and G. These springs areattached by one end to A. (The awll and peg-driver may he driven down by means of cams or Weights acting as hammers.) The pins a Ia acting on the inclined slots in the pegdriver during its vvertical movement give it a sidewise movement, so that the awl-bar will'notl interfere with it, end so that in the last portion of its rise it will act on the lever b, which acts on the catch c, and liberates the peg-tube ci when the spiralspring e draws it to the position shown in the drawing, or the lever band catch c may be dispensed with, and the lever z' he divided into two parts pivoted together at m, andthe lower part pivoted to the frame at 1t, in which casethe depression of the bent part of lever z' by the pin will cause the lower part atl i to move the knife-barj to the left and cut'the peg, and the spring k will return it after it has done its duty. The awl will strike through the peg-tube carrier d to the left of the peg-tube as it descends, and as it moves laterally it will carry the peg-tube to the right. The withdrawal of the awl will liberate the peg-tube and allow the spring e to draw it back to its proper position for the action of the peg-driven; The awl-bar E is guided in its rise 4and fall by the pinsff fitting in slots therein. These pins are fixed in a sliding frame which is guided by suitable ways formed in the head. Another pin, g, fixed in the same frame, projects from it into 'the cam F, 'which in itsv rotation by the vmeans described gives the sideways or feeding movement of the awl. The pin h acts on the bent llever z', which actuates the knife j by which the pegs are split from the peg-wood. The spring c also acts on the lever t' to return it to the position it occupied before the -pin L moved it. The peg-tube cl is secured to the head by suitable Vslides and ways, and is brought forward by the forward sidewise movement of the awl when it feeds the work, so that the recess cut therein for the reception of the peg when cut from the wood, and through or into which the awl and pegdriver pass, will be in the place indicated by red lines. In this movement of cl it will raise the catch or latch c, which is so arranged that a spring, Z, will throw the latch c down holding the peg-tube against the action of the spring e during the driving of the peg, and until the pegilrivcr is raised nearly to its full height. The peg-carrier is represented as broken from the head, as it does not differ from the common peg-carriers. e

The order of driving apeg is as follows: Premisingethatthe cam D is nearly in the position shown in the drawing, rotation of the shaft C causes the awl to come down throughV the peg-tube into the work; it is then moved forward by the cam F, then raised by the operation of'the cam D, and then moved back sidewise by the camvI During these operations the pin h has withdrawn the knife and held it until the peg-wood was forced into the tube, when the pin rotating beyond the lever z', the spring 7c forces the knife 7' forward, splitting the peg from the wood and forming the fourth side to the peg-tube. The driver now descends and drives the peg in the' tube, and at once resumes its former position, in doing which it acts on the lever b, which raises the latch c, whichis then moved by the spring e under the nwl, and the next rotating of the cam-shaft repeats the operation. When the peg-tube is so placed that the recess cut therein for the reception of thepeg is at'the place indicated by red lines, the knife is Withdrawn long enough to permit the peg-wood to be forced forward-the knife then advances, cuts the peg from the Wood, and remains in this position, formingr the fourth side of abox enclosing the peg that it may be driven withoutA being bent or broken.

' As'my invention has reference to n sidewise movement of the :Lwl when used for feeding the work, when combined with n. bend for supporting the pegging mechanism, which has a. sliding, or sliding and swinging move-- ment, or a, vertically-and laterally moving head, 'I do not desire to limit myself to my partieuinrly described mechanism, but have regard t analogous or equivalent devices for producing similar results in machines operated by wheel treedle o1' power, and distinct from hnnd-peggers.

YVhat I claim, therefore, and desire to secure by Letters Patent, is-

l. The combination of a. vibrating moving awl with a. sliding or vertically moving head, substantially as described.

2. Combination of the feeding-:MV1 with the sliding and swinging bend, substantially as set forth.
