JAMES OLIVER, OF BALTIMORE, MARYLAND.
IMPROVEMENT IN MACHINES FOR MAKlNG DOVETAILED SHOE-PEGS.
Specification forming part of Letters Patent No. 80,053, dated July 18, 1576; application filed December 1, 1575. v
To all whom it may concern:
Be it known that I, JAMES H. OLIVER, of Baltimore, in the State of Maryland, have invented a new and useful Improvement in Devices for Forming Dovetailed Shoe-Pegs, of which the following is a specification:
The object of my invention is to provide a mechanism for cutting a notch or angular groove in peg-wood strips preparatory to the division of the strip into pegs, which, when thus divided, constitute the dovetail shoe-peg, which mechanism is fully set forth in the accompanying drawings, representing all the parts of the ordinary peg-box used in the Varney shoe-pegging machine, with the variations and exceptions hereinafter noted and explained. c
Figure 1 is a side view, Fig. 2 a top view, and Fig. 3 a section, of the machine; Fig. 4, a detached view of the angular-edged knife, and Fig. 5 a similar view of the side spring or peg-strip guard with attached roller.
A is the ratchet-wheel, acted upon by a pawl, through which motion is communicated to the shaft B, and thence to its attached feed-wheel C. D is the side spring or pegstrip guard, with attached roller, designed to keep the peg-strip within the action of the feed-wheel O. E is the knife, with a re-entering angle in its edge, having the form of an expanded letter V, with one side elongated, and designed to cut the angular groove in the peg-stri p as it passes along the peg-strip channel and between the parallel peg-strip guides. F is the pegstrip; G, the gage, to be adjusted to the width of the strip. H H are parallel upright peg-strip guides, which form the pegstrip channel, and hold the peg-strip steady and erect while passing between them. To one of these guides the angular knife E and side spring or guard D are attached, while the other supports the feed-wheel 0 and its connections;
The side spring or peg-strip guard D differs from those used in the Varney and other machines in having the roller attached, and it is so adjusted that the roller, being opposite, presses the pegstrip against the feed-wheel (J, the teeth of which wheel engage and carry the peg-strip forward into contact with the angular-edged knife E, by the action of which knife the notch or groove is cut or formed in one side of the peg-strip.
The difference in the side spring I), herein described, from the side springs in common use consists in the roller attachment, whereby the necessary pressure to keep the peg-strip in position is secured, and the friction common to the old side springs is obviated by the revolutions of the roller.
The grooving-knife, being attached by means of a screw to one of the guides H, is so adjusted that its cutting-edge projects into the peg-channel formed by the peg-strip guides H H at a cutting angle, so as to engage and groove one side of the peg-strip as it passes. This knife does not form a part of the Varney box referred to.
It is evident that when motion is imparted to the feed-wheel G, and the peg-strip F is placed between it and the side spring or guard D, the teeth of the feed-wheel engage it and carry it forward in contact with the angular grooving-knife, after which it passes under the severing-knife, and the divided dovetail peg thus formed is ready to be driven into the shoe by the driving-hammer of the ordinary shoe-pegging machine. The form of the groove thus cut in the peg-strip is such as to impart to one side of the peg a dovetail figure, diverging from the center of the notch toward each end of the peg, which is more fully described in Letters Patent granted to me for dovetailed shoe-pegs, No. 148,575, dated August 29, 1873.
This device is to be used as an attachment to shoe-pegging machines as they are ordinarily operated in shoe-factories.
Having thus described my invention, I cla-i1n-- The combination of ratchet-wheel A, shaft B, feed-Wheel 0, side spring D, angular-edged grooving knife E, gage G, with peg-strip guides H H, substantially as described, and
for the purposes hereinbefore set forth.
