Description
Letters Patent No. 113.684, dated April .11, 1871.
MoULToN, orv LYNN-MASSACHUSETTS.
iNiPROVMENT iN HEEL-TRINIMING MACHINES.
The Schedule referred to Lu these Lettere Patent and making part of the mame.
I, JOHN Q. Moni/roy, of Lynn, in the 'State of Massachusetts, have invented an Improved Heel-trimming Machine, of which the following is a specification.
The invention consists in the use ofp, revolvingknife so placed, relatively to the carriage for the boot, ns to cut the heel from top to bottoni or from bottom to top, the center ot' revolution of the knife-bladcs being at right angles, or nearly so, to the center of revolution of the heel, instecd of the two centers being parallel, as in other machines where revolving knives are used.
It consists, secondly, in the peculiar construction of the knife, whereby a drawing cut is made, and whereby the danger of pulling apart the layers of the heel is obviated. l It consists, thirdly, in an improved carriage or holding mechanism, and in a combination of the sume with the cutting apparatus and the gauges for determining the bevel of the heel. Y
In the drawing- Figure l is a. front elevation of the machine.
Figure 2 is a vertical section showing the parts of the machine to the left of the dotted line in fig. l.
Figure 3 is a plan.
Figure 4 is a detailed view of m'part of the carriage on an enlarged scale, Y
A is the frame.
B is arest for the revolving carriage or holding :neolianxsm.
The rest is supported by two arms, C O, secured to the frame of the machine, as hereinafter described.
D in a plete forming the bottom of the carriage, and revolving upon a pin, a, by which it is secured to the rest, as shown.
E E are two bent bars forming the principal part of the carriage, and firmly secured to the plate D by screws. These bars meet above the frame of the machine and there support other mechanism, to be described.
F F are two curved plates, as shown, to grasp the upper ofthe boot just above the heel, and emhracing the bootsleg. The plates F F open and shut, be-
ing hinged together at the reer, as shown. They have each, at the bottom, ay ange resting upon the plate D.
A pin, e, passing through the anges at the rear, as shown, secures the hinged plates to the plate D, while it also serves as :t pivot upon which they open and shut. When closed these hinged plates form one of the patterns. Their ripper edges are bent so as to tit into the rand of the boot between the heel and the upper.
These anges thus formed serve as a guage to determine the first position of the boot when it is introduced into the machine, and as n protection tb ,the
upper. If theyit properly the hoot does not Vrequire a. lust.
` The flanges of the hinged plates which rest upon the plate D extend up in front into two levers, the ends of which work in two cam-grooves, corresponding to each other, cnt in the shaft G, which has hearings in the bars E E, and is turned back and forth by the wheel g, as shown.
His a. pattern-bur, n horizontal section of which, where it comes into contact with the gauge O, to be hereinafterdescribed, has the contour of the tread of the heel.
The upper part is attached to the bars E E by pins working in the slots s s, thus allowing a. vertical :novement to the pattern-bar.
The position of the puttcrnbar is determined by the lever J, as shown upon an enlarged settle in iig. 4.-
The lever J is pivoted to the bars E E by the pin m.
The lever J has a. slot, t, in which works a piu which is fixed in the slot n in the ripper part of the patternbnrH. (See figs. 1 and 4.)
K is a revolving knife whose shaft has bearings n the standards L L`attaobed to tho main frame, as shown. To make this knife, deep und wide screwthreads are cut around e cylinder, and to the projections remaiuing between the threads are secured steel blades, as shown.
The knife is revolved by belts n n passing around the cylinder or shaft and two pulleys, Y Y, upon the main shaft X, as shown.
The standards L L also support two gauges, 0 and P, against the former of which is held the pattern H, and against the other the pattern formed by the hinged plates F F, in a. manner presently to be described.
The gauge 0 is secured to two pins passing through the standards, as shown. Each pin is cut as a screw,
.and is furnished with two nuts by which the position ofthe gauge is determined horizontally. In like manner the position of the gauge P is determined by the nuts c c. The relative position of' the two gauges, when the machine is in operation, determines the bevel of the heel.
V V are two screws passing through rings in the y arms C C, and furnished with nuts yw y1v 1b' 10 t0 deterinine the vertical position of the rurriagc.
The screws V V have arms x a; which pass through holes in the slides z z, which tra-vel hack and forth ou ways in the main frame, :1s shown.
R R are spiral springs attached to the slidesz: und the frame in such manner as to cause the patterns of the carriage to press against the gauges O und l.
The operation is as follows:
The hoot is placed, heel'upward, between the hinged plates, the log extending down between the hinged plates, which are closed by turning the wheel g until the boutis Iirmly grasped by the upper edges of the plates tting into the rand of the boot.
The leverJ is then brought forward until the patternbar H presses with sufficient force to prevent any movement of the boot independently of the carriage.
The vertical position of the carriage is then deteriilined by the nuts 'w w w w, so as to bring the heel into contact with the knife. These nutsalso determine, to some extent,l the vertical shape of the heel, since the knife, unless ot' very large diameter, makes a concave cut.
The required bevel is then determined by the gauges O and P, as before directed.
The carriage is next turned to the extreme right, I
and the main shaft being set in motion by any suitable means the carriage is turned from right to left by the vhand of the operator.
The arms a; a: allow to the carriage a slight inovement to the right or left, whereby the operator may make slight variations in the length of the heel.
After one heel has been trimmed, to trim another of ai lboot or shoe of the same kind further movement of the nuts w, or c, or c will be necessary.
The operator has only to exercise snicient care to cause the upper edge of the hinged plates F F to t into the rand of the boot.
The screw-form of the knife-blades permits adraw sented as revolving forward. It is obvious that either or both edges of the blades may be sharpened and the knife revolved either way, the carriage being turned accordingly.
I claimv 1. A revolving knife, in a heel-trimming machine, whose axis is at right angles to the center of revolution of the heel to be trimmed, substantially as described.
2. The plates F F, formed and operated substantially as described, to determine the position of the boot, and to serve as a guide and protect the upper.
3. The plates F F and pattern-bar H, in combination, to h old the boot without the aid of a last.
4. The plates F 'F and pattern-bar H, in com-bination with the knife K and gauges O and 5. In a heel-cutting machine, a revolving knife made in the form of 'a screw, substantially as described, for
the purposes described.
