CHARLES WV. GLIDDEN, OF LYNN, ASSIGNORTO JAMES WV. BROOKS, TRUSTEE,
OF CAMBRIDGE, MASSACHUSETTS.
HEEL-TRIMMING MACHINE.
SPECIFICATION forming part of Letters Patent No. 410,088, dated August 27, 1889.
Application filed June 25, 1888. Renewed March 7, 1889. Serial No. 802,390. (No model.)
To aZZ whom it may concern:
Be it known that 1, CHARLES W. GLIDDEN, of Lynn, county of Essex, State of Massachusetts, have invented an Improvement in Heel- Trimming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.
This invention has for its object to improve the construction and operation of heel-trimming machines of that class where the rand or oounterguard and rand-cutter are moved automatically to uncover more or less of the cutting-edges of the blades parallel to their cutting-edges. In this present embodiment of my invent-ion the rand or counter guard is supported by one rather than by two links, as in another application, Serial No. 275,880, filed by me, the employment of one link reducing the cost of and simplifying the mechanism. Herein I have combined with the rand or counter guard a treadle by which to move it positively whenever desired. I have also combined with the rand or counter guard and heel-trimming tool a wind-trunk having a telescopic bonnet.
Particular features in which invention consists will be described in the specification; and pointed out in the claims at the end thereof.
Figure 1 is a front elevation of a heel-trimming machine embodying my invention; Fig. 2, a left-hand end elevation of the same; Fig. 3, a top or plan view of the machine shown in Fig. 1, and Fig. 4 a detail of the heel or edge rest.
The main frame-work of the machine,
shaped as shown, is made hollow in the part A to constitute a wind-trunk, the hollow part A rising from a blower-shell A, bolted to a base A having suitable legs, the said base having also bolted to it suitable brackets A A, which support usual pivoted bearings A for the main driving-shaft A, one of the said brackets, as A being extended vertically to serve as a support for the wind-trunk.
The main shaft A has fast on it any usual form of exhaust-fan, whereby in the rotation of the shaft air will be drawn down through the trunk A and shell A, andto be discharged from the mouth of the said shell, as shown by the arrow, Fig. 2, the said driving-shaft containing not only the said exhaustrfambut also the driving-pulley B, which drives the belt B, extended over the pulley B and rotating the cutter-shaft B having suitable bearings 13 erected on the flanged head A The head A has bolted to it a bonnet composed of two hollow trunk portions B B, one
sliding telescopically into the other, in order that the area of the open space or mouth of the wind-trunk next the cutter may be adjusted to correspondwith the size of the cutter being used, the movable portion 13 hav ing an arm 13 connected to an adjustable block 0, in or on which is made adjustable the block 0, to which is pivoted at C the link 0 employed to support the carriage 0 provided with the rand or counter guard a, having a lip, as usual, to enter the randcrease.
The carriage O has suitable bearings for the shaft 1), having attached to its inner end a rand-cutterh of any usual construction. The carriage O has an outwardly-extended rigid arm 0, provided with a roller or other stud c, which enters a slot in an arm 0 adjustably attached by a stud or screw 0 to an arm or portion of the block 0, the adjust-x the slot in the said arm in which moves the said roller or other stud c to be placed in the desired position or angle with relation to the axis of rotation of the cutter-shaft B andthe cutter D, which with its blades may be of any usual or desired shape.
The position of the block 0 is determined by the screw-bolt 2, and according to the position of the said screw-bolt the portion B of the bonnet will enter the portion B thereof more or less, the position of the said screw being changed according to the length of the cutter being employed.
The cutter herein shown will have co-operatin g with it in usual manner a tread-guard D.
The flanged head A has erected upon it a stand d, (shown in Fig. 2,) which receives within it the reduced pin d, forming part of a lever (i (shown as of elbow shape,) one arm of the said lever having connected to ita link orrod 01 having at its lower end a roller cr other stud d, which enters a cam-slot 22 in IOC an arm 23, rising from or forming part of a treadle 24, the movement of the said treadle and cam-slot causing the lever (Z to be rocked upon its pivot This bell-crank lever d has an arc-shaped arm 25, made dovetailed in cross-section, as best shown in Fig. 3, the said dovetailed portion depending and having adjustably mounted upon it a block 26, which may be secured in adjusted position thereon by a set-screw 27. This block 26 has attached to it by a set-screw 28 a link 29, the outer end of which is pivotally attached to a post or bridge 30, in turn pivoted at its upper and lower ends by suitable pivotsorews to the link 0 so that the movement of the said lever (Z causes the said link to be moved upon its pivot C in a direction to cause the rand or counter guard ct to be moved toward or from the rotary cutter D, and at the same time that the said link is so moved the roller or other stud c, traveling in the slotted portion of the cam 0 causes the carriage O to tip more or less upon the pivot 83, which supports the carriage upon the link 0 the curve or are in which the lipof the rand-guard travels during its movement following substantially the curvature of the edges of the blades which are attached to or form part of the rotary cutter.
The heel-rest m, upon which rests the heel to be trimmed, is herein shown as provided with a shank m, which enters a hole in an arm 33, so that the said rest may be turned as about a vertical pivot.
The arm 33 is made adjustable horizontally in a lever m, and it may also be turned about its axis in said lever, and when in position it is held in place by a setscrew 3i.
The rear end of the lever m has connected to it a rod 971 provided at its lower end with aroller or other stud, which enters a cam-slot m in a portion of the arm 23, connected to or actuated by the treadle 24, before described, said cam-slot at being of such shape that when the treadle is moved the lever m will be moved, together with the heel-rest on, so
that the heel will be raised or lowered properly while the cutter acts uponthe substantially straight sides of the heel. When the rest is being actuated positively to move the heel while the rotary cutter trims the substantially straight sides thereof, the rand or counter guard is, it will be understood, tipped more or less to cover or uncover more or less of the acting edges of the blades of the cutter, especially when the cutter is trimming the substantially circular or rear part of the heel, and at such time the rest on is free to tip or turn about its pivot, so that it may remain with its acting edge substantially parallel with the lifts composing the heel. Prior to this my invention the rest m, on which the shoe is support ed and turned while being trimmed, has always remained parallel to the tread-guard or to the plane in which the tread-guard stands, and when the heel was tippedas when trimming about the rear part thereofthe said heel has had to swing on the said rest, which, when the heel is considerably concaved, has prevented the heel from taking a bearing on the rest at the point where the heel is of least diameter, and consequently the heel cannot, except with greatest care, be held steadily by the hand of the operator while being trimmed. To overcome this evil, the rest m, herein shown, has been mounted loosely upon its carrying-arm 33, as
described, so that the said rest is left free to turn on the said arm with the heel as the latter is tipped, whielris the case while the rear end of the heel is being trimmed, and consequently the heel bears at all times in like manner upon the rest on during the trimming operation.
Prior to my invention I am aware that heel-trimming machines have been provided with fixed rests-with rests that have been made adjustable in various directions; but when trimming the heel the rests have not been movable, as herein provided for.
I have herein shown a rotary heel-cutter, a carriage, a support therefor, a rand-guard attaehed to the said carriage and shaped to pro ject over the heel-cutter, a rotary rand-cutter, and a tread-guard; but I do not herein claim any one of the said devices or the combination of any one or more of the said devices, broadly, as the same form the subject-matter of several claims in my application, Serial No, 275,880, filed June 2, 1888.
I claim- 1. In a heel-trimming machine, a rotary cutter to trim the heel, and a carriage having an attached rand or counter guard to enter the rand-crease, combined with a single link, upon which the carriage is pivoted, and with a roller or other stud c and a cam with which it 00- operates, substantially as described, whereby when the link is moved toward and from the rotary cutter the carriage may be tipped to operate substantially as described.
2. In a heel-trimming machine, a rotary cutter, a carriage having an attached rand or counter guard, and means to support the carriage, combined with a treadle and connections between the treadle and support for the said carriage, whereby the carriage may be moved positively toward and from the rotary cutter, as and for the purpose described.
