To all whom t may concern.'

Be it known that I, MARK E. FERNALD, a citizen of the United States, residin at Saugus, in the county of Essex and tate of Massachusetts, have invented a new and useful Improvement in Machines for Making Casting-Patterns, of which the followingl is a specification.

The present invention relates to machines for making flanged articles, and more particularly, to a machine for making casting patterns which determine the form of the leaders used in automatic shoe machines.

It has been proposed to perform the various operations in the manufacture of slices automatically. In one system of automatic shoe machines the transfer of the point of operation of the tool along the Work is controlled by a leader upon which the work supporting jack is mounted. These leaders usually comprise a body portion having the same form on one face as the sole of the shoe mounted upon the jack and a flange on the edge of the body portion which is usually provided with teeth for engagement' with a driving pinion. The flange also acts as a guide for swinging the jack laterally to permit the tool to traverse the reverse curves of the work. One of the principal objections to the use of these automatic machines is the cost of producing these leaders which vary in size and shape with the various sizes and styles of soles intended to be incorporated into a shoe. The principal reason for the high cost of these leaders is that heretofore it has been necessary for a skilled.

pattern maker to make the pattern for casting the leader. l propose to eliminate the necessity for the employment of a pattern maker by producing the casting patterns for the leaders mechanically. I believe that I am the first to have conceived the idea for the mechanical production of casting patterns and to have devised operative mechanism for carrying such idea into practice.

The object of the present invention is to produce a machine for making flanged articles` such, for instance, as the casting patterns which determine the form of the leaders employed in automatic shoe machines.

To the accomplishment of this object the features of the invention relate to certain devices, combinations and arrangements of parts hereinafter described and then set forth broadly and` in detail in the appended clanns whlch possess advantages readily apparent to those'skilled in the art. I

The varlous features of the present inyention will be readily understood from an lnspection of the accompanying drawings showing the best form of the invention at present known to the inventor, in which:

Figure l 1s a front elevation of a machine for making casting patterns;

Fig. 2 is a plan;

Ifig. 3 is an enlarged detail in front elevation, partly in section, showing the actuation of the feed accelerator when the point of operatlon of the operating means is transferred around the ends of the blank;

Fig 4 is a detail in plan, partly in section, of the roll carrier, its support, and the feed accelerator;

Fig. 5 is a sectional plan on the line 5-5, Fig. l; f

Fig. 6 is an exaggerated lateral section of the pattern made by the machine; and

Fig. 7 is a detail, partly in section, showing the mechanism for imparting a draft to the pattern. Y

Describing now in general terms my novel method of making casting patterns which determine the form of the leaders employed in automatic shoe machines therst step consists in. the production of the blank for the foundation of the pattern. As well known to those skilled in the art it is neces sary in making a casting pattern to allow for the shrinkage in the casting. Furthermore in making a leader for a shoe machine it is necessary to allow for the spring of the last upon which the sole to be incorporated into a shoe is secured. To produce a sole-shaped blank having the shrinkage of cast iron and the spring of the last measurements accounted for I mount the sole upon a last and cause a feeleroperatively connected to a pencil to travel around the peripheral edge of the sole on the last. Interposed in the connections between the feelerand pencil is a dli'erential mechanism ywhich enlarges, by the amount of the shrinkage of an iron casting, the movements imparted to the pencil by the feeler. By this means a sole-shaped area is traced having the shrinkage of cast iron and the spring of the last incorporated therein. With this sole-shaped area as a guide a flat wooden` blank is made having the same size and shape. This sole-shaped blank is then inserted into vmy novel machine which is provided with a rotatable support for the blank, devices for supporting, guiding and feeding a strip of material, such as paper, and a pair of rolls for attaching the paper to the peripheral edge of the blank and Winding the paper in layers thereon to build the guiding flange. The rolls are mounted on a carrier which tips automatically as the point of operation of the rolls is transferred around the reverse curves of the blank to maintain the rolls substantially normal to the point of operation. This carrier is mounted on a swinging support which swings automatically during the rotation of the blank to permit the rolls to travel around the toe and heel portions of the blank and reach the shank portions thereof. The machine is also provided with a feed accelerator which imparts an additional pull upon the supply end of the paper so that the paper may be attached to the shank portions of the blank While the paper is free from tension. After the pattern is completed by this machine the draft necessary for the removal of the pattern from the sand is imparted to the pattern by a second machine which is provided with a series of rolls which simultaneously support, guide, feed and operate automatically upon the pattern to impart the draft thereto and remove any roughness on the top and bottom faces of the flange. The pattern is then provided with a coat of shellac.

' In `the illustrated embodiment of the invention a sole-shaped blank 1, (Figs. 1, 3 and 5), provided with a pair of holes 2. (Fig. 5), is slipped upon a pair of pins 3 carried by a. plate 4 which is pinned to a horizontal shaft 5 journaled in a vertical plate 6, (Fig. 1), of the machine frame. The shaft 5 is driven during the operation of the machine to rotate the blank ina contra-clockwise direction from a countershaft 8, (Figs. 1 and 2), one end of which is journaled in the plate 6 and the other end of Which is journaled in a bracket 9 carried by the frame. The countershaft 8 carries a gear 10 which meshes With a gear 11 carried by the shaft 5. The countershaft 8' is driven from some suitable source of power through a bevel gear 12, (Fig. 2), on the shaft which meshes With a bevel gear 18 carried by a vertical shaft 14. To permit the shaft 5 to be rotated manually by a hand Wheel 15, (Figs. 2 and 5), pinned thereto the gear 10 is formed on a clutch sleeve 16 (Fig. 2), which is driven from the shaft 8 through a clutch spline 17 carried thereby. The sleeve 16 and spline 17 are disengaged by a lever 18 having an operating handle 19 vat one end and connected at its other end to a post 2O which is loosely mounted in a vertical bear- :masas ing 21 formed on the bracket 9. The spline 17 and lever 18 are connected by a semicircular shoe 22, pivotally mounted on the lever 18, which travels in a cylindrical slot formed in the spline 17.

In order to clamp the blank upon the driving plate 4 a bracket 7, (Figs. 1, 2 and 5), carries a longitudinally movable post 23 upon which is mounted a rotatable plate 24, (Fig.'5), provided with a pair of holes for fitting over the pins 3 which project from the plate -t through the holes inthe blank. The plate 24 is held in clamping position by a. spring 25, (Figs. 1 and 5), one end of which is connected to the plate 6 and the other end of which is connected to a lever 26 pivoted at its lower end to an arm 27 pro]ecting from the bracket 7. Intermediate its ends the lever 26 is pinned between the arms 28 of a slot formed in the end of the post 23. To permit the unclamping of the blank and the locking of the plate 24 in an inoperative position the lever 26 is provided with an operating handle 29 and a dog 30, pivoted upon the lever 26, and arranged to snap behind the bearing for the post 23 when the post is moved by the operative to withdraw the plate 24 from the blank.

Before the blank is rotated one end of a strip of tacky paper is attached to the edge ot' the blank. A pair of tools is then broughtdown upon the attached paper one of which guides or lays the paper in position upon the edge of the blank during the rotation of the blank and the other one of which fixes 100 or sets the tacky paper in a permanent position. The paper laying tool comprises a flanged roll 32, (Figs. 1 and 3), which is journaled in a roll carrier 33 centrally pivoted on a stud bolt 34 secured to a support- 105 ing arm 35 which is pivoted at 36 to the machine frame. The rollVr carrier also carries the fixing tool Which com )rises a roll 37. The rolls are normally held away from the blank to permit the initial attachment of the 110 paper thereto by a spring-actuated pivoted dog 38, (Fig. 1), carried by the arm 35 and arranged to engage a lug 39 carried by a curved guide 40, secured to the plate 6, the arms of which loosely embrace the arm 35.

The paper for the blank may be presented thereto in any suitable manner found desirable or expedient. In the illustrated embodiment of the invention the strip of paper, provided on one face With a normally non- 120 adhesive coating, is carried by the machine in the form of a roll 41 the usual Wooden core of which rotates freely onthe hub of a stationary reel, (partially shown in Fig. 1). The strip of paper from the roll is led 125 the machine frame.

musea in bearings formed on the cover of the water tank 44 and the other ,end of which is journaled in bearings formed in the plate 6, (Fig. 2).

In order to render the coated face o f the aper tacky the roll 45 is provided with a elt rim 47 which, as it passes beneath the Surface 48 of the Water in the tank 44, becomes saturated with suiiicient moisture to thoroughly wet the coated face of the paper when the paper is pressed. against the felt rim. The paper is pressed against the felt rim 47 by a second roll 49 mounted on a Ishaft 5 0 journaled in the legs of a bifurcated arm 51 which is ivoted at 52`n the plate 6, (Fig. l). A nger 52a dependlng from the arm 51 insures the contact of a substantial length of paper with the roll 45.

The roll 49 is normal-ly pressed against the paper on the roll 45 by a coiled spring 53 one end of which is connected to the arm 51 and the other end of which is connected to The shafts 46 and 50 carry gears 54 and 55 respectively normally intermeshed so that, as the paper 1s fed by the rotation of the blank to which it is attached, the rolls will rotate together.

In der to separate the rolls When the opteratin tools are held out of their operating position so as to permit the ready introduction of the paper between them the arm 35 carries a pin 56, (Fig. 1), Which, as the arm separating the rolls 45. and 49 and discon necting the gears 54 and 55.

After the paper has been rendered tacky by the inoistening apparatus the paper is led over the roll 49 to bring its tacky face uppermost and is then led over a roll 58 and. between a pair of pins 59 mounted on a plate 60, (Fig. l). The plate 60 normally rests at one end upon a pin 61 carried by the arm 35, (Fig. 1), and at its other end is bifurcated (Fig. 4) so that it may straddle the roll 37 and rest upon the upper face of the roll carrier 33. Connected to the rear of the arms of the bifurcated plate 60 is a pair of lugs 62 by means of which the plate 60 is pivoted upon the stud bolt 34. The paper is then led, between the roll 32 and a bridge 63, (Fig. 4), on the roll carrier 33, to the point of operation at which point one end of the tacky paper is attached to the blank.

After one end of the paper has been initially attached to the edge of the blank and the operating tools depressed to engage tips on the bolt 34 to maintain the tools substantially normal to the point of operation as illustrated in Figs. 1 .and 3. As the blank being operated upon is sole-shaped there is a tendency for the paper to drum-head across the shank portions of the blank owing to the tension placed upon the paper by the rotation of the blank. To overcome this tendency the roll carrier 33 as it tips to maintain the rolls substantially normal to the oint of operation at the toe and heel portions of the blank actuates the plate 60 in the manner illustrated in Fig. 3 to pull upon the supply end of the paper so as to produce slack in the paper and thus enable the rolls to attach the paper to the shank portions of the blank While the paper is free from tension, (Fig. l). The plate 60 returns, under the influence of gravity, to its original position as soon as the carrier tips in the opposite direction during the transfer of the rolls along the shank portions of the blank, (Fig. 1). The plate 60 is herein called a feed accelerator as it accelerates the feed of the strip due to the rotation of the blank.

During the transfer of the point of operation of the tools around the blank the arm 35 which supports the roll carrier 33 swings on its pivot 36 to permit the rolls to travel around the ends of the blank and reach the shank portions thereof. As illustrated in Fig. 1 the axis ofthe rotating blank 1 and the axis of the carrier 33 are located at equal distances from the axis of the support 35. This construction permits the rolls to rise and fall under the influence of the rotating blank Without danger of binding or producing excessive pressure as they reach the toe and heel portions of the blank. It Will also be seen from an inspection of Fig. 1 that the journal for the roll 32 is located a greater distance from the axis of the carrier 33 than the journal for the roll 37. By locating thevjournals for the rolls 32 and 37 at different distances from the axis of the tipping carrier in the manner described most of the Weight of the arm 35 and its supported parts is transmitted through the roll 37 to the Work. This manner of mounting the rolls 32 and 37 insures the operation of the roll 32 under a light pressure to lay the paper in position and the operation of the roll 37 under a heavy pressure to ix the paper laid by the roll 32.

The blank is'rotated until a ilange of the desired thickness is built upon theedge of the blank at which time the supply end of the strip of paper is severed and the pattern removed from the machine. This pattern is illustrated (greatly exaggerated) in section in Fig. 6. As shovvn it consists of a body portion 64 comprising the sole-shaped blank and a laminated flange 65 which has been built upon the blank by winding a strip of paper in layers around the peripheral edge of the blank.

In order to impart the draft to the pattern and smooth the irregularities on the top and bottom faces of the liange the pattern is passed through a machine provided with a series of rolls which support, guide, feed and operate automatically upon the pattern as it passesv through the machine. As shown in Fig. 7 these rolls comprise a pair of rolls 66 and 67 which engage the top and bottom faces of the body portion of the pattern respectively and which are also constructed and arranged to engage the inner faces of the flange and impart the draft thereto, a pair of rolls 68 and 69 which engage the top and bottom faces of the flange respectively and smooth the irregularities thereon, and a fifth roll 70 Which engages the outer face of the flange and imparts the draft thereto.

While the invention has been illustrated and described as being particularly useful in connection With a machine for making casting patterns it will be apparent to those skilled in other arts that the general organization of the machine, together With various features of the mechanism by Which the parts are operated, are applicable to machines for. making other kinds of flanged articles.
