HEEL-BREAST-TRIMMING MACHINE.

To all whom it may concern.-

Be it known that 1, Louis G. FREEMAN,

a citizen of the United States, and resident.

of Cincinnati, in the county of Hamilton and State of Ohio, have invented an Improvement in Heel-Breast-Trimming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention is an improved ma chine to trim or cut the heel breast-s of boots and shoes, particularly the curved heel breasts such as Louis heels, half-Louis heels, and the like. Such heels are made in a wide variety of curving breast portions, particularly where the heel is oined to the shank, and this curved portion presents an unusually diiiicult surface to be cut. The prior machines using straight heel breasting knives could not be employed on Louis heels, excepting possibly for a very short distance from the-toplift inwardly until the curved portion is reached. As the trimming of such heel breasts by hand was an extremely difficult, expensive and unsatisfactory method, several attempts have recently been made to develop a machine for doing such work, but which have not fulfilled the requirement or possessed a range to meet the wide variety of Louis heel breast styles nor for rapid commercial work. It is an object of my present invention to provide novel means to hold and support the shoe; to employ removable guards or templets secured on the shoe jack adjacent the heel to cooperate with means adjacent the cutting tool to control the relative movement between shoe and cutter in any desired curve or line; to improve the heel supporting jack and clamp; to provide an automatic guard between the cutting tool and shoe, to prevent any injury to the shoe; and various features of adjustment.

A specially important feature in my present machine consists in the arrangement of the cutter, the adjacent guards for the templets to control the curve or line of cut on the heel breast, and the exhaust pipe so arranged with relation to the cutter as to Specification of Letters Patent. Patented S t 28 1920 Application filed June 15, 1917.

Serial No. 174,824.

constitute a guide or guard for the shoe shank, preventing the cutter from marring the shank, while permitting the completion of the cutting or trimming action on the curved heel breast directly up to the shoe shank and the relative rocking movement of the shoe and cutter to permit trimming the heel breast at each outer edge of the heel to a pattern. This combined dust hood and guard enables the machine to trim the curved heel breast right in to the joint be tween the breast and the shoe shank, particularly in the full Louis or half-Louis type of heel, entirely eliminating any hand work and finishing the heel in this particular at a single operation.

Another object of the invention is to provide jack devices for holding the shoe and for presenting the parts to be trimmed properly to a rapidly rotating cutter, in which the work under universal motion can be moved to and from the cutter, in a direction tangent to the cutter for feeding the work as it is being trimmed, and sidewise for edge rounding, with all the motions guided for producing a predetermined finish of heel and limited or guarded to prevent injury to the shoe. My improved machine eliminates the services of a skilled operator and enables the work to be accurately and rapidly done with ease and convenience for increasing the capacity, producing higher quality of work and uniformity in the finished product.

Additional features of the invention. novel combinations of parts and details of construction will be hereinafter more fully pointed out and claimed.

As the use of the machine is principally for trimming heel breasts of boots and shoes and particularly to a class of heels known as Louis or half-Louis heels of ladies wears,

in which the breast follows a straight and curved configuration developing into a curved line meeting with the shank of the shoe, and in which the side edges of the heel at the shank are rounded, the description of the machine as to its mode of operation will be confined to such particular use.

The shoe, sole and heel upward, is clamped at the heel upon a jack with the toe of the shoe engaged upon an adjustable toe rest carried by the jack, the jack normally occupying a position forward and downward from a rotary'cutter, locating the parts for convenience to the operator, so that he can quickly insert and remove the shoe from the jack, and freely operate the various parts so that the work can be performed with speed and accuracy. I

The jack is arranged to provide for universal motion, rearwardly and upwardly toward the cutter for presenting the heel to the cutter and also to be moved sidewise to swing the shoe in an arc for a rounded finish at each side, of a shoe bisecting l1ne drawn from heel to toe. The ack, after the shoe has been clamped thereon, is moved toward the cutter, and its limits of motion are controlled by guard and templet devices to trim the heel breast to conform to a predetermined configuration.

Referring to Figs. 1 and 2 of the drawings, 1 indicates the base of a column 2 upon which the various parts are mounted and journaled. The upper portion of the column is of yoke design providing two spaced arms furnishing bearings for the cutter shaft 3, over arm or bar 4 which supports an exhaust snout for carrying off the trimmings, and a second shaft 5 as a countershaft for grinder devices used in sharpening the cutter on shaft 3.

A shaft 7 journals in bearings formed at the base of the column provided with a pulley 8 having a belt 9 connecting with a pulley 1O fixed upon the cutter shaft 3. Transmission devices for controlling the rotating of the shaft 7 are shown in Fig. 1 comprising a tight and loose pulley 1111, a belt 12, and a belt shifter 13, which, however, may be of any commercial design or type.

A grooved pulley 14 is fixed upon the shaft 7 belted to a pulley 15 on the grinder counter shaft 5 for rotating the grinder device 16. The grinder devices are arranged to swing and bring the grinder wheel into cooperation with the cutter. But, as the grinder devices are auxiliary to the machine no detail description thereof is made herein. The machine may also include other shoe or heel finishing devices as auxiliaries to the heel breasting devices and as is included in the drawings, Figs. 1m 4, transmittingly connecting with the cutter shaft 8, but as they do not form a part of this invention description thereof will not be included.

One end of the cutter shaft 3 projects beyond the bearing yoke of the column, to which a cutter 18 is fixed. This end of the shaft 3 is provided with a journal strap 19 connecting said shaft with the over arm or shaft 4. The strap or arm 19 has a sleeve at each end for respectively receiving the shaft 3 and the shaft or rod 4. The sleeve engaging with the rod 4 is split to enable it to be frictionally clamped to the rod 4. The strap stabilizes the cutter shaft 3 against vibratory motion when 'revolved at the high rate of speed necessary or essential to the cutter for making a clean cut.

Gutter.

The cutter 18 as shown in Fig. 4 represents a type having removable cutter blades, while as shown in Fig. 9 the cutter has its cutting edge formed integral therewith, and this latter form is the more preferable as the diameter of the cutter is standardized for a determined radius of heel breast curve at the juncture of heel breast and shank, using a different diameter cutter for each different radius of heel breast curve, and to the trade offers many advantages over a removable blade type of cutter, it being regarded that the shoemaker as a rule does not possess the skill of a mechanic to make the necessary machine adjustments. The cutter is shown as of double cutting edge type with the cutting edges diametrically disposed and of a selected diameter to give the proper degree of curve at the base of the heel breast where it joins with the sole shank portion of the shoe as disclosed in Fig. 9. The breast portion of the heel is trimmed to any angle or line desired or as may be regarded as proper in the shoe cut relative to swing of last or shoe, by a movement of the work in a direction parallel with a diametric line through the cutter so that the work is brought tangent to the rotation of the cutting edges and such trimming may be either in a straight, curved or irregular line depending upon guide or cam outline of templets attached to the jack to be hereinafter described.

The cutter is removed by loosening and disengaging the shaft brace strap 19 from the end of the shaft 3, and sliding the cutter endwise of the shaft. The brace strap 19 is easily adjusted and centered with the shaft axis and alined with the shaft bear ings upon the column.

Universal motion shoe supporting jack.

20 indicates a counterweight jack supporting and actuating lever pivotally mounted within a girdle bracket 21 fixed to and longitudinally projecting from the column 2. The rear end of the lever is provided with a weight 22 to counter-balance the weight of the jack devices supported upon the forward end of the lever. The downward swing of the forward end of the lever 20 is limited by a stop screw 23 threaded through a lug 24 projecting laterally from the bracket 21. (See Figs. 4 and 9.) A pair of arms 25 project from the forward end of the lever 20 to and be tween which a rocking jack cradle 26 is pivotally supported. This cradle is of curved form, extending upwardly from its fulcrum, and provides a swived support for the rocking jack 27. The rocking jack 27 conforms to the shape of the cradle 26 and is capable of being swung to the right or left independent of the cradle and with the cradle as a unit forward and backward upon the lever 20, and the jack 27, cradle 26 and lever 20 move as a unit in presenting the shoe heel to the action of the cutter. The unitary motion of jack 27 and cradle 26 provides for bringing the parts forwardly upon the lever and away from the cutter to a position where the shoe can be freely applied upon the jack or removed. The. swinging jack members 26 and 27 are locked in such normal position forward upon the lever 20 and must be released before the shoe upon the jack can be moved to bring its heel against the cutter.

A latch lug 28 is formed integral with and projects upwardly from the forward end of the lever 20. This lug 28 is engaged by a spring tensioned latch bolt 29 slidably mounted within a groove in the casing plate 30 secured upon the front face of the arched bearing plate 31 fixed to the rocking jack 27. The arched bearing plate 31 rides or slides upon a curved track plate 32 fixed upon the front end of the cradle 26. The

bearing plate 31 and track plate 32 support the forward end of the rocking jack and provide stops to limit the rocking motion of the rocking jack 27.

As will be seen from Fig. 5, lugs or washers are secured to each end of the bearing plate 31, which project from said plate sufficiently to alternately engage with the respective ends of the track plate 32. The lock bolt 29 is located central with the rocking jack 27 and thus serves to center the rocking jack upon its cradle 26 when the parts are in their normal position.

The lock bolt 29 has a pin 33 fixed thereto and projecting from each side thereof. The forward end of the pin 33 is engaged by a trip lever 34 pivotally mounted upon the forward face of the bearing plate 31 of the rocking jack 27 The rear end of the pin 33 is adapted to alternately engage into the notches 35, 36, (see Fig. 1), formed respectively in the bearing plate 31 and track plate 32 and provides the means for centrally connecting the rocking jack 27 and cradle 26 and locking jack 27 upon the cradle 26 against sidewise swing. The latch bolt is therefore utilized for locking the jack 2'? and its cradle 26 against forward and rearward swing upon the lever 20 and the rocking jack 27 against sidewise motion upon its cradle, and also serves to relatively center the parts. The'notches 35, 36, are located in their respective members at a point central with the jack and cradle and the notch 36 in the cradle is of a depth to permitsufiicient upward motion of the latch bolt 29 t unlatch the cradle from the lever 20 without unlocking the rocking jack. The cradle and jack can thus be swung rearward until the abutment 37 projecting from the cradle engages or rests upon the lever 20, when the parts are in position to be moved toward the cutter. A treadle 38, mounted at the base of the column, connects with the lever 20 through a link 39 for raising the lever 20.

After the heel breast has been trimmed, the shoe may be rocked to the right or left for trimming the edges of the heel and sole at the shank by moving the latch bolt 29 upwardly its limit of throw, disengaging the pin 33 from the notch 36 in the cradle and bringing the pin into registry with the notch 35 of the rocking jack. The jack and cradle must be brought into a relatively central position before the jack can be locked to the cradle which always insures bringing the parts to their proper position for trimming the heel breast.

Toe rest.

At the swivel end of the rocking jack, I provide an adjustable toe rest moving in a direction parallel to the axis of the pivot pin 40 connecting the rocking ack 27 to the cradle 26. The toe rest comprises a member 41 having a saw toothed rack extension 42 sliding within the guide plate 43. The guide plate 43 straddles and is fixed to the end of the rocking jack 27. The teeth of the rack extension 42 engage with the teeth of a rack plate 44 fixed to the ack 27 and an adjustment of the toe rest is made by raising or tilting it sufficiently to disengage the rack teeth of the rack member 42 from the teeth of the rack plate 44- and then sliding the toe into the nipple 48 integral with and projecting from thefree end of the-rocking jack 27. The nipple intermediately is notched to receive the nut 49 engaging the screw 47 for adjusting the head of the post to different elevations. '49 indicates a dowel pin fixed to the head and slidably fitting into a bore in the nipple 48. A jack pin block 50 is hingedly mounted upon the post head 46 having a pin 51 projecting therefrom, adapted to engage into a socket or bore in the shoe last. The pin block 50 has a lug extending at right angles therefrom, providing a movingzabut-ment for the spring 52 seating within a bore in the head 46. The spring. urges the pin block toward the head and provides a yielding coupling for con necting the shoe last-to the jack post, enablingthe lasted shoe to be swung to bring the toe of the shoe upon the toe rest and forcibly hold the toe of the shoe upon the rest.

H eel clamp.

Afterthe shoe has been mounted upon the jack post with its toe engaged upon the toe rest, the heel is engaged by a clamp which securely holds the shoe upon the jack. The setting of the clamp edge with relation to the breast edge of the heel governs the amount of material to be trimmed off of the heel'breast:' Thus'the clamp also qualifies as a gage whichenables the heels to be uniformly trimmed.

The clamp consists of a pair of rack arms 53, 53, one mounted and hinged upon each side of the forward end of the rocking jack 27. These arms 53 engage into ways formed in the clamp frame 54, adapting the frame to be moved longitudinally upon said arms. The clamp frame 54 supports and journals into the block from each side.

a pinion shaft 55 with the pinion teeth respectively meshing with the teeth of the rack arms 53, whereby when the shaft 55 is rotated the clamp frame may be moved upon the arms in either a heel clamping or releasing direction. A cover plate 56 forming a closure for the right rack arm 53 is secured to the clamp frame, and is provided, inte grally, with a cylindrical casing portion 57 which has ratchet teeth formed upon its inner periphery adapted to be engaged by a pawl 5S'pivotally mounted in the hub portion 59 of the clampinglever'60fixed upon the end of the pinion shaft 55. In practice for convenience of manufacture, the ratchet teeth are out upon the inner periphery of a ring which is fitted and secured within the annular flange of the casing 57.

The pawl 58 has a stud projected therefrom which has a bearing in the clamping lever, bringing the stud upon the exterior side of the clamping lever to which a pawl lever 61 is fixed. The pawl lever 61 extends ina direction parallel with the handle portion of the clamping lever 60 adapting the pawl to be released for freely rotating the pinion shaft in any direction when either releasing or clamping the heel. This clamping lever and its shaft can be adjusted so as to always bring the handle to a mostconvenient position for the operator, and which adjustment is made when the work is changed from one size of heel to another. The pawl locks the pinion shaft against motion in a clamp releasing direction, so that the clamp can be brought down upon the heel under any'desired pressure and retained in its clamping position. The left end of the pinion shaft 55 projects slightly beyond the clamp frame 54 to receive a spring 62 engaged between a washer, forming a head for the shaft, and the clamp frame for ur ing the shaft longitudinally and enabling the shaft to be slid toward the right for disengaging its pinions from the rack arms 53 for adjusting the position of the clamp lever 60. The clamp frame 54 is provided with'a handle 63 which is grasped by the operator for swinging the heel clamp over or away from the heel, and also for rocking thejack 27 sidewise in trimming the heel breast edges and shank portions of the shoe.

A 'jaw block 64 is mounted within the clamp frame 54 and pivotally secured to the frame by a pair of screws 65, one engaged The aw block 64 is provided with upwardly and laterally projecting arms 66 which lap over the ends of the clamp frame to receive the templet plates 67, 67. The templet plates each respectively engage with a screw 65 as a fulcrum for swinging the templet to adjustits position relatively to the jaw block. Each templet isprovided with a curved slot ne-fted,

68 through which a screw or pin 69 engages for securing the templet to an arm of the jaw block.

As shown, the templets are coupled together by a connecting rod 70 to insure uniform adjustment, one with the other. These templets are each provided with a cam or guiding edge l which governs the pitch of heel trim or vertical outline of the heel breast, which may be either straight or curved and also limit the amount of material to be trimmed off of the heel breast. The guiding edges 71 of the templets engage against rollers '72 sleeved upon the bearings of t is cutter shaft 3 and concentric with said shaft, thereby limiting the movement of the jack toward the cutter. In Fig. 9 a straight edge templet is shown, engaging a roller 72.

The jaw block 64 at its upper side is provided with a dove-tailed groove into which is slidably fitted the shank portion of a heel stop plate 73. This stop plate 73 is secured to a screw 74 threaded into the block 64 for adjusting the curved heel engaging portion 75 0:. the plate toward or from the front of the aw block.

As shown in F 9, the portion 75 of the heel stop plate l3 engages the rear of the heel and thus serves as a gage for properly setting the clamp and its templets so that no skill is required in producing uniformity in the work when trimming a lot of shoes of the size and style of heel. The lower face of the jaw block 64 is provided with a roughened or serrated plate for firmly gripping the lift of the heel when the shoe is clamped within the jack.

Emi ia-24st hood or snout.

71 indicates an exhaust hood or snout a ljustably secured to the rod or over arm iis snout has a rear tubular portion to which the exhaust conductor piping is cond from the tubular portion is developed into rectangular conduit portion, with its lower wall curved at its extremity, forming a guard'78 to partially shield the cutter, as shown in Fig. 9, and against which the sole of the shoe at the shank is brought to limit the upward motion of the jack, making it impossible to out into the sole at the shank. The snout is mounted upon a bracket 79 and is adjustable with said arm in a direction radially with. respect to the diameter of the cutter and also upon the arm in a direction toward and from the cutter. The bracket arm 79 is pro vided *ith a sleeve through which the over arm or rod 4 projects, and upon which the arms swing. The sleeve is split toward one end for frictionally clamping the arm to the rod 4. A screw 80 engages through ears projectin from the sleeve at its split portion pro ing clamping means.

A clevis or eye bolt 81 is pivotally mounted upon the frame of the machine with its bolt end engaging through the arm 79 and carries a nut 82 for adjusting the arm pivotally upon the rod to bring the guard 78 to its proper position about the cutter. The bolt also carries a spring 83 pressing against the lower face of the arm to urge the arm in an upward direction and assist in making an adjustment. The snout has a plane upper wall which bears against the lower face of the bracket arm, and is provided with a pair of lugs 84, 85, lug 84 projecting through a slot 86 in the arm 7 9 and carrying a set screw 86' for securely fastening the parts together. Lug carries a set screw 87 extending at right angles thereto and having a threaded engagement with a. threaded bore in the sleeve portion of bracket arm and provides for a micrometer adjustment of the snout in a direction toward or from the cutter. Thus an adjustment of the snout in one direction is made by adjusting the snout upon the bracket arm 79 by turning the screw 87 after which the parts are locked together by the set screw 86 and the second adjustment is made by the nut 82, to swing the bracket arm upon the over arm or rod 4.

Cutter guard.

In machines having a rapidly revolving cutter it is a requirement in many states and localities that said tools be protected with proper guards to prevent injury to the operator. To fulfil such requirement, I provide foldable guards comprising two curved ates 88, 89, hingedly connected together inde sn'ing tension and arranged to fold each other so as to automatically envelop the cutter, as shown in Fig. 4.

1e plate 88 has a pin 90 projected beyond both of its side edges, and the hinge yin 90 similarly projects laterally so that both pins engage and ride over the roller sleeves upon the cutter shaft bearing be tween which the cutter is disposed. The pins 9090 guide the plates around the cutter and free from contact with the cutter. The plate 89 is hingedly mounted between the sprin actuated levers 93 connected as a unit and pivoted to the bracket 21. These levers are engaged by a rod 91 projecting from the side of the cradle, so

that the guard is moved automatically with the motion of the cradle. The guard plates 88, 89 are arranges so that the pins 90-90 first travel around the roller sleeves and subsequently upon a rail 92 formed upon the lower face of the exhaust snout which guides the plates from and toward the cutter. (See Fig. 9.)

Mode of operation.

lVith the jack parts in their normal position as shown in Figs. 2 and 4, but with the the last or shoe.

crosswise of the heel will either follow at heel clamp swung rearward to rest upon the The shoe can be shifted, slightly moving the toe either to the right or left upon its rest,

so that the cutter will trim the heel breast at a proper angle relative to the swing of That is, the trimming right angles or at an obtuse angle to a line drawn from the center of the toe of the shoe to the heel and appropriately in the latter instance for a right or left shoe, in degrees to meet the fashion of the various manufacturers. With the shoe properly located within the jack the heel clamp is brought upward with the clamp jaw engaging over the heel to a limit permitted by the jaw heel stop, a proper adjustment of the stop having been made. The manner in which the various adjustments are made have been previously made clear when describing the parts, so that it is not necessary to again allude thereto.

It is therefore assumed that the lasted shoe has been properly positioned and clamped within the jack and ready for trimming the heel. The handle 63 is grasped with one hand by the operator and with the other hand the lever actuating the latch bolt is moved to release the bolt from its engagement with the lug upon the lever 20, and the jack members 26, 27 are swung to a reclined position upon said lever 20 This step in the operation is necessary, otherwise it would be impossible to swing the shoe beneath the cutter. Now with the aid of the treadle,the lever 20 and jack membersare swung upwardly, the jack members swinging upon said lever to engage the templet against the cutter bearing rollers. The operator applying pressure through his holdupon the handle 63, retains the templet engagementlwith the rollers during the con tinued upward movement of the jack while trimming the heel breast. The jack is moved upward until the shank of the shoe engages the guard at the end of the exhaust snout, which finishes the trimming operation unless the edges of the heel are to be roundedor trimmed. If such edge trimming is desired, the operator continues to hold the jack in its uppermost position and releases the rocking jack from the cradle and then rocks the jack to one side and then to the other side. holding the templet firmly against the guide rollers and the shank of the shoe against the stationary cutter guard of the exhaust snout. This side or rocking movement of the jack will trim the curved portion at the juncture of heel and sole toa' design-conforming to'the shape of the shank from edge to edge. After edge trimming or rounding, the ack is again brought to a central or ahnlng position with i the cradle and locked, treadle pressure is along a line which bears a relation to the plane of the heel face lift, automatically producing the finish much sought by shoe makers. Thus if the face lift of the heel is slightly inclined the heel breast trimming line from lift to shank will be at a different pitch than if the face lift follows a straight line. The heel breast pitch or its line of trim will always bear a relation to the line of trim of the rear portion of the heel which likewise is gaged by the line of the face lift; thus symmetry is produced between the various finish lines of the heel.

It will also be appreciated that an inr portant feature is the arrangement the jaw block 64, being pivoted so that as the same is brought into engagement with the toplift or face-lift of the heel, it automati-- cally adjusts itself to the plane of the heel, and exerts a uniform pressure on the entire heel automatically. This arrangement also avoids straining either the heel or the shoe, as would be the case if the clamping frame 54- and jaw block were solidly and rigidly connected so as always to effect a clamping a tion on a fixed plane.
