Application led April 7, 1913. SeriakNo. 759,421..
To all whom t may concern.'
Be it known that I, EUGENE L. KEYES, a
citizen of the United States, residing at/Bos? ton, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Trimming- Machines, of which the following description, 1n connection with the accompanying drawlngs, isa specification, like reference characters on the drawings indicating like parts 1n the several figures. i
vThis invention relates to -machines for trimming or shaping blanks formed'from sheet material, and one important Object 1s to eEect an improvement in that class of machines that operate to `scarf Or bevel the face of the blank, by providing means'to regulate the beveling operation so as to 1nsure a out of constant depth however the thickness'of the Work may vary.
In a more particular aspect the invention contemplates an improvement in machines that operate to trim the edges of the work and simultaneously to scarf or bevel the face of the work at the edges. Machines of this type usually include an edge trimming cutter and a second or beveling cutter. y,
.This invention, in a preferred embodiment, comprises means to effect lrelative ad-A justment of the work and the beveling cutter without disturbing the operative relation of the work to the edge trimming cutter, through the operation of a member that contacts with the work and is movable in proportion to variations in the thickness of the latter. The relative positions of the work and the beveling cutter will depend, therefore, upon the thickness of the blank, and that faceof thev work which is to be beveled will be presented constantly in the same position in relation -to the cutter through the operation of the contact member.
for varying at will the normal relation of the beveling means to the regulating means so as to change the depth of the bevel.
A further particular object off-'the invention is to provide means for beveling or scaring the face of a welt insole at the heel seat'after the insole has been attached to the last. In the manufacture of this type of shoe it is often found desirable to scarf the face of the insole at the edges of theheel seat so as to approximate the thickness of Specification-Of Letters Patent.
The invention contemplates also provision TnIMMING-MAOHINE.
Patented Mar. 9`, 1915.
the channeled portion of the insole edge, and thereby insure 4a. better lit for the counter and other portions of the upper when assembled upon the insole in the lasting operation. Since it is a common practice, however, to provide an insole that shall be some.- what longer than the last after the tempering and channeling Operations, and then af.
ter attachment of the insole to the last to trim ofi that portion which projects beyond' the last at the heel end, it is obvious that the scarng operation cannot well be performed prior to the operation of trimming ofi' the surplus projecting material. By this invention I have provided means whereby the vin means whereby both the operations referred to may be performed simultaneously -on a single machine, thereby eliminating the time and expense ofl a subsequent scarfing operation. At Vthe same time, the controlling features previously noted permit the. formation of a bevel of any depth desired,
thicknesses of work without further atten-I of a bevel of constant depth for different and after adjustment insure the formation tion on the part of the operator.
A further improvement in my prior ma.- chine which I contemplate as a feature of this invention resides in means for determining or limiting the movement of the last and its attached insole when presented to the action of the cutter. This feature comprises means suitably positioned to limit movement of the forepart of the last to ward the rear of the machine as the last is 'mounted to turn upon its support, whereby to insure suoli a movement of the last in consequenceof movement of the support when the sides of the heel seat near the shank are presented to the action of the cutter that trimming too far inward toward the shank and abruptly beginning or ending the trimming operation at definite, points near the shank, with consequent format-ion of ridges at the sides of the insole, are avoided. This is a feature of particular utility in cases where the insole is widerl than necessary at the shank portion or is unevenly placed upon the last so that portions project beyond the bottom of the last at the shank. j
Other features and objects ofthe invention will be noted inthe following detailed description and pointed out in the claims.
In the drawings, Figure 1 is a view in elevation of a machine that comprises a preferred embodiment of the invention, portions ofthe frame of the machine being broken away. Fig. 2 is a section through portions of the cutters and the guiding and regulating means, showing also the operative positionl of the work. Fig. 3 is a detail view illustrating more clearly the operative relation of a last and insole to the guiding member and the cutters.
The frame 2 vof the machine supports a rotaryshaft 4 upon the forward end of which is secured `a rotary edge-trimming cutter 6. The cutter is held in place by means of an expansion bushing 8 and a plate 10 which is secured upon the end of the shaft by a screw'12 so as to maintain the bushing in expanded condition against the cutter. The plate 10 is circular in form and extends peripherally somewhat beyond the adjacent portions of the cutter teeth, thereby providing a guide that assists in maintaining the work in operative relation to the cutter. y
Pivotally supported upon a stationary bracket 14 so as to swing toward or away from the cutter in a plane substantially parallel tothe cutter shaft is a guide carrying head 16. This head may be swung up-v ward to afford access to' the cutter, but is secured in normal or operative position byv means of a plate 18 that slides through one side thereof and engages beneath the head of a bolt 20 that is threaded into a portion of the bracket 14.' The head 16 has'inclined guideways to receive a guide or abutment member 22 that has a guiding face or shoulder 24 and a lip 26 that projects slightly beyond said face along the inner edgev of the guide. It will be noted that the inner face of the member 22 is recessed to receive the plate 10 at the forward end of the cutter so thatfthe lip 26 is close to the periphery of the cutter. The member 22 may be ad'- justed radially of the cutter by means of an adjusting screw 28 that extends through a portion of the head and is held from movement therethrough, but has threaded engagement with the guide member. The pre-l ferred embodiment illustrated comprises a machine kfor operating upon the heel por tion of a Goodyear welt insole after the lat- -ter has beeny attached to the last, and the face 24 provides means upon which to position the side surfaces of the last, while the lip 26, projecting between the tread face of the last and the insole, serves to position the last axially of the cutter and provides an i abutment or rest for the under side of the therefore the depth of operation of the cut.
ter with respect to the last.
In order to hold the insole firmly during the cutting operation, a presser member 30 is arranged t'o contact yieldably with the outer face of the work close to the periphery of the cutter. The member 30 is formed with a `straight portion that is arranged to slide in a guideway 32 formedbetween adjacent faces of a portion of the head 16 and a plate 34secured thereto. The guideway 32 is inclined in al' direction substantially parallel to the periphery of the cutter 6. The presser member .is urged toward the work by a spring 36 and a plunger 38 that operate in a socket formed in a portion of the head 16, the plungerl bearing yagainst the rear side of the presser member. The ex tent of forward movement of the presser member is limited and may be varied by means of an adjusting screw 40l threaded through an'angular portion of the member at the rear of the guideway, the end of said screw bearing against the head.
As a means for scarngvor beveling the face of the work simultaneously with the trimming operation I have provided a second or beveling cutter 42 concentric with the cutter 6 and connectedv by means of a bayonet joint to a sleeve 44 which is mounted upon the shaft so as to be axially adjustable thereon. Thefteeth of the cutter 42 are and providing means for supporting pivotally segment pieces 5 2 that are loosely seated inV an annular 4recess in the periphery of the sleeve.` The arm 4S has lalst?) a. projecting portion 54 that extends to a point opposite the rear end of an extension 56 of the plunger 38 and is provided with an adjusting screw 58 that bearsupon the vend of the extension 56.
. With the mechanism described it will be obvious that there is a dependent operative relationbetween the position of the bevel-v ing cutter 42 and the position of the presser member 30. yBoth the cutter and the presser member are urged toward their limits of movement in the direction of the work and the lip or abutment 26, and the extent of movement permitted the beveling cutter in this direction depends upon the position of the member 30, the operative position of which dependsin-turn upon the thicknessl of the work interposed between said meinmember in the direction of. the abutment26` j serves to vary to the same extent the limit of movement of the cutter 42 in the direction of the abutment, while adjustment of the screwr 58 varies relatively the respective limits of movement of the cutter and the presser member and thereby serves to vary the normal depth of tliebeveh lt lwill be clear that the scarting or beveling mechanism may be readily attached to or detaclied'from the machineand that it may be used or not as desired without afecting the operation of the machine as an edge 6 may then be replaced and the head 16 se-A cured in position, when the machine will operate solely as an edge trimming cutter. 3y a reversal of the above o erations the attachment may be applied totthe machine. While it is possible to operate upon insoles satisfactorily on a machine constructed as above described, I find that both time and skill on the part of the operator are saved by providing the machine with a support for the last. The support preferably comprises a bracket arm 60 projecting from the frame 2, a. block 62 pivotally mounted on the bracket 60 so as to swing in a substantially vertical plane to the extent permitted by a stop member 64 on the bracket, and an arm 66 pivotally mounted on the block 62 so as to swing in planes substantially at right angles to the plane of movement of the latter, the extent of movement being limited by a projection on the arm that engages in a recess 68 in the face of the block 62.v The arm 66 may thus have a subc stantially universal movement. The arm carries at its upper end a last supporting pin 70 -held loosely lin a socket in the arm by means of a smaller pin 72, the mounting be-v ing such that the pin 7 0 may wabble in its socket, particularly in a direction-transverse yto the arm 66. A A j In the operationof the machine with the mechanism thus farv described the workman slides upon the pin 70 a last having an insole attached thereto, and swings the last and support toward the cutters, guiding the last so that the lip-26 will be inserted l between .the insole and the last bottom and the portion of theside of the last close to the tread face will bear against the shoulder 24, 'thus inserting the insole between the lip oruabutment 26 and the member 30, which cooperate as presser membersto hold the work 1n position for the action of the cutters. As the insole is inserted in the manner describedpthe member 30 will yield to an extent dependingl upon the thickness of the insole, and will thereby adjust the cutter 42 to form a bevel of the predetermined depth dependingV upon the previous adjustlment of the screw 58. In starting the cutting operation, the forepart of the last usually is raised to bring one side of the heel seat first into contact with the cutters, and the last 1s then swung forwardly and downwardly to present all portions of the edge of the heel seat to the action of the cutters. The mounting of the arm 66 and the pin 70 on the arm permit the movements of the last necessary to trim all parts of the insole that project at the sides of the heel as well as at the heel end, and to keep that portion of the side of the last that is directly adjacent to the tread face in contact with the shoulder 24, which is shaped to engage this portion and therefore to guide the sole with reference to the edge ofthe tread face. It
is usuallypreferable to trim the edge of the i insole so that the trimmed edge will lie flush with the lateral faces of the last. Consequently the guide member 22 should be suitably adjusted, as shown in Fig. 3, so that the edge 0f the sole when trimmed shall form practically a continuation of the contour of the vside faces of the last. During the trimming operation the presser member 30 obviously will move in proportion to variations in the thickness of the insole, and will vary to the same extent the position ofthe cutter 42 so as to maintain a bevel of constant depth.
I have found that it is/ desirable to provide in a trimming machine of the type described further means to limit and determine the movement of the last when the insole is 'presented to the action of the cutter.
An insole will frequently be wider than trimmed edge to merge gradually with the untrimmed edge at the shank. In the illustrated preferred embodiment these stops comprise projections '7 4 and 76 on a plate `7 8 that is adjustably mounted by a screw and slot connection on the face of the head 16 closely adjacent to the guide member 22. The member 22 and the plate 78 are so related as to be adjustable in paths that are substantially parallel. 1The stops 74 and 76 are thus in position to contact with the last on either side and limit the rearward movement of the orepart thereof When the last is mounted for turning movement upon the pin 70. If the workman beginsthe trimming on one side and ends it on the other side, as is usual, he -will first bring the forepart of the last into contact with the stop 74 and then swing the heel portion together with the support in toward the cutter until the last contacts with the shoulder 24, thus giving the edge of the sole a slight longitudinal movement as it is brought into contact with the cutter. Similarly, at the completion of the trimming o eration the last will Contact with `the stop 76 on -the other side and cause 'the heel portion and support to swing-away from the guide, thus withdrawing the sole edge from the action of the cutter while imparting thereto a slight movement longitudinally of its axis. The Workman' may, ofcourse, begin the trimming operation at the rear of the heel and turn the last alternately in opposite directions until it contacts with the stops. The result in either case is to merge the trimmed edges `gradually with the untrimmed portions. The plate 78, it will be understood, should be adjusted proportionally to the guide vmember 22, and it may be adjusted with rev spect thereto to' vary the extent of the trimming operation.
N Vhile I have described my invention as embodied in a machine of specific construcv tion it will be understood that this is merely for illustrative purposes and that the in` vention is susceptible of various other embodiments Within the spirit and scope of the appended claims. It should also be understood that while` I have employed frequently the term beveling in referring to the operation on the face of the insole, the invention is not limited to a cut of any particular character and the termsused are to be construed broadly as referring to any form `of cut that satisfies the purpose in View.
