Patented 1-. 25, 1913.
Application filed July 29, 1909. Serial No. 510,234.
tion with the accompanying drawings, is a specification, like reference characters on-the drawings indicating like parts in the several figures.
This inventionrelates to trimming niachines and particularly to trimming ma chines of the type commonly employed in the manufacture of boots and shoes in which the trin'nningoperation is performed by a rapidly rotating cutter. I
According to the usual'practice of man ofacturing shoes, the shoe is sent to the operator to be trimmed with the sole already having substantially the shape desired in the finished shoe. .The sole edge, however, it still rough and uneven, and before the shoe is finished the edge must be trimmed, inked and burnished.- Inthe trimming operation, according to-the; present practice, the operator or trimmer holds the shoe with the sole edge against a rapidly -revol ring cutter and draws it past the cutter, guiding the shoe by his eye in such a man-- ncr as to maintain substantially its existing contour. To guide the shoe so' asto produce a sole of correct shape with a smooth, even edge surface, and at the same time .avoid trimming too closely to the stitches, articularly in trimming shoes having poi ted toes, requires a high degree of skill and experience on the part of the operator.
The presentinvention aims broadly to facilitate the trimming operation, and more specifically, to provide an improved attachment, hereinafter termed a gage, for a'trimming machine by which the operator may regulate to a nieety the depth of cut of the tool; which shall positively limit the depth of cut during operation on certain portions of the workfwhich shall be capable of various adjustments, and which may be readily moved away from the cutter to permit in.- spcction or removal of the latter.
The particular manner in which the above objects are attained will be clear from the 'pin detailed description of a preferred embodiment of the invention hereinafter set forth.
Briefly stated, the invention in the embodiment illustrated in the accompanying drawings comprises an adjustably mounted frame carrying a stationary edge rest, a movable edge rest and a stop-controlling finger, each of the edge rests and the finger being arranged to engage the work, and an adjustable stop mounted on the finger and adapted to engage the movable edge rest and limit its motion during operation on certain portions of the work.
The invention also comprises other features of construction and operation and certain combinations and arrangements of parts \\'h1'Cl1 Wlll be hereinafter described and forwhich protection will be sought in the appended claims.
In the accompanying drawings, Figure l is a view in front elevation of the gage ap plied to a trimming machine. Fig. 2 shows in front elevation the positions of certain parts of the gage as the cutter operates along the side of the sole. Fig. 3 is a view similar to Fig. 2 showing the cutter trimming around the toe portion of the sole. Fig. 4 is a perspective view of a' detail later to be referred to. "Fig. 5is a view in side elevation of the parts supporting the stationary edge rest.
The gage mechanism is supported by a pin 2 projecting from the standard of the trimming machine, on which pin is adjustably mounted a gage-carrying head 4 having a set screw 6 for holding the head in an adjusted position. By turning the head on the pin 2 the entire gage mechanism may be swung away from the cutter to permit removal of the latter; and the head is retained in either its operative or inoperative position by two spring pressed plungers mounted in the head, one of which is shown at 8, Fig. 4, and which snap into suitable recesses in the standard of the machine. The turning movement of the head 4- relatively to the 2vis limited by stop pins 10 and 12 carried respectively by the head and standard. The head is provided with a slideway 14, as shown in Fig. 4, in which is received a frame 16 that supports the remaining members of the gage. The frame consists of a casting and a plate 18 secured thereto by screws 20.
he frame may be adjusted toward and from the cutter in a plane transverse to the shaft of the latter by means of a short lever 22 fulcrmned on a post :24 rigidly fixed in the hub 4 and extending through a slot in the frame. A pin 26 projecting from the frame is positioned in an aperture in the handle and by moving the right hand end of the lever. as seen in Fig. 1, up or down. the pin and consequently the frame Itwill be moved in the slideway 14. \Vhcn the desired adjust-intent has been made the frame may be locked in its adjusted position by a thumb nut 28.
A projection 30 extends to oneside of the frame 16 and drilled to receive a pin having a transverse aperture in which the upper end of the stationary edge rest. 34 is adjustably secured. A helical spring 36, see Fig.- 5. positioned between the projection 30 and an arm 38 rigidly mounted on the pin 32. holds the pin in its forward position and serves to prevent the edge rest 34: from sliding through the pin 32 after it has been adjusted therein. The edge rest 34 normally occupies the position in which it is shown in full. lines in Fig. 1. but may be swung into the position indicated by the dotted lines when it is desired to remove the cutter as above mentioned. In order to adjust the i-est with relation to the cutter, a screw l0 is threaded through the arm 38 and abutsagainst a stop 1L2 on the frame-plate 18 and a lock nut i4 holds the screw in an adjusted position. A second edge rest 46 preferably of segmental form is positioned at the side of the cutter opposite from the stationary rest 3% and is secured to the frame bv an extension 47, which for convenience in manufacturing is formed integral with the edge rest. and a pivot pin 48 positioned in alinement with the axis of the cutter shaft. A spring 50, connected at one end to the extension 47 and at its other end to a stationarv arm 52 adjustably. secured to the frame 16 by a screw 54, yieldingly holds the rest 46 in its forward osition. The movement of the rest i6 on its pivot is limited by a pin 49 which strikes the frame-plate 18. Located adjacent the edge rest 46 is a stopcontrolling finger 5G pivoted to the frame at 58, and also yieldingly held in its forward position by a spring secured to the stationary adjustable arm (32. A stop 64: is ad justably mounted on the finger 5G and said stop and finger constitute a locking device for the edge rest 46. the stop being arranged to engage the yielding edge rest 46 during operation on certain portions of the work to limit the mo ement of the latter. The point of engagement of the stop 04. with the rest i lmay be aried by a insting the stop (t on the tingt r 5 3 and also by varying the effective length of the finger itself. which is made extensible by the screw and slot construction shown at- 66.
During operation, the trimmer" take? the 'shoe in both hands and, starting at the shank, draws the sole edge across the cutter from left to right so as to ta he ll a thin shaving. The edge rests materially aid the operator in accurately guiding the shoe to regulate the depth of cut of the tor-l: the edge rest- 34 forming a fixed abutment on which the sole edge may be rocked to bring the sole nearer to or farther from the cutter. The finger 56 and edge 1' :t 46 each engage the sole and yield as the s we is manipulated during the trimming of the side of the sole. Fig. 2 indicates the position of he edge rests and finger during this operation. A the cutter approaches the toe portion of the ole the rest 16 and finger f-t'i each move forwardly. as they contznne to engage the sole. and as the pivots 4S and 55. about which respectively the rest and finger rotate. are widely separated, the path of movement of the stop (54 intersects the path of the rest .46.
-Conset' uentiy. the stop (3-1 will drop in behind the edge rest when the latter has moved forward to a certain point and thus limits the extent to which the sole edge can thereafter be crowded in between the ends of the edge rests'34 and 4G, and hence limits the depth of cut of the tool. In the position of the parts shown in Fig. 3, the edge rest is locked by the stop G-t and pin 4.) against movement in either direction. The time in the relative movement of the edge rest 40 and finger at which the locking action takes place may be varied by adjusting the position of the stops (Hon the finger and also by varying the effective length of the finger itself by means of the adjustable connections (36; and by means of these adjustments the depth of cut of the tool may be con-- trolled. As the shoe is further turned to allow the cutter to travel along on to the side of the sole again, the linger as will be forced backwart'luntil the stop (54 is swung clear of the yielding edge rest when the parts will again occupy substantially the positions in whieh they appear in Fig. 2.
To permit inspection or removal of the cutter it is merely necessary to swing the rest 34 from the full line to the dotted line position, Fig. 1, and then turn the g.-tge%rarrp= in'g head at in a counter-clockwise directi n on the pivot 2 until the gage parts are clear of the. cutter.
