UNITED STATES PATENT OFF-ICE.

FREDERIC E. BERTRAND, OF LYNN, MASSACHUSETTS, ASSIGNOR, '.BY MESNE ASSIGN- MENTS, TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY,`

A CORPORATION 0F NEW JERSEY.

SOLE-FITTING MACHINE.

To all whom it may concern Be it known that I, FREDERIC E. BERTRAND, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Sole-Fitting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to machines for operating 'on shoe soles and like articles, and

more specifically to sole channeling machines of the general type shown in my prior patents, such for instance, as Patent No. 1,030,- 701i, granted J une 25, 1912.

Machines of this character are designed to perform certain operations on a sole blank,

generally termed sole fitting, necessary to prepare it for attachment to the upperof a shoe, and the present invention has for its general object to improve the machines of this type. Stated more specifically, .the invention aims to increase the life of machines of this type and to relieve the operative of some of the care and attention which is now required of him in using the machines now on the market.

To these ends the invention resides in 'certain novel combinations and arrangements of parts, the advantages of which will be obvious to those skilled in this art, and the various features of which will be readily understoodffrom the following description, reference being made to the accompanying drawings, in which;

Figurel is a view, in side elevation, of an insole channeling machine including mechanism embodying the invention in its preferred form g` Fig. 2 is a horizontal, sectional view on approximately the plane indicated by the line 2 2, Fig. 1; and

F ig. 8 is a front elevation of certainof the parts shown` in Fig. 1 which relate to the present invention, ,this View being largely diagrammatic and omitting the adjacent parts of the machine.

In the embodiment of the invention illustrated in the drawings the machine is provided with a work supporting table 2 on which the sole S (Fig. 3) is positioned for Specification of Letters Patent.

Serial No. 83,253.

No. 1,028,801, dated April 23, 1912, by means.

of which it may be lowered to permit the insertion or removal of the sole. Tools of any character suited to the requirements of the operations to be performed on the sole are mounted in suitable position in the machine head, and include a channeling knife 4l. Since the particular tools employed, and the operating mechanisms for them, form no part of the present invention, they will not be specifically described' herein, but reference should be made to my prior patents hereinbefore referred to for a detailed description thereof.

The sole fitting tools are operated through mechanism that is supported by the frame 1() `and which includes a driving mechanism comprising a shaft 12 rotatably mounted in suitable bearings carried by the frame 10, a loose pulley 14 rotatable on said shaft and constituting the driving member for the machine, and a clutch member 16 Vwhich is keyed to the shaft 12 but is slidable along the shaft into and out of Vengagement with a clutch face formed on the pulley 111.y A coiled spring 18, encircling the hub of the clutch member 16 urges this member toward the pulley. It is obvious that when the clutch member 16 is out of engagement with the pulley 14 the machine will be rendered inoperative, but when the members 14 and 16 are engaged, the driving mechanism then becomes operative to rotate the shaft 12 and operate the tool or tools with which the machine is equipped. I

The clutch mechanism just described, and consequently the driving mechanism, is'under the control of a mechanism which includes feeler that engages the 1sole when it is positioned on the table 2 in readiness for the tools to operate it. This clutch controlling mechanism includes a reversed or inverted toggle Vmechanism which is duplicated at each side of the machine. Two parallel toggle arms or links 20 are mounted on opposite sides of the frame 10 (see Fig. 2) and are both pivotally connected at their rear ends to a shoe 22 that is located' in a periph- 'in the shoe.

lend to one of the lever arms 20, acts through the toggle links 20 and 24 in a direction tending to break the toggle and, consequently, to slide the `clutch member 16 toward the pulley 14. This spi-ing thus aids the coiled spring 18.

In order to straighten the toggle and thus move the clutch member 16 away from the pulley 14, a power driven mechanism is provided which isbest shown in Fig. 3. This mechanism consists of an eccentric 32, fast on the shaft 12 and therefore constantly driven while they machine is inv operation; an eccentric strap 34 arranged to be oscil* lated by said eccentric; a bell crank lever 36 fulcrumed on the machine frame at 38 and having one arm pivoted to said eccen.-

tric strap; and a link 40rpivoted to the op- Y posite arm of said bell crank lever. The freeV end of this link 40 is connected by another link 42 to the free end of an arm 44 vdepending from a vrock shaft 46 fulcruined toggle link 24,'and this engagement is controlled bya depending feeler 52 which is positioned vertically over the table 2 and is supported for movement normal to the table by two parallel links 47 and V56. The

' link47 is fixed on the rock shaft 46 while the link 56 is pivoted'to the machine frame. It will now be clear from an inspection of Fig. 3 that, when the machine is in opera- Vis removed from'under the feeler'52, thisfeeler dropsunderthe influence of gravity toward theV table 2 (see'Fig. 1)', Vthus swing-Y ingthe lower end of the arm 44in`a contraV clockwise directionand causing the hook 48, on its next upward movement, to slide over the Vupper edge. Vof thelug 50 and to carry this lug downwardly on its next downward stroke. This action moves the toggle 20n-f24 from vthe broken position in which it is shown in dotted lines in Fig. 111 into straightened position, as indicated in full lines in said figure, thus overcoming the ac# tion of the springs 30V and 18 and sliding of engagement with the-pulley 114.' This .action, of course, disconnects the shaft from the driving pulley 14 and interrupts the op-V eration of the driving mechanism.

The table 2 is depressedto remove the sole from it and to place another sole in position thereon, and when this table next rises, carrying a new sole up under the lower end of the feeler 52, this member israised and operates through the arms 47 and 44 and the link 42 to move the hook48'out of engagement with the lug 570. andfthus permits the spring 30 to break the toggle again, and consequently to move the clutch memthe clutch member 16 along the shaft 12 out j ber 16 into engagement with lthe pulley 14 l u and start the machine into operation. The machine, of course, will continue in operation until the work is removed from engage Y ment with the feeler again, whenrthe cycle of operations to stop the machine willA be re-V peated. A Y Y A brake is provided for the purpose of stopping the machine quickly when .the

face with which a correspondingly shaped face'on the end'of the clutch inember`16,VY i

opposite to that which engages vthe pulley 14, is adapted to engage. This brake is mounted immediately in front of the clutch so that it is engaged by the clutch member 16 immediately said memberris freed from the driving pulley 14. Since theV clutch member 16 ,is keyed to the shaft 12,.its engagement with the brake rapidly retards and practically instantaneously stops theV rotation of the shaft 12. Inasmuch as'the clutch member 16 is under the control of the feeler 52, the positionof this feeler deter.- mines whether the driving member 14 'or the brake 60 shall .be operatively connectedV to the shaft 12 at any instant.V

It is obvious that the mechanism above described renders the startingV and stopping of the machine entirely automatic andY dependent Ymerely upon thefpresentation of Y the work to the tools ofthe machine. The

operative thus-is relieved of the careV and attention which otherwise wouldfberequired Y f of him to start and stop. the machine., At

the same time the useless wearVv on the'run-V Q ning parts ofthe machinegwhich otherwise A would be occasioned by the idle ruiming ofY the machine is eliminated andthe life'of'theY machine is correspondingly increased.

While the embodiment of the invention at present preferred has been described above for the purpose of clearly explaining the nature of the invention, it is obvious that the invention is not limited to embodiment in the specific form shown, but that it may take many forms without departing from its scope as defined in the appended claims. It will also be understood that the invention is not limited in application to the spey cie type of machine shown.
