Specification of Letters Patent. I s Patented, Oct. 14:, 1919.
Application filed January 14, 1918. Serial No. 211,852.
Be it known that I, FREDERICK M. FURBER, a citizen of the UnitedStates, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain new 'and useful Improvements in Methods and Apparatus for forking on Shoe-Stock; and
I do hereby declare the followingto 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 same.
This invention relates to a methodof and apparatus for eliminating the dust which accumulates at the operating point in certain forms of shoe machinery when operating on dust producing material.
Inthe manufacture of welted'shoes it is customary to trim ofi the projecting'edges of the vamp and lining after "the shoe has been lastedso that the instrumentalities of the welt sewing machine, articularly the looper, may not subsequent y be interfered with. This trimming operation is performed on a vamp trimming machine having a reciprocating-trimmer lmife cooperating with a rotatin shearing knife and guide roll, between w 'ch and the trimmer knife the shoe is placed to. be operated upon, In such a machine, as the shoe is pressed against the guide-roll, it is fed along and the cutting operation takes place progressively as the shoe feeds. fully illustrated in No. 922,697. V
In the manufacture of certain shoes it is customary to use j a box-toe material 1 of burlap which is permeated with rosi'nfjand it has been found, in trimming the vamp and lining of a shoe in which such material is used, a cloud of rosin dust comes from the machine, covering both the work and the the patent to Hadaway,
operator, and also tending to c'logthe machine. r
It is, accordingly, the object of th1s invention to I devise a method of eliminating the dust which accumulates at the operating point. in a vamp trimming or other shoe working machine "when working n dust producing material, and toprovide an apparatus for carrying out such method; With this object in view, the invention contemplates the'provision of means forapplying at-Orin proximity i to the working'point a detailed description 3 and Such a trimmingmachine is point.
jet of substantially dry steam to carryjaway or lay the dust formed by the Working tools.
While the improved method and appara' tus for ca'rrying'it out is particularly applicable to a vamp trimming machine, and has, for convenience, been shown and described asembodied in such a machine, it
will be understood that it is not limited in its application to such a, machine but may be embodied in various other shoe working machines. I
WVhen this invention is employed in a vamp trimming machine the steam jet forms prevent the accumulationthereon of dust or dlrt durlng the operation of the machine.
Within the scopeof the present invention to deliver a jet of substantially dry steam in close proximity to the working tools ofsuch a machine as an edge trimming machine to a thin film of moisture on the working tools of such machine to lubricate the tools and It will be understood, therefore, that itfis A form a film of moisture on and lubricate such tools to prevent the accumulation thereon of dirt and grease when operating on oily or sticky materials such as viscolized leather. The features of the present invention will be clearly understood from the following vation of a vampi trimmingmachine embodying this invention. Fig. 2 is a planaccompanying view with. parts partly broken, away and shown in section, showing the action of the trimming mechanism on the shoe and means for applying steam at the trimming Fig. 3 is a sectional view of the condensing chamber taken on the line 3 3 of Fig. l and looking in theldirection of the arrow. F ig. 4 is a sectional view looking from the sideof the machine on a plane passing through the vertical shaft of the guiding. roll, aportion of the frame being broken away. 7 Y
I In the vamp trimming machine shown in the drawings a standard 1 has projecting.
forwardly and toward theoperator therefrom an overhanging head 2. A, guide-roll 3, which engages the lining and directs the vamp and lining between the trimming knives, is arranged with its lower end directed downwardly so asto engage the sole of the shoe placed in the machine. Y The roll is secured to the'lower' end of a verticalshaft 41, which is constantly driven from the main operating shaft 5 by a belt 6 passing over a pulley 7 secured to a shaft 8 having fixed thereon a worm 9 engaging a worm.- wheel 10 secured to the shaft 4. The roll 3 is thus constantly rotated and feeds the shoe along for successive operations of the trimming knife as the shoeis held against said roll by the operator.
The trimming knife which cooperates with the roll to trim the vamp and lining is indicated at 11. The blade of the knife is curved in the arc of a circle and is secured by means of a bolt 12 to a knife carrier 13. This knife carrier is pivotally mounted and during the operation of the machine a rapid vibrating movement is imparted to the knife carrier by driving connection with the mainshaft 5, such connection not being part of this invention and not being illus trated herein. To guide said trimming knife in its vibrating stroke there is provided a knife-guide 14: secured to the frame of the machine by clamping screw 15 which passes through a slot in the knife-guide.
Cooperating with said trimming knife is a vamp bending device and knifeguard, which is indicated at 16, and, as shown, consists of a curved leaf-spring provided at its free end with an up-turned portion 17 and a laterally extending portion 18, said devices acting to bend a vamp into position to be trimmed and as a guard for the vibrating knife, in a manner more fully set forth in the aforesaid patent. The other end 19 of the said leaf-spring is bent downwardly and is provided with a slot, through which passes a clamping screw 20 by means of which the spring is secured to an oscillating carrier 21. During the operation of the machine a rapid vibrating movement similar to that of thetrimming knife is imparted to the vamp bending device by means of an eccentric on the main shaft 5, and a link pivotally connected to an up-standing arm of the carrier 21. The above described mechanism forms no part of this invention, all of which mechanism being old in the aforesaid patent, but has been briefl .described herein so that those skilled in the art may better understand the present invention, which, in the embodiment herein illustrated, is associated with such mechanism.
In such a machine as described above, the trimming knife 11 vibrates back and forth across the upper surface of the guiding roll 3 and successively cuts through portions of the shoe materials as the shoe is fed. If the shoe materials include material permeated with rosin or similar substance the action of the rapidly vibrating trimming knife and vamp bending device tends to produce an objectionable dust, which is deposited over the machine, tending to clog it and otherwise interfering with the operator. This invention contemplates the pro vision of means for applying a jet of substantially dry steam in proximity to the trimming point to carry away or lay the dust formed. during the trimming operation.
To this end, steam is passed under pres sure from a suitable steam supply through a supply pipe 22 having a valve 23, by means of which the flow of steam may be controlled. The steam passes into a condensing chamber 24 through an inlet 25, surplus moisture being precipitated by the action of the condensing apparatus and collecting at the bottom of the condensing chamber. When the water so precipitated, as a result of the condensation, rises to a certain height within the condensing chamber it acts upon a float 26 within said chamber, mounted to have sliding movement on a vertical rod 27 screwed into the upper part of said condensing chamber. The float 26 in its nor mal position is in the lower part of the condensing chamber, in which position it acts to close a drainage outlet 28, but when the water within the chamber reaches a cer tain level the float, because of its buoyancy, is raised, thus allowing the water collected in the chamber to pass out through the outlet 28. Steam, having been dried in the condensing apparatus, passes out through the outlet 29 and pipe 30, and is delivered at a point adjacent the point of cooperation of the trimming knives, as clearly shown in Figs. 2 and 3. The condenser is secured to the standard 1 by means of a clamp 31 and has a detachable head 32 secured to the condensing chamber by bolts and nuts as shown in Fig. 2. The washer 33, of suitable packing material, is placed between the two parts of the condenser, thus insuring a tight joint. The specific details of the condensing apparatus are immaterial to the present invention, and any suitable form of condenser might be employed.
The dust formed during the operation of the machine above described is precipitated and there is formed on the working tools a thin fihn of moisture to lubricate the tools during their operation, but the materials being worked on are not affected to any ma terial extent.
,Having explained the nature and object of my invention and specifically described one embodiment thereof, what I claim, is
1. That improvement in the method of working on shoe stock, including dust producing material, which consists in performing an operation progressively and applying a jet of substantially dry steam substantially at the working point and in such quantity as to prevent an accumulation of dust at that point.
2. The method of trimming upper materials of a shoe, including toe stiffening material, which consists in performing the trimming operation progressively and applying a jet of substantially dry steam substantially at the trimming point to carry off and lay the dust produced by the action of the trimming of the stiffening material.
3. That improvement in the method of trimming upper material Which includes material tending to produce dust When acted on by the trimming knife, accumulating on and interfering With the action of said knife, Which consists in operating the knife to preform the trimming operation and simultaneously directing against the knife ajet of substantially dry steam to prevent the objectionable accumulation of dust on the knife;
4. That improvement in the method of operating on shoe stock which consists in actuating tools to operate on said shoe stock and simultaneously applying in proximity Gopies of this patent may be obtained for to the tools a jet of substantially dry steam to form a film' of moisture on said tools to lubricate them. I
5. In a vamp trimming machine the combination of tWo cutting members, between which the work may be advanced to effect progressive trimming of the surplus upper materials around the shoe, means for oper ating said cutting members, and means ar-' ranged to deliver a jet of steam substantially at the cutting point.
6. In a machine forworking on shoe stock the combination of tools for operating on the stock, and means arranged to deliver a jet of steam substantially at the operating point of said tools and including a condenser for precipitating the excess moisture of the steam so that the steam is delivered in a substantially dry condition.
