LNITED STATES PATENT UFFICE JAMES B. DOBYNE, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE LANDIS VAX THREAD SEWING MACHINE COMPANY, OF SAME PLACE.
THREAD-WAXING DEVICE FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 613,126, dated October 25, 1898.
Application filed May 1d, I895. Serial No. 549,366. (No model.)
To all whom it may concern:
Be it known that I, JAMES B. DOBYNE, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Wax- Thread Sewing-Machines; and Idoherebydeclare the following to be a full, clear, and exa-ct description of the invent-ion, such as will enableothers skilled in the art to which it appertains to make and use the same.
The object of this invention is to provide an improved waxin g attachment for that class of sewing-machines that are more especially used in the manufacture of harness and leather goods generally.
In the drawings, Figure 1 is a side elevation of a sewing-machine embodying my improved features; Fig. 2, a vertical transverse section on line 2, Fig. 1, looking iuthe direction indicated by the arrow, some of the parts being shown in elevation; Fig. 3, a plan section on line 3, Fig. 2; Fig. 4, a vertical section on line t, Fig. 3; Fig. 5, a vertical section on line 5, Fig. 3; Fig. 6, a plan of the wax-reservoirand heatingtank; Fig. 7, a vertical section on line 7, Fig. 6; and Fig. 8, a broken-out section on line 8, Fig. 6.
A represents the supporting-base; A, the
stationary overhanging arm, that is usually cast integral with the base part; A the needle-lever; A the needle-bar; A the needle; A a combined needle-cam and fly-wheel, and B the driving-shaft.
In the supportingbase under the head B of the overhanging arm is located a closed heating-tank B in which is seated a wax-reservoir B opening above the same, as shown in Figs. 2, 6, and 7. This tank is secured in place by a number of tap-bolts a.
In one end of the wax-reservoir is a pumpcylinder C and plunger C, adapted to have a reciprocating movement therein through the media of the following mechanism.
A rocking pump-lever C Fig. 1, is pivoted near its longitudinal center to the base, as at a. The inner end of this lever bears upon the upper end of the pump-plunger. To the outer or opposite end and under side of this lever is attached one end of a spring 0 the other end of which is supported from the rear part of the base. The upper end of the plunger is provided with opening (1 extending horizontally therethrough. In this opening is loosely inserted one end of a spring-arm C the other end being secured to the front part of the base, as shown at c A cam projection a is mounted on the driving-shaft and is adapted to have an intermittent contact with the rear end of the pumplever and depress the same against the pressure of spring C once in each revolution of the drivingshai't. \Vhen the cam depresses the lever, the spring C raises the plunger, and as the cam passes on out of contact the spring C throws that end of the lever up and the other or front end down, thus imparting an automatic reciprocating action to the pump-plunger coincident with that of the movement of the machine proper.
The lower end of a tube D is tapped into the raised portion 1) of the inside bottom of the wax-reservoir. An adjustable wax cup or sleeve D is telescopically mounted on the upper end of tube D in the pathway of the needle. This waxcnp is provided with a laterally-projecting lug Z), Figs. 2, 5, and 6, with which the lower end of an adj usting-stud b has a threaded engagement. The upper threaded part of this stud-bolt has an adj usting-nut b threaded thereon. This not is provided integrally with an annular grooved base I), engaging with the edge of a plate 19", secured to the top of the wax-reservoir. A slot (1, Fig. 6, starting in from the inner edge of plate 11 provides for the slipping in of the stud-bolt to its place. Turning the nut 19 has the effect of running the stud up or down the Well-chamber d through a port d, which is momentarily uncovered-when the plunger is in its highest position. On the downstroke the plunger closes the port and forces the charge of wax through passage d and tube D up into the Wax-cup, the overflow returning down the outside of the same into the reservoir again. A ball-valve d is loosely seated in the upper part of tubeD and closes the passage therethrough against a backflow when the plunger is on the upstroke.
A gauze strainerd in the wax-cup prevents bits of leather and other foreign matter from getting to and interfering with the working of the ball-valve and clogging the passage communicating with the pump.
The Wax may be kept in a fluid state by a body of water in the tank, as shown, which may be heated by gas or other suitable appliance. A gas-burner pipe is indicated in dotted lines. Steam or electricity may also be used as a heating agent. By this arrangement a continuous and uniform flow of the wax is maintained and the same kept in a fluid state at an even temperature.
When a body of heated water is used to keep the wax in a fluid state, the tank is provided with a safety-valve attachment, Fig. 8, consisting of a chambered screw-plug g, inserted in the tank and opening therein, a ballvalve g, seated in the chamber g and an escape-pipe g Ordinarily the water in the tank will be kept below the boiling-point, but should it reach a temperature sufficient to generate steam the pressure will raise the ball and allow the steam to escape.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In a wax-thread sewing-machine, the combination of a wax-reservoir, a heating device, for keeping the wax in a fluid condition,
. a pump-cylinder communicating with the heated wax chamber, a plunger Working therein, a rocking lever, pivoted to the base of the machine and having one end bearing on the upper end of said plunger, the drivingshaft, mounting a cam which is adapted to have an intermittent contact with and depress the outer end of said lever, means, for raising said lever when the cam has passed out of contact, and means for raising said plunger when the pressure of the lever thereon is relaXed, substantially as described.
2. In a wax-thread sewing-machine, a pump attachment, comprising a well cylinder, a plunger, a rocking or. working lever, pivoted to the base of the machine, a cam, mounted on the driving-shaft and adapted to have contact with and depress the outer end of said lever once in each revolution, a spring, adapted to force the lever upwardly when the cam passes out of contact, and a spring outside the well and connected with and raising the pump-plunger when the inner end of the lever has been raised out of contact therewith by the cam acting on the opposite end thereof, substantially as described.
3. In a pump attachment for wax-thread sewing-machines, the combination of a pumpplunger, having an opening through the up per end thereof, a spring-arm, secured to the base part of the machine and having its loose end inserted through said opening, arocking lever, pivoted near its longitudinal centerto the base, the inner end bearing on said plunger, a spring, connected to the outer end of said lever, and the driving-shaft, having a cam mounted thereon which is adapted to have an intermittent contact with and depress the spring-pressed end of said lever, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
JAMES B. DOBYNE.
