JOHN S. HULL, OF BALTIMORE, MARYLAND.

CAN-SOLDERING MACHINE.

SPECIFICATION forming part of Letters Patent No. 404,195, dated May 28, 1889. Application filed March 26,1889. Serial No. 304,794. (No model.)

To all whom it may concern.-

Be it known thatl, JOHN S. HULL, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Can-Soldering Machines; and I do hereby declare the following to be a full, clear, and exact description part of this specification, Figure 1 represents a perspective view; Fig. 2, a vertical longitudinal section; Fig. 3, an "end View of the bracket for supporting the lower end of the can; Fig. 4, a vertical longitudinal section through the hood and a portion of the base of the can-soldering machine; and Fig. 5 is a top or plan View of the hood detached.

Reference being had to the drawings and the letters thereon, A indicates a plate adapted to be secured to a bench by screws passed through the apertures a at the corners of the plate.

B indicates the base of the machine, and is secured to the part A by bolts or screws passed through lugs b. The base is provided with a longitudinal slot, 0, over which is secured an adjustable support, (Z, by bolts 6 e,which pass through the flange f and the slot 0, with their heads resting upon the under side of the top of the base and their nuts resting upon the outer surface of the flange f. In the support (I is secured a vertically-adjustable bracket, E, by bolt h, passing through both and having vertical ELIIIlSt 'i, in which the shaft is is supported. The shaft 70 is provided with a disk, Z, to receive one end of a can, 0, and upon the shaft between the arms a z is located a spring, m, the tension of which is regulated by an adjustable collar, n, to hold the can in position while the heads are being soldered.

On the rear end of the bracket E is a lug, 0, to which an arm or lever, 19, is pivotally se cured. The bifurcated end q of the arm p embraces the shaft 70 and bears against an adjustable collar, 0", for regulating the throw of the lever 19, and to the opposite end, s, of the lever is attached apitman or rod,1,which is connected to a treadle, 2, for the purpose of releasing a can after either one of the heads has been soldered.

On the outer end of the shaft k is secured a cone-pulley, D, from which a belt may be conducted to any suitable source of power, or the shaft may be revolved by-a crank. (Not shown.)

On one end of the base B is secured a bracket, F, which is provided with a slot, 2, through which extends a bolt, u, by which it is secured to and adjusted upon the base. In the upper arm, n, of the bracket is secured a support, 10, which is provided with a socket, y, and oscillates upon the ends of thumb-screws a a, which pass through the sides of the arm n and enter recesses 12 b in the support to adjust the disk 0, which is supported to revolve in said socket and bears against the lower head of a can, and aceommodatesitself to a can which has not been correctly centered while it is being revolved for soldering the head thereto. The vertical oscillation of the support 10 is regulated, and the support held in position to place a can between the two disks, which bear against the can by a thumb-screw, cl, passing through an arm, e, ,on the outer end of the support and bearing against the outer surface of the arm n of the bracket F.

By the adjustment of the brackets E F the machine is adapted to solder cans of various sizes.

In the base 13 is formed a well, f, for solder, into which the can 0 projects at the end being soldered and is revolved therein. A soldering-iron, G, is supported in lugs g g,

projecting up from the surface of the top of V the base B, and is provided with a counterweight, h', to withdraw the end of the iron out of the solder as soon as a can is removed.

The iron is pressed down into the solder in the well f by the insertion of each can, and it applies the solder to the scam in the usual manner. I i

In front of the solder-well is a transverse slot, i, over which projects a vertically-adjustable deflector, k, secured under the bracket F, and directs a portion of the flame from the burner II against the head of a can to heat the head being soldered to the body. of the can. The flame from the burner envelops the well f, and is conducted up through a longitudinal. slot, Z, against the lower side of the soldering-iron G, as shown in Fig. 2, and is confined to the front end of the base by a transverse barrier, on.

As a further means for heating the end of the can being soldered an aperture, a, Fig. 4, is formed in the top of the base Ii, and over it is adjustably secured a hood, I, having a short nozzle or tube, 0, projecting therefrom for directing flame against any part of the end of the can being soldered. The hood is provided with a slot, 7), through which a lJhlllDb'SCl'OW, q, passes and engages with the top of the base 13.

By the use of the deflector 7.: and the hood I the ditliculty heretofore experienced in heating the can is entirely overcome, and by the present arrangement of the soldering iron it is removed from the solder after the operation of soldering and cannot become set in the lead as it becomes chilled, as in the device shown in the patent to which reference has been made.

Having thus fully described my invention, what I claim is- 1. In a can-soldering machine, the combination of abase provided with a longitudinal slot, a support movable in the slot for the upper end of acan vertically and longitudinally adjustable on the base, a vertically ad j ustable, rcvoluble, and oscillating support for the lower end of the can, constructed to oscillate freely, and a solder bath into which the lower end of the can proj ects, substantially as described.

2. In a can-soldering machine, the combination of a longitudii1ally-reciprocating sup port for the upper end of a can, a support for the lower end of the can, constructed and mounted to revolve and oscillate freely, and a solder bath, substantially as described.

3. In a can-soldering machine, the combination of a reciprocating support for the upper end of a can, a revoluble support if the lower end of the can constructed to oscillate freely vertically with relation to the solder bath, a vertically-adjustable bracket in which the lower support is mounted, and a device for limiting the degree of oscillation of said support and for holding it in position for the insertion of a can between the two supports, substantially as described.

1-. In. a can-soldering machine, a solder bath anda soldering-iron supported on one side of the bath with its working end normally out of the solder, in combination with means for automatically withdrawing the working end of the iron from the solder when a can is removed, and a suitable burn er, substantially as described.

5. In a can -soldering machine, a solder bath, an automatically-tilting solderingdron, and a slot in the base through which said iron is heated, substantially as described.

6. In a cansoldering machine, a solder bath, a slot in front of the bath, and a deflector for directing flame against the end of a can, substantially as described.

7. I11 a can -soldering machine, a solder bath, a slot in front of the bath, and an adjustable deflector secured to the base of the machine, substantially as described.

8. In a can-soldering machine, a solder bath, a transverse slot in front of the bath, and a longitudinal slot in the rear thereof, in combination with a soldering-iron and a burner, substantially as described.

9. In a can-soldering machine, a base having an aperture in it, in combination with a hood secured over said aperture to direct. flame against a can, substantially as described.

10. In a can-soldering machine, the combination of a base having a fla1ne-armrture therein, an adjustable hood over said aperture provided with a discharge-nozzle constructed to direct flame against a can, and a burner, substantially as described.

11. In a can-soldering machine, the combination of a base having a solder bath, a soldering-iron, a slot through the base in front of the bath, a slot in the rear of the bath, a hood, an aperture through the base communicating therewith for directing flame on one side of the bath, and a burner for supplying flame to the several flamc-directin g passages, substantially as described.

12. In a can-soldering machine, the combination of a base an adjustable bracket, an oscillating can-support in said bracket, and a deflector secured by the bracket, and a slot for supplying flame to the deflector, a reciproeatin g support for the upper end of the can, and aburner, substantially as described.

13. In a can-soldering machine, a base provided with a solder bath, a soldering-iron, a slot through which the iron is heated, a flameconflning barrier in the rear of the bath, a slot in front of the bath, and a burner, substantiall y as described.
