Specification of Letters Patent.

Patented Mar. 18, 1919.

Application filed June 17, 1918. Seria1'No.240,489.

To all whom it may concern:

Be it known that I, DELBERT I. MOMAHAN, a citizen of the United States, and resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Machine for Cleaning and Repairing-Radiators, of which the following is a specification.

The object of my invention is to provide a radiator repair machine of simple, durable and inexpensive construction.

-More particularly it is my object to provide a machine of the class mentioned havinga receptacle for receiving an acid or other suitable material for cleaning a radiator, and to provide an adjacent receptacle with a crane arm adapted to move the radiator from one receptacle to position adjacent to the-other receptacle or to or-from an independent support.

A- further object is to provide above the second receptacle a movable rack or Supporting member for holding a radiator in different positions above the second receptacle.

-Still a further object is to provide a receptacle, which is the second one above '[mentioned, for molten solder having a laterally projecting cup or the like into which a ladle may be inserted'for taking out molten solder for pouring the solder through the radiator.

"With these and other objects in view my invention consists in the construction arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical,-sectional view through a radiator repair machine embodying my-invention.

'Fig. 2 shows a side elevation of of the solder receptacle.

Fig. 3 shows a top or plan view of the machine.

Fig. 4 shows a horizontal, sectional view taken on the line 44 of Fig. 1.

r Fig. 5 shows a detail View of the'crank shaft for the crane.

Fig. 6' shows a vertical, sectional view a part J taken onthe line 66 of, Fig.4.

Fig. 7 shows a detail, plan view of the lower bearing for the crane.

Fig. 8 ;shows' a vertical, sectional view taken on the line 88 of Fig. 2; and

Fig. 9 shows a sectional view taken on the line 99 of Fig. 1.

In the accompanying drawings, I have used the reference numeral 10 to indicate generally the large tank or receptacle for acid or other cleaning liquid. The tank 10 is preferably supported on legs 11. In the bottom of the tank 10 is a plurality of spaced ribs 12 upon which the radiator or the like may rest for spacing it above the bottom of the receptacle, and thereby allowing the fiuid in the receptacle to have access toall parts of the radiator.

Adjacent to the receptacle 10 is a receptacle 13 for molten solder.

The side walls of the receptacle 13 project beyond the end thereof adjacent to the receptacle l0 and may be detachably secured to the receptacle 10 by means of angle-irons 15 riveted to the receptacle 10 and bolted to the projecting ends of the side walls of l the receptacle 13. The receptacle 13 is substantially supported by the legs 11.

In the bottom of the receptacle 13 is a downwardly extending transverse channel 14. Atone end of the channel 1a and outside the receptacle 18 is a cup or the like 15 which communicates at its lower portions by means of an opening 16 with the lower part of the channel 141-. The cup 15 has a hinged cover 17. f

Underneath the receptacles above described is a fuel supply tube 18 having a plu-' rality of burners 19 located respectively beneath the receptacle 10 and the channel 14. A suitable frame member 20 is supported upon the adjacent walls of the receptacles 10 and 13. a

The supporting member 20 has on its upper surface an annular rib 21 shown in Figs. 6 and 7.

For easily handling the radiator I have provided a crane arm 22 which rests upon the member 20 and is extended upwardly therefrom and has a curved upper end, as illustrated in Fig. 1. The crane arm 22 is channel-shaped, as illustrated in Fig. 4:.

-Infthe lower end of ,the rcrane arm 22 is cleaningfluid and the solder.

fixed a rigid block 23 having on its lower surface a rib 24 designed to coact with the rib 21' for forming a turn-table.

A bolt 25 extends through the block 23 and the member 20, as illustrated in Fig. 6, and down through a flange on the receptacle 10, and securely connects the block 23 of the crane arm 22 with the member 20, while per-- mitting rotation of the crane arm.

On the crane arm 22, near the lower portion thereof, is mounted a transverse shaft 26 on the ends of which are crank arms 27. On the central portion of the shaft 26 is a drum 28. On one end of the shaft 26 is a ratchet 29 adjacent to which is a pawl 30, designed to normally engage the ratchet 29 and to hold it against rotation in one di rection.

WVound 011 the drum 28 is a flexible member such as the cable 31, which extends upwardly along the open side of the crane arm 22 over suitable guide pulleys 32 on said crane arm. Connected with the outer end of the flexible member 31 is a plurality of shorter flexible members 33 having at their ends hooks 34 for engaging a radiator.

Mounted in the upper forward portion of the receptacle 13 near the side thereof adjacent to the receptacle 10 is a transverse shaft 35.

Mounted on the shaft 35 is a pair of upwardly and rearwardly extending spaced arms 36, which are connected at their ends by a cross member 37. The members 36 and 37 have in their upper surfaces chanpils for receiving asbestos strips 38 or'the At the pivoted ends of the arms 36 are suitable stop members 40. The arms 36 are provided near the cross member 37 with downwardly extending curved rack bars 41.

Suitably mounted in the walls of the re ceptacle 13 is a transverse shaft 42 on which are spaced gears 43 which mesh with the respective rack bars 41.

In the outer ends of the shaft 42 is mounted a ratchet 44 and adjacent thereto on said shaft is a crank handle 45.

A pawl 46 is pivoted on the frame of the receptacle 13 to coact with the ratchet 44.

In the practical use of my improved radiator'cleaning and repair device, the acid or cleaning fluid is placed in the receptacle 10 and the solder is placed in the receptacle 13.

The burners 19 are lighted for heating the The crane arm 22 is rotated to the desired position and the hooks 34 are fastened to a radiator which is to be cleaned and repaired.

The crank 27 may be used for raising the radiator whereupon the crane arm 22 may be rotated for swinging the radiator to position above the receptacle 10.

After the radiator has been cleaned the crank arms 27 may be used for again raising it and the crane arm may then be swung around to position for holding the radiator above the arms 36. The radiator may be lowered upon the arms 36 and will be held in proper position by means of the stops 40..

By means of the crank 45 the adjustable radiator holding frame, consisting of the arms 36 and 37, may be adjusted for holding the radiator at any desired position or angle for pouring through it the molten solder. The molten solder is dipped from the cup 15 and poured through the radiator until the repairing process is completed.

The convenience of a device of this kind is obvious from an inspection of the drawings. V v

The radiator can be handled in a simple and eifectivemanner and requires almostno touching by the mechanic. V

The necessity for heaving and lifting is practically obviated.

The radiator may be shifted to a great variety of positions for pouring molten solder over the parts to be repaired, by adjusting the positions of the arms 36 and turning the radiator around on said arms. 7

This is important for the reason that it is sometimes necessary to drop the molten solder between the tubes of the radiator for closing a hole in a tube, which is not readily accessible to the mechanic from the outside of the radiator. By tilting the radiator to different positions, a position can be reached where the solder can be applied directly on the parts to be repaired.

Some changes may be made in the construction, and arrangement of the parts of my improved device without departing from the essential features and purposes of my invention, and it is my intention to cover 105 by my claims any modified forms of structure or use of mechanical equivalents, which may be included within their scope.-

I claim as my invention:
