v HANDLE-ASSFIFIBLING TEACHTNE.

Application filed January 3, 1920. Serial No. 34S,202.

Y 1o all w kom t may concern Be it known that i, BoLLrN L. Daarin, a citizen of the United States of America, and a resident of Fort- Arthur, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Handle-Assembling Machines, of which the following is a specification, reference being had .to the accompanying drawings, forming a part thereof.

My invention relates to the manufacture of sheet metal cans or containers and it has special reference to machines for assembling and lattaching solder to the handle parts of sheet metal cans or containers which may, for example, be suitable for dispensing oils and other liquids.

One object of my invention is to provide a machine of the aforesaid character that shallbe simple and durable in construction and eective and continuous in operation.

A further object is to provide a machine which requires only the services of unskilled attendants.

A well known type of handle for sheet metal cans or containers consists of a wire v loop flattened to provide a pair of parallel sides7 andhinge connected to the can by a. clip of sheet metal which is soldered to the surface of the can and has a flute or corrugation formed in it to embrace the handle.

vIt has been my aim to provide a machine for performing the preliminary operation, of attaching the handle to the clip and providing the clip with solder so that the handle and clip may readily be attached to the can of which it is to forma part. The method of assembling and attaching the handle to the can with its clip constitutes an invention which is independent of the .particular machine shown and described in this case and the aforesaid method constitutes the subject matter of my copending application Serial No. 849,203 filed of even date herewith. c

Other objects and advantages of my invention will be set forth hereinafter and i will now describe the same with reference to the drawings and point out the novel features thereof in the appended claims.

Referring to the drawings:

Figurel is a side elevation with certain of theparts broken away of a machine arranged and constructed in accordance with `my invention and constituting an embodiment thereof.

-A plan view of the same machine is shown in Figure 2. n

Figure c v3 is a partially sectional view which corresponds in general to the lefthand end of Figure 1, but is drawn to a larger scale and shows certain parts of the machine more in detail.

Figure 1 is a sectional elevation taken on the line 4.-4: of Figure 3.

Figure 5 is an enlarged detail view of the continuous chain or belt which forms a part of the machine of the previous figures but is drawn to a relatively large scale. The successive steps in assembling the handle `clip are illustrated by the several. links in the section of the chain shown in this figure.

Figure 6 is a longitudinal. sect-ionallelevationshowing one of the links of the chain of Figure 5, together with a portion of the adjacent links.

Figure 7 is an elevation of a single link of the chain.

Figure 8 is an elevation of the same link taken at right angles to Figure 7.

Figure 9 shows a handle loop before it is assembled but ready for use.

Figure 10 shows one of the clips ready to be used for holding the handle in place.

Figure 11 shows a solder blank which, according to `my inventionis soldered at predetermined points to the clip after the handle is assembled therein.

The resulting` combination or unit composed of handle clip. andsolder blank is shown in section in Figure 12.

The machine illustrated comprises a frame 15, a driving shaft 16, mounted in bearing blocks 17 thereon, a shaft 18 similarly li O by a track or channel. 28 on the trame l5 and the lower loose portion of the chain slides on a carrier or track 29 which is also mounted on' the frame. The chain moves when the shaft 16 is suitably driven in the direction of the arrows 30, the upper portion moving to the lett and the lower part to the right in Figure l.

A solder iux reservoir 3l is mounted on a suitable bracket or support 32 and is arranged to discharge onto a brush or wiper wheel 33 which engages the endless chain or belt and the handle parts mounted thereon as hereinafter explained.

A gas burner 34 is mounted within a housing 35 near the discharge end ot the inachine and is supplied with gas and -air through pipes 36 and 37. Shelves or shallow pans 38, 39, 40 are mounted on the :trame adjacent to the belt as clearly shown in Figure `2.

The endless chain is composed of a plurality of links which are detachably connected by open hinge joints 4l. Alternate links are provided with supporting blocks 42, the others having holes or openings 43 to cooperate with the teeth of the sprocket wheels.

'Each of the blocks 42 has a pair of lugs 44which are adapted to receive a handle loop 49 and which are provided with notches 45 to cooperate with notches 46 of another pair ot lugs 47 in providing a support or holder for a handle clip 48 as shown in Figure 10. The arrangement of parts is such that one of the clips 48 may first be mounted in the supporting block as shown at B in Figure 5, the handle loop 49 being then placed in position as shown at C. Finally a solder blank 50 which is of rectangular shape as shown in Figure 11, is mounted on the clip and extends across one side of the handle loop as shown at D in Figure 5. y

In operating the machine the pulley 22 is driven so as to produce a continuous movementof the belt as indicated by the arrows 30. An attendant lstands by each ot the pans 38, 39, v40 which are lilled respectively with the clips l0, the handle loops 9 and the solder blanks 1l. The direction of motion of the beltis such that the supporting blocks 42 comefiirst opposite the pan 38 and subsequently opposite the pans 39-40. The attendant opposite pan 38 places a clip in the supporting block as shown at B. When the supporting block comes opposite the pan 39 the attendant there stationed places the handle loop 49 in position as shown at C. Fipnally, when the block comes opposite the pan '40 i the attendant there stationed places a solder blank in position as shown at D. The

ysidesgofuthe lugs 44 and 47 are inclined so that it is easy to place the parts in the desiredpo'sitionas shown in Figure 6. This process 1s continuous and the assembled handle and clip are brought into engagement incassa with the flux wheel which is rotated by its engagement therewith, before the solder blank placed in position.

Finally, the assembled parts pass into the housing 3.3 and the gas llame from the burner 34 is so directed as to soften the solder at two opposite points designated 52 in F igure This seals the solder blank to t-he clip and holds the parts together and the handle in position. The assembled handles then drop ott of the belt'as the motion continues, a bin being preferably located underneath in 'position to receive them. The handles are then ready to be soldered to any desired sheet metal can or receptacle and this may be accomplished in any suitable manner. l prefer to employ a machine tor rapidly7 and eieetively accomplishing this purpose, but this forms no part ot my present invention and is described in my copending application Serial No. 349,201, tiled of even date herewith.
