SPECIFICATION forming part of Letters Patent No. 783,789, dated :February 223, 1905.

Application iiled November 18, 1904. Serial No. 233,385.

To /r/ZZ whom, '1T/2 may concern:

Be it known that I, OLIVER J. JonNsoN, a citizen of the United States, residing at l/V heeling, in the county of Ohio and State of l/Vest Virginia, have invented a new and useful Improvement in Horn-Supports for Soldering- Machines, of which the following is a specilication.

This invention relates to that type of machines for soldering the longitudinal side seams of can-bodies in which the can-bodies encircle and are supported by a horizontal horn, along which they are moved or fed past the soldering devices; and the invention re lates more particularly to the means for supporting the outer or discharge end of the horn.

The object of the invention is to provide a support for the end of the soldering-horn, of simple and desirable construction, which will adequately support the horn and will not impede the ready passage of the can-bodies off of the horn or mar the can-bodies.

In the accompanying drawings, Figure 1 is a fragmentary side elevation of the discharge end of a can-bodysoldering machine provided with a horn-support embodying' the invention. Fig. 2 is a plan view thereof, the can-bodies being in section to expose the horn. Fig. 3 is a transverse sectional elevation thereof, on an enlarged scale, in line 3 3, Fig. l. Fig. fl is a longitudinal sectional elevation, on an enlarged scale, of a hornssupitiort of different construction. Fig. 5 is a transverse sectional elevation thereof 1n line 5 5, Fig. 4.

Lilie letters of reference refer to like parts in""the several figures.

Referring to Figs. l to 3, A represents a portion of the frame of a ca'nJbody side-seam soldering-machine, and B a portion of the solm der-box. These form no part of the invention and may be of any usual or suitable construction.

C represents the supporting-horn for the can-bodies. In the construction shown it eX- tends horizontally over the solderb`ox and preferably, though not necessarily, consists of parallel separated bars or rails of segmental circular cross-section which are connected and4 spaced apart by spacing'blocks or the like c,

located at intervals along' the length of the horn. The receiving end of the solderinghorn, which is not shown, may be supported in any known way. The can-bodies encircle and are supported by the horn while they are moved intermittently along the same by feed mechanism, which in the construction shown consists of feed-dogs al, which engage the rear ends of the can-bodies and are pivoted to horizontal feed-bars D, which are arranged at opposite sides of the horn and are reciprocated lengthwise by a rock-shaft lil, which is journaled on the frame A beneath the horn and has arms r, connected by links r/ to the feedbars. rlhe rock-shaft is oscillated by suitable power-operated links f, connected to depending armsf, fixed tothe rock-shaft. Upon each movementof the rock-slnift in one direction the feed bars and dogs move forwardly, and the dogs engaging the rear ends of the several can-bodies move them all forward one step, and upon each opposite movement of the rock-shaft the feed bars and dogs are moved rearwardly, the dogs being thrown outwardly or away from the can-bodies and returned past the latter, which remain stationary, and then being thrown inwardly to engage the rear ends of the bodies to move them forwardly another step at the next forward movement of thefeed-bars- This feed mechanism, which is fully described in my appli cation for United States Letters Patent, liled April 15, 19025, Serial No. 152,733, preferably employed, because the dogs have very little or no tendency to displace the can-bodies in their return movements and no means are required to hold the bodies stationary during the return movements of the dogs. Other intermittent-feed mechanism for can-bodies could, however, be substituted.

G represents a roller which is arranged heneath and supports the discharge end of the horn. lt preferably has a concave periphery to conform to the circular shape of the horn and can-bodies and a central circumferential groove l to prevent contact of the roller with the soft solder on the can-seams. The roller is journaled to turn freely on a support or carriage H, which reciprocates horizontally with the feed devices, so that the roller, which l are unnecessary.

bears ag'ainst the horn between the adjacent ends of two can-bodies, as shown in Fig. l, will move forwardly with the bodies and will maintain its bearing on the horn between the bodies during the entire forward movement of the latter'. 1n the construction illustrated in the drawings the roller rotates on'ballbearings about an axle if', fixed on the reciprocating carriage H, which is supported and guided on stationary horizontal tracks or guides K, secured at opposite sides of the carriage to fixed brackets rising from the main frame. The tracks enter grooves in the opposite sides of the carriage. The latter is reciprocated with the feed devices by links Z, pivotally connected at opposite ends to the ends of the roller-axle and operating rockarms for the feed devices. While the abovedescribed construction .of the horn-support and its reciprocating means is simple and efficient, a reciprocating support for the horn differently constructed and operated could be employed.

In the operation when the can-bodies are advanced along the horn by the feed mechanism the roller-support Gr moves with the canbodies and bears and rolls directly against the horn in the space between the two adjacent can-bodies. The cans are not forced forwardly between the horn and the supportingroller, so that the forward movement of the bodies by the feed mechanism is not opposed and the feed-dogs do not mar the ends of the bodies. Then the feed devices return, the canbodies remain stationary, the feed-dogs moving rearwardly past the bodies, and the supporting-roller, which returns with the feed devices, rolls against the under side of the body immediately in rear of it and engages the horn in the space between this and the next can-body. The supportingroller engages the can-bodies only while they are stationary, and as it rolls on the bodies it has little or no tendency to move them rearwardly on the horn, and the usual dogs or devices for holding the bodies from rearward movement Thus the edges of the canbodies will not be dented or marred in either the forward or rearward movement of the feed devices and supporting-roller.

Figs. 4 and 5 illustrate a horn-support on which the horn bears directly and which moves in forward direction with the can-bodies and does not at any time bear on the can-bodies. It is especially adapted for machines of the continuous type in which the bodies are advanced along the horn by an endless feedchain or thelike D@ This su pportcomprises a series of supporting-rollers G, similar to that described, whose axles travel and bear in camways or grooves g' in stationary cam-plates g2 at opposite sides of the horn. The camgrooves are circular, except at their upper portions, where they are straight and parallel with the horn for adistance somewhat greater than the length of a can-body. The ends of the roller-axles which enter the cam-grooves are preferably provided with antifrictionrollers g3. The axles of the supporting-rollers are moved along in the cam-grooves in the same direction and at the same speed as the can-bodies move on the horn by a rotating carrier H, which is driven by any suitable mechanism L' and is provided with radial slots LZ, through which the roller-axles extend and in which they slide. i/Vhile the rolleraxles are passing through the straight portions of the cam-grooves the rollers are held in direct contact with the horn between adjacent can-bodies and support the horn. In this support the rollers do not move rearwardly and never bear on the can-bodies. This support is also adapted for use with an intermittent-feed machine by driving the carrier H intermittently.

The horn is preferably provided at that portion beneath which the supporting roller moves with short bearing-strips m., which are secured between the lower portions of the separated horn-bars and increase the bearing'- surface for the supporting-roller.
