SACK-FEEDER.

Application filed March 2, 1918.

(GRANTED UNDER THE PROVISIGNS 0F THE ACT 0F MARCH 3, 1921,

To all @07mm it may concer/n.'

Be it known that I, wl/'Inman Scor'r, a suhject of the Kingof Great Britain and Ireland, and a resident of Lochee, Dundee, Scotland, have invented certain new and useful Sack-Feeders, for which I have made application in England, dated J an. 16, 1917, Patent No. 110,077, of which the following is the specification.

This invention relates to feed mechanism for rotary sack-printing and like machines, of the type in which the material to be treated is fed by a single endless horizontally traveling cloth; and has for its object to improve the construction of such feeding` mechanism so that two or more attendants may be able to feed the machine in series at the same time and thus increase the output of the machine, while lessening the labor of each attendant. i

The improved feed mechanism comprises essentially a usual endless horizontally traveling feed cloth, a plurality of tables arranged in series on which is placed the material to be transferred by the attendants to the feed cloth, one or more of the tables eX- tending over a part or parts of the feed cloth and the last table being to the rear thereof, and timing rollers for each attendant so that the material fed to the cloth travels forward at the proper time.

An illustrative example of the improved feed mechanism as applied in connection with a rotary printing cylinder is shown on three accompanying sheets of explanatory drawings, Figure l, Sheet l, being a plan, Fig. 2, Sheet 2, a side elevation, and Fig. 3, Sheet 3, an end elevation thereof.

As shown in the drawings there works in conjunction with a rotary printing cylinder A an endless traveling feed cloth B supported by rollers C, D, E, one E of these rollers being driven in usual manner by gearing (not shown) from the shaft of the printing c linder. To enable two attendants to feed t e machine at the same time, two tables G,

are provided on each of which is placed a pile J of sacks or the like to be fed on to the traveling feed cloth B. One H of these tables is so made and placed, as shown, that its top extends over a part of the feed cloth B, one of the attendants feeding on to the cloth from the end of this table H neXt to the printing cylinder A. The other attendant Specification of Letters Patent.

Patented July 26', 1921. serial No. 220,055.

41 STAT. Il., 1313.)

feeds the sacks from the pile J on the other table (l on to the part of the upper surface of the feed cloth which is beneath the inclined rear part of the topl of the forward table H. Y If preferred the two tables Gr, H may be in one structure with a feeding gap where the feed cloth passes over the roller C.

Wvhere the foi-wart. attendant places the end of the sacks on his table I-I on to the feed cloth B there are the usual timing` rollers K, L carried and actuated as shown from a cam M on. a transverse shaft driven through gearing-N from the shaft of the printingy cylinder fr; and similar timing' rollers P, Q are also placed where the second attendant places the end of the sacks taken from the pile on the other table G on to the feed cloth. rfhese timing rollers P, Q are carried by a spindle supported in levers R, S journaled in the sides of the table I-l and connected by a stlrrup T with one end of a cord or chain U passing over guide pulleys V, W to the upper end of a lever X journaled in the framing of the machine, this lever being so shaped that a roller Y on it also bears on the timing' cam M. T his cam so acts through the gearing` described on the two sets of timing rollers l, L and I), Q that the sacks are fed onto the cloth I5 successively and travel forw( rd one after the other to the printing cylinder without interi'fering one with the other.

For triple .feeding there will be two tables the tops of which are above the traveling feed cloth and a third table to the rear thereof with the necessary timing` rollers for all three attendants, the traveling cloth being lengthened and the machine speeded up accordingly.

am aware that in feed mechanism applicable to'certain rotary sheet printing machines and sheet folding machines it has hitherto been proposed to provide a number of feeding tables and timing appliances regulating the delivery of the sheets; but in such machines there have either been a plurality of feed ways, or the feed mechanism has consisted of cloths,'webs, or tapes with or without grippers and` traveling in other than a horizontal plane only.

In the claims the word Number is to be understood to include one or more.

What I claim is zl. In rotary sack-printing and like machines of the type described; feedj1necha n1sm comprising` in combination an endless feed cloth traveling" 'only in a horizontal plane, a plurality "of tables arranged in series on which is placed transferred to the feed cloth, certain of these tables extending over the feed cloth and the last table being to thc rear thereof, and timing rollers for each attendant so that the material fed to the cloth travels forward at the proper time, as described.

2. In rotary sack-printing and like machines of the type described; feed mecha* nism comprising in combination an endless feed cloth traveling only ina horizontal plane, a plurality of tables arranged in series on which is placed the material to be transferred vto ythe feed cloth, one table extending over a part of the feed cloth, a second table tov the rear thereof, and timing rollers for each attendant so that the material fed to the clothtravelsl forward at the proper time, as

described.

3. In rotary sack-printingvand like mathe material to be V chines of the type described; feed mecha nism comprising in combination an endless horizontally traveling' feed cloth, a plurality of tables arranged in series on which is placed the material to be transferred to the feed cloth, certain of these tables extending over the feed cloth and the lastV table being` to the rear. thereof, usual timing` rollers for the forward attendant, timing rollersV for the rear attendantslevers supportingV these latter rollers, a stirrup connecting the levers7 a further lever ournaled at the forward ,end of the machine, a flexible connection between this forward lever and the stirrup, a roller on the forward lever and a timing` cam on which the roller bears, as described.

In testimony whereof l have signed my name to this specification, in the presence of two subscribing` witnesses.
