THOMAS HNRY HYDE, 0F NEW KENCINGTON, PENNSYLVANIA.

LATIrLMACHINE.

,To all rtf/mm muy confer/1,

lle it known that l. Tnoatas Hanni' Hrnr.,

a citizen of the i'vnited States, and a residentof New Kensington. in the county of vestmoreland and State of I Jennsylvania, have invented a new and improved Lath-Machine. of which the following is a full. clear, and exact description.

My invention relates to machines for expanding sheet metal into an open-work fabric. The present forms of machines of this character are objectionable in that they a re formed of a large number of parts which are quite apt to get out of order and the replacing of which parts is diflicult and expensive. y

An object of my invention is to provide a lath machine of a simplified construction. affording ready access to the several parts, and which is of an open type so that the work will not become jammed between the parts of the machine.

A further object of my invention is to provide a lath machine in which the cut finished fabric is flattened before it is delivered.

I attain the above outlined objects by running the sheet metal between a series of pairs lof rollers, the sheet being cut pirogressively from one edge by cutters carried in juxtaposition to said rollers and the cut fabric finally fed between straightening rollers to remove all kinks and bucklings from the fabric. f

.Reference to be had to the accompanying drawings. forming part of this specific: tion, in which similar characters of reference indicate corresponding parts in all the figures. and in which- Figure l is a plan view looking down upon a preferred embodiment of my invention; Fig. 2 is a side elevation of the same looking up from the bottom of Fig. l; Fig. 3 is an end elevation of the machine looking from the right-hand side nof Figs. l and 2: Fig. Je is an enlarged detail vertical sectional view through the last series of rollers and cutters and taken on the line l--t of Fig. 1 looking in the direction of the arrow: Fig. 5 is a plan view of the finished fabric: Fig. 6 is a transverse sectional view through the same and as shown, taken on the line (5 6 of Fig. 5. and Fig. T is a view similar to Fig. (l showing a portion of the unfinished fabric and showing part of the unperforated plate .in section.

Application filed May 10, 1912. YSerial No. 696,436.

In the several figures l have shown a suitable base S.. and mounted upon this4 base is an electric motor or other prime mover 9 actuating` a large gear wheel l0. whichgear wheel is rigidly mounted upon a shaft l1 extending longitudinally of the base 8 and suitably mounted in journal brackets l2. 13 and it. Also mounted on the shaft 11 and preferably forming one face of the gear l0. is a bevel gear meshing with a bevel pinion 16 mounted on one end of a transversely disposed shaft 1T. which shaftv is suitably mounted in spaced- apart journal standards 18 and 19 and terminates in a bevel pinion 20. which bevel pinion in turn meshes with a bevel gear 21. This bevel gear 2l forms the upper end of the first roller 22 of a series of parallelly disposed rollers which rollers 23 have their opposite ends journaled in bearing plates 2l and said rollers and bearing plates forming a roller mechanism for removing the kinks and irregularities from the cut fabric hereinafterdescribed. The rollers Q3 are inclined in three planes, so as to be in position to receive the substantially vertically disposed finished fabric as it leaves the cutting mechanism of the machine. Also mounted upon the shaft 'll a pair of spaced-airiart bevel gears "26 and 27. the bevel gear )Gi being position-ed ad jacent the journal bracket il and meshing with a bevel gear QCS mounted upon an upper shaft Q9. which shaft extends transversely across the bed and is suitably supported by a pair of spaced-apart brackets 30 and 3l. The end of the shaft. opposite the end carry ing the gear 28.` is enlarged to form an upper bearing drum abutting the outer end of which drum is a cutter 33 held in place by a jam nut Disposed parallel to the shaft Q9 and. in a horizontal plane with this shaft. is .a series of similarly shaped shafts each shaft being mounted on an independent bracket resembling the brackets 30 and 3l, and each succeeding drum being of less4 width than the preceding drum.'aiid the inner edges 3G of the drums being in alinement. so as to afford a gage forthe inner edge of the work 5T. the last drum 3i' adjacent the roller Q2 being of the least width. By this construction it will be seen that each of the cutters 33 is inset from the preceding cutter a distance equal to the desired width of each strand of the finished maferial.

While each of the shafts 35 may be driven direct from the shaft 11, preferably there is mount-ed on the end 'of each ofthe shafts 35 opposite the end carrying the drum, a gear 37 forming with the idler'gears 42, a train of gears between the shaft 29 on one end and the driven shaft 38 on the other end, which shaft 38 is connected bv a bevel gear 39 ,to the bevel gear 27 hereinbefore mentioned. Disposed ybelow the several shafts l29, 33 and 35, is a' lower roller shaft 40 mounted in the brackets and 31,and having one end terminating in a lower roller 41 coacting vwith the upper roller 37 to feed the material through the machine. 'The roller 41 is maintained in resilient engagement lwith the roller 37 by supporting the bearing carrying the shaft 40 upon a pin 44 disposed in a recess 45 in the bracket 30 and held in raised position by a compression s rin 46 which com ression s riiir is su J- ported upon a lower pin 47, said lower pin being in turn supported and regulated by a bracket 52 has a horizontally-disposed slit 55 therein, which slit is closed by means of As shown in Fig. 1, the work in the form of a long narrow metal sheet or plate 57 A hereinbefore mentioned, is inserted between the two largest rollers 32 and 41, and a narrow sho-rt strip of metal is cut and bent downward from the plate of the sheet by the shearing of'the'cutter 33 relative to the stationary cutter 51, as shown more particularly in Fig. 7. This cut forms one-half of j the diamond shown in Fig. 5. The material fis fed on between the next adjacent rollers and as the cutter coacting with these adjacent rollers is in-set, this next adjacent cut-ter and all succeeding cutters in order will`slit and bend down the next adjacent portion of material to form the coacting half of the previously formed half-diamond sheared by the preceding cutter in the series, and so on, each succeeding cutter shearing the iii-cut metal sheet to form .the coact-A ing portion of the half of the diamond previously formed, and at the same time forming one-half of the next succeeding dia- .mond. The tendency of this successive cutting and bending down is to turn the metal from the horizontalposition in which it is lfed into the machine into a more .or lessv vertically inclined fabric, as shown lin .Figsl and 6. The finished fabric is fed on he-'n' tween the rollers 23 to press ou't of the fabric all kinksl and irregularities formed therein.

Having thus described my invention, 1 clainias new and desire to secure by Letters Patent:
