.Application filed March 29, 1915. Serial No. 17,787.

To all whom t may concern:

Be itknown that I, HENRY P. Hown, a citizen of the United States of America, and resident of Holyoke, in the countyv of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Paper Machinery, of which the following is a full, clear, and exact description.`

This invention relates to paper machinery to be especially employed in conjunction with a machine, or a portion of a Fourdrinier vpaper machine which in the forward feeding of the continuous web cuts the web into sheets and forwardly delivers the latter to form a pile,-the machine or adjunct constituting the present invention having forits purpose not only to effect the piling of the sheets advanced from the cutter, heretofore in many cases performed by a layboy, but alsoto conveniently effect a transferring of the pile, after the same has been sufficiently built up,`to a furtheradvanced position, leaving the place on the support at which the paper had been piled free or vacant for the taking on of another pile.

Other objects are attained by the present invention which, with the advantages thereof, will be hereinafter rendered apparent.

The invention is described in conjunction with the accompanying drawings and is defined in the claims. f

In the drawings z-Figure 1 is a plan view of the forward portion of a sheet cutting machine (or supplement of a paper making or other machine), which comprises the sheet -advancingand delivery feed tapes, and of the improved` piling and pile transferring mechanism. Fig. 2 is a side elevation of the saine. F ig. Sis a `partial sectional view as taken on line 3 3, Fig. 1, on a somewhat larger scale for clearer illustration of the parts, and the relations of the parts, shown therein.

In the drawings, A represents the forward part of a machine of common, well known,

and extensively used, character for cutting the continuous web coming to and through the same transverselyinto sheets. Included in this machine are roll supported and driven feed tapes a and b, the upper course Vof the one b having running engagements around the foremost roll d therefor which is positioned in proximity to and supportedl by the transverse gage bar B included in the present novel mechanism.

Describing the novel mechanism, C repre sents a suitable low frame having horizontal rotatable shafts f, f2 at the rear and forward portions thereof, each shaft having opposed pairs g and g2 of toothed wheels affixed thereon.

D represents an endless support or con veyer consisting of transverse articulated flat s lat's, each having in conjunction with its jointing pivot e, and inward projection It, these severally and successively having engagements with and between the teeth of the sprocket-like wheels g and g2 for acquiring a chain feed action for the slatted conveyer and support which is of a flexible character as apparent. The edge portions of the support and conveyer D,-at the upper course thereof, are sustained on ledges z' longitudinally ranging at opposite sides of the frame, whereby such upper course is prevented from sagging, and remains fiat and horizontal.

@ne of the shafts f2 carrying the toothed wheels g2, g2 has means for manually rotating it, such, for instance, as the crank handle f2.

E represents a longitudinally ranging gage board supported by brackets E2, E2, and extending above a rear end portion of the upper course of the jointed slat conveyer and coincident with, or adjacent to, the rear longitudinal edge of the latter.

The aforementioned transverse gage board B has its location above the rear end portion of the conveyer and it is vertically adjustably movable in conjunction with the aforementioned feed tape roll CZ and has means for effecting its rising and lowering movements which will be now described.

On the upright frame extensions C2 at the rear, andupstanding above, the frame proper C are a pair of horizontal transverse shafts G and G2 having sprocket chains H H running around the sprocket wheels J and J2 which are aiiixed on, and near the opposite ends of, the respective shafts Gr and G2.

The forwardly locatedvertical courses of the frame extensions C2.

Any'suitable means are provided for rotating the sets of aforementioned shafts and sprocket wheels for effecting the elevation of the gage board and the lowering thereof as from time to time is required in making use of my improved mechanism Y 'In the present instance an intermediate shaft L is provided parallel with the shafts G and G?.

On this shaft L is affixed a sprocket wheel 0, shown as outside of the frame extension and above which, on a suitably extended portion of the upper shaft G is a similar sprocket wheel p around which runs a somewhat shorter endless sprocket chain g. The shaft L has the comparatively large hand wheel L2 thereon by means of which through the connections described the transverse gage bar or board B is operated.

The aforementioned brackets lo 7c carried as rearward extensions of the gage board B form supports for the horizontal shaft t which s affixed therein and on which the aforementioned forward tape roll cl continuous for its entire length, or divided into a series of short spools, is mounted.

The aforementioned gage board B also forms the primary support for the yieldable rollers o o which are above and coact with the advanced portions of the feed tape, which round the roll d for preventing the paper, forwardly moving over andacrossthe gage board, from being upwardly deflected in any undue extent. As specifically shown,

A these rollers 'v are carried on the free. ends of arms o2 which are hung for rocking movements on a cross rod or shaft o3 sustained by xed arms or brackets 'U4 forming rigid eX- tensions ofthe cross rod t before mentioned as supported on the gage board provided brackets c. Y

The sprocket chain g and sprocket wheels 79 and o are duplicated at the rear of the machine, the sprocket chain g2 there shown having a counterbalancing weight w thereon, for preventing when-not desired, the lowering of the vertically adjusted gage board and for insuring on the turning of the hand wheel L2 the easy elevation, more or less as desired, of the gage board.

In the operation and utilization of the improved mechanism described, the sheets cut from the continuous web are advancedby the feed tapes over and forwardly beyond the gage board B and onto the normally stationary support constituted by the upper course of the conveyer D. The attendant squares the sheets with their rear ends edgewise against the transverse gage board and with their rear sides edgewise along the back longitudinal gage board E. As the pile grows in height, the gage board B is elevated through the turning of the hand wheel L2,- the roll-rounding forward portions of the tapes the tape rollcZ and the yieldable rollers o being bodily carried thereby and movable in unison therewith so that the relations of the tapes and rolls to the gage board are invariable. After the pile or stack of sheets has become quite high, the gage board E having, from time to time, been elevated step by step, the conveyer is operated manually by turning the crank handle at the forward end of the machine to move the high and heavy pile away from the position on the conveyer' at which it had been built up so that the operation of further stacking or pile building against the gages need not be at all interrupted for the removal of the already made pile to a different place.

It isa matter of considerable convenience and saving of time to have one made pile on the forward portion of the support and conveyer D while another pile is being formed on the rear of the conveyer, inassheets into ream lots may do so' from the transferred pile, the only shifting being of the counted lots from off the pile to the proper place of occupancy therefor.

I claim l. In a machine. of the character described, in combination, a frame, horizontal rotatable shafts mounted transversely on said frame at the rear and forward portions of 'much as the person having to count the the latter, having toothed wheels thereon,V y

mounted above and transversely relatively to the rear upper portion of the conveyer, means for imparting an elevating adjustment to the transverse lgage-board, and means for feeding sheets over the transverse gage board onto the portion of the conveyer adjacent thereto, comprising endless feed tapes and sets of rollers therefor, the rollers for the advanced portions of the feed tapes being supported by, and bodily movable` with, the transverse gage board, and yieldable rollers, above and coacting with said advanced tape-rollers, and bodily supported ly aid movable vrelatively to the said gage oar 2. In a machine of the character described, i

in combination, a frame, horizontal rotatable shafts mounted transversely'on said frame. at the rear and forward portions of the latter, having toothed wheels thereon,

an endless support and conveyer consisting of articulated transverse slats having engagements around said wheels, the upper course of which constitutes a table,.means for manually rotating one of the` wheel-carrying shafts, a longitudinally ranging gageboard on said frame and upstanding above a rear portion of the upper course of the jointed slat conveyor, a gage-board movably mounted above and transversely relatively to the rear upper portion of the conveyer, having brackets extended therefrom, vertical rods supported by the frame With which said brackets have guiding engagements, a pair of shafts one above, and the other below, the transverse gage-board, having pairs of sprocket Wheels thereon, sprocket chains around the sprocket Wheels, for- Wardly located vertical courses of Which have connections with said brackets, means for manually rotating one of said shafts, and means for feeding sheets over the trans- 15 verse gage-board onto the portion of the said conveyer adjacent thereto.
