DEVICE FOR PILING PAPER.

SPECIFICATION forming part of Letters Patent No. 503,576, dated August 22, 1893.

Application filed September 24, 1892. Serial No. 446,774:- (No model.)

To all whom t may concern/.-

Be it known that I, THOMAS A. Braces, of Arlington, in the county of Middlesex, in the State of Massachusetts, have invented new and useful Improvements in Devices for Piling Paper, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of machines or apparatus which are designed to pile up in a neat and even manner sheets of paper issuing from a printing machine or other machine operating successively on single sheets. And the invention consists in an improved organization of a machine which eifects the aforesaid piling of paper in an expeditious and more accurate manner, as hereinafter fully described and set forth in the claims.

In the annexed drawings Figure lis a side elevation of apaper piling machineembodying my invention. Fig.2 is aplan view of the same. Fig. 3 is an enlarged plan view of one side of the paper receiving bed and paper adjusting device employed therewith. Fig. a is an enlarged side elevation of said part of the machine. Figs. 5 and 6 are respectively an enlarged plan view and an elevation of the at tachment of the paper abutment to the paper receiving bed, and Fig. 7 is a plan view of a modiiication of the means for transmitting motion to the laterally movable paper adjusting plates.

Similar letters of reference indicate correspending parte.

A-represents the oscillatory liy which delivers single sheets of paper successively from a printing machine or other machine onto a table mBm on which said sheets are to be deposited in a smooth and evenly piled condition. To accomplish this smooth and even piling of the sheets of paper in an expeditious and reliable manner and by simple and efficient means I have resorted to the following construction and combination of mechanisms.

Upon the table MB* I mount my improved paper receiving bed which is provided at the end adjacent to the heel or pivoted end of the iiy with suitable stops or abutments IJ-1J- parallel with the axis of the fly and receiving one edge of the paper piled on the said bed. The peculiarities of my said paper receiving bed consists in the inclination of the paper supporting surface thereof toward the aforesaid stops or abutments. Saidinclination caus ing the sheets of paper, as they are thrown onto the bed or pile resting thereon, to slide automatically to the said` abutments. In addition to said inclination my improved paper receiving bed possesses the novel and important feature of being concaved longitudinally or formed with a depression across its center. The paper is thus curved when dropping onto the bed. The curving of the side edges of the sheet stiffens said edges and obviates the liability of bruising the same by their contact with the laterally moving plates which push the sheet into its requisite position on the bed as hereinafter described.

My invention also consists in the following novel features of the details of the aforesaid paper-receiving bed and devices employed in connection therewith. Said bedl preferably form of shoes -C-O- which are firmly secured to the top of the table -B- and are inclined toward the` side of the table adjacent to the fly -A- and concaved in the same direction as shown in Fig. l of the drawings. In order to allow the said shoes to be adjusted laterally in their positions I provide them with perforated ears -O-- on their under sides, through which ears passes a horizontal shaft D which is secured to clips -F- fastened to the table. By means of a set-screw -tpassing through one side of each ear -C- and engaging the shaft, the shoes are retained in their adjusted positions. Upon the tops of the said shoes I fasten thin steel leaves ct-awhich are bent to conform to the concaved surfaces of the shoes and terminate with their free ends at or near the edge of the table adjacent to the iiy -A- where the abutments b-b are secured to two or more of the leaves. Each of these abutments I prefer to make detachable from the leaves by attaching it by means of jaws -c-c-' mounted side by side on the leaf and formed with hooks CZ-d by which they engage opposite edges of the leaf as more clearly shown `in Figs. 5 and G of the drawings. The jaw -chas affixed to it a vertical plate which forms one of the abutments Mb. The top of said jaw is formed with a smooth bored ear cand the other IOO jaw c-- has a screw-tapped ear, and into said ears is inserted the clamping bolt -eby means of which the jaws are drawn t0- gether and made to firmly grip the leaf .ct.

In connection with the described paper-'receiving bed I employ laterally j oggling plates -P-P- which stand vertically and inlines paper resting on the aforesaid bed. These plates are firmly mounted on a reciprocating horizontal bar -gwhich extends across the bottom of the bed and receives motion by a suitable lever -Z- which is oscillated by a pitman -f-- actuated automatically with the movementof the fly. By mountingthe plates -P-P- on one and the same bar they are compelled to move synchronously and, by the reciprocating motion of said bar, ,said plates are caused to alternately approach and recede from opposite edges of the pile of paper and of the sheet which is in process of being deposited on the pile, and by the contact of the said joggling or laterally moving plates said sheet is guided and properly adjusted so as to come perfectly even with the side edges of the pile while the sheet automatically slides onto the stops or abutments -b-bwhich brings the abutting edge of the sheet flush with the edge of the pile.

By the movement of the plates IP-P- simultaneously in the same direction, only one of said plates at a time is allowed to touch the paper, and consequently the liability of pinching and retarding the movement of the sheet in transit on the table is effectually obviated.

In order to allow the plates -P--P- to be adjusted in their positions to accommodate between them piles of paper of different widths,I mount said plates longitudinally adjustable on the bar -g--, and this I prefer to effect by attaching each of said plates to a bracket -j, the base of which is formed with a clamp -;7" similar to the jaws --c--c.- by which the abutment -bis attached to the leaf -aas hereinbefore described. A bolt -j-' inserted transversely in the clamp -jfastens the same to the bar -g. The lever -Z- which transmits motion to the bar -g-v I prefer to pivot to the Clip -F-. One arm of said lever may be either pivotally connected to the end of the bar -gas shown in Figs. l, 2, 3 and 4 of the drawings, or provided with a toothed segment n engaging a rack -n on the bar -gas shown in Fig. 7 of the drawings. The other arm of said lever is connected to the end of the pitman f` which receives reciprocating motion from the crank I of the fly-shaft;

In order to permit the pitman to be adjusted to a longer or shorter stroke and thus regulate the motion of the plates -P-P- accordingly, I mount on the pitman two lugs n-h--h respectively at opposite sides of the wrist-pin of the crank -I- which engages alternately said lugs and thereby pushes the pitmen alternately in opposite directions.

VSaid lugs are permitted to be shifted longitudinally on the pitman to set them at a greater or less distance apart, and by means of set-screws connected to the lugs and engaging the pitman said lugs are retained in their adjusted positions.

Iuasmuch as my invention is designed to be applicable to printing machines and other machines of the class hereinbefore referred to already in use as Well as to such machines in process of construction, IV mount my inventionV on a table -B- separate from the frame of the aforesaid machine, and make the pitman adjustable in its length by'forming the same of two parts spliced together by a clip fattached to theinnerend of each part and embracing the body of the other part and clamped thereon as best seen in Fig. 2 of the drawings.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A paper-piling apparatus comprising a paper receiving bed, abutments rising from said bed to receive one edge of the pile of paper, and vertical plates movable simultaneously in the same direction in lines at right angles to the aforesaid abutments and engaging one at a time opposite edges of the pile of paper as set forth.

2. In combination with the paper transferring fly, a paper-receiving bed having abutments for one edge of the pile of paper adjacent to and parallel with the axis of the iiy, and said bed inclined toward the abutments, and laterally joggling plates at right angles to the said abutments and alternately engaging opposite edges of the pile of `paper as set forth. f

3.
