i v Application filed November6,1882. (NomodeL) t i To all whom it may concern: i

Be it known that I, CONRAD KAHLER, residing at Chicago, in the. county 'of Cook and j Stateof Illinois,iand' a citizen of the United States, have inventedhanew and. useful Im proveinent in Printing-Press Folders, of which i ,the following'is a full description, reference being hadtotheaccompanying drawings, in

The invention consists essentially in thecombina'tion, with upper and lower traveling tapes, t of a divider arranged to direct the front edge- 3 5 of an advancing sheet past or by therearedge of a sheet which has ipreviouslyientered between the tapes and been stoppedin its movement, whereby two or more: sheets can be ent mnlatedldirectly uponeach other to befolded together or for other purposes. Theinvention' embraces other features, which will'be fully hereinafter described, and set forth in the i claim's. t p i i a In the drawings, Aindicates the fram e-work;

The frame A may be madein the form shown or of such other form and dimensions as will be suitable to adapt it to the press and room in which the folder is to be placed for operation. a a

The rollers B O, as beforeistated, will beilongto'theprinting-press when the press and folder are not supported in the same frame.

When the press and folder are built together,

then they will be connected as shown, other the rollers B (l in the position shown. It will be understood that the folder here shown is designed to he used i'nconnection with a per= fecting web-printing press, or a'press printing upon paper carried in by the press from Wise secondary posts for supporting thetapei as to bring'these tworollersin reference to ICC \ the roll without cutting or severing until it is printed on both sides, and for this reason I have shown the breaking-roller D, which said roller will not be required in presses where the ordinary folder, and'such additional rollers as will give the desired number of folds will be placed below them. As I have. not improved this part of the folder, I have only shown one pair of folding-rollers with their accompanying folding-blade Q. In rear of the breakingrollers D J,and in proximity thereto, is placed the shaft afor operating the dividers, switches,

-or guides b b b, which rod is suitably supported and journaled in the frame. It is provided with the switcher guide fingers b, which guide-fingers are provided with heels orrrear projectionsfor holding up the rear ends of the sheet or half-sheet of paper which is passed overthem, which sheet is stopped by the plates j before it is passed entirely 01f from the heels of the fingers or blades 1), so that when the sheet or half-sheet passes under these fingers or blades it will be certain to pas'sunder thesheet which has preceded it, and is there resting against the stop. In the modification. of these fingers shown at Figs. 8 and 9, the shaft a is placed over both sets of tapes, and the fingers or guides I) work from above and are made curved, so as to act as hooks for hooking the rear edge of the first sheet or halfsheet, which has been stopped, to insure the under passage of the followin g sheet or sheets. The rocking of the shaft will inits movements alternately drop and pick up the rear edge of the stopped sheets, so. that by the use of this the form shown in Fig. 8, the machine is to be so timed as to lift the rear edge of the stopped sheet or sheets, so that thead vancing, sheet will pass under the stepped sheet or sheets and, will let the sheets down again upon the lower set of tapes. In this form I) the shaft or is made rotary instead of being made to'rock or vibrate, and I have shown at Fig.

- 13 suitable gearing for rotating it'and timing it to lift the rear edge of the sheet or sheets at the proper time for the advancing sheet or half-sheet to pass under the stopped ones,and as in this rotary form the fingers move in their travel in the same direction as the printed sheets they can be made to operate when the printed sheets follow each other with only a narrow space between them, and as these fingersb do not pass into or out of any space they move along and get out of the way. The object of these several forms is to cause the advancing sheets to pass under the stopped ones.

The stop rod or shaft i crosses the folder, andis suitably supported and journaled in its frame-work. This rod is located below the tapes, immediately below the lower ones, and is provided with the plates or fingers j, which operate between all or a portion of the tapes, and cross the space between the two sets, as shown. This rod may be located above the tapes; but I prefer the position below, as shown, for the reason that it is designed to be turned as soon as the last sheet to be cumu- I lated reach-es it, the upper ones having been brought to a full stop, and in starting have a sufficient time to resume their original movements, so as to take the same speed as the as shown the rod or shaft i is rocked by the arm is, the connecting rod or link 1, and the cam-lever n, the upper end of which lever is provided with an anti-friction :roller. As. the

cam-wheel Mrevolves the short arm of the le-' "er a is held out, as shown, which position throws the long arm. of the lever forward and holds the stopsj in the vertical position shown for. stopping the sheets in their path of travel.

As'the wheel M rotates the short arm of the lever 41. drops into the depression 0 and brings the springs m into operation, which, by means of the arm k, rocks the shaft 1 and throws the stop down into the position shown in Fig. 7. The spring m is operated by the pendant or support 1;, which-is attached to the frame, and the stop g, which is attached to the rod. There is the same arrangement for the spring e, pendant f, and stop g on the opposite side, working in connection with the cam-wheelor disk L, for rocking the shaft a at the proper intervals of time.

The stops'g g may be provided with screwthreads, so as to increase or diminish the tensions of the springs e m.

The action of the rod d and its springis the same as that of the rod 1, except that it may have a direct connection with the cam-wheel L by its anti-friction wheel h, Fig.1,the spring 0 being arranged to hold the rear end of the said rod against said cam-wheel L.

When the shaft or is made rotary, as shown in Figs. 12 and 13, then the gearing shown in Fig.13 is added, and the devices for rocking the shaft or shown in Fig. 1 may be omitted,
