Referring to the drawings, l designates a printing-machine consistingof a'frame 2, in

which is mounted the driving-shaft 3, carryingthe driving-pulley 4, to which power is imparted from any suitable source, said shaft 3 also carrying the'fiy-wheel '5 and having a pinio n/therejon, which meshes with a main drive-gear 7, which is--mounted upon the prank-shaft 8, the latter carrying the bedcranic or separating-cam 9, which is in suitable engagement with the bed connection-arm 10, the latter being pivotally connected in any suitable manner, as by means of the pin 11-, with the type-bed 12-, which latter is mounted in a suitable portion 13 of the frame and which serves as a guide for said type-bed, it being understood that as the bed-crank cam 9 is rotated it imparts a reciprocating motion to the bed connection-arm '10, which thus reciprocates the type-bed 12 in order to bring the same into proper relation with the platen 14, suitably supported upon the frame 2 of the machine in order to make an impression. Also with the bed-crank or separating-cam 9 is the sheet-separator lever 15, which latter is fulcruined upon the shaft 16, suitably carried in the frame of the machine, said lever 15 being in the form of a yoke at its u perportion and extending beyond the she t 16 and its ends 19 serving as a support for the shaft 17, said shaft having an opening 18 therethrough and upon which is mounted a feed-gripper cylinder 20, said shaft 17 also carrying the gear 21- and said'cylinder being suitably provided with air-passages 22 therethrough extending to-the periphery thereof and communicating with the opening 18 in the shaft.

23 designates a cam which-is mounted u on the upper end 19 of-yoke 15 and with w iich is adapted to be brought into contact at the proper time the nose of the lever 24, which is suitably connected with a rod 25,

carried by the feed-grippercylinder 20, said rod carrying the grippers 26, which are situated adj acent'the opening of the passages 22, it being understood that as the lever 15 is actuated by the bed-crank or separating-cam 9 the feed-gripper cylinder 20 and its adjuncts are reciprocated toward and away from the feed-table 27, which is suitably supported upon the frame of the machine, the extent of 1 the motion being understood from Figs. 2, 3,

and 5.

Meshing with the gear 21 is a gear 28, carried upon the shaft 16, which also carries the tape-feed cylinder 29, around which passes thesheet-tape 30, which also passes around the roller 31, suitably supported with respect to the machine.

32 designates a gear carried by the tapefeed cylinder, which gear is in engagement with the belt or chain 33, which passes around the gear 34, supported on the sheetapron driving-gear 36, which is carried by the shaft 35, the latter being suitablymounted in the'frame of the machmegnndsaid gear 36 is in mesh with the gear 37',- carriedion the in suitable connection in proper position with respect thereto by 'means of an idler 43, so that when the chain sion, I

'ing, thus stopping the movement of the crank-shaft 8, so that when motion is imparted to the crank-shaft 8 it operates the gear 37 and the gears 34 and 36, driving the shaft 35 when connected therewith, as hereinafter explained, the gear 34 operating the chain 33 and imparting motion to the tapefeed cylinder 29, while the shaft 35 operates the sheet-carrying apron 42.

38 designa es a chain which passes around suitable gears carried on the shaft 35, so that motion is imparted to said chain 38, which also passes around the gears mounted on shaft 39, said shafts 35 and 39 carrying suitable apron- cylinders 40 and 41, around which pass the sheet-carrying apron 42, the same passing over the platen 14 and is held.

38 operates the cylinders 40 and 41 the apron is operated. In order to stop the movement of said a ron during the time of the impres- 'ave provided certain mechanism therefor, which consists of a sleeve 44, keyed or otherwise secured to the shaft 35. In the present instance I have shown the same secured by a pin 45, said sleeve having a sheetapron locking-cam 46 thereon, which thus rotates with the shaft. The gear 36 is mounted on said sleeve 44 and is loose thereon, and inorder to lock the same to said sleeve, and consequently the shaft 35, I employ a washer-disk 47 with a suitable spring 48 bearing thereagainst and also against the locking-nuts 49, which are mounted on the threaded end 50 of said sleeve, whereby it will be seen'that the said gear 36 is locked to the shaft by means of friction, and when motion is imparted to'the gear 36, as before stated, by the crank-gear 37 the shaft 35 is rotated, and consequently the belt or chain 38 and the carrying-apron 42, so that as the sheet is fed down it is brought forward by the sheet-ta e 30 upon the sheet-carrying apron 42. s it is necessary to arrest the movement of the carrying-a ron, I employ a locking-lever 51, one end 0 which travels on the cam 46 and the other end of which is provided with a roller 52, which is in contact with the sheet-carrying apron stop-cam 53, suitably mounted upon the crank-shaft 8 and moves therewith, the said cam 53 being so timed as to permit the end of the lockinglever 51 to contact with the shoulder 54 of the locking-cam 46, which being keyed to the shaft 35 arrests the movement thereof, overcoming the tension of the spring 48, so that while motion is still imparted to the gears 36 and 34 the shaft 35 is prevented from rotatsheet-carrying apron 42, it being understood, of course, that the type-bed 12 is so timed as to make an impression at t e time that beneath the lowermost sheet,

the paper is held stationary. 'lhe sheet-carrymg apron stop-cam 53 continu ng its} movement will bring the nose thereof into i. levers 75 contact with the roller 52, as best seen in Fig. 2, and raises the same, thus releasing the shoulder 54, so that by means of the friction of the gear 36 motion is imparted to the shaft 35.

56 designates a suction-pump which is suitably actuated by the eccentric 57 ,carried on the crank-shaft, and is connected by a pipe 58 to the passage 18 in the shaft 17, the said action of the pump being such as to create suction at the air-passe cs 22 in order to draw down the lowermost o the sheets .59,

as best seen in Fig. 5, at the proper time,

said pipe 58-having a flexible connection 60 2 intermediate its length in order to permit of the rocking movement to the feed-gripper cylinder 20.

61 designates. a hopper or receptacle for the sheets or paper, the walls of the hopper being inclined r'earwardly from the feedopening, so that the sheets therein are held horizontal; but each sheet is slightly in advance of the sheet above, thus removing the weight of the sheets from the feeding-point and allowing the removal of the lowermost sheet with more ease. When a sheet is being removed, it is necessary to support at the feeding side of the hopper the next sheet, so that I provide a sheet-abutment 62, which consists of a suitable device adapted to pass beneath the paper and at the same timev against the front end of the pile of sheets and which is supported by the carrier 63, movable in a suitable guide 64, connected with the frame of the machine, saidabutment carrier 63 having suitable connection with an arm '65, pivotally connected with the sheet-abutment shaft 66, which also carries the actuatin -arm 67, the latter communicating with a suitable actuating-cam 68, mounted or connected with the tape-feed cylinder 29, so that as the latter is rotated the cam operates the actuating-arm in order to impart reciprocating motion to the carrier 63 in order that at the proper time the sheet-abutment is placed as before stated. The upper part of, the abutment has an angle-piece to conform to the angle of the pile of sheets.

In order to direct the sheets to their proper position, I provide the side guides 69, which are carried by the rods 70, mounted in the frame of the machine, and upon which rods the side guides may be clamped and adjusted,

said side guides'having a suitable grooveor passage 71 for the reception ofthe, paper or sheet, it being seen that the paper is fed down from the tapes 30 to the sheet-carrying apron 42 into the side guides, and in order to stop the same at the proper point above the platen I provide sheet-stops 72, which are mounted upon the rock-shaft 73., the same being spring-actuated, if desired, and carried in a suitable lug 74. said rock-shaft 73 having thereon for operating the same,

which are adapted to be engaged at the proper time by the plate 76, carried by the shaft 77, suitably mounted in the frame of the machine, said shaft 77 also carrying the operating-lever 78, which is in engagement with a cam'79 for operating the arm, said cam being carried and locked in suitable accord with the tape-feed cylinder 29, it being seen that thesaid plate? 6 is caused to hold or depress the lever 75, carried on the shaft 73, in order to raise the sheet-stop 72 and permit forward movement of the sheet or leaf at the proper time.

The operation is as follows: Power being imparted to the drive-pulley 4 causes the drive-shaft to rotate and imparts motion to the pinion 6 and to the main drive-gear" 7. This in turn actuates the bed-crank or separating-cam 9, the cam'57 for operating the suction-pump, the gear 37, and the sheetcarrying apron stop-cam 53. stated, thebed-crank 9 operates the connecting-arm 10 to impart a reciprocating motion thereto in order to move the type-bed 12 to and from the platen. In order to'feed a sheet to theposition above the platen, the separator-lever 15 is so" timed as to place the feed gripper cylinder adjacent the lower most sheet, the suction-pump 56 being operated in order to cause the suction and draw down the lowermost sheet at the same time the sheet-abutment carrier 63 is actuated forward to pass beneath and abut against the sheets while the feed-gripper cylinder ismoving away from the feed-table 27, as best understood from Fig. 5, the same being accomplished by suitable movements of the lever 15. At the same time the cam actuates the gripper 2.6 and causes the same to engage with the sheet, as seen in Fig. 5, the motion being imparted to the feed-gripper cylinder through the gear 21 and gear 28, the paper is brought around said cylinder 20 and is released by the gripper and passes along with the sheet-tapes 30, to which motion is also imparted, the saidsheet passing between the side guides 69 and upon the apron 42 until itassumes the proper position upon the platen beneath the type-bed 12, it having comein contact with the sheet-stop 72. The type-bed is now actuated to make an impression; but in order to arrest the movement of the apron at the same time the end of the locking-lever. '51 comes in contact with the shoulder 54 of the apron-carrier cam 46, as described, thus arresting the movement of the shaft and preventing movement of the apron until the impression has been taken, after whichthe o eration as above described is repeated, it 0' course being understood that the sheet-abutments are reciprocated back and forward at the proper time and that .the suction-pump is caused to create a suction to draw down the lowermost sheet, whichwill immediately be engaged As already drive-gear suitably actuated and by the gripper, and that after the impression is taken the plate 76 is operated in order to raise the stop 72 at the same time that the movement of the sheet-carrying apron 42 is started in order that the sheet can be removed from the press and another one fed to its place to receive the same.

It will be evident that various changes may be made by those skilled in the art which may come within the scope of my invention, 7 and I do not, therefore, desire to be limited in every instance to the exact construction herein shown and described.
