Specification of Letters Patent.

Patented June 4, 1912.

Application filed January 19, 1910. Serial No. 538,928.

To an whom it may concern.

Be it known that I, (ilCOIlGltfF. MoAimirs, a citizen of the United States, and resident of the borough of Brooklyn, in the city and Stateof New York, have invented a new and useful Paper Cutting, Ruling, and Assembling Machine for Making Tablets, of which the following is a specification.

My invention relates to a paper feeding, cutting, ruling and assembling machine for making tablets, the object being to provide a machine of the above character which shall perform its work in an effective and expeditious manner.

A practical embodiment of my invention is represented in the accompanying drawings, in which,

Figures 1 and 2 taken collectively, represent a top plan view of the machine as a. whole; Figs. 3 and 4 taken collectively, represent a view of the same in side elevation, showing in dotted lines the position of certain parts when lifted to gain access to other parts; Figs. 5 and 6 taken collectively, show a vertical central section of the machine; Fig. 7 represents in detail the arrangement of the change gear for varying the number of sheets between consecutive inserts; Fig. 8 is a partial plan view in detail, showing the means for preventing the sheets of paper from folding as they pass from the delivery mechanism to the receiving table or lay-boy; Fig. 9 is a transverse section taken in the plane of the line A-A of Fig. 8; Fig. 10 is a view in detail showin the arrangement of gears for automatically lowering the receiving table or lay-boy as the sheets accumulate thereon, for jo ging the sheets into alinement and for acce crating the speed of the sheet as it approaches the point of delivery, and Fig. 11 is a detail transverse section in the plane of the line B, Fig. 6, showing the action of the delivery rolls on the inserts.

The machine consists of three principal parts, to wit: the sheet cutting mechanism, the sheet ruling mechanism and the sheet delivering and assembling mechanism; and while my invention is for the greater part directed toward the sheet delivering and assembling mechanism, the three principal parts above named co-act so intimately one with another that it will be necessary to trace certain motions of the delivering and assembling mechanismsback to the mechanisms for cutting and ruling. r

The paper to be cut, ruled and assembled is drawn from a supply roll 1, andis cut at the point. 2 into sheets which are received between endless carriers 3 and 4 and advanced to the ruling mechanism, indicated as a whole by 5, and thence pass along-between endless carriers 6 and 7 to the delivcring mechanism composed of endless carriers 8 and 9, from which they are delivered on to a receiving table, or lay-boy as it called, 10.

The several endless carriers above referred to consist conveniently of cords arranged at suitable intervals to support the sheet, the lower endless carriers 4, 7 and 9 being relied upon to advance the sheets while the upper endless carriers 3, 6 and 8 serve to hold the sheet in a flat position on the lower carriers, bearing lightly upon the sheets and having but little effect in advancing them farther than what is due to such light frictional bearing as may be incidental to holding them in position. This is called attention to at this point in view of the accelerated motion imparted to the lower endless carriers, particularly the carrier 9, at the delivery end of the machine, as will hereinafter appear more in detail. The carrier 3 is driven by frictional contact with a roll 11 positively actuated by a belt 12 engaged with a pulley 13 on the drive shaft 14 and with a pulley 15 on the end of the axle of the roll 11. The endless carrier 4 is driven by a roll 16, (see Figs. 1 and 5) actuated by a belt 17 engaged with a pulley 18 on the axle of the roll 16, and with a pulley 19 on a shaft 20, the shaft 20 being driven by a belt 21 engaged with a pulley 22 on the drive shaft 14, and with a ulley 23 on the shaft 20. The shaft 20 aso imparts motion by means of suitable gear, to the ruling mechanism, denoted as a whole by 5, which forms specifically no part of my present invention. The endless carriers 6 and 8 are driven by the frictional contact of the roll 24 with a roll 25, the latter being positively driven from the roll 26 by the endless carrier 9. The roll 26 is driven by a belt 27 passing around a pulley 28 on the axle 29 driven from the shaft 20 by a belt 30. The belt 27 engages a pulley 31 on the axle 32 of the roll 26, and also engages a pulley 33 on the shaft 34 mounted in suitable hearings in a bracket 35 depending from a portion of the machine sup orting frame 36. The belt 27 is given the esired tension by means of a tightening pulley 37 adjustably s'1p ported in the frame 36. The roll ou the axle 2t) hereinahove referred to, is denoted by SS and supports one end of and drives the lower endless carrier 7. The relation of the pulley 28 on the axle 29 to the pulley til on the axle 31 is such that the endless carrier t) is driven at a rate of speed faster than the endless carrier 7, so that the sheet of paper which is to be delivered on to the layboy is, immediately before its delivery, advaiiced away from the preceding sheet, leav ing a short interval between the delivery of two consecutive sheets.

The receiving table or lay-boy denoted as ahvholc by 1U, is removably supported upon narrow shoulders 39 and 40 at its opposite edges, said shoulc'lers being conveniently formed by means of angle-iron pieces, which iieces are secured to vertically movable slides 41 and 49, arranged to slide up and down in vertical ways 43 and 4,4 uprising from a base a5 locked together near their upper ends by a cross-tie 40. Fixed to the outer faces of these vertical ways 43, 44, are horizontal frame pieces 47, 48, the said frame pieces serving to support reciprocating rods, in the present instance, a pair of rods at each end, the pair at one end being denoted by 49 and the pair at the opposite end by 50. These rods 49 and 50 support sideboards 51, .32, employed in jogging the sheets into register in a manner similar to that shown, described and claimed in my pending application Serial No. 501,369, filed June 10, 190.

The lowering of the receiving table or lay boy 10 is automatically accomplished at the desired intervals by the raising of an arm 53 as the sheets and inserts are deposited underneath it, as follows: The free end of the arm 53 rests lightly on the pile of sheets, the arm itself being fulcrunied at 54 to a rearwardly uprising portion 55 of the frame 36. A short arm 56 (see Fig. (3), fixed to rock with the arm 53, has its free end'in position to engage a tail piece 57 on a pawl 58, the latter being pivoted to a rocking plate 59 mounted loosely on the shaft (30 of a ratchet wheel 61. This shaft (50 is journaled in suitable hearings in the uprising frame piece 55. The shaft G0 also carries a bevel gear pinion (32 which engages a bevel gear pinion (33 on the shaft 4 mounted in a suitable support on the frame piece 55 and also in a suitable bearing on the upright way 43. The shaft M has on its opposite end a worm which enga es a worm wheel (l6 carrying a pinion 6a engaged with a spur wheel 68 fixed to rotate with. a shaft (39 carrying two drums T0 and 71 on which are wound cords or chains 72, 73, extending from the said drums downwardly and around guide pulleys 74;, 75, attached to the base 4-5 and thence extending upwardly to and over guide uilleys 7t), 7?, supported in the up right ways "til, it, and thence down 'ardly to the lides 4t, 42, to which they areal tat-hell. A rocking plate 5'.) is ronm-rted by arod T5 with an ((t'tlll rir Til till the shaft 50 of a pulley hf] driven by a belt 82 leading to a pulley 83 on the shaft .20 hereimibove referred to. \Vheu the arm .125 is in its lowered lursltlfill. as at the beginning of a pile of sheets or the beginning of a section ot' a pile, the nose of the paul 3% will be out of engagement with the teeth on the ratchet wheel ti! and the rotary moveuwnt of the pulley H1 and eccentric 7?), which, through the rod 78 rocks the plate 5), will have no etlect upon. the ratchet wheel 01, but when the pile of sheets has accumulated to the desired height and an insert has been placed thereon, the arm will be lifted sufficiently to throw the nose of the pawl 58 into engagelnent with the ratchet wheel 61 and the rotary ITIOVOH'IGHtZ of the pulley 81 and eccentric 79, will, when it rocks the plate 59, advance the ratchet wheel and through the gears 62, 63, rotate the shafts (54 and hence the worm Ghand worm wheel 00, in a direction to unwind the lay-boy supporting cords or chains 72, 73, from their respective drums, thereby permitting the lay-boy 1.0 and its supporting slides 11, 4?, to drop a distance correspom'ling to the thickness of a section of the pile. Such drop will in turn lower the free end of the arm and thereby release the pawl 58 from the ratchet wheel (31 and arrest the downward movement of the lay-boy until another section of the pile has accumulated thereon, when the above descplibed action will again take place.

he mechanism for delivering the inserts at the proper intervals in the course of the piling of the sheets on the lay-boy, is accomplished as follows: The inserts, denoted by 84, are arranged in a pile on a forwardly and downwardly slanting table 85 supported at its forward end on the part 55 of the frame and at its rear end on the bracket 86 resting on the frame 36. At its forward end the said table 85 is provided with an abutment 87 between the lower edge of which and the top of the table 85, there is a slot 88 of a width corresponding to one of the inserts and so located as to permit the lowermost of the pile of inserts to be advanced freely therethrough, while those inserts above it are held against an advance movement by the abutment ST. The lowermost of the inserts is advanced by means of a push plate 89 having a thickness corresponding to the thickness of one of the inserts and extending across the rear end of the insert, the said push plate being provided at its opposite edges with slides 90, 91, (see Fig. 2), engaging the opposite edges of the table 95. This push plate 89 provided with a thin forwardly projecting lip 92 which gradually tapers to a thin edge as it extends umlerneath the pile of inserts'84, and which at all times rests throughout a greater or lesser extent of its surface underneath the rear end of the pile 84, in order to insure the bringing of the forward edge of the push plate 89 in direct contact with the rear edge of an insert when the insert is to be advanced. The push plate 89 is operated by a pair of rocking arms 98, 94, each pro vided near its upper end with an elongated slot 95 for receiving a pin 96 set in some one or more of the holes 97 in the outer faces. of the slides 90, 91. The arms 93, 94, are connected to rock together and are'fulcrumed on a cross-rod 98 supported from the frame 36. These arms 93, 94, are operated by means of a downward extension 99, the free end of which is arranged to ride over the surface of a snail cam 100, fixed to rotate with a ratchet wheel 101 mounted on a shaft 102 at the base of the frame 36. The ratchet toothed wheel 101 is advanced by means of a pawl 103 carried by a rocking arm 104 pivoted on the shaft 102 and connected by a rod 105 with the lower end of a vibrating lever 106 fulcrumed at 107 on the support 108. The lever 106 is operated by means of a pitman 109 connected with its u :iper end and leading to an eccentric 110, see Fig. 7) on the shaft 111 supported in the cutter frame 112. The shaft 111 is driven by an interchangeable spur wheel 113 in mesh with an intermedlate spur wheel 114, which, in turn, is engaged with a pinion 115 on the main drive shaft 14. The shaft 111 also carries the lower cutting drum 116 and a gear 113* which intermeshes with a gear 117 on the shaft 118 on which the upper cutting drum 119 is fixed. The intermediate gear 114 is mounted in a swin ing support 120 supported on the drive shaft 14, and as the gear 113 is changed to a gear larger or smaller than the gear shown, the swinging support 120 may be swung away from or toward the ears 113, and locked in position by means 0 the elongated curved slot 121 and a suit-able clamp screw 122 in any well known or approved manner. The rotary movement of the gear 113 and hence the shaft 111, operates the pitman 109 and hence the vibrating lever 106, and through the connection 105, the rocking arm 104, and advances the wheel 101 and the cam 102, the position shown in Fig. 6 being that position where the extension 99 is about to pass over the nose of the cam and fall inwardly, thereby permitting the arms 93, 94, connected wlth the push plate 89, to move forward under the tension of the s ring 123, (see Fig. 4), to force an insert orward into position between the insert delivery rolls 124 and 125. A retaining pawl 126 is employed to hold the ratchet toothed wheel 101 in its advanced position,

and the amount of advance movement of the ratchet wheel 101 for each revolution of the shaft 111 carrying the eccentric 110, is determined by the amount of throw which shall be given to the arm 104, that. is, whether it shall be given a throw suflicient to advance the wheel 101 one tooth, or whether it shall be given a throw sufficient to advance the wheel 101 two or more teeth. The amount of throw of the arm 101 is determined by adjusting the end of the connecting rod 105 along the lever 106, toward and away from its fulcrum 107, and is conveniently accom )lished by means of a clip 127, which may e clamped to the lever by a set screw 128 of well known or approved form. The pawl 103 is also made adjustable along the rocking arm 104 by means of an elongated slot 129 in which the pawl supporting pivot 130 is secured. The insert delivery roll 124, which preferably consists, as shown in Fig. 11, of disks located at a suit able interval apart on the axle 131, is positivel driven by means of a spur gear 132 on the axle 131, through the intermediate gear 133 engaged with the gear 134 on the axle 32 which as already shown, is driven by the belt 27. The pulley roll 125, which, in turn, is preferably composed of several disks, (see Fig. 11), particularly two, to register with the disks on the lower roll 124 and the intermediate disk, to give the insert a slight curve as indicated by the broken hair line, Fig. 11, is a gravity roll and rests on the insert, its axle or trunnions being allowed to move in the bearings sufliciently to allow the insert to pass between the rolls.

The jogging mechanism is operated by means of an eccentric 135 on the shaft 34 of the pulley 33, which eccentric is connected by a pitman 136 with the bracket 137 attached to the transvcrse abutment 138 at the rear of the pile of sheets. The chains 139 and 140 for operating the sideboards of the jogger are also connected with this bracket 137 and operated by it as it is reciprocated by the eccentric 135.

As the sheets are fed between the upper and lower carriers 8, 9, at the delivery end of the machine, they are given a curved form by means of slanting guides 141, 142, (see Figs. 8 and 9), the said guides being preferably convex toward the sheet in cross section, as clearly shown in Fig. 9, and gradually increasing in cross sectional area as they advance toward the deliver end of the machine. This curving of t e sheet gives it stren th to prevent it from folding under as it leaves the delivery rolls and shoots forward on to the pile, permitting it to drop readily convex side downward, on to the pile.

To permit the endless carriers to be lifted from their normal positions at a point immediately in advance of the ruling mechanism, as shown in dotted lines, Fig. 3, in order to gain ready access to the ruling mechanism for any purpose, I provide a hinge in the side rails of the frame at 143, and hold the several parts of the endless carriers in their respective positions by in troducing guide or retaining rolls 1414, 1 1 5 and 146.

14-7 represents a swinging support which may be utilized to hold the frame in its raised position. 1

The operation of the machine as a whole may "be briefly described as follows: The paper fed from the roll 1, after having been cut into sheets and passed to the ruling mechanism, leaves the ruling mechanism and travels along until it reaches the endless carriers 8 and 9, where the travel of the ad vance sheet is accelerated and it leaves the sheet next preceding and is given its curved form and pushed forward on to the pile where it is jogged into register with sheets which have previously fallen. After a sufficient number of sheets have accumulated, the number depending upon the rapidity with which the snail cam 100 is operated, an insert will be forced from the pile of inserts on to the pile of sheets, and this will lift the arm 53 sufiiciently to set in operation the lay-boy lowering mechanism and the latter will be lowered the thickness of one section of the pile, in practice the thickness of a tablet. When the pile on the lay-boy has reached the limit by the lay-boy having been lowered to its lowest feasible position, a truck, not shown, or any convenient carriage may be brought into position approximate to the pile and the pile moved on to it, a new receiving table or false bottom being placed on the supports 39 and 40 in position to receive a new pile of sheets and the receiving table or lay-boy raised to its uppermost limit, the machine having been stopped for this short interval during which the pile of assembled sheets is removed and a new receiving table placed in position.

It is intended that the interval between the delivery of two sheets shall be suflicient to permit an insert to be dropped in position and the parts are so timed that when an insert is to be placed in position, it will be pushed forward simultaneously with an advancing sheet and delivered under the arm 53 immediately after a sheet has been de livered with just suflicient clearance to prevent it from interfering wit-h the advance of a succeeding sheet.

What I claim is:
