. anism for such bundling-presses, whereby the power is thrown out and the action of the press is arrested when the compression has reached a certain predetermined degree.

My improvements are particularly applicable to a double bundling-press in which two bundles of sheets or signatures can be simultaneously compressed;. but my improvements may be applied effectively to a single bundling-press.

My invention consists of novel features of construction and combinations of elements for eflectively accomplishing the desired results, and in order that my invention may be fully understood I will first describe the same with reference to the accompanying drawings and afterward point out the novelty more particularly in the annexed claims.

In said drawings, Figure 1 is a plan View, on a large scale, of a double bundling-press embodying my improvements, parts being broken away. Fig. 2 is a side elevation of the same on a smaller scale. Fig. 3 is an end View of the same. verse sectional elevation taken on the line X X of Fig. 2 and looking in the direction indicated by the arrows, said view showing parts of the automatic tripping device. Fig. 5 is a face view of one of the compressionheads. Fig. 6 is an edge view of the same.

The framework of my improved bundlingpress may be of any suitable form and construction to properly support the operative parts of the mechanism. In constructing a double bundling-press such as shown in the drawings and hereinafter described I prefer to form the frame of three uprights 10, 11,

i and 12, suitably braced adjacent to their lower ends by tie-

rods

13 and 14. An end view of the frame or upright 10 is shown in Fig. 3, and it will be understood that the otheruprights 11 and 12 are of substantially the same form, differing slightly in the shape Fig. 4 is a detail trans-- of their upper ends to adapt them to support the bundling-troughs, as indicated in Fig. 4.

The frame-pieces 10 and 11 are braced at the top by the brackets or pillow-blocks 15, in which the main power-shaft 16 is suitably journaled. Power-shaft 16 carries upon one end fly-wheel 17 and band-pulley 18, by which the press is operated. This power-shaft 16 also carries suitable gears and clutches for connecting it with the compression-screw, as hereinafter explained.

Supported between the uprights 11 and 12 at their upper ends are two parallel bundlingtroughs, each trough being formed of a series of parallel rods or

bars

20 or 21, said rods or bars being rigidly secured at their ends in any suitable manner to the frame parts so as to form a rigid structure, including the two bundling-troughs. The bars 20 form one of the troughs and the bars 21 the other.

Arranged directly beneath each of the troughs is a square track-

bar

22 or 23, ex-

tending parallel with the trough-bars and.

serving the purpose of assisting in support? ing and steadying the compression-heads of both of the bundling-troughs.

Each trough is provided with two compression-heads 25 26 and 25 26, between which the sheets or signatures are compressed by the action of the machine. pression-head is formed in its compressionface with the

intersecting slots

27 and 27, which expand interiorly into circular enlargements to facilitate the operation of passing the binding-cords around the bundles. The compression-heads are also each formed with grooves 28 in their edges to fit upon the trough rods or bars 20 21 and with integral downwardly-projecting ribs or flanges 29. The rib or flange 29 of each compression-head rests upon the upper face of one of the trackbars 22 23, so as to assist in supporting the trough-head in its angular position in the trough and at the same time provide a guide along which the rib or flange slides when the compression-head is moved.

; The compression-

heads

25 and 25, arranged one in each ofxthe bundling-troughs, are independent of each other. These

heads

25 and 25 rest normally against compressionsprings 30, which are supported in holes or pockets 31, drilled into the inner face of the frame-upright 11. Rods or bolts 25 project from the heads 25 25 through openings in the upright 1 1 and have nuts on their ends to confine the heads in position. Thevsprings. a

normally support the compression-

heads

25 and 25 a slight distance away from the face of the upright 11, the springs being of sufficient strength to withstand the degree of compression which it is desired to apply to the bundles placed under compression. When the limit of the strength of the springs is reached in the compressing operation of the machine, said springs will yield and be compressed, so as to allow the

heads

25 and 25 to independently approach the face of the upright 11, with the result that either one or bothof said heads will actuate the tripping mechanism for disconnecting the power and stopping the compression of the bundles. This tripping mechanism will hereinafter be fully explained.

The other of the compression-

heads

26 and 26,, which may be called the traveling compression-heads, are united into an integral rigid structure by means of a bridging portion 35, which extends between the two heads, as shown in Fig. 1 of the drawings. This bridging portion connects adjacent corners of the

heads

26 and 26, forming, in effect, .a compound head, the two portions of which are adapted to operate in unison to compress the bundles in both troughs simultaneously.

is the compression-screw, which is suitably journaled adjacent to its opposite ends in bearings formed in the upper parts of the frame-uprights 11 and 12, one bearing being This comshown at 41 and the other at 42. pression-screw 40 is threaded through a suitable nut 43, rigidly secured in the suitable opening extending through the bridging or connectingportion 35 of the connected compression-heads, so that the rotation of the screw willcause the two traveling compression-heads to move in the parallel troughs as a single structure.

Within the bearing 42 of the upright 11 the screw 40 is provided with a thrust-bearing collar 45, which is shrunk or otherwise securely fastened to the screw, so as to rotate with the screw in the bearing-socket of the frame. A capping-plate 46 of ring form surrounds the screw 40 and is securely fastened within the recess 47 against the inner face of the upright 11 by means of bolts 48, so as to securely confine the thrust-bearing collar in its bearing-socket, and thereby efi ectively prevent the longitudinal displacement of the screw 40.

50 is a bevel-gear keyed to the power end of the screw 40.. This gear 50 is in constant mesh with two similar bevel-

gears

51 and 52, which are loosely journaled upon the powershaft 16, above referred to, each

gear

51 and 52 being arranged adjacent to one of the shaft-bearings 15.

Combined with each of theloosely-mount- I ed gears 51 and 52 is a friction band-clutch of ordinary construction, the

rim portion

53 or 54 of each clutch being formed integral with or rigidly attached to one of the gearwheels, while the expansible band portion of each clutch is keyed to the power-shaft and carries the usual pivoted rock-arm 55, which is adapted to be engaged by one of the conical ends of the double clutch-spool 56. This clutch-spool 56 is suitably mounted upon the power-shaft 16 and is capable of sliding longitudinally upon said shaft in either direction to actuate either clutch so as to lock either of the bevel-

gears

51 or 52 upon the powershaft. This double clutch-spool 56 is formed with an annular groove 57, (indicated by dotted lines in Fig. 3,) in which engages the forked lower end of the actuating-arm 58, said arm 58 having an offset 59 formed with atransvers'e cylindrical socket whichfits upon a supporting-rod 60. The sockete'd offset 59 is securely fastened upon the rod 60, so as to move with said rod. The rod 60 is mounted to slide in bearings 61, formed in the upper ends of bracket-arms 62, which project up from the pillow-blocks 15. The portions of the rod 60 adjacent to its ends which slide in bearings 61 are provided with splines or feathers 63, which operate infea-ther-grooves within the bearings to prevent the rotary shifting of the rod and to allow the longitudinal shifting of the rod to carry the clutch spool in either direction.

Surrounding the rod 60 between the offset 59 of the spool-actuating fork and each of the bearings 61 is an expansion spiral spring 64, which springs tend to resist the movement of rod 60 and of the connected actuating-fork, in either direction and serve the purpose of returning said parts to their central inactive position for maintaining both clutches in dis engaged condition, normally allowing both

loose gears

51 and 52 to remain at rest upon the rotating powershaft. 65 is a hand-lever j ournaled at 66 upon the upper end ofan upright bracket 67, which is secured to the upper edge of the frame-upright 10. This handlever 65 has a short longitudinal slot 68, into which projects the pin 69, formed upon the upper end of the spool-actuating fork-arm 58. By means of the hand-lever 65 the spool 56 can be shifted in either direction against the action of one of the compression-springs 64.

Mounted upon the projecting end of the rod 60 at the left of the press isa-collar or tappet 7 O, which is adapted to coact with the latch of the automatic tripping -mechanism, presently to be described, for the purpose of holding the clutch-operating mechanism in either of its shifted positions until released I 'by the action of the machine.

The automatic tripping mechanism will now be described. 75 is a latching-lever .mounted upon a short shaft' 76, journaled upon a'bracket 77 at the left-hand side of the machine. This latching-lever 75 has a han dle portion 75 formed at its upper end, so

as to afford convenient means for its manual operation toreleasethe mechanism in case of necessity. Depending from the short shaft 76 is a rock-arm 7 8 ,Lcarrying at its lowerend a pin .79, which engages in an annular groove formed in a tappet-collar 81, secured to the projecting end of a tripping-rod 82. Tripping-rod 82 passes freely through an opening in the central'frame-upright 11 and extends to the rear of the machine adjacent to the endupright 12.. Secured .to the end of the tripping-rod 82 is a tappet-nut 83. Bolted to the rearface of the traveling compressionhead- 26 is a downwardlyrojecting forked tappet-plate 83", arrange to straddle the tr1pping-rod'82, so that when the compressionehead' 26 reaches the end of its return stroke .after compressing the bundle said forkedtappet-plate 83" will engage the tappet-nut'83 and'move'the rod 82 rearwardly to actuate the latching-lever, as hereinafter explained. Between the tappet-collar 81 and the frame-upright 11. an expansion spiral spring 84 is confined on the rod 82, so as to give said rod a normal spring tendency to move forwardly and cause latching-lever 75 to move upwardly into engagement with tappet collar 70. The latchinglever 75 is formed with an arm or offset 85, to which is pivoted at 86 a thrust-arm 87, formed with a downwardly-projecting portion 88, terminating in a cylindrical collar 89, mounted upon a trip-rod 90. The collar 89 is confined upon rod 90 by means of nuts 91. Trip-rod 90 passes freely through a suitable opening formed in the upper abutment portion of the central frame-u right 11, its inner end projecting slightly beyond the face of the abutment in the path of the compression-head 25, so that in the operation of compressing a bundle the movement of head 25 toward its abutment will engage the trip-rod 90 and force it rearwardly, causing the latching-lever 75 to be disengaged from the tappet upon rod 60.

The tripping mechanism so far described is suitable for a bundling-press having a single bundling-trough. It will be clear that in a double bundling-press it is impracticable to quickly supply exactly the same uantity of sheets or signatures to both of t e bundling-troughs, so that it' is desirable to provide an additional tripping device for controlling the throW-out from the second bundlingpressthat is, two independent tripping devices, one actuated by each of the bundles being formed. In my improved machinejI provide such independent tripping devices in the mannerin whichIwill now explain Extending across the machine is a rock-shaft 95, journaled at its ends in suitable brackets 96, securedto the top of the central frame-upright 11. This rock-shaft 95 carries at one end a depending rock-arm 97, which rests behind pin 98, projecting latthe opposite end of the rock-shaft 95 is a depending rock-arm 99, carrying an eyebolt .100, which is confined upon a trip-rod 101 by means of suitable nuts. The tappet-rod 101 projects through the abutment portions of the frame-upright 1.1 into the path of the compression-head .25, with the result that when the bundle is bein compressed against the head 25 reaches the desired degree of compression the springs 30, sustaining said head, will yield and allow the head to engage the trip-rod 101 to cause it to rock the shaft 95, with the result that the latching-lever will be actuated to release the clutch. By this means I provide a double bundling-press with a tripping device actuated by the thicker of the two bundles being formed.

The operation of the machine will be clear from the brief description following. The

power-shaft is continually rotated, the,

clutch-spool being normally in central disengaged position to allow both

gears

51 and 52 to remain at rest. Under these conditions the compression-screw is also at rest. The compression-heads being in their separated position, the two troughs are filled With sheets or signatures that are to be compressed into bundles. A sufiicient quantity of sheets or signatures are placed in each trough to practically fill the space between the compression-heads. The hand-lever 65 is then pushed to the right for locking the gear 51 upon the power-shaft, with the result that compression-screw 40 'will be rotated to move the

heads

26 and 26 forward in the parallel troughs. It will be observed that in the position of the parts shown in Fig. 2 the latching-lever 75 is held-away from the latching-tappet 70 by reason of the engagement of the tappet-plate 83 with the tappetnut 83. In starting the machine it is necessary for the operator to hold onto the starting-lever 65 for an instant to allow head 26 to move tappet-plate 83 from engagement with nut 83, which. disengagement releases the tripping-rod 82 and its spring 84, moves it forwardly, and causes the latching-lever 75 to engage the outer end or face of the tappet 7 O. The result of this engagement is the locking of the operating mechanism in shifted position.

hold upon the lever 65. The compression screw 40 will continue to rotate and force the connected heads 26 and 26 toward the compression-

heads

25 and 25 until one of the

heads

25 or 25 is forced inwardly against the abutment of upright 1.1, overcomingthe resistance of springs 30 and actuating one of the trip-

rods

90 or 101 for forcing the latching-lever 75 out of engagement with the tappet 7 0. The moment lever 75 is disengaged from tappet 70 the right hand spring 64 will force rod 60 and connected spool v56 to the left for releasing the bevel-gear 51 from the The operator may then release his power shatt and ar'resting the advancing action of the compression-screw. The operator then ties the bundles by passing cords around them through the armholes of the compressioneheads in the well-known man As soon as the bundles have been ver'7'5 engagesth'e inner-face of tappet for holding the operating mechanism in its lefthand shiftedxposition. As soon as the latch isengaged the operator may release hishold on the lever, andthe compression-screw will continue to rotate 1n'1ts reversedlrection to cause the connected heads 26 and 26 to re.

turn to. their normal positions, it beingund erstood that when the connected heads reach their return positionthe-tappet 83 willengage. the tappetenut 83 and shift the tripping rod 82 to againdisengage the latching-lever fromthe tappet 7 O to-allowthe left-hand spring 64 to return the clutch-operating parts to their normalicentral inoperative position. The machine is then-ready for a repeti tion of. the described operation.

:It will be observedthat the clutch which locksithe gear 52 to the power-shaft isbroader and stronger than the corresponding clutch, which looks gear 51 .to the powershaft. This is for the purpose of insuring sufiicient power for releasing the compression-heads after the'bundles have been. compressed.
