CELL-CASE MACHINE.

SPECIFICATION forming' part 0f Letters Patent No. 667,287, dated February 5, 1 901.

Application filed November 27, 1899. Serial No. 738,277. (No model.)

T0 @ZZ whom t may concern:

Beit known that I, JAMES H. BATCHELDER, a citizen of the United States, residing at Tama, in the county of Tama and State of Iowa, have invented certain new and useful Improvements in Cell-Case Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same..

This invention relates to that type of automatic machines for making and interlocking the strawboard strips for egg-cell cases in which the respective strips are punched by a pair of punch-heads, one on each side of the machine, the severed strips are carried by suitable holders from the initial punch to the top of the machine, Where the strip-carrier is turned ninety degrees, the cross-strips are at the other punch-head interlocked with the initial series and cut off, and the completed cell-case is finally discharged at the bottom of the machine.

This invention has for its obj ect to improve the feed mechanism, the vmechanism for turning the strip-carriers one quarter of a revolution, the carrier-actuatin g mechanism, the cell-case ejector, and other details in a machine of this type, as Will fully appear from the description and claims following, y reference being had to the accompanying drawings, in Which- Figure l is a general View in perspective of a machine embodying my improvements. Fig. 2 is a similar view of the same as seen from the otherside. Fig. 3, Sheet 2, is alarger view of the upper part of the machine as shown in Fig. 2, but from a more elevated point of View. Fig. 4 is a fragmentary perspective view showing parts near the base of the machine on the side opposite to Fig. 3. Fig. 5, Sheet 3, is a central section of the machine longitudinal to the base. Fig. 6 illusarm connecting With the slapperor strip bottoming device. Fig. 7, Sheet 4, is a rear elevation showing one of the stri p-carrier trucks and its connection with another. Fig. 8 is a front view of one of the strip-carriers. Fig. 9 is acentral section of the same and its truck.

Fig. 10 is an ideal plan View of the quarterturn mechanism.

Similar characters 0f reference indicate corresponding parts.

In its main features the machine has the characteristics of the machine describedin. Patent No. 619,267, issued to me on the 14th day of February, 1899; but in the present invention instead of cutting simultaneously the Whole number of strips in the cell-case the machine cuts but two at a time. Other changes in construction and novel features will appear in the description and claims following.

On a suitable base Aare mounted four standards B, connected at their upper ends by bridges C. These standards and bridges are provided with suitable bearings E forguiderods F, to Which are secured the punch-heads F', provided With suitable punches F2 and a shear -blade F3 to sever the punch-strip. These coact With dies F4, attached to a table F5, suitably secured to the standards. On this table are mounted the feed-rolls G, to which an intermittent motion is given by an oscillating disk G', carrying a pawl G2, engaging a ratchet G3 on one of the roll-shafts.

A regular reciprocating movement is imparted to the punch-heads by connectingarms H, coupled to cranks H on cross-shafts H2. These shafts are provided with bevelgears H2, engaging pinions H1, secured to a shaft H5, journaled in bearings B' and B2 and provided With a suitable drive-pulley H6. On one of these shafts H2 is mounted a cam G4, which engages a roll G5 on a reciprocating arm G6., pivoted on a stud GT at the side of the machine. The free end of this arm connects by a link G8 With a disk G9, secured to a rock-shaft G10, journaled in bearings G11. From cranks G12 the oscillating motion of the vdisk is transmitted to the feed-rolf disks through the medium of con necting-rods G111 and G14, as clearly indicated in Figs. 1 and 4.

A furtherimprovement in the feed mechanism is shown in Figs. 4 and 5. The cam G4 is similar to that shown in Fig. 6 to give a very quick return to the feed-pawls, as the time for this feed is limited, being only about onefifth of a revolution of the main crank-shafts.

IOC

' B3 at each inner side of the machine.

This quick return of the pawl and actuating mechanism when running at as high a speed as is desired would prod nce a very detrimental jar if no provision were made for cushioning the stroke. This is done by means of a dash* pot G15, whose piston Glconnects with a crank G17 on the rock-shaft G10. This dash-pot is of a simple and well-known type and need not be particularly described. The return movements of the feed mechanism are caused by a powerful spring G48, one end of which connects at some suitable point to the frame of the machine and the other end with a crank-pin Gwon the said rock-shaft, as shown in Figs. 2 and 3. By this means the necessary quick action of the feed is secured without injurious vibration.

In common with the machine described in my former patent a series of carriers I are employed to receive the cell-case strips between -their holding-fingers I' and convey them from the points where the strips are so received to the point of ejection. In the case of both the primary strips cut from the strawboard sheets l (part of a roll of strawboard not shown) and the cross-strips cut from the sheet 2 at the opposite side of the machine the most of the strip is fed between the holding-fingers before being cut off. The carrier-fingers are attached to a rectangular table I2, centrally pivoted on a truck I3, having four wheels I4, traveling in an oblong circular-ended track The detail of the carrier is best shown in Figs. 7, S, and 9. In each end of the truck-frame I3 is secured an axle I5, and on the outer ends of these axles are mounted the wheels I4. vBetween the wheels and the truck-frame are links I6 of exact and uniform length, connecting each pair of trucks in the whole series, the number in this machine being ten. By :reference to Fig. 5 it will be seen that when any two of the carriers are in the same plane their adjoining` edges lie close together and the spacing of the fingers from one to auother is uniform with the spacing on each separate carrier, so that through the whole circuit of the carriers their intermittent forward movement is exactly uniform. Near each side of the truck-frame is a pair of ribs I7, and between these is mounted at each side and at the longitudinal center an antifriction-roll I8, adapted to engage a sprocketwheel J, coinciding therewith and secured to a cross-shaft Jl near the upper end of the machine. The use of a sprocket at each side of the carriers insures perfect steadiness in the movement of the carriers and prevents the possibility of theirgetting out of alinejoining reversed ratchetJ3 being also pro-- vided to prevent any backlash. On the projecting portion of the shaft is pivoted an arm J4, and near one end of this is mounted a pawl J5 to engage the ratchet J2. To the adjacent end of the arm is connected a rod J6, the other end of which couples to a crank J7 on one of a pair of elliptical gears J8, attached to a cross-shaft J9. This gear meshes with a similar gear J10 on the shaft H2, the purpose of the elliptical gearing being to give a relatively slow forward movement to the carriers with a quick return of the actuating mechanism. To the other end of the arm J4 is connected a link J, coupled at the lower end to a pivoted pawl J12, adapted to engage the teeth of the ratchetwheel J 3. These pawls are so adjusted with respect to each other that the pawl J3 engages a new tooth on the reversed ratchet at the extreme limit of the movement of the other pawl forward, and thus serve as a positive stop to any further forward movement of the train of carriers due to their own momentum. By placing the ratchet-s side hy side instead of on opposite sides of the machine this feed mechanism has been materially simplified and improved, as the stop-pawl is now connected with the same arm as the feed-pawl.

In Fig. 3 the quarter-turning device is shown in action, and Fig. l0 is an illustrative plan of the same.

K is an arm pivoted to some suitable part of the main frame at the top. A spring K' is mounted on the stem of a fork K2, hinged to the arm, and its other end abuts on a shoulder K3, which serves as a guide for the fork. At the free end of the arm is a roller K4, adapted to pass between two connected carriers, and in making the turn over the semicircular part of the track they gap apart, as shown in Figs. 3 and 5. It is to be understood that at the upper end of the track there is space for the carrier to turn around in; but as it passes to the vertical part of the track it is held in alinement by the adjacent track, this feature being shown in theformer patent above referred to. The action of the device will now be apparent. In Fig. lO the lower of the carriers is supposed to be prevented from further turning by the adjacent tracks. As soon as this carrier has passed below the roller K4 the latter automatically swings inwardly between it and the one following. The roller then engages the corner of the succeeding carrier, and as it advances it is turned one-fourth of a revolution, when it in turn enters the space occupied by the lower carrier and is held from further tnrning. structure, but the action is very easy and smooth, occupying, as it does, the time required to feed the train of carriers forward half the length of one of themthat is to say, seven revolutions of the present machine.

Below the table which supplies the crossstrips to complete the cell-case is mounted a slapper M, connecting with a rock-shaft M' by The device is not only very simple in` IOO arms M2. Adepending arm lVI3,provided with a roller M4, is also attached to the rock-shaft, and the roller travels on the periphery of a cam M5, attached to the cross-shaft J9. To another arm M6 is connected a spring M7, secured at the other end to the machine-frame. This spring gives the forward or inward impulse to the slapper as soon as the roller passes the highest point of the cam, which is supposed to turn in the direction indicated by the arrow in Fig. 6. The slapper-plate spans two parallel strips, and as it acts at each revolution of the machine each strip in the carrier receives two blows, whereby all are perfectly bottomed in the carriers and interlocked.

The mechanism for ejecting the finished cell-case is best illustrated in Figs. 5, 7, 8, and 9. On the outer face of each carrier-table is mounted a stripperplate N, having a central axle N', which for the sake of lightness is made tubular, passing through the central hub of the carrier. To the inner end of this axle is secured a cross N2, with a roller N3 mounted on each arm. Near the lower end of the machine a pair of cam-plates N4 are secured to a bridge N5, fixed to the main frame. The channels N6 of these cams form paths for a pair of the rollers however the carriers may be turned. These channels are coincident with the normal positions of the rollers at their upper ends, but curve downwardly until at their lowest point, corresponding practically with the middle of the m achine,they thrust the strip per-plate downwardly nearly the full length of the carrierngers. The eect is of course to eject the finished cell-case, and the action is performed very gradually without any shock whatever, and by the use of a broad flat surface bearing against the edges of the strips. There is thus no possibility of injury to the completed cell-case, which drops gently and of its own weight on the open space made to receive it in the middle of the machine-base. Hitherto much of the trouble in the operation of a cell-case machine has been due to the ejector, which by the suddenness of its action and its limited surface exposed to the cell-case has tended to break the cell-case more or less. The injury to the particular cell-case was not so serious as the leaving of pieces of strawboard lodged between the carrier-fingers to obstruct the succeeding strip, whereby the carrier would become clogged and the machine would need to be stopped andthe obstruction removed. This difficulty is entirely removed by the ejector above described.

The efficiency of this machine is due in no little measure to the fact that the punching and cutting are done .by both punchheads simultaneously, instead of alternately, asin my former machines. This construction allows more time for the operation of the strawlboard and carrier feeds and the action of the bottomer, and thu's admits of a relative increase in the speed of the machine.

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