MARTIN- L. KEYES, OF OARTHAGE, NEW YORK, ASSIGNOR TO FRANKLIN E. ROBINSON, OF SAME PLACE.

BU RIAL-CASE.

SPECIFICATION forming part of Letters Patent No. 655,560, dated August '7, 1900.

Application filed December 5,1899l Serial No. 739,321. (No model.)

To a/ZZ whom, it may concern.:

Be it known thatl, MARTIN L. KEYES, a citizen of the United States of America, and a resident of Carthage, Jefferson county, New York, have invented certain new and useful Improvements in Burial-Oase Machines, of which the following is a specification.

My invention relates to mechanism for turning a burial-case made from wood-pulp; and it consists in the mechanism hereinafter more fully pointed out and claimed.

The object of my invention is to furnish a mechanism for taking a burial-case as the same comes from the dies in a hydraulic press and properly supporting the top and vbottom and turning the same from its reverse position to its normal position, where the same can be safely transported to the ovens for evaporating and solidifying the fiber.

In the drawings, Figure 1 is a perspective view of my machine. Fig. 2 is a front view of the same, broken lines in both instances indicating parts removed. Fig. 3 is an end view of Figs. 1 and 2, taken from the left side of said figures. Fig. 4 is an end view of Fig. 1, taken from the left, showing the burial-case in its normal position. Fig. 5 is a vertical section showing the relative position of the parts. Fig. 6 represents details of construction of the locking mechanism for holding the mechanism in the position illustrated in Figs. l, 2, and 3. Fig. 7 is a side view of the fol-l lower and the cam, brokenlines indicating parts removed. Fig. 8 illustrates a section of the hydraulic press, the male portion of the die in the hydraulic plate being shown in cross-section and the hydraulic piston being shown in full lines, the movable portion of the device being shown in full lines to the right of the standard of the hydraulic press. Fig. 9 is the same view as Fig. 8, dotted lines indicating the position of the inverted burialcase. Fig. 10 illustrates a left-hand view of Fig. S, and Fig. l1 is a vertical section of Fig. 9 on line A B.

In the drawings similar characters refer to corresponding parts in the several views.

In the drawings, arepresents a portion of the frame of a hydraulic press, in which I make the body portion of burial-cases from wood-pulp.

a', Figs. 8 and 9, represents the perforated male die, mounted on plate a2, Figs. 8 and 9, supported and operated on hydraulic piston Theperforated male die a works inside of the female die. (Not shown in the press.) Both dies are vperforated for permitting the outflowy of the water Huid in the pulp. The two portions of die are brought into proper situation with reference to each other, and 6o the liquid pulp is placed between the dies under hydraulic pressure untilsufficient pulp is placed between the dies for making the required thickness, When the hydraulic pressure is applied and the fibrous portions of the pulp are compressed into the requisite shape approximately and into any thickness. Stripper 2, having spurs or projections 2 on its upL per surface, is placed over or around the male die a and rests on flange a, so that the edge of 7o the case is built in engagement with the spurs, the spurs or projections being embedded in the edge of the wall of the case, thereby pre; ventingthe case from moving, slipping, or sliding when the male die is withdrawn and the case is prepared to be moved out of the press. Vhen the male die is lowered out of the case in the operation of the hydraulic press, the stripper engages lugs or supports on the frame, which are not shown, and the male 8o die is withdrawn, leaving the stripper and the case thereon in position to be moved out of the press into the position Where it rests pre paratory to having its position'inverted, as hereinafter more `particularly pointed out.

The operations here enumerated are the ordinary operations of a pulp hydraulic press, and the parts illustrated will be readily understood, as they are not particularly claimed in this patent, but are simply partially illusgo trated to more fully understand the purposes and operations of the mechanisms, which I will now proceed to more fully describe.

The wood-pulp burial-case 1, formed in the hydraulic press, I place at the point where 95 the edges of the inverted burial-case rest at stripper 2, which consists in a frame constructed, preferably, of iron or steel'a'nd provided on its upper surface with a series of engaging points 2, Fig. l1. It should be borne roo in mind that the rib or ribs can be used inside of the projecting points over or against which sns vis run on antifriction-rollers 2b.

the inverted edge of the burial-case rests for from tipping or otherwise disarranging the preventing sliding or slipping when the burial-case is removed from the press to be transported to the drying-room. This stripper 2 (Hest illustrated in Figs. S and 9.) These antifrictionrollers are mounted in the press and are provided to facilitate the moving of the stripper and the burial-case out of the press and on frame 13, hereinafter more particularly pointed out. This stripper is used to free the wood pulp case from the male die, which moves into the -position shown in Figs. S and 9, leaving the burial-case on the stripper, so that it can be moved into the position shown in dotted lines in Fig. 9 for the purpose of turning the same off from the stripper into the-position shown in Fig. 4. Vhen this is accomplished, the stripper is swung back into the position shown in Fig. 8, where it can again be used. After the burial case is formed and the stripper containing the case is brought into the position shown in Figs. 1, 2, and 3 it is important to turn the burial-case from its inverted position to the reverse position (shownin Fig. 4) while it is in the green state, and to prevent the burial-case from slipping on the stripper while the reversing operation takes place it is important to hold the same, and for this purpose I employ points 21L on the stripper, Fig.'11; but a rib or ribs may be used in place of the points. In order to hold the case on the stripper while it is being reversed, I provide a wood rack or frame 3, made of slats, and place the same on the inverted bottom of the case. The slats in this rack are run lengthwise of the case and support cross-slats 4. (Best illustrated in Figs. 4 and 5.) This rack supports the case when it is transported to and through the dry-room. After placing the slatted rack on the inverted bottom of the case as it rests on the stripper I then place over the rack follow-blocks 5 at each end. These follow-blocks are held to the slatted rack by loop 6, which slips over the end of the follow-block and in which is mounted cams 7, Fig. 7, pivoted at 8, so arranged that the upper surface of the cam will swing against stop 8a. The lower end ofthe cam engages spring 9, secured to the bolster-plate, so that by turning handle 10 of cam 7 downward it bears on the spring, which also acts on the follow-block through the operation of connecting-rod 11 11, having hooked end 12, the lower end of which hook clamps over stripper 2, so that the upper and lower surfaces of the case are clamped between two surfaces during the process of reversing the case or holding the same from buckling or collapsing. The purpose of this arrangement is to prepare the case for reversing and delivering the same into the dry-kiln. The stripper 2, carrying 'the inverted case, is drawn on the rollers from the press onto frame 13, fixed to bracket 14, by sliding the same in groove 14L (illustrated in Fig. 11) to prevent the stripper burial-case and is held in the inverted position by pin 14, Fig. 8, in the frame, which secures the same alinernent for the movement of the strippers as the antifriction-rolls in the press, so that the stripper can be drawn out in the same horizontal line. The frame portion 13 is held in this position by notch 14, Fig. S, as hereinafter more particularly pointed out. Brackets 14 are pivoted at l5 on standards 1G, mounted rigidly on rod 17. Rod 17 is supported in supports and carries counterbalance-weight 18,which swings below the floor in order to assist in counterbalancing the weight of the stripper and burial-case when the same are swung into the position shown in Fig. 4, the counterbalancing-weight being shown only in Fig. 4. This movement is accomplished by spring-catch 19, having notches 20, the catch being moved out of engagement with catch 19, Fig. 6, in which position the parts are held vertically, the notch 20inthe spring-catch being provided to engage a stop on the stripper preparatory to swinging the case and stripper when the stripper and case are freed from the press into their reverse position. Vhen the catch in the spring is moved out of contact with the stop, the stripper and case are then swung on the bearing into the reverse position. (Best illustrated in Fig. 4.) The stripper is moved in suitable ways in the frame, preferably on antifrictionrolls 2b, as best illustrated in Fig. 8, and the ways in the frame in which the stripper moves horizontally are best illustrated in Fig. 11 at 14a. By drawing the stripper and the inverted case mounted thereon horizontally out of the frame, the stripper moving in suitable ways to permit its motion when it reaches the proper distance, its further movement is arrested by a notch in the spring-catch engaging the stop, and the same is held stationary until the operator can steady the swinging motion, when the catch is elevated out of contact with the stop and IOC IIO

the case and stripper are swung into the reverse position, (shown in Fig. 4,) where the case is deposited on supports from the door, where it is ready to be transported to the drykiln, and the swinging mechanism is ready to have the stripper removed and the case transported to the dry-kiln and the stripper returned to the press for a repetition of use. The burial-case in its reversed operation is steadied by the operator holding and steadying the handle 21, Fig. 1, during the movement of reversing the burial-case, finally resting on supporting-blocks A A on the door, the counterbalancing-weights below the floor assisting the operator in reversing the `position of the case.
