MACHINE FOR MAKING EGG-CARRIERS.

SPECIFICATION forming part of Letters Patent No. 249,754, dated November 22, 1881.

Application filed March 25, 1881. (No model.)

To all whom it may concern:

Be it known that I, DAVID GooDwILLrE, of the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Machines for Making Egg-Carriers, of which the following is a specification, reference being had to the accom pan ying drawings, illustrating the invention, in which- Figure l is afront elevation of my improved machine. Fig. 2 is a side elevation thereof. Fig. 3 is a top or plan view of the same. Fig. 4 is a front or face elevation of the oscillating perforating-frame removed with its shaft from the frame of the machine. Fig. 5 is a front or face View of the guide which brings the perforating-frame to and from the block from which the strips are to be cut removed from the said guide and from the sash which drivesit. Fig. 6 is a side elevation of the perforating-frame removed from the frame of the machine. Fig. 7 is a view of the reciprocating head and cutting-off knife. Figs. 8, 9, and 10, Sheet 2, are enlarged views of Figs. 1, 2, and 3, Sheet 1.

The present invention relates to a machine which is designed to perforate and cut strips of wood from a block, but more especially perforate and cut strips of wood for making egg-carriers.

The nature of the invention consists in the combination ofa vertically-reciprocatingframe carrying a knife for cutting the strips from the block, and a swinging frame operated by the knife-frame so as to perforate or mortise the strips before they are cut from the block, with feed-rollers and plunger to hold the block firm to the knife as it is fed by the rollers.

Referring to the drawings, A 0 represent a substantial frame of iron of suitable form to support the mechanism hereinafter set forth in detail. Standards B B are bolted fast to the frame A and extend up such distances as by means of suitable bearings in their top ends to support a shaft, F, to which the perforating frame G is hung so as to oscillate thereon, as shown at Figs. 1, 2, and 3. The sides of this frame are provided with curved slots L, the sides of which are parallel with the face of the frame, so that the arms I) b of a guide, H, may have a free movement in them up and down. The guide H is attached to the upper rail ofthe sash-frame J, and consequently, being carried up and down with it, brings the lower portion of the frame G to and from the block. M. The guide His bolted fast to the knife-sash J at d d. Said sash is made by means of the ordinary Vshaped guides, at a, Fig. 3, to have a vertical movement between the standards B B, the power being applied to ajointed connection, H, by means of a pitman, K, in the ordinary manner, from below the machine. The knife I is bolted to the face of the sash J, and is inclined so as to make a drawing cut, so as not to check the grain of the wood or follow the grain thereof.

The perforating or mortising tool (1, Figs. 2 and 6, is to be bolted to the frame G so as to lie in a horizontal position, and on its inner face are to be secured the chisels or perforators to out any form of configuration in the wood or block M. The perforating is done just so soon as the knife passes below the block and before it returns, and to insure the proper action of the perforators the plate or part b may be secured higher upon the frame and be of any desired thickness. Care should be taken to have said tools cut at no greater depth in the block than the strips are to be thick. Therefore if the inner face of the tool (I be brought to the face of the block M, and the strips to be out are to be one-eighth of one inch thick, the chisels should project from the said inner face one-eighth of an inch. The block M is fed to the knife I by means of rollers N in the ordinary manner, so as to turn, when the knife is up, to move the block forward the thickness of a strip and then stop till the knife cuts a strip and returns up again. This is done by attaching a ratchet to the end D of shaft U, Fig. 10, and operating it by a pawl, or it may be done by any screw-feed (wellknown) which will give an intermittent feedas, for instance, the feed used in automatic stave-machines and other wood-working machinery. I employ a plunger, are, which is guided by bearings c c and held to its work against the block M by means of a chain or rope, h, attached at one end to the lower ring of the plunger shank or stem f, put over a pulley, g, and at its other end attached to a weight, 6. This is that any pressure on the block inward by the cutting-tools may not so displace itthat a strip ofthe required thickness will not be out, as would be the case if the feed-rollers were wholly relied on. The pressure of the plunger is not sufficient to move the block M under the rollers, but simply enough to hold what feed the rollers give and prevent the possibility of the knife drix'ing the block back. APIGSSUIG'fFZI-IJIO, 1 l, is pivoted to standardsR R, and by the pressure it exerts on the boxes '1, Fig. 2, which carry the rollershaft U between standards R O, the rollersN are kept'to their work.

Then the machine is constructed as al'oresaid, the block of wood is placed on the bed part A of the frame, as shown, and the plunger 11 w brought against it, as at Fig. l. The knife-sash J is then to be put in motion, as are also the ordinary feeding devices to rollers N. This will bring the perforating-tool d to its work on the block M at the proper time, and the knife I will cut the strips so fast as perforated. It will be understood that the workmanship of the machine must be good, that ac curacy and precision may be attained as the result of its operation. Legs D may be employed to support it, or a foundation substituted therefor.

I claim and desire to secure by Letters Patent- The plate H, attached to and operated by the knife-sash J, and provided with guide-arms b b, which operate in the slots L L of the frame G to bring the plate d to the block M after the knife I has severed a strip therefrom and carry the plate d from the block during the action of the knife I thereon, as and for the purpose specified.
