Box-MAKI MACHINE.-

SPECIFICATION forming part of' Letters Patent No. 478,456, dated July 5, 1892. I Application filed November 28, 1891 Serial No. 413.433. (No model.)

To all whom itmayboncern:

Be it known that I, JOSEPH CAMERON Mc- EWEN, acitizen of the United States, residing at Lochloosa, in the county of Alachua and State of Florida, have invented certain new and useful ImprovementsinBox-Making Machines; and I do declare the following to be a full, clear, and exact description of the in-.

object the providing of a machine for holding in proper position the parts" of the box during the process of assembling, and nailing. To these ends and to such others as the in "vention may pertain the same consists in the 'pecullar construction and in the novel combination, arrangement, and adaptation of parts, all as more fully hereinafter described, shown in the accompanying drawings, and then specifically-defined in the appended claims. V

In the accompanying drawings, which form a part of this specification, and in which like of heavy timbers and should be ofconven-- ient height and of a length andwidth to adapt it to use in the construction, of boxes of the size which itnn'ay be proposed to manufacture. The upper face of the table B of the machine is provided with a series of transverse recesses or spaces 0 to receive the lower crate to be constructed. Rising from the table B at its rear edge arethe uprights E E, and supported upon these uprights is a shelf F, which is provided with a raised strip F, extending around its outer edges. is designed as a receptacle for} nails, so that the nail-supply may at all timesybe within convenient reach of the operator.

with a series of notches F which serve to receive the edges of 'thelbox-heads D and hold as shown. v

G is a rock-shaft, which is journaled within suitable bearings at the rear of the frame A and provided at one of its ends with an operating lever or handle G.

are provided at their free ends with presserposition in themachine will press against the faces of the heads and hold the same securely in position for nailing, as shown clearly in Fig. 1 of the drawings.

In order to insure a firm pressure of the blocks H against the box-heads, a pin or lug I is provided upon the rock-shaft at a point near one of its ends, and when the shaft (which is longitudinally movable in its bearings, as shown) is'turned so as to cause the blocks H to contact with thebox-heads this lug engages an inclined surface H upon the frame A and the shaft is thus forced along in a direction which will tend to carryv the blocks H into close contact with the boxheads, as will be readily understood. In order that the pressure-blocks may-beautomatically thrown out of contact with the box-heads when the lever G is thrown upward, I provide a block J, which is secured to the end of the upright portion or shelf F. This strip or block is cut away at its forward end, as shown, said cut-away portion forming an inclined surface against which the lever G contacts when thrown upward. This contact of the edges of the ends or heads D of the box or.

This shelf The front edge of the shelf F is provided the same steadily in place when being nailed,

This rock-shaft is provided with a series of arms H H, which blocks H, which when the boxrheads are in leverwith the block will have the, effect of throwing the lever outward, carrying with it the shaft G and moving the presser-blocks out of contact with the box-heads.

The operation of the machine is simple and will be readily understood. The shaft G is thrown upward and the box or crate headsp are placed in position within.the recesses C, with the rear edges inserted within the notches in the shelf F. The operating-handle is then thrown forward, as shown in Fig.1, and the pre'sser-blocks are forced against the faces of the box-heads, which are thus securely held in position for receiving the slats or sides of the box. When one of the sides of the box has been nailed the lever is raised or thrown back, thus releasing the presserblocks from'engagement with the heads D.

While I have shown a machine adapted for use in the construction of orange-boxes in which three heads are used,- it is at once evident thatthe principle involved is equally well adapted for use in the manufacture of any of the various forms of boxes.

Having thusdescribed my invention, what I claim to be new, and desire to secure by Letters Patent, is

1. The combination of the main frame hav ing recesses to receive the bottom and rear edges of the box-heads, a rock-shaftjournaled to the rear of the frame, the arms H attached to the shaft and carrying presserheads, as described, and the operating handle 0r lever for actuating the shaft, substantially as and for the purpose described.

2. The herein-described machine for use i in the manufacture of boxes or crates, the

same comprising the main frame having recesses to receive the lower edges of the boxheads, the shelf to the rear of the frame and supportedupon uprights risingfrom theframe,

the rock-shaft j ournaled to the rear portion of the frame and longitudinally movable within its bearings, the arms attached to the shaft,

the presser-blockscarried by the arms-,- the lug Inpon theshaftand engaging an inclined surface upon the frame, and the lever for actuating the shaft, substantially as and for the.

purpose described.

In testimony whereof I affix my signature in.
