concern:

Be it known that I, HARinsoN B. \VALTER, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Tools for Sealing and Looking End Flaps of Boxes Together, of which the following is a specification.

My invention relates to an improvement in tool for sealing and locking end flaps of boxes together.

Thc'object is to provide means for screwing a cap upon a plug for connecting the flaps together, and after the cap has been screwed upon the plug, it is locked against movement.

To all whom it may The invention consists in certain novel and combinations features of construction of parts which will be hereinafter and pointed out in the claim.

In the accompanying drawings :--Figure 1 is a detail sectional view of a box constructed with flaps having a screw plug cap; Fig. 2 is a view in elevation of my improve tool; Fig. 3 is a top plan view; and Fig. 4 is a sectional view. v

A represents a rectangular box, the head of which is provided with four flaps, one extending inwardly toward the center from described by a hollow screw plug 2 passing therethrough, the cap 3 being received upon the lug for connecting the flaps together.

The tool B consists of two handles 4: and 5, which are pivotally connected together, as at 6. Each handle. t and 5, is provided with a jaw, 7 and 8, which taper ,toward the outer ends of the jaws. The hilts or heels of the jaws are enlarged, and the jaws taper along the sides from the hilts toward the outer ends. The outer and inner surfaces of the jaws are rounded, the inner surface being rounded whereby the screw cap can be easily and firmly gripped between the two jaws the cap. upon the plug. The tapered portion of the jaws permits of the handles being held at an angle from the end of the box, so that there will be no danger of the hand coming in contact with the box. This shape of the jaws is necessary, especially with this class of box to whichv these the plug. The pins having screw-threaded and each handle terminating at flaps are connected, as the ends are recessed, and by having the handles project or extend practically in a diagonal direction from the end of the box, the handles can be grasped and the screw cap turned without the hand coming in contact with the end of the box. Along one edge of each jaw, pins 9 and 10 are received. The pins have screw-threaded engagement with the jaws and extend in ward, and project'beyond the inner-surface of the jaws. These pins are adapted to be brought into engagement with the screw cap I afterit has been screwed upon the screw plug, and by pressure upon the handles, the pins will beforced through the screwv plug and cap, locking the two together. When the cap is being screwed by the tool upon the plug, the pins will not engage the plug, but sufiicient gripping surface of the jaws is presented for the proper hold being had upon the screw cap without bringing the pins into engagement with the screw cap. When the clenching or locking of the cap and plug is to be performed, the tool should generally be reversed, as the cap, which is generally used, will be small, and it will, therefore, be necessary to reverse the tool so that the pins can'be brought 'into engagement with the screw cap, whereby the I pins can be forced through the cap and plug for locking the two together, thereby preventing the cap from being removed from engagement with the jaws, the length of the protruding ends of the pins can be regulated to suit the requirements.

Having fully described my invention, what I desire to secure by Letters Patent, 1SZ- As an article of manufacture, a tool comprising handles pivotally connected together, one end in a jaw, said jaws presenting oppositely curved interior gripping surfaces throughout their length, and approximately circular in form, whereby to conform to the surface of a cylindrical object and grip the latter uniformly between them, the opposite edges of said jaws inclining throughout their length in op posite directions and at an acute angle to a plane drawn through the longitudinal center of the tool, said jaws having threaded orifices adjacent .to one edge and remote freln In testimony whereof 'I aflix my signature, the opposite edge, and threaded pins adjustin the presence of two witnesses. able in said threaded orifices, whereby the tdol may be deed to grip a cylindrical object, v -H.ARRISON WALTER s when with one edge down, and when with Witnesses:

the other edge down to puncture the object OLARIBEL BULLOCK,

gripped between the jaws. I FRANK O. BISHOP.
