r a a r a. 1 I 7 EDWARD J. BROOKS, OF EAST ORANGE, NEW JERSEY.

DEVICE FOR SEALINGBOXES.

To all whom it may concern:

Be it known that I, EDWARD J. BRooKs, a citizen of the United States of America, and

a resident of East Orange, in the State of 1 New Jersey, have invented a new and useful Improvement in Devices for Sealing Boxes, of which the following is a specification.

This invention relates primarily to devices I forsecuring boxes with the aid of strap iron and seals but it is applicable to box-strap tools, or tools for tig tening box straps, for

general use.

The present invention consists H1 certaintnovel combinations of parts, and in a boxstrap .tool embodying such combinations or of them, as hereinafter more particu- 8r described and claimed. he leading objects of the invention are to render the tool as simple and powerful as possible, with reference to insuring the requisitestrength and durabilit in a tool required and adapted to embe the box strap in the corners at least of the wooden box, by tensile strain, so as to prevent the displacement of the strap on the box, and thus to render a single sealed nail all that is required strap after pre iminarilyfastening one of its ends by one other nail, permanently driven therethrough into. the boxcover, and stretching the band by means of the improved tool. Other objects will be set forth in the general description which follows: 7

Two sheets of drawings accompany this specification as parts thereof.

may be of the construction set forth and' clalmed in my specification forming part of United States Letters-Patent No. 847,276, .dated March 12, 1907, but for the purposes of the present invention is preferably driven into the top of the box cover, instead of into the bottom of a recess in the box cover as shown in the drawings accompanying that specification.

The improved sealing device or box-strap tool, shown at f, is composed of a frame, 1, a pawl-carrying hand-lever, 2, a toothed wheel, 3, interacting with said hand-lever, a strap-winding s indle or shaft, 4, rotatable with said whee, and a dog, 5, interacting with said wheel in the stra -tightening operation, as illustrated by *igs. 3 to 5, inclusive, accompanying this specification, which see.

The frame 1 is constructed with vertical and horizontal portions at right angles to each other, forming a rentrant angle at its bottom,and is-thus adapted to be applied to and to. temporarily em race, as in igs. 3,

-etc., one of the upper corners of a box, a, to

which a box-strap, b, has been preliminarily attached as in Fig. 1; and said vertical portion is preferably and conveniently pro-v vided with a spur, 6, shown in Figs. 5 and 7, which is driven into the wood to assist in temporarily holding the-tool in place on the box. The horizontal portion of the frame l-is constructed with cross bars, 7 and 8, to rest 11 )011 the box cover, and upon the ends, 1 and 2, of the box strap, and with a pair of bearings, 9 and 10, at its top, in which the shaft 4 is mounted so as to rotate freely. The hand-lever 2 is fulcrumed on the shaft 4, and is constructed with a pair of flat fulcrumembracing heel pieces, 11- and 12, in the shape of cap plates, arranged at the sides of the wheel 3, and-rigidly connected with each other and with the body, 13,- of the handlever by through screws. Saidbody 13 of the hand-lever is recessed, as shown in Figs.

(Sand 7, and within, itsrecesses a pairof pawls, 14 and 15, and a reversing :cam, 16, are pivoted, and a pair of springs, 14 and Figs. and .6,

- During this operation,-the ower disengage the lower pawl 14 and to 15, interacting with the respective pawls, are'inclosed; one or the other of said pawls interacting with the wheel 3, as in Fig. 6 or Fig. 7. Said reversing cam 16 is constructed with a thumb-piece, 17, which protrudes through a slot, 18, concentric with the shaft 4 in the front heel piece 11. The wheel 3 1s fast on the shaft 4 at mid-length; and the shaft 4 is provided with longitudinal slots, 19 and 20, on both sides of the wheel, and is mounted as aforesaid in said bearings 9 and at the to of the horizontal portion of the frame 1. he dog 5 is attached to said vertical portion of the frame 1 by a horizontal pivot, 21, and is movable within an opentopped notch, 22, in the frame, into and out of engagement with the wheel.

WVith the tool f in position on the box a, as

above described and as illustrated by Fig. 3,

the box-strap ends 1 and 2 are loosely threaded through a seal, 6, and the second box-strap end 2 is drawn beneath the outer cross bar 8 of the frame 1, and temporarily. attached to the shaft 4 by threading it through one of said slots, 19 or 20, and bending the extremity of the strap. The shaft 4 is then turned in the direction indicated by the arrow 0 in Figs. 5 and 6 by oscillating the hand-lever 2 and thereby turning the wheel 3 and therewith the shaft 4 asin said which operation is continued until the box strap 1) is tightened to a suffi cient extent to embed it in the corners ,at least of the box a, as re resented at 23. awl 14 of the hand-lever 2 interacts with t e toothed wheel 3, and retrogression is prevented by the interaction with the wheel 3 of the dog 5 in customary manner. At the conclusion of the tightening operation, the seal e is adjusted, if. necessary, as to position, and the seal nail d is driven therethrough and through both shackle ends 1 and 2 into the box cover, as represented inFig. 5 The tool is then adjusted for unwindingthe ulling end 2 of the strap, as represented by Fig. '7, which includes reversing the cam 16 so as to engage i .theupper pawl with the wheel 3. One or two oscillations of the hand-lever 2, turning the wheel 3 and therewith the shaft 4 in the.

direction represented by the arrow 5 in Fig. 7, will then suffice to unwind and dis'en age the strap end 2 from the shaft. The too f is then removed from the box, and the loose portion of the strap end 2 is ormay be removed by cutting it off as close to the seal 3 as may be desired.

The slots 19 and 20 on the respectivesides of the wheel 3, as shown in Fig. 4, adapt the tool to be used at both ends of a box with its hand-lever projecting in one and the same direction, convenient to the right hand (or left hand) of the operative.

The frame 1 of the improved tool and others of its parts may obviously be changed considerably in construction without affecting the operation of the tool; and other like modifications will suggest themselves to those skilled in the art.

Having thus described said improvement, I claim as my invention and desire to patent under this specification:

1. The combination, in a box-strap tool, of a frame having vertical and horizontal ortions forming a rentrant angle at its ottom adapted to tem orarily embrace one of the top corners of a ox, a pawl-carrying hand lever, a toothed Wheel mteractmg therewith, a longitudina y Slotted Shaft mounted in said frame for g h fu um of said hand-lever and rota b h a wheel, and a'dogpivoted to sal frame an interacting with said wheel.

2. The combination, in a box-stra tool, of a frame having vertical and horizontal portions, adapted to temporarily, embrace one of the top corners of a box and constructed with cross bars at the bottom of said horizontal portion to rest upon the box cover and box strap, a pawl-carrying handlever, a toothed wheel a longitudinally slotted shaft mounted in said horizontal portion of the frame, forming the fulcrum of said hand lever and rotatable with said wheel, and a dog pivoted to'said vertical portion an wheel. 7

3. The combination, in a box-stra tool, of a frame adapted to be temporarily eld in working position on a box, a longitudinally slotted and frame, a toothed wheel fast on said shaft, a hand-lever carrying a pair of s ring-pressed pawls and a reversing device w ich lifts one or the other. of said pawls to determine the interacting therewith,

interacting with said rotatable shaft mounted in said direction of, rotation, and a dog pivoted to I said frame and interactin' with said wheel when the wheel and sha t are rotated to tighten the box strap.

4. The combination, of a framevhaving, vertical and horizontal portions and ada ted to embrace one of the top corners ofa ox, a'pawl-carrying handlever, a toothed wheel interacting therewith, a rotatable horizontal shaft mounted in said horizontal portion of the frame, having said wheel fast thereon at mid length, con structed with longitudinal slots on both sides of said wheel and forming the fulcrum of said hand-lever, and a dog pivoted to said vertical portion of the frame and interacting with said wheel, substantially as hereinbefore specified.
