BOX-BAND STRETCHER.

Specification of Letters Patent.

Patented Apr. 9, 1918.

To all whom it may concern:

Be it known that I, RALPH H. Non'rox, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Box-Band Stretchers, of which the following is a specification.

In some instances it has been the practice in securing a band about a box or other article to secure the ends thereof together by means of a buckle of some kind and in other instances the ends of the band are secured together without such device. My invention relates to a tool for drawing the ends of a band for boxes and the like toward or past each other and thereby stretching the band and maintaining the ends in proper relation while they are being suitably secured. In the preferred form of the invention the tool is adapted for fastening such a band by means of a buckle. In another form of the invention the tool is adapted to stretching bands in which no buckle is employed for securing the ends thereof together. In each instance, however, the tool includes means for gripping both ends of the band and forcing them toward each other, in the one case, the pressure being applied to the buckle on onehand and directly to the band on the" other, and in the other case applied directly to both ends of the band. The construction of the device is simple, comprises few parts, is not apt to be broken or rendered inoperative and is easily manipulated for the purpose in view.

In the accompanying drawings, I have shown and described two preferred forms of the invention, one of which is particularly adapted for use in tightening box bands where a buckle is interposed between the two ends of the band for the purpose of securin them together, and the other of which is particularly adapted for use in connection with bands having no buckles for uniting their ends. It is to be understood, however, that the specific disclosures are for the purpose of exemplification only and that the scope of the invention is to be ascertained from the following claims in which I have endeavored to distinguish it from the prior art so far as known to me without, however, relinquishing or abandoning any part or feature thereof.

Referring now to the accompanying drawings, Figure l is a slde elevation of a portion of a box with a strap or band applied thereto and that form of the device which is particularly adapted for use in connection with buckles in one of the positions which it assumes when being used; Fig. 2 is a horizontal section upon the planes of the line 2-2 of Fig. 1, of the same device; Fig. 3 is a vertical section of the tool partly in elevation upon the line 33 of Fig. 2; Fig. 4 is a transverse section upon line 44 of Fig. 1, and Fig. 5 is an elevation of a box with a band applied thereto without any buckle and that form of my device adapted to apply such bands, a part of the latter being shown in vertical section to better disclose the construction.

Referring first to Figs. 1 to 4 inclusive, the buckle A which the tool is particularly adapted and intended to apply is best seen in Fig. 2 and comprises substantially a thin metal plate having a trapezoidal opening therein to receive the ends of the band. One end B of the band is thrust through the opening in the buckle from above and folded around the same and under the body of the band and thereby securely attached to the buckle. The other end of the band is passed through the opening from below and bent backward around the inclined interior edge D and the inclined exterior edge E and beneath the buckle. In the drawing, however, the buckle is shown with the end B fully attached thereto and the end C inserted through the opening but not bent back around the edge D. This form of buckle forms the subject-matter of an application for United States patent filed by me of even date herewith.

The tool comprises a main lever body 6 which is provided with means for grasping one end of the box band and a link 7 for engaging and drawing the buckle toward the other end of the strap. The link 7 is scribed after it has been appliedtoan end "9, to which reference has been made above.

The lower end of the lever terminates-ina foot or anvil 15 substantially at right angles tothe body thereof and a reciprocable pin or bolt 16 extends through an'opening in lever .21 is pivoted at 22. A shoulder 23 is the boss or offset 14 of the lever and through a bore 18 (see dotted lines, Fig. 1) formed in an enlargement 19 of the casting or lever. The enlargement 19 is also slotted or formed with a pair of lugs 20 between which a hand formed on the hand lever 21 just above and adapted to bear upon the upper endof the pin or bolt 18, the construction being such that when-the handle 21 approaches the rigid handle 24 upon the lever the shoulder engages the bolt 18 and forces the same downwardly. A coiled spring 25 is interposed between the lower ofi'set l t-and a transverse pin 26 on the bolt 18 and normally maintains said bolt in its upper position and out of engagement with the jaw 15. It will now be obvious that when the hand lever 21 is grasped in taking hold of the tool the shoulder 23 engages the upper end of the pin 18 and forces the same down.- wardly so that the lower. conical end 27 of said bolt engages a slightly hollowed seat 28 upon the anvil 15, or if a band or the like is upon the anvil at the time itbends'or raises a cup in the Land by which latter and the pressure between the parts thelever is prevented ,from moving relatively to, the band.

In operation the buckle is first secured to one end of the band in the manner abovedescribed and the link engaged with one edge of said buckle, the lever being engaged in the manner. above described with the other end of the band. Upon grasping the rigid andpivoted handles-21, 24, as shown in Fig. 1, the tool is caused to grasp the band at :1 Suitable point and the link being already engaged with the proper edge of the buckle v and with the end of the bandto which the" buckle is attached extending through the buckle or passage through the head of the .link, movement of the lever to the left, as

shown in said figure, I stretches the band tightly about the box or other article to which it is applied. The forward end of the buckle is'prevented from slipping out.

Y which has been 5 That form of the tool of its grooved seat in the link by the lu 7 on said link extending overthe forwar part of the buckle.

The stretching action of the tool forces the free end of the band v passed through the opening 1n the buckle farther'therethrough and when the band is sufiiciently tight, said end is bent about the inclined edge of the opening upon the lever, which parts operate in much the same way as the similar parts of the form of tool shown in Figs.'1 to 4 inclusive. 1

It is necessary, however, to modify the form of the holding means upon the link in order to adapt it to grip the bale band instead of receiving the buckle. link 7 is formed with a lateral support or anvil 31 adapted to be inserted between the end of the band to be grasped thereby and the box and a dog 32 is pivotedto the link above said support at 33 and formed with a sharpened end 34 adapted to engage the band. It will be noted that any relative movement under tension between the gripped end 35 of the hand and the link only tends to cause the dog to grip the band the tighter by reason of the position of the pivot with reference to the support and. the length of the dog. A handle 36 facilitates swinging the dog against spring 42 when desired. As it is desirable in fastening the ends of the band together that the operator have both hands free, I have provided means for maintaining the link and lever in the position to which they are carried when the desired tension has been put upon the band. For this purpose a ratchet bar 37 is pivoted upon the same pivot 33 which carries'the dog and extends in the general direction of the link but beyond the lever where it is formed with a series of ratchet. teeth 38 and a handle 39. The pivoted handle 21* by which the bolt 18 is operated is in this case prolonged beyond its pivot into an arm 40which is perforated at its lower end at 41,to receive the end of the ratchet bar 37. In operation the dog and support upon the link are first caused to engage one end of the band and the anvil 15 uponthe lever engaged-beneath the otherend of the band. By gripping the For this purpose the pivoted handle 21 the bolt 18 is caused to engage the band upon the anvil 15 and grip the same, and the lever is then pressed to the right, as shown in Fig. 5.

r The pressure onthe handle fll. and the motion thereof with that of the main lever 6 to the right feeds the latch bar 37 through the opening 41 in the arm and therefore when the band is sufiiciently stretched and the pressure on the tool is released it maintains its position freeing the hands of the operator to secure the ends of the box band together. Obviously the ratchet bar shown in Fig. 5 could readily be applied to that form of the device shown in Fig. 1.
