MACHINE FOR USE IN- MAKING BOXES.

Application fi1ed 0ctober 2s, 1920. Serial No. 420,210.

To all whom it may concern:

Be it known that 1, Bacon J. 'Davmson, a citizen of the United States, and. a res1- dent of Marseilles, in the county of La Salle and State-of Illinois, have invented an Improvement in Machines for Use in Making Boxes, of which the following is a specification. I

The invention relates to machines for use in fastening heads, ends, partitions or the like to boxes, crates and the like.

Among. other objects the invention is intended to provide a machineof the class described, having improved means for controlling or positioning the" work during a fastener driving operation.

The invention will be best understood by reference to one illustrative embodiment thereof shown in the accompanying drawings in which:

- Fig. 1 is a general perspective view of a machine embodying the invention.

Fig. 2 is a side elevation of the machine showing a. crate partly broken away in position to be operated upon.

Fig. 3 is an enlarged top plan View of the nose of the machine showingthe work controlling means.

Fig. 4 is an enlarged front elevation of the nose of the machine showing a crate in position to be operated upon.

I Figs. 5, 6 and 7 are plan views of the nose of the machine showing acrate being operated upon in different positions; in

these figures for clearness of illustration, the lower arm which carries the staple driving mechanism is shown in full lines and the upper arm which carries the work controlling means is shown in dotted lines.

Fig. 8 is an enlarged perspective of the work controlling means for positioning the work. i v

Fig. 9 is a top plan view of the same.

Fig. 10 is a front elevation of the same.

Fi 11 is a sectional view taken on the line --A of Fig. 9.

Fig. 12 is a perspective of one end of a wirebound crate s to the cleats of the crate sides.

One illustrative type of crate upon which the machine is designed to operate is partly illustrated in Fig. 12. This illustrative owing an end stapled crate is a wirebound crate comprising four side sections of slatted side material a and cleats I) connected together in foldable relationship with binding wires 0' stapled thereto, and heads or ends d stapled to the cleats b of one or'more side sections by staples e. In practice the materials for the four sides of the crate are usually assembled and secured together in a crate blank machine which connects the four sides of the crate with wires producing what is commonly referred to as a crate blank. The blank is then partially folded about the heads .or ends 03, as shown in Fig.'12 and the heads or ends are then side cleats b. i

The illustrative machine is for use in performing this head or end fastening op eration and is designed to operate within the crate, close to the sides thereof and in the corners and to drive staples throu h the head or end (Z and into or through the cleats b.

As illustrated in Fig. llthe invention is embodied in an end stapling machine of the type disclosed in the atent to Thompson, #1,295,237, issued ebruary 25, 1919, consisting generally of staple formin and driving mechanism, and clamping or c inching mechanism to cooperate therewith during a staple driving operation. It will be understood, however, that the invention is not limited to the particular end stapling machine illustrated but maybe embodied in other types of which there are several.

The illustrative machine is supported by the frame 1 which carries arms 2 an having an opening therebetween to permit the insertion of a box or crate and its end or head as shown in Fig. 2. Arm 2 which carries the staple driving mechanism is formed with a narrow nose adapted to enter a box or crate, close to the sides thereof and in the corners and arm 3 carries the clincher mechanism for clamping fastened to the staple driving operationand for clinching any staples that may be driven-through the materials. Staples 4 are formed from wire 5 by staple forming mechanism (not shown) located at the rear of the machine and are fed forward to the'nose of arm 2 with. their are driven upward through the head or.

end d into the cleats b of the crate or box.

The mechanism for forming, feeding and driving the staples and the clincher mechanism need not be shown or described in detail as said mechanisms are fully shown and described in the patent to Thompson above referred to.

In operation a head or end 03 is placed upon the upper surface of the lower arm 2 and the three sides of the box or crate are wrapped about the head or end with the cleats b above the end d. Staples are then driven at intervals through the head or end (1 and into the cleats b of side sections of the box or crate. For clearness of description the side sections of the crate illustrated inFigs. 5, 6 and 7 have been designated S,'S' and S Staples are usually driven into the cleats of all three of these sections although in some instances it has not been found necessary to drive staples into more than two of said sections.

To increase the holdingpower .of the staples it is desirable to drive them along the longitudinal center line of the cleats.

As shown in Fig. 5, therefore, thedriving point X is located at such a distance relative to the nose of the'arm Qthat when a box or. crate is placed upon said arm the side material of the crate or box will not prevent the proper positioning of the cleat over the driving point.

Heretofore, as in the machine of the Thompson patent above referred to, the work was positioned for a stapling operation by the nose of the stapling arm which contacted with or engaged the side material of the box as it was pressed against the nose by the operator and as the box was shifted foreach stapling operation the nose of the stapling arm dragged along the inner surface of the side material at all times positioning the driver relative thereto and relative, to the cleat. Such a work-controlling means is effectual for positioning a box having in effect, integral or continuous side material. It has been found in prac-- tice, however, that when a crate having,

openings in the side material is being oper-, ated upon that the nose of the stapling arm often catches in such openings or partially passes through them thus improperly positioning the work, causing inaccurate positioning of staples and otherwise delaying the stapling operation.

In the illustrative machine, work controlling means for properly positioning the materials for the fastening operation, regardless of openings in the sides of the work, is provided.

As illustrated, said means takes the to naespae of an independent attachment to the under Fi 12 has no 0 enin s into which the,

work-controlling means may enter as the work is shifted for successive operations.

Referring to Figs. 8 to 11 the illustrative work-controlling means comprises a member G, adapted to engage the cleats-of a box or crate and so position the parts rela tive to the staple driving mechanism that the cleat will be properly positioned over the staple driving mechanism and the side material of the box or crate will be held clear of any engagement with the nose of the lower arm 2.

To facilitate shifting the work for successive stapling operations said member 6 is preferably rotatable and in the present instance takes the form of a roller against which the cleat ot' the box or crate is pressed. Y

.at approximately right angles to the longitudinal center line of the stapling arm 2 so that the work will be properly positioned for a stapling operation regardless of the position of the member 6 relative to the longitudinal center line of the stapling arm.

Sides S and S however, as shown in Figs. 6 and 7 are pressedtoward the side of the stapling arm and shifted on an angle "oi-responding to the angle of the side of the arm relative to its longitudinal center line. To roperly position the parts when the sides i and S are being stapled provision is made for shifting the position of the member 6 relative to the longitudinal center line of the stapling arm so that the cleats of the sides S and S may be properly positioned for a stapling operation.

As shown in Figs. 8, 9, 10 and 11, member 6 is carried by a bar 7 reciprocable horizontally in guides 8 in the body member or frame 9 which in the presentinstance is, adjust-ably secured to the under side of the upper arm 3 by set screws 10 or in any other suitable manner.

To limit the reciprocations of bar 7. to control the position of the member 6, said bar is provided with a member 11 adapted to contact alternately with members '12 and 13 respectively carried by the body member 9. Members 12 and 13 which in the present instance take the form of screws may be adjusted to control the extent of reciprocation of the bar 7 thus controlling the position of the member 6.

S has pressed member 11 to the limit of its reciprocationagainst-member 13 which has been adjusted to properly position member 6 to control the position of the work while section S is being operated upon and, as shown in Fig. 7, the cleat of section S has pressed the member 11 to its other limit of reciprocation against member 12 which has similarly been adjusted to properly position member 6 to control the position of the work while section, S is being operated upon.. I

Thus it will be noted that work-controlling means is provided to properly position. the work and prevent the nose of the stapling arm from entering openings or spaces in the side material; that-said means is rotatable and reciprocates in response to the shifting of the Work thus automatically adjusting itself to the movement and position of the work; and that, said means gauges or positions the work from the cleats.
