This invention relates to improvements in box blank machines and particularly to improvements in machines for making wire bound box blanks by attaching wires an cleats to sheet material and in which the box materials are fed intermittently past stapling mechanism which drives staples mto the work during the intervals between feed steps. Such machines are usually provide with mechanism for controlling the relative progression between the work and the stapling mechanism in order to position the staples at predetermined, selected points in the work. A wire bound box blank machine of the class described is shown, for example, in the patent to Seraphine F. Bauwens, 1,437 ,386 granted November 28, 1922.
Among other objects, the present invention is intended to provide such a machine with an improved braking mechanism whereby maybe more accurately controlled to position fasteners at the predetermined, selected points in the work.
The invention will be best understood by reference to the accompanying drawings, in which Fig. 1 is a side elevation of a wire bound box blank machine embodying the invention;
Fig. 2 is an end view of the machine viewed from the left in Fig. 1;
Fig. 3 is a sectional view taken on AA of Fig. 2.
The illustrative erally work-forwarding chains and feed the box materials beneath staplers 2 which apply binding wire to the box materials by forming and driving staples over the binding wire into the box materials.
The staplers 2, which may be of the type shown in the reissue patent to Thompson No 15,045 of February 15, 1921, are operate through a pitman 3 from an eccentric 4 on a are adapted at, each operation to form a staple from staple wire fed thereto and drive the same over the binding wire into the box materials. 7

10 on shaft 7 and a pawl 11 carried by a lever 12 pivotally mounted on one end of shaft 7 and having a pin and slot connection at link 13 extending from an eccentric 14 on main shaft 5, the pin and slot connection above referred to providing for lost motion between the ratchet and pawl mechanism and the eccentric 14 to permit controlling the extent of the drive stroke ofthe feed pawl 11 to position fasteners at selected points in the work.
The mechanism for controlling the feed steps of the work to position the fasteners at selected points in the work is illustrated and described in the patent to Seraphine F. Bauwens above referred to and need not be described in detail herein. It consists generally of mechanism to control the return WIREBOUNDS PATENTS or inoperative stroke of the feed pawl 11 thus controlling its operative or drive stroke.
The specific mechanism shown in the drawings comprises a lever 15 rigidly connected to the pawl carrying lever 12, a rod 16 connecting lever 15 wit a stop mechanism (not shown) of the pawl and rack type (shown in said patent to Seraphine F. Ba'uwens),
said stop mechanism being controlled by" spacer blocks or other members carried by the work-forwarding chains 1 to control the feed steps of the work to position the fasteners at selected points in the work.
To accurately position the fasteners at the selected points in the work it is desirable to sto the movement of the conveyer chains imme iately u on the termination of each drive stroke 0 the feed pawl 11'and hold during the fastenerdriving operation. Various braking mechanisms have been heretofore used in machines of this class which are momentarily thrown into operation at the termination of each drive stroke of the feed pawl but it has been found in practice that after such a brake is released the conveyer chains have a tendency to shift due to the back pull of the binding wire or other causes, thus rendering the accurate positioning of fasteners in the work diflicult.
Applicants invention contemplates a braking mechanism which is automatically thrown into operation at the termination of each drive stroke of the feed pawl and which will hold the conveyer chains against movement until the feed pawl starts its next drive stroke.
loo
As shown in the drawings, the brake is placed on the shaft 7 and is operated by a cam block 32 keyed to the main shaft 5 which cam block 15 so proportioned that the brake is thrown on at the termination of the drive stroke of the feed pawl 11 and held in braking position until the fastener-driving operation of the staplers is completed. .The
braking mechanism comprises a brake wheel" 17 keyed to shaft 7 and a divided brake shell 18 having a brake lining 19, the sections of which are pivotally connected at 20. The brake shell and its lining are supported by a bracket 21 the upper end of which is bolted a cross-frame member 22 and the lower end of which is loosely mounted on the shaft 7 (see Fig. 3). One end of the divided brake shell is secured to the bracket 21 and the other end is connected by a pin 23 to the upper end of a fulcrumed lever 24 pivoted to the bracket 21 at 25 so that When the lower moved to the left, as shown in Fig. 3, the brake shell will be expanded and lock the shaft 7 which carries the sprocket wheels 6 against further rotation.
For moving the lever 24 to expand the brake shell at the termination of a drive stroke of the feed pawl and for holding brake shell in an expanded position during a stapling operation, the lower end of lever 24 is connected by a pin and slot connection to a threaded sleeve 26 which encases and holds a screw rod 27 which is pivotally connected to a lever 28 at 29. he upper end of lever 28 is pivotall secured to the bracket 21 at 30 and the ower end carries a roller 31 which is held by means of a spring 33 against the cam block 32 keyed to the main shaft 5. The spring 33 also serves to release the brake when the cam block 32 permits movement of the lever 28 to the right viewin Fig. 3.
a will be noted that the cam block 32 is so proportioned that the brake will be on during approximately one-half a revolution of the mam shaft 5 and will be off during the steps of the and while the staples are being driven. The brake may be adjusted by turning the screw rod 27.
Among other advantages, applicants brake mechanism is simple in construction, as few parts, is easily adjusted and, being controlled as it is by a cam block on the main shaft, will positively lock and hold t e conveyer chains against movement during the periods between drive stokes of the feed pawl and while the staples are being driven thus assisting materially tioning of fasteners in the work ing a better box blank.
Obviously, the present invention is not limited to the particular embodiment shown toner-setting operation is tak in the posi- I and produc-.
and described but may be variously embodied and the particular construction shown may be variously modified as will appear to those skilled in the art. Furthermore, it is not indispensable that all the features of the invention be used conjointly since they may be used to advanta e in various different combinations and su -combinations.
