NOTCHING MECHANISM FOR CAN-BODY BLANKS.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Application filed January 28, 1910. Serial No. 540,558.

To all whom it may concern:

machinery, and more particularly to a' mechanism for treating the edges of a blank preparatory to forming the same into a can body More specifically stated, the invention relates to a mechanism for removing a part or'parts of an edge or edges of a blank, preliminary to forming the same into a can body of a certain type.

One of the objects of the invention is to produce a device of the kind described, generally known as a notcher, which is particularly compact in its structural arrangement, and simple in the disposition and mode of operation of its parts.

Another object is to provide, in a device of the kind described, a die and a cooperating notcher having inter-engaging portions, whereby the operating parts will reciprocally guide one another.

Still another object is to mount the movable member of a die-and-notcher mechanism upon a shaft, making possible an efficient and economical drive with a minimum of operating parts, and subserving compactness.

A further and more specific object is to provide the parts of a die-and-notcher with portions embracing the operating shaft, one of the operating parts being rotatable with the shaft and with respect to the other parts.

A further object is to provide the die member of such a mechanism with spaced portions engaging a driving shaft, and the notcher member with a portion embracing the shaft between said spaced portions of the die member, one of said members, preferably the notcher member, being faston the shaft.

I also aim to provide a shaft-driven and supported mechanism of the kind referred to, which is driven by practically direct and very slmple connections with the main shaft ofa can machine.

Furthermore, (and the attainment of this object is rendered possible by the disposition of parts indicated above) I aim to provide a notcher in which the operating parts are readily and simultaneously adjustable.

Other objects and aims of the invention, more or less broad than those above-stated, together with the advantages inherent, will be in part obvious and in part specifically adverted to in the course of the following description of the elements, combinations and arrangement of parts constituting the invention, and the scope of the application thereof will be defined in the appended claims.

In the accompanying drawings, which are to be taken as a part of this invention, and in which I have shown a merely preferred form of embodiment of the invention as applied to a can making machine: Figure 1 is a vertical sectional view, partly elevation, of a can machine in which this invention is applied; Fig. 2 is a sectional plan view of the subject matter of Fig. 1; Fig. 3 is a front elevation, partly in section, of a notcher device embodying the invention, showing the immediate driving connections; Fig. 4 is a detail view of the notcher proper; Fig. 5 is a sectional view, partly in elevation, on the line 55 of Fig. 3; Fig. 6 is a section on the line 66 of Fig. 3; and Fig. 7 is a schematic plan view, partly in section, illustrating the relation of devices embodying this invention to the bed of a can body machine, along which blanks are fed into operative juxtaposition with said device.

Referring to the. numerals on the drawings, 1 indicates the frame of a machine embodying various mechanisms necessary for different treatments of a blank, and for the orderly progression of the latter to each of said mechanisms. In a preferred machine I provide a main drive shaft 2, which may me actuated by means of a pulley 3 exteriorly of the machine.

4 indicates a bed arranged centrally of the machine, and 5 a reciprocating blank feed, which is adapted to move a blank intermittently along said bed, the reciprocating feed being preferably actuated by suitable connections with the drive shaft 2. In the movement of the blank along the bed it is a closure 17 for presented in turn to notching mechanisms 6 disposed at opposite sides of the bed 4, and which will be hereinafter more particularly described; thence to edging or hook forming devices 7, arranged on opposite sides of the bed; and-thence to a horn 8 about which it is bent by suitable mechanism into a can body. The edging means, the horn, and other parts of the machine are driven by suitable connections with the drive shaft, but detailed description thereof, and of their relation to the machine, is deemed unnecessary for the purposes of this specification, and because the same may be found in a copending application Serial No. 540,569 filed ofeven date.

Referring now more particularly to the notching mechanism, it should be understood that the purpose of this device is to remove portions of a blank edge, in the form of a notch or incision, as is. necessary in the manufacture of certain types of cans. To this end a blank is fed along the bed 4 edge- W158 intermittently, so that one of its phases of movement presents it in operative relation to the notching mechanisms 6, which are positioned in alinement at opposite sides of the bed. Here the notching mechanism,

.by properly timed actuations, operates to cut a notch or notches in the presented edge portion of the blank. It is to be understood that while I have shown the notchi ng mechanism at opposite sides of a machine operating on opposite edges of the blank, they are adapted for use singly. And inasmuch as the mechanisms shown are substantially identical in construction, except for such differences as are due to their opposed relation in the machine, I shall describe but one of them.

Each of the notcher mechanisms 'comprises a box-like casing 9, which is provided at opposite ends With

bearings

11 and 12 for a shaft 14. At one end the said casing is provided with a tubular extension 15 beyond the bearing 11, and the said shaft 14 projects into said tubular extension. Within said extension the shaft is provided with a pinion 16, and beyond said pinion there is the tubular extension. Preferably cast integral with the casing as thus far described is a sleeve 18, disposed transversely of the shaft bearings, and opening into the tubular extension. Within said sleeve is adapted to reciprocate a rack rod 19, which engages the pinion 16, and in its reciprocation rocks the shaft 14.

The shaft 14 is provided with a longitudinal key-way 21 and within said key-way is adapted to engage a correspondingly formed key 22 on a notcher member 24, which comprises an annular support or eollar25 adapted to be slid onto the shaft and having an integral, preferably segmental, cutting member 26, which may be of any preferred crossin Fig. 6, and abuts at its rear end against the lower part of the casing,'to which it 1s.

secured as by means of a bolt 31.

From the description thus far given it is evident that the die portion 29 is fixed in the casing, While the notcher proper oscillates toward and from it, being retained in its working position by the

collars

27 and 28. The bolt fastening 31 for the die preferably passes through a slot 32 in the casing, and obviously upon loosening the bolt the die may be slid along the shaft, carrying the notcher with it, so that adjustments of the die and notcher longitudinally of the shaft may be made simultaneously. I have shown each shaft provided with two of, the dies and cooperating notchers, and only one set of them, indicated by the numeral 34 in Fig. 3, is adjustable in the slot 32,.the fastening of the other being through ordinary bolt holes.

The die member 29 is provided with an aperture 35 extending therethrough from the face down, and a removable die plate 36- is carried on the face, being provided with a notch shaped conformably with the crosssection of the notcher part 26. It will be seen that as the shaft 14 is rocked, the notcher 26, moving with the shaft, will approach the die 29, and cut out a correspondingly shaped piece from the edge of the blank which overlies the die. The cut out piece is forced through the notch in the removable die plate and thence falls through the aperture in the die.

It will be observed that the collar 25 is of slightly larger diameter than the guiding

collars

27, 28, and that die-plate 36 is cut out and disposed to snugly fit collar 25, so that engagement of notcher 26 with its notch in the die-plate may be at all times assured.

The rack rod 19 which drives the shaft 14, as already described, is reciprocated as by means of a link 37 connected to an eccentric strap 38 which is driven from an eccentric 39 on a shaft 41 that extends transversely of the machine and which is driven by suitable connections with the main drive shaft in an obvious manner.

In Fig. 1, I have shown the bed comprising two parts in longitudinal parallelism, but movable relatively to each other, as by means of supporting pinions 42, movable on the frame of'the machine. In this manner I am enabled to adapt the bed for the accommodation of difierentsized blanks. In View section, or as shown in the drawings: Closely embraclng the member 25 are spaced of this adaptability the notchers should be adjustable toward and from each other on opposite sides of the bed, and to this end they may be carried on the sides of the bed, as shown at 4 t in Fig. 1. This attachment is preferably through the intermediary of a bracket 4.5, upon which the casing is held in adjustab e relation by means of a bolt and slot connection indicated at to in Fig. (3. If the bed members, with the attached notching device be moved, it will, of course, be necessary to move the eccentric 3!) along the shaft.

As many changes could be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative merely and not in a limiting sense. It is also to be under stood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
