CLAYTON EETERSGN, OE" SGUTH EILW'AUKEE, XVISQONSEN.
CORE-BOX CUTTER.
Application filed May 17, less. Serial no. esarir.
To all whom it may concern:
Be it known that l, CLAYTON E. PETER: son, a citizen of the United States, and resident of South Milwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented certain. new and useful Improvements in Core-Box Cutters; and I do hereby declare that the following is a full, clear, and exact description thereof.
This invention relates to a machine for cutting core boxes. r
In core boxes, as heretofore constructed, it has been the practice to form the core box by hand, at least in the finishing operations, and frequently throughout the entire process of manufacture. This necessarily results in unnecessarily expensive core boxes, and as is well known, this form of appatus is frequently the most costly of all similar devices, such as patterns, etc.
This invention is designed to provide a machine for cutting core boxes, and therefore objects of this invention are to provide a machine for cutting core boxes which may be readily manipulated and placed upon the core box, which may be readily guided, and which may be formed as a portable unit adapted for manual feeding and manipulation.
Further objects are to provide a machine for cutting core boxes, which is adjustable to acoomn'iodate boxes of varying widths, which is adapted to out a common core box having a cylindrical core cavity, which may be quickly changed to out a substantially circular core cavity, that is to say, a cavity substantially torus shaped, and to provide a machine which is rapid and olliciont in operation and in which suitable provision is made to guard the operator against dam- 4 age from the machine.
An embodiment of the invention is shown in the accompanying drawings, in which-- Figure 1 is a plan view of the apparatus shown in position upon a core box and in the act of cutting such a box, a portion of the guard or shield being broken away.
Figure 2 is an end elevation of the structure shown in Figure 1, with parts. broken away.
Figure 3 is a sectional view taken on the line 83 of Figure 1. 7
Referring more particularly to the drawings, it will be seen that the core box cutter comprises an electric motor 1, which may be conveniently provided with manipulated handles 2 upon opposite sides thereof, and which is carried by transverse bars 3, which may, if desired, be formed integral with the motor casing. These transverse bars are provided with elongated slots l; side uides 5 in the form of channel arms, as indicated in Figure 2, are positioned beneath the outer ends of the transverse bars 3, and are adjustably clamped in position by means of thumb bolts 6 to acconnnodate any size of core block. Their forward ends are preferably provided with inwardly directed lips 7, which, as shown in Figures 1 and 2, may conveniently be separate pieces of sheet metal riveted to the upper face of the side bars 5.
In order to adapt the apparatus for the cutting of torus shaped or circular core channels, an auxiliary slide 8 is provided,
which, indicated in Figure 1, is equipped with a longitudinal slot 9, adapted'to re ceive the anpropriate thumb bolt 6 and a guiding screw 10. This slide is preferably provided with lateral flanges 11, and is provided with an offset arm 12, having an aperure 13 substantially aligning with the forward elge of the cutter, which will hereinafter be described. By this construction it is possible to put a pivot pin in the core lock and slide the arm 12 thereover with such pin passing through the aperture 13. Thereafter the entire apparatus may swing in a circle about this center, and will therefore cut a circular or torus shaped core channel.
The motor shaft 1e (see Figure 3) is provided with a relatively large gear 15, which meshes with. a pinion 16, carried upon a counter shaft or auxiliary shaft 17. This shaft 17 is so mounted that its axis is substantially in the plane of the top of the core block 18. Its forward end carries a cutter receiving member 19, which is provided with a squared aperture through which the squared shank of the cutter 20 is passed-the cutter being conveniently held in adjusted position by means of the set screw 21. Any suitable means may be employed for securing member 19 in position upon the shaft; for instance, it may be pinned thereto, as indicated in Figure 3.
A convenient way of housing and supporting the shafts 17 and 14: is afforded by providing a casing 22, which cooperates with has an extension 22, which provides a pro- Jtecting housing for the cutter while 1t is executing the upper half of its revolution.
It is intended that the cuttershall be ad justed to thedesired position, and that the entire device shall be-lifted by means of the l andles 2 and placed with the lips 7 of the side guides 5 in contact with the upper face ofthe-core block adjacent its rear edge. The device is then slowly slid'forwardly onto the core blockulie rapidly rotating cutter forming a core channel across the block. Obviously the cutter may be so formed; that the entire channel may'beformed at one operation, or, if desired, the cutter may be formed and adjusted to make successively increasing cuts as the device is passed across the core block; r
1t: will'beseen, therefore, that a machinehas been provided which will rapidly form core boxes in" an extremely simple and cheap manner. V
It'will further be seen that the costly and slowhand processes are wholly avoided by this apparatus, and that a core but may be formed a power-driven machine in an effective and simple manner.
I claim: r 1; A machine for cutting core boxes comprising a frame having laterally extending arms, guides adj ustably carried by said arms adjacent their outer ends and adapted to engage opposite sides of the work,
said frame being adapted to he slid at prising a frame having laterally extending arms, guides adjustably and detachably carried by said arms adjacent their outer ends and adapted to engage opposite sides of the work, said frame being adapted to be slid at right angles to said arms longitudinally along said work, a shaft exteml ng at right angles to said arms, a cutter carried by said shaft, an electric motor mounted above said shaft, gearing connecting said shaft and said motor whereby said cutter pro jects below the lowest portion of said frame and said motor is located wholly above the axis of said cutter, and an adjustable arm carried by one of said first mentioned arms and having an aperture in lateral alignment with said cutter.
In testimony that I claim the foregoing I have hereunto set my hand at South Milwaukee, in the county of Milwaukee and State of lVisconsin.
