IVILLIAM G. KLEINFELDER, OF CHICAGO, ILLINOIS.
TOOL-STOCK.
SPECIFICATION forming part of Letters Patent No. 632,312, dated September 5, 1899.
pplication led November 8, 1898 Serial No. 695.825. (No model.) i
.To @ZZ whom t may concern:
Be it known that I, IVILLIAM G. KLEIN- FELDER, 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 Tool-Stocks, of which the following is a full, clear, and exact specification.
My invention relates more particularly to tool-stocks for planing-machines in which the tools are held either vertically or at an oblique angle to the work by means of set-screws or other devices, it being the custom to employ a gang or number of such tools in each stock.
One of the objects of my invention is to provide means whereby the cross-head or stock which holds the tools may be considerably elongated for accommodating a -large number of tools without resulting in that action of the tools during the cutting operation` known as chattering7 V Another object of my invention is to provide improved means whereby the same set of set-screws may be employed for binding in place a plurality oftools, and a further object of my invention is to provide means whereby the tool-stock may be set at various angles with relation to its carrying-head, so that the tools will not track one behind the other, but may be caused to cut into the work different distances, as desired.
IfVith these ends in View my invention consists in certain features of novelty in the construction, combination, and arrangement of parts by which the said objects and certain other objects hereinafter appearing are a*- tained, all as fully described with reference to the accompanying drawings and more particularly pointed out in the claims.
In the said drawings, Figure l is a side elevation of a planer-head of the usual construction provided with my improved tool-stock.
Fig. 2 is a front View thereof looking at right angles to the view in Fig. l. Fig. 3 is a plan section taken on the line 3 3, Fig. l. Fig. 4 is a plan section taken on the line 4 4, Fig. l. Fig. 5 is an oblique section taken lengthwise of the tools and longitudinally of the crosshead of the tool-stock. Fig. 6 is a View similar to Fig. Al, illustrating my improvements as applied to a surface-planer; and Fig. 7 is a plan view thereof.
l represents the planer-head, provided on one sidel with a pair of flanges 2, between which is pivoted on the pivot or bar 3 the usual swinging apron-block 4, whose outer face is provided with the ordinary gripping plates or jaws 5, against which rests the stem 6 of the tool-stock in the ordinary manner. This stem may be clamped against the roughened jaw-plates 5 by any suitable means, but preferably by the usual clamping-plates 7 and bolts 8, two of which latter are arranged 011 each side of the stem 6 and pass into the planer-block 4.
The cross-head 9 of the tool-stock in the example shown is provided with slots for the accommodation of a gang consisting of four tools 10, and these in the particular illustration are set at an oblique angle, as shown in Fig. 2. These tools l0 are held in place by one or more set-screws ll, threaded in each end of the cross-head 9. As more clearly shown in Fig. 5, the set-screws impinge directly against the end tools, whose cavities or slots in the cross-head are slightly larger than the width of the tool, so that the pressure of the screws forces the end tools against the outer ends of one or 4more (preferably two) binding-pins l 2, arranged horizontally in suitable passages between the outer and inner tools and being of sufficient length to reach and firmly impinge the inner edges, so that the pressure of one set of set-screws ll serves to bind in place a plurality of tools. I have shown four tools; but it is of course obvious that any number might be employed and the same principle of binding carried out by simply duplicating the binding-pins l2. This elongation of the head 9 in order to accommodate a large number of tools produces greater leverage on the stem G, and consequently renders the end tools unstable and multiplies the vibratory effect known aschattering, which is of course also augmented by extending the stem 6 downwardly from the head l, and in order that this chattering effect may be prevented I provide the cross-head 9 with a brace which takes its bearing against the bottom of the apron-block 4 and holds the cross-head 9 against upward vibration, such brace being of course located at the end and side of the cross-head opposite the cutting edge of the tools, so that the pressure against IOO -by set-screws 16, as usual.
such cutting edges will always tend to force the brace against the bottom of the apronblock. This brace may consist of an ordinary bolt 13, having its head abutting against the bottom of the apron-block 4t and its threaded end screwed into the cross -head 9, the cross-head being provided on one side with a boss 14, so that the bolt 13 may not interfere with the pins 12 and may also be as far from the cutting-points 10 of the tools as possible. The bolt 13 is held at its adjustment by jamnut 15. Thus it will be seen that when the planer-head 1 makes its return movement the brace 13, together with the apron-block 1.1-, will swing outwardly, and such brace will always be in position to hold the cross-head 9 and lower end of the stem 6 against vibratory movement. Should it be desired to elongate or lower the stem 6, the brace 13, being adjustable, may of course be elevated until its head strikes against the bottom of the apronblock 4C.
In Figs. 6 and 7 I have shown a tool-stock more especially adapted for holding surfaceplaning tools, which, as usual, has the crosshead 9a set off to one side of the stem 6, and the tools 10 are arranged vertically and held In this example of surface-planer the cutting edges of the tools 10b are arranged on the side of the head 9 next the set-screws 16, and consequently the brace 13 is located on the opposite side of the head 9a. NVith planers of this character it is often desirable to change the angularty of the line of the gang of cutters with reference to the line of their bodily movement across the face of the work, and in order that this may be done I locate between the back of the stem 6a and the jaws 5 a Wedge-shaped plate or shim 17, which is sufliciently narrow to pass down between the binding-bolts 8 and is of sufficient length or vertical extent to permit of the vertical adjustment of the stem 6a. To facilitate in placing the plate 17, I provide the back of the stem 6 with a pin 18, which passes through a corresponding hole in the plate 17. It will of course be understood that plates 17 of various angles may be kept on hand and the one which has the proper angle for the particular work to be done will be inserted.
Having thus described myinvention, what I claim as new therein, and desire to secure by Letters Patent, is
1. The combination of a tool-stock for planing-machines, the planer-head to which said stock is pivotally secured and a brace between said stock and head for preventing vibration of the stock, substantially as set forth.
2. The combination of a planer-head, a toolstock pivotally and adj ustably mounted thereon and a brace adjustable with relation to said head and having abutment against said tool-stock and against its pivotal support,sub stantially as set forth.
3. The combination of a planer-head, an apron-block pivoted therein, a tool-stock secured to said planer and a brace secured to to said stock and abutting against said apronblock, substantially as set forth.
4. The combination of a planerhead,an apron-block pivoted therein, a tool-stock adjustably secured to said apron-block and an adjustable brace abutting against said toolstock and apron-block for preventing vibration of the stock, substantially as set forth.
5. The combination of a planer-head, a toolstock carried thereby and a brace impinging said tool-stock on the side opposite or remote from the side on which the cutting edges of the tools are located, for holding said toolstock against vibration, substantially as set forth.
6. The combination of aplaner-head, a toolstock having ai stem and a cross-head, said stem being adj ustably secured to said planerhead and said cross-head being provided with means for holding the tools, and an adjustable brace between one end of said cross-head and the planer-head, substantially as set forth.
7. The combination of a planer-head, an apron-block pivoted therein, a tool-stock consisting of a stem and a cross-head, means for adj ustably clamping said stem to said apronblock and a bolt threaded in said cross-head and abutting against said apron-block and serving as a brace for holding said cross-head against vibration, substantially as set forth.
8. The combination of a tool-stock having a number of slots or passages for the tools, the tools located therein, pins passing between said tools and abutting thereagainst, and means for forcing the end tools toward said pins whereby the pins Will be caused to grip or bind the inner tool, substantially as set forth.
9. The combination of a tool-stock having slot-s or passages for the tools, the tools in said slots or passages, pins located between said tools and being of greater length than the distance between the adjacent walls of said slots or passages, and set-screws threaded in said stock and impinging against the outer tool, substantially as set forth.
10.. The combination of the apron-block having the gripping-jaws 5, the clamps 7 and bolts 8, the tool-stock having a stem adapted IOO to be clamped by said plates and bolts and a Wedge-shaped plate 17 located between said stem and jaws 5 and being vertically elongated, substantially as set forth.
