$PEGIFICATION forming part of Letters Patent No. 741,141, dated October 13, 1903.
' Application filed June 16,1908. Serial No. 161,735. (No model.)
To all whom it may concern.-
Be it known that I, ADOLPH E. KASTIEN, a citizen of the United States, residing at East Peoria, in the county of Tazewell and State of Illinois, have invented a new and useful Link-Cutting Attachment for Milling-Machines, of which the following is a specification.
This invention relates to link-cutting attachments for milling-machines, and is especially designed for use upon milling-machines having a reciprocating bed upon which the work is carried under a rotating cutter-shaft supported in fixed bearings.
The object of the invention is to produce a simple and effective attachment for millingmachines of the type above mentioned by means of which the machine may be used to cut or finish curved engine-links for locomotive, stationary, or traction engines.
Another object of the invention is to produce a link-cutting attachment for milling-- machines of the type specified that may be readily attached or detached from the milling-maohine.
With the objects above stated and others in View, which will appear as the invention is more fully disclosed, the same consists in the construction and combination of parts of a link-cutting attachment for milling-machines hereinafter described and claimed, and shown in two slightly-different forms of embodiment in the accompanying drawings, in which corresponding parts are designated by the same characters of reference in the several views in which they appear.
In the drawings, Figure 1 is a view in perspective of the attachment for dressing the upper portion of a link supported upon an arm ofa milling-machine, shown diagrammatically in relation to the attachment. Fig. 2 is a perspective view similar to Fig. 1 of the attachment for dressing the lower part of a link. Fig. 3 is a View in elevation ofthe carrying-arm of the attachment shown in Fig. 1. Fig. 4 is a view in elevation of the carryingarm of the attachment shown in Fig. 2. Fig. 5 is a View in elevation of a link of the form upon which the link-cutting attachment is designed to operate.
Referring to the drawings fora specific description of the invention, M designates gen erally a milling-machine having a reciprocating bed B, a stationary arm A, on which is supported a pendent bracket P, which has in the lower end thereof bearings for one end of a cutter-shaft S, the other end of which is suitably supported in bearings formed in the main frame F of the machine. The shaft S is provided with milling-cutters C and O of ordinary type fixed thereon, and motion is imparted to the shaft by means of driving mechanism which forms no portion of this invention and which is not shown in detail.
The attachment which forms the subject of this invention comprises a supporting-arm 1, having at the lower end a split collar 2, having at the open sides thereof lugs 3, provided with alined apertures through which passes a bolt 4, by means of which the lugs are drawn together. The collar 2 is of suitable size to fit the supporting-arm A of the milling-machine and may be applied thereto by removing the pendent bracket P and slipping the collar 2 over the free end of said arm A. The arm 1 when placed in operative position upon the arm A extends vertically upward and has near the upper end thereof astud 5 which forms a pivot upon which may be mounted either of the members 6 or 7. The member 6 is the work-support upon which the work 'is carried when the milling-machine is operating upon the front part L of the link, and the member 7 forms the work-support upon which the work is carried when the machine is dressing the rear portion L" of the link. The member 6 is provided at the top with an opening 8 of suitable size for the passage of the stud 5 and is also provided near the bottom with a curved slot 9, through which the arm A of the milling-machine passes when the member 6 is in operative position upon the machine. The ends of the slot 9 serve to limit the movement of the member 6, as they contact with the arm A when the member 6 is swung as far as possible in either direction. Near the bottom of the member 6, which is curved in an are having a radius extending from the center of the pivot-opening 8, are provided two studs 10 at a proper distance to engage openings in lugs L on the link and between the studs 10 with an opening 11 for upon the supporting member 6. When part L is supported upon the member 6 and secured thereon by means of the devices above mentioned, the member 6 will be in the position shown in Fig. 1, and motion then being imparted to the machine the bed B will be caused to travel in the direction indicated by the arrow until the angular lug T, bolted upon the bed, moves forward and engages with one side of the supporting member 6 and forces the member to travel forward with the bed, bringing the front portion L of the link into engagement with the cutter O. The supporting member 7 has at the top a pivot-opening 13 for engagement with the stud 5 upon the arm 1 and at the lower end is formed into a frame 14, the upper portion of which is open for the passage of the arm A and corresponds to the slot 9 in the member 6. The lower part of the frame 14 is curved on a radius extending from the center of the pivot-opening 13, and on each side is a curve 16, which forms a surface of contact for the shaft S when the member 7 has reached the limit of its pivotal movement. The lower portion of the frame 14 is provided with a recess 17, adapted to receive the link L, and a plurality of set- screws 18, 19, 20, 21, and 22, suitably arranged at the end, side, and bottom of said recess, form means whereby the link may be securely clamped in the recess 17 in proper adjustment to the cutter C. When the rear portion L of the link is mounted in the recess 17, it will be in position to be engaged by the cutter O, and motion will be imparted to the member T by means of the angular stop-lug 7 on the bed B in the same manner that motion was imparted by said lug to supporting member 6, as above explained.
It will be seen from the foregoing description and from an inspection of the accompanying drawings that the link-cutting attachment forming the subject of this invention is of extremely simple construction and is adapted to be readily placed in position upon a milling-machine of the form for which it is designed and that it is adapted to give effective service without wear or other injury from use. p
In using the machine it is to be understood that after the arm 1 has been placed in position upon the arm A with the supporting-arm 6 mounted upon the pivot 5 it is desirable to complete the dressing of the front portion of as many links as possible before beginning the dressing of the rear portions of the links, as whenever it is desired to remove the member 6 from the pivot 5 and substitute the member 7 therefor it is necessary to remove the bracket B and the arm 1 from arm A and reassemble the parts of the attachment.
As the link-cutting attachment is of extremely simple construction and is inexpensive to manufacture, it is more desirable to provide a plurality of attachments of different sizes for the dressing of links having different radii of curvature than to make a single attachment having means for adjusting the height of the pivotal point above the cutter-shaft and means for adjusting the pivotpoint of the supporting members to correspond, as whenever adjusting devices are employed the cost of manufacture of the linkcutting attachment is greatly increased and its positiveness of operation is, in a measure, diminished. Moreover, as will be obvious, any form of adjusting devices which might be used would be subject to wear, which would destroy the accuracy of the work of the attachment, and so render it ineffective for the purpose for which it is primarily designed.
Having thus described the nature and operation of my invention, what I claim as new,
and desire to secure by Letters Patent, is-- 1. In a link-cutting attachment for millinglnachines, a supporting-arm having a clamp for engagement with an arm ofa milling-machine and a link-carrying member mounted for pivotal movement upon said supportingarm and provided with means for securing a link thereon.
2. In a link-cutting attachment for millingmachines, a supporting-arm having at one end means for securing it in fixed position upon a milling-machine and at the other end a stud adapted to form a pivot, a link-carrying member pivotally mounted on said stud and having an opening for the passage of the stationary part of the milling-machine on which the supporting-arm is mounted, and means for clamping a link upon said carrying member.
3. Thecombination withamilling-machine havinga reciprocating bed and a rotating cutter-shaft, of a supporting-arm adapted to be fixed in position above said bed, a stud upon said supporting-arm, a carrying member pivotaily mounted on said stud, clamping devices on said carrying member for securing a link in position thereon, and a lug mounted on said bed and adapted toengage said carrying member to impart motion thereto.
4. In combination,a milling-machine comprising a frame, a horizontal supporting-arm projecting from said frame, a cutter-shaft mounted for rotation beneath said arm, a bed mounted for reciprocation beneath said cutter-shaft and means for imparting movement to said cutter-shaft and said bed, of a linkcutting attachment comprising a supportingarm adapted to be clamped to said horizontal arm, a carrying member pivotally mounted on said supporting-arm, clamping devices on said carrying member for securing a link thereon, and a lug rigidly secured to said bed and adapted to engage said carrying member to impart movement thereto.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
