`PB0FILING MACHINE.

Application led January 9, 1920. Serial No. 350,424.

To rrl uzhmnz't may concern.'

Be it known that I, JOHN J. THACHER, a citizen of the United States ot' America, residing at lVethersfield, in the county of Hartford -ind State of Connecticut, have invented new and useful Improvements in Profiling Machines, of which the following is a specification.

This invention relates to metal Working machines and more specifically to profiling machines wherein a rotary cutter is c aused in operation to follow a path conforming to a pattern mounted on the machine and it is the particular object of the invention to generally improve machines of this type.

It is a further object of the invention to generally improve the tool lubricating systern of metal cutting machines and to provide improved means for more readily disposing of the chips as they are formed during the operation of the machine.

It is a further object of the invention to niount the driving means and cutter-supporting means iii an improved manner and to provide an improved and novel means and arrangement for supporting and adpisting the cutter supporting saddle on its guide rails.

It is a further object of the invention to improve the accuracy and utility of profiling machines by mounting the former pin blocks in an improved manner whereby the same may be more easily and accurately adjusted and firmly secured in adjusted positions.

lVith the above and other objectsin view, which will appear as the description pro- (reeds, the invention will now be described bv reference to the drawings wherein:

l Figure 1 is an isometric view of a protiling machine embodying the present invention.

Fig. 2 is an end elevation thereof partially broken away to illustrate certain iinproved lubricating features, the cutter-supporting saddle being shown in section on the line 2-2 of Fig. 3.

Fig. 3 is a front elevation of the saddle and cutter-supporting heads, the improved former pin blocks being shown as mounted in the heads. A

Fig. 4 is a plan yiew of the body of the machine showing the large chip and oil basin and the integral parts thereof.

Fig. 5 is a vertical longitudinal section thereof on the line 5 5 of Fig. 4.

Fig. 6 is a vertical transverse section taken on the line 6 6 of Fig. 4.

Fig. 'i' is a detail plan view of oneof the cutter heads having the improved former pin blocks mounted therein. the mounting of one of these blocks being shown in, horizontal section taken on line 7 7 of Fig. 8.

Fig. 8 is a detail front elevation of the same, showing one ot` the block mountings in vertical section taken on line 8-8 of Fi. 7.

eferring more specifically to the drawing by reference characters, 1 indicates the base of the machine and 2 the supporting column on which is mounted the arch or saddle supporting member 3 comprising the rails 4 and As shown in Fig. 1, I prefer to make the member 3 as a piece separate from the base 1 and to secure the said member to the hase abutments 3 by means of bolts 3. lt should be noted that these abutmciits are entirely within a large chip and oil basin to be hereinafter described. The saddle G is mounted to slide along the rails and vertically slidablymounted thereiii are the cutter heads 7 which support the cuttcrspindlcs 8 and the usual former pins. As is usual in this type of machine, the saddle may be moved along the rails by means of a rack and pinion mechanism 9 and an operating handle 10. The Work is adapted to he supported on the table 11 which may be moved on the Ways 12 in a direction at right angles to the movement ot' the saddle by means of a handle 12. I provide the table with the usual trough 1l and furthermore prefer to provide an overhanging lip 11 leading from the trough whereby the table guideways are kept tree from chips and cutting lubricant.

As heretofore stated, one object of my invention is to provide improved means to care for the oil or lubricating compound and chips coming from the work fable and in this connection it should be understood that throughout the specification the term oil is used in a broad sense to indicate a lubricant or lubricating or cutting compound.

This improved construction is shown in Figs. 1, 2, 4, 5 and 6 wherein I have illustrated a large chip and oil basin 13 preferably inte ral with the column 2 and entirely surrounding the work table and its supporting guides. As before stated, the rail member 3 is entirely supported within this basin on abutments 3. Also the rails and cutter operating parts mounted on the rails are directly over the basin whereby any oil dripping from such parts or down the rail supports falls directly into the basin. The base of the machine preferably rojects forward as at 14 wherein is provi ed an oil reservoir 15 with one or more ports leading thereinto. I preferably provide two such ports and mount a removable chip screen 16 within each and directly above each of the screens. as shown in Figs. 1 and 2, I support a removable chip pan 17. such construction permitting quick and easy removal of the chips and easy access to the reservoir for cleaning or other purposes. It should be noted that the screen 16 prevents any chips from dropping into the reservoir 15 Where the pan 17 is removed. The chip and oil basin 13 preferably extends to the front and rear as shown in Fig. 2- in such manner as to project entirely over the base of the niachine and beneath the work tabl(J and the inner surface of such basin at all points slants toward the channels 18 leading respectively into the removable chip pans. It should be clear that the novel features herein disclosed may be embodied in machines of designs other than the one shown herein. one of the foremost features of the invention being the large chi and oil basin supported beneath and exten ing outside of the operating table and a removable oil-draining chip pan so located relative to the basin that it may readily be removed to dump the chips therefrom. During the operation of the machine,` the chips as well as the lubricant are caught by the basin 13 as they fall from the table 1l, the arrangement preferably being such that the basin performs this function in all positions of the table. It will also be noted that the basin extends beneath all the operating parts of the machine in such manner that any oil dripping from such parts falls into the basin where it is carried to the reservoir 15. I also prefer to provide bafile- plates 19 and 19 at each side of the machine lwhereby any oil dripping from tue outer portion of the rail is deilected into the basin. It will be clear that the shape ofthe basin 13 is such that the chips and lubricant are Washed from the higher levels 12% to thc lower levers 13" and down the channels 18 into the removable pans 17 where the lubricant is drained off leaving the chips in the ans. The chips may be easily removed by ifting the pans through the space or opening beneath the channels 18 at the front of the machine and dumping the chips therefrom. The lubricant is used over again by being pumped from the reservoir by a pump 20 and connections shown in Figs. 1 and 2.

In profiling machines of the present type, it. is essential that all operating parts be as rigid and free from looseness and lost motion as possible. lVith such end in view, I provide a novel means and arrangement for supporting and adjusting the saddle on the supporting rails in an improved manner. This means comprises a taper gib 21 which preferably is of a length to span the entire length of the saddle 6. As shown in Figs. 1

and 2. I form a preferably integral elongated projection 22 on the saddle, such projection being adapted to cooperate with the upper rail-engaging portion 23 in supporting the saddle. I mount the gib 21 between this projection and the upper surface of the lower rail and I provide means, preferably a screw 24 as shown, for adjusting the gib longitudinally to take up any wear or looseness of the saddle on the rail. It will of course be understood that the lower surface of the projection 22 is tapered or inclined to conform to the taper of the gib. By supporting the major portion of the saddle on one rail und by performing all the adjusting operations on a single rail by means of a single elongated gib, the mounting of the saddle is rendered stronger and more accurate than on like machines heretofore used.

As a further means for preventing vibration and rendering the machine more accurate, I prefer to mount the driving drum directly on the body of the machine rather than on the rail member 3 as has been the usual practice heretofore. As shown in Fig. l, I secure the brackets 25 directly to the machine body' at 25' by means of suitable bolts. The driving drum 26 is rotatably supported in these brackets and through the belts shown drives the cutter spindles. As has been heretofore stated, the cutter-supporting member 3, as Well as the table 11, is also mounted directly on the machine body. It will be seen that by this construction, all the main movable parts of the machine are mounted separately on the body whereby the vibratory effect of one on the other is reduced to a minimum, such feature being of particular importance in a. machine of the type illustrated.

As a further means of improving the construction of the present machine, I provide a novel form of mounting for the former pin blocks, such mounting being shown in all the views of the. drawing as a part of the present machine. As is usual in this type of machine I provide a former pin mounting on both sides of each cutting tool` such pins serving to operate on a right or leftl hand pattern respectively. Referring particular` 1,4ee,e 1 i 1y to Figs. 7 and 8 wherein I have illustrated the former pin construction in detail, S illustrates the tool spindle mounted in the vertically slidable tool head 7. Eachside of the head 7 is recessed as at 27 within which I preferably mount the-former pin block 28, each block having a former pin as 29 secured therein b means of the clamping bolts 30. Each b ock is preferably recessed laterally as at '31, such recess being adapted to receivev therein means, such as a pin or bolt 32, whereby the bloclg is prevented from vertical movement within the recess 27 but may be readily removed when desired. l

I secure the block in the recess 27 by a clamping means including a clamping screw threaded into the head 7, the arrangement of the clamping means being such that the block is crowded or wedged into the ,recess in a manner to fully prevent any lateral movement thereof. his clamping means preferably comprises a curved clamping head* 33 mounted on the bolt 34, such head being adapted to engage the block adjacent one corner thereof and to force the blocksecurely into the opposite corner of the recess. As shown in Fig. 7, I also preferably chamfer off the block as at 35 and the adjacent corner of the head as at 36 whereby to form a recess to receive the clampin/ghead 33 in a' we'dging position therein" As a means for adjusting the block laterally relative to the tool spindle 8, I prefer herein to provide a taper gib or wedge, as 37, the side of the block adjacent to the gib being likewise inclined or tapered to fit the gib. I also prefer to provide a positive means for adjusting the gib longitudinally and as sucha means for this purpose I herein illustrate a screw 38 threaded into the block and having a positive engagement with the gib, as by means of a flange 39 engaging a notch 40 in the This construction provides a positive and accurate means for adjusting the gib in both directions longitudinally. After the block is adjusted to the desired position, the clamping bolt 34 is tightened and the block thereby forced tightly into the opposite corner of the recess and against the gib 37. As will be observed. this novel block mounting construction provides for a very line and accurate adjustment of the block laterally in the recess, prevents the block from any vertical movement. and provides a means whereby the block may be securely clamped against any lateral movement in the bead 7.

From the above description taken in connection with the drawing it is thought that the general operation of the improved machine and the advantages of the present improvements thereon will be readily understood. However while I have illustrated the invention as being carried out by certain mechanism shown in the drawing, it should be clearly understood that the invention is not limited to such structure shownbut may be varied within the scope of the appended claims.
