FLUTING TOOL.
Application filed December 26, 1924. Serial H0. 758,108.
This invention relates to tools and mechanisms for use in producing grooved or fluted work. The invention is especially concerned with. the manufacture of drawing rolls of the type used in textile machinery. For example, a spinning frame includes several pairs, usually three, of rolls between which the roving is fed toward the spindle, and these rolls revolve at progressively increased speeds so that as the roving travels from one pair of rolls to the next pair in front of 1t, the fibres in the roving are drawn out into positions more nearly parallel with each other. In order to enable these rolls to grip the roving, they have grooves formed in them and extending longitudinally thereof. Heretofore the grooves have usually been cut roughly by planing and then finished by stoning and lapping. The planlng operation as heretofore performed leaves the walls of the grooves very rough so that the finishing of the grooves is very expensive.
It is the chief object of the present invention to improve the tools and mechanisms used in producing grooved work of this general character with a view to expediting this 0 eration and reducing the expense of manu acturin-g' grooved rolls and similar work.
The nature of the invention will be readily understood from the following description when read in connection with the accompanying drawings, and the novel features will be particularly pointed out in the appended claims.
In the drawings,
Figure 1 is a perspective View of a tool and holder therefor embodying the invention in the form at present preferred;
Figs. 2 and 3 are cross sectional views on the lines 22 and 3-3, respectively, Fig. 1* and Fig. 4 is a plan view of the lower edge of the grooving tool.
Figs. 1, 2 and 3 show a drawlng roll 2 of a common form in the process of being rooved. The tool shown in the drawings for performing this operation consists of a plate or flat bar of steel including an elongated body ortion 3 with an ofi'set portion 4 exten ing from one side of the body portion, these two portions having a common medianplane. The lower edges of these two portions are substantially parallel and they are both approximately V-shaped in cross section. The ends of the body portion 3 preferably are slanted backwardly, as shown, and the ends of the edges of this part are ground to form two cutting faces 5 and 6, respectively. The ends of the edge of the offset 4 also are ground at a backward inclination to form two cutting faces 7 and 8. A double ended tool thus is provided, each end including two cutting faces which are in alinement with each other and are adapted to work-simultaneously in a single groove.
In using this tool it preferably is mounted in a holder, such as that" shown at 10, the holder being slotted to receive the tool and being provided with a bolt 12 which clamps the tool firmly in the holder in any desired position of adjustment. The grooving operation is usually performed in a planing ma chine, the roll 2 being supported on the travelling table of the planer, and an indexing mechanism being provided to rotate the tool step by step between successive reciprocations of the table. The mechanism for supporting and indexing the work may be substantially like that used heretofore. The grooving tool is supported by the holder 10 in an inclined position, as indicated in Fig. '1, so that the two cutting faces which are being used operate in the same groove. These faces are ground so that they are laterally inclined in o posite directions, as indicated in Fig. 4. onsequently, they divert the chips which they out toward the opposite lateral faces of the tool. It will be observed that as this tool moves relatively forward with reference to the work, the left-hand edge 13, Fig. 2, of the cutting face 5 will make a cleaner out than the opposite edge, due partly to this inclination of the cutting face and partly to the inclination of the tool. In fact, the latter edge really does not out. For the same reason the right-hand edge 14, Fig. 3, of the rear cutting face 7, will make a clean out while the opposite edge of this face does not cut. Consequently, by oppositely inclining the two cutting faces in the manner described, the tool will cut a groove having very clean walls. With this arrangement each stroke of the tool or work cuts a groove which is smooth on both sides. After grooves have been formed by indexing the roll through a complete revolution, the operations just described preferably are tral offset also provides relativelylong cutrepeated to cut the grooves deeper. During the latter operation most of the metal removed is taken from the opposite side walls of each groove.
When the entire periphery of the roll has been grooved, the roll is then ground or stoned and the grooves are lapped. The finishing operations can be performed much more quickly on a roll grooved as above described since the walls of the grooves are left relatively smooth by the planing operation. My invention eliminates entirely the necessite directions so that they will direct chips toward the opposite faces of said plate.
2. A grooving tool comprising a plate-including a body portion with an offset projecting at one side thereof, the edge of said offset being substantially parallel with the adjacent edge of said body ortion, and said edges being substantially -sha ed in cross section, and cutting faces at t e adjacent ends of said edges, said faces being laterally inclined in opposite directions.
3. A grooving tool comprising a plate insity for filing the grooves and effects a very cluding an elongated body with a central substantial reduction in the expense of finishing the rolls. A better roll alsois produced.'
Due to the fact that the tool is doubleended it is simply necessary to reverse it in its holder when one pair of cutting faces become dull. The elongated body with a centing edges so that the faces can 'be ground back for a long distance before the tool is worn out and rendered useless.
While I have herein shown and described the best embodiment of my invention that I have so far devised, it will be appreciated that this embodiment may be modified in some particulars without departing from the spirit or scope of the invention. For example, the edge of the offset 4 need not have exactly the same contour as the edges of the main body 3 of the tool, such an arrangement being provided for the purpose of cut ting a groove of a different shape or of dividing the work more evenly between the two cutting faces. In fact, the shape given to these edges necessarily will vary somewhat with the nature of the work to be performed.
I may also provide the tool with three cutting faces at each end instead of two, the forward face making a roughing out while the two following faces act successively to smooth up the opposite walls of the groove made by the first face.
Having thus described my what I desire to claim as new is:
1. A grooving tool comprising a plate including a body portion with an offset projecting at one side thereof, the edge of said offset being substantially parallel with the adjacent edge of said body portion, and cutting faces at the adjacent ends of said edges, said faces being laterally inclined in oppoinventi on,
offset projecting at one side thereof, the edges of said body at said side being substantially parallel with the edge of said offset, and" cutting faces formed at the ends of said edges, whereby two cutting faces are presented at each end of said plate.
4;. A grooving tool comprising a plate including an elongated body with a central offset projecting at one side thereof, the edges of said body at said side being substantially parallel with the edge of said offset, all of said edges being approximately V-shapcd in cross section, and cutting faces formed at the ends of said edges, whereby a pair of cutting faces is presented at each end of the plate, the individual faces of each pair being laterally inclined in opposite directions so that they will direct chips toward the opposite faces of said plate.
5. In an apparatus of the character described, the combination of a grooving tool comprising a plate having an offset portion at one side thereof with the edge of said offset extending substantially parallel-to the adjacent edge of said body, said edges being approximately V-shaped in cross section, cutting faces at the ends of said edges, and a holder for supporting said tool with said edges in inclined positions and the cutting faces arranged to cut a single groove in the work.
6. A grooving tool comprising a plate having two cutting faces of approximately V-shaped outline adapted to act simultaneously on the work, said faces being located one in advance of the other so that they will cut in a. single groove, said faces being laterally inclined in opposite directions and of sufficient Width to direct the chips which they out toward the opposite faces of said plate.
