FILING, SAWING,AND GRINDING MACHINE.
Application filed November 2, 1926, Serial No. 145,845, and in France May 14, 1926. Renewed J annary 17,
The present invention relates to a filing,
sawing and grinding machine principally characterized by the fact that when it is employed as a filing machine, the tool, which in this case consists of a round or rats-tail file, may receive simultaneously a vertical alternating movement and a continuous rotary movement. Under these conditions the file works with its entire surface, thus aug menting the efiicienc' of the tool.
The drives for tie alternating vertical movement and for the rotation of the tool,
alternating vertical movement, and as a.
grinding and piercing machine, when it gives the spindle only a rotary movement.
In the drawings accompanying the present specification:
i Fig. l. is an elevation and profile view of the machine forming the subject-matter of the present invention;
Fig. 2 is a front elevation of the machine;
Fig. 3 is a perspective view with parts in section and parts removed from the shafts, of the mechanism controlling the rotary movement; v
Fig. 4 shows on a larger scale partly in section and partly in elevation, the device controlling the alternating movement;
Fig. 5 is a front View of the same device;
Fig. 6 shows in plan the mounting of a piece of work on the plate of the filing machine, the said piece being machined for a semicircular profile;
Fig 7 is a plan View of the plate, upon which is mounted a piece of work to be out into a spur gear wheel;
Fig. 8 shows in plan the mounting of a piece of work on the plate of thefiling machine, this piece being machined to present a rectilinear face.
As can be seen in Figures 1 and 2, the machine is moved by an electric motor 1 usually fixed to the base of the frame, but it may alternatively receive its movement from an adjacent transmission shaft.
The frame that supports the various members consists of a base 2, into which is fixed a cylindrical column 3, along which can slide the sleeves of the plate and of the clamping chuck.
Upon the column 3 is fixed the bracket 4, which sup orts the various members concerned in t e rotary drive. 1
The form and general construction of this frame, as just described and as illustrated in the accompanying drawings merely constitute one example of the construction of the support of the various members of the machine and it will be understood that this support may be given quite a different form and general construction without the characteristics of the invention, which areall contained in the devices which are about to be described, being any way affected thereby.
'lhodriving device for rotating the spindle carrying the tool is constructed in the following manner, as illustrated in Figures 1, 2 and 3.
A pulley 5 keyed on to the motor shaft transmits the movement from the latter toa pulley 6 which rotates integrally with the spindle 7, upon which the tool 53 is mounted. This transmission is effected through the medium of a belt 8 which passes over, guide pulleys '9, 10, the position of which is adjustable by displacing their shaft 11 along a guide 12, these pulleys 9 and 10 admitting moreover of being fixed in the selected position by tightening a screw controlled by the.
handle 1 i The ratios between the pulleys 5 and 6 are judiciously selected sothat the spindle may receive a rotary movement corresponding to the work to be effected or to the nature of the metal to be worked. With this end in ,view the extremity of the spindle can rebers according to the position of the motor or of the transmission shaft.
Thedevice that gives the tool an alternating vertical movement is the following (Figures 1, 2, 1 and The base 2 carries sleeve 5% either cast on to it or fixed on to it by any suitable means. This sleeve serves as a bearing for a shaft 55, on to which is keyed a pulley 16, which can receive a rotary movement from a pulley 17 fast to the motorshaft through the medium of a belt 18.
To the other extremity of the shaft 55 is keyed a chain pinion 19 which drives an endless chain 20 which elsewhere engages with a pinion 21 loose on a trunnion the positionof which is adjustable in a slot 23 con centric with the axis of the trunnion and cut in a shoulder 2a of the sleeve 54.
transmits to the rod 28, with which it i virtually integral, an alternating movement.
The other extremity of the rod 28 has a cap 29 which is pivoted to a ring 30, virtually inte ral with a screw-threaded rod. 31.
The latter engages in a hole in the llshaped member 32, the two extremities and 34 of which are bored out along a suitable diameter in order to lit over the spindle 7, hearing at the same time upon the shoulders 35 and 36 carried by the spindle.
The position of the screw-threaded rod 31 in the member 32 can be adjusted and fixed by means of nuts such as 37 and 37.
The screw and nut device 29 which is carried by the rod 28 on the one hand, and the screw-threaded rod 31 on the other hand therefore enable the length of the rod to be adjusted, and, consequently, the position of the fork S3, 34 on the spindle, which amounts to adjusting the ends of the travel of the tool.
Finally, the member 32 is constantly urged upwards by a spring 38 attached by one of its ends to a hook 39 virtually integral with the member and by its other end to a hook 4E0 prolonged by a screw-threaded rod 41 the position of which can be varied upon a bracket 42, which is itself movable in a sleeve 43 integral or virtually integral with the frame.
The alternating vertical movement of the member 32 is controlled by that of the rod 28, and its stroke is equal to the distance which in vertical projection separates the extreme positions of the pivot 25. In this alternating movement the member 32 drives the spindle 7 without opposing the rotation .of the latter, by the fork formed by its an tremities 83 and 34C.
The tool therefore receives, 111 con unction with a continuous rotary movement, an alternating vertical movement, this latter having a certain flexibility in consequence determination of the ends of its travel by r the length of the connecting rod 28 and the adjustment of the amplitude of the move ment by displacement of the pinion 21 in the slot The machine as just described enables pieces of work to be machined by filing along various outlines, the entire surface of the round lile being utilized.
By way of example Figures 6, 7 and 8 of the drawings illustrate the mounting upon the plate of the machine, of pieces of work to be machined along various profiles.
111 Figure 6 is shown a piece of work 14,
the extremity of which it is desired to file along a semicircular curve. I The piece of work is pivoted to the plate by a pivot a5 integral or virtually integral with the clamping chuck i6, the position of which is maintained fixed by any suitable means, such for example as the hook 47 shown in the figure.
The extremity of the piece of work e4 after being roughly shaped is presented to the file by one of its sides in such a manner that the distance from the axis to the moving periphery of the tool is equal to the semicircular radius of the curvature of the piece of work, and the workman limits himself to rotating the piece as the work progresses.
Figure 7 illustrates the work of filing the extremity of the teeth of a spur pinion 4:8, the piece of work being successively pivoted to the plate on the axes 49 and 49of the arcs of circles along which the teeth are cut.
Finally Figure 8 shows under treatment a piece of work 50, the face 51 of which is to be straightened, the said piece being guided by an angle-iron 52 fixed to the plate and being pushed forward as the work progresses.
It is easy to understand that by applying these various devices and following previously prepared templates it will always be 2 possible with the machine to file pieces of work to any outlines, the movements to be given in the course of the work to the pieces to be machined admitting moreover of being given either by hand or by any suitable automatic arrangement.
If the belt 8 is removed or shifted on to a Sill pulley turning loosely upon the spindle, the rotary movement is suppressed and only the alternating movement of the tool remains.
It is thus possible to utilize flat files for certain Work or to employ the device as a sawing machine.
If, on the contrary, the alternating move ment stopped, the machlne can function,
as a drilling or boring machine or as a grinding machine, the descending movements of the spindle admitting of being attained by any suitable means.
The machine which has been described above and which is illustrated in the accompanying drawings only constitutes one constructional form of the invention which is more particularly characterized by the com bination of the alternating and rotational movements, the operation of which has been explained.
It is quite understood that the shapes of the various members, and also their relative positions on the frame, may be different from those shown in the drawings and that in particular a filing machine can be constructed in which the drives of the alternating and rotational movements would be lo cated at the lower part of the machine under the plate without thereby departing from the characteristics of the invention.
