LATHE ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 568,612, dated September 29, 1896. Application filed January Z0, 1896. Serial No. 576,198. (No model.)
To all whom t may concern:
Be it known that I, WALTER H. GRIPMAN, of Sioux Falls, in the county of Minnehaha and State of South Dakota, have invented a new and Improved Lathe Attachment, of which the following is a full, clear, and exact description.
The object of the invention is to provide a new and improved lathe attachment which is simple and durable in construction, very effective in operation, and designed forcutting gears, grooving taps and reamers, splining shafts, cutting T-slots in chucks, and for various other Work done on a milling-machine.
The invention consists principally of a baseplate adapted to be secured to the tool-block, a casing mounted to turn on said base-plate and adapted to be secured thereto,and a shaftframe fitted to slide in said casing and provided with bearings for the milling-tool shaft.
The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
. Figure 1 is a side elevation of the improvement. Fig. 2 is a plan viewof the same. Fig. 3 is a transverse section of part of the improvement on the line 3 3 of Fig. l. plan view of the base-plate, and Fig. 5 is an enlarged plan view of the milling-tool.
The improved lathe attachment is provided with a base-plate A, adapted to be fastened 4on the tool-block of the lathe, said base-plate being provided for this purpose with a bolt B, extending centrally from the base-plate to engage the nut held on the tool-block. On the under side of the base-plate A is arranged a guiding-shoulder A', fitting into a slot in` the tool-block. On the top of this base-plate A is mounted a casing C, having a central integral pivot C', fitting into a correspondingly-shaped central recess A2, formed in the top of the base-plate A, as is plainly shown in Fig. 3. This recess A2 is also adapted to, receive the head of the bolt B.
In the top of the base-plate A is formed an annular T-slot A3, engaged by the heads of Fig. LLis a the bolts D, engaging the casing C, to permit of securely fastening the casing to the baseplate after thecasing is turned to the desired position. The casing C is provided with a longitudinally-extending bearing or guideway C2, in which is fitted to sl'ide an arm E', extending from the frame E, the outer end of saidarm being tapped for engagement with a screw-rod F, collared in an extension C3, projecting from the casing C. On the eXtreme outer end of the screw-rod F is secured a suitable handle F to permit the operator to turn the screw-rod F, so as to move the arm E', and
con sequently the frame E, inward or out Ward, according to the position of the work held between the centers of the lathe.
The frame E is provided with a suitable bearing for the shaft G, carrying the millingtool H, said shaft being also provided with a beveled gear-wheel I, in mesh with a beveled gear-wheel J, secured on a shaft J', j ournaled in a bearing K, secured on a bracket K, having a split hub K2, engaging a projection E2, formed on the frame E and being part of the bearing for the shaft G. A clamping-screw L on the split hub K2 serves to clamp the latter in place on the projection E2.
.On the shaft J is secured a pulley J 2, adapted to be connected by a belt with an overhead pulley, for imparting a rotary motion to the shaft J', and by the gear-wheels J and I to the shaft G, carrying the milling-tool H. The lower reduced end of the shaft G is preferably journaled in a bearing E3, removably held on the frame E.
The peripheral surface of the base-plateA is preferably provided with a graduation, and the casing is provided with a graduationmark in the form of an arrow to permit of setting the said casing to a desired degree, according to the work under treatment.
Now it will-be seen that by the arrangement described a desired feed can be given to the milling-tool H by the operator turning the handle F accordingly, it being understood that the entire attachment is adjustable on the lathe in a transverse direction and moves with the feed-carriage in the usual manner.
In cutting a beveled gear the attachment may be set at any desired angle, and the bracket K may be turned on the projection IOO E2, so as to bring the pulley J 2 in alinement with the pulley above. For cutting T-slots in base-plates or chucks the cutter-shaft G may be placed parallel with the center of the lathe. The pulley J2 may be taken oif the shaft J and fastened on the shaft G in case it is convenient to drive said shaft G directly from the overhead pulley. lVhen the attachment is used for cutting gears, then the bearing E3 is not needed, and thus permits of conveniently removing the cutters or millingtools.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A lathe attachment, comprising a baseplate adapted to be secured to a tool-block, a easing mounted to turn on the base-plate and having means for securing it in position thereon, a shaft-frame tted to slide in the casing, a screw-shaft carried by the casing and arranged to engage the shaft-frame, a tool-shaf t j ournaled transversely on the shaftframe, a gear-Wheel carried by the toolshaft, a bracket mounted adjustably on the shafti'rame, and a shaft journaled in the bracket and provided with a gear-Wheel meshing with the gear on the tool-shaft, substantially as set forth.
2. A lathe attachment, comprising a eircular baseplate having means for securing it to the tool-block and provided with a series of peripheral graduations, a casing mounted to turn on the baseplate and provided with an index to traverse the graduations on the base-plate, said base-plate being provided in its upper surface With a central circular recess and said casing being provided on its under side With a projecting circular pivot to engage the recess in the base-plate, the baseplate being provided in its upper face with a circular T-groove, bolts carried by the casing with their heads engaging said T-groove, a bearing secured to the top of the casing, an arm fitted to slide in the bearing, a frame carried on the arm, a tool-shaft journaled in the frame, means for driving the tool-shaft, and a screw collared on the casing and connected to the arm, to move the same, substantially as set forth.
