CONVERTIBLE MACHINE-TOOL.
Specification of Letters Patent.
Patented Nov. 20, 1906.
Original application filed February 6 1904, Serial No. 192,442. Divided and this application filed February 9, 1906. Serial No. 300.306.
To all whmn it 711.00g concern:
Be it known that I, THEODORE F. TIMBY, a citizen of the United States of America, and a resident of Alma, in the State of Michigan, have invented a new and useful Improvement in Convertible Machine-Tools, of which the following is a specification.
This invention is primarily additional to the improvement in convertible machinetools that is the subject-matter of Letters Patent of the United States No. 701,424,
In common with the tool claimed in said Patent No. 701,424 the present improved tool preferably and conveniently comprises an anvil-base adapted to support alternatively a detachable anvil-top having at its inner end a chamber to admit the point of a drill-bit or a back-center attachment for lathework, a movable main jaw, a horizontal shaft mounted in said movable jaw and constructed and arranged to carry interchangeable bit and grinding-wheel chucks or to form a lathespindle, and connections between said anvilbase and movable jaw including a horizontal feed-screw.
The distinguishing object of the present invention is to provide for the different speeds of the improved convertible machinetool by a simple combination of spur-gear- 1ng.
A sheet of drawings accompanies this specification as part thereof.
Figure 1 is a side view of the machine-tool as compacted for use as an anvil or for shipment. Fig. 2 is an end view projected from Fig. 1. Fig. 3 is a side view of the machinetool in full and dotted lines, illustrating its use for drilling and for grinding purposes; and Fig. 4 represents a horizontal section on the line A B, Fig. 3.
Like reference letters and numbers indicate like parts in all the figures.
The anvil-base a and the movable main jaw b of the improved machine-tool constitute what may be termed its frame parts and are hollow steel castings with base portions 1 and 2, adapted to telescope or slide one within the other, and with lugs 0 on the base portion 1 of the anvil-base, by which to attach the machine-tool to a bench or the like. An anvil-top d is superposed upon said anvil-base a and is constructed with one of a pair of vise-jaws 7 and 8 at its inner end. To
provide for rigidly tightening the base ofthe movable main jaw 1) within that of the anvilba'se a at will in the several positions of the former, Figs. 1 and 3, and especially when the machine-tool is adjusted for use as an anvil or for shipment, Fig. 1, one side of said base portion 1 of the anvil-base a is provided with a clamping device g, which may be in the form of a thumb-screw, as shown, impinging against the side of said base portion 2 of the movable main jaw b. For moving said parts a and b with reference to each other a longitudinal feed-screw h, Fig. 4, and a nut i are attached to the respective parts.
The screw h has cylindrical portions 9 and 10 at its respective ends, fitted to bearings in the base portion 1 of the anvil-base a, and a circumferential groove 11, adjacent to the principal bearing 10, interlocks with a slotted slide 12, held in place within said base portion. The additional devices carried by said movable main jaw I) include a rotatable horizontal spindle j at top immediately below the vise-jaw 7 and provided with a chuck or chucks at 16 to carry interchangeably a drillbit 7c or other attachments interchangeable therewith, especially a grinding-wheel Z, as represented by full and dotted lines in Fig. 3. A matching chamber 17 to admit the point of the drill-bit is formed in the face of the anvil-top d, as shown in Fig. 3.
A hand-crank m, preferably provided with a clamp-screw 18, may be applied directly to the protruding rear end of the spindle j, as shown in full lines in Fig. 3, for drilling puroses. Provision is made for driving said spindle j at different rates of speed by mounting beneath the spindle in the movable main jaw 19 two other short rotary shafts n and 0, toeither of which the crank m may be applied, and forming or making fast thereon and on said spindle the successive wheels and pinions 19, 20, 21, and 22 of a multiplying-train of spur-gearing. For the greatest speed suitable for the grinding operation the crank m is applied to the lower shaft n, as shown in dotted lines in Fig. 3. The middle shaft 0 provides for an intermediate rate of speed relative to that of the crank. For greater speed or to utilize foot-power, a wind-wheel, or any convenient motor a pulley p, Fig. 4, may be attached to either of the shafts n or 0 or to the spindle The lower shaft n is conveniently held in place against longitudinal displacement by a collar 23, Fig. 4, pinned thereto behind its principal bearing 24, and a supplemental bearing 25 is conveniently formed behind the collar within the hollow base portion 2 of the movable main jaw. The middle shaft 0 may be held in place by the gearing or in any approved way.
The suitably-recessed upper portion of the anvil-base a conveniently accommodates a pipe and rod vise, as in previous forms of the machine-tool. For this purpose its sides are provided in the present device with holes g, Figs. 1 and 2, the rentrant inner ends of which form one jaw of a pair. The other jaw 1" has a matching rentrant face and slid es between the sides of the anvil-base under the pressure of a hand-screw 8, working in a nut portion26 of the anvil-base beneath the anvil-horn 27.
All features and combinations herein shown or described which are not covered by the claim hereto appended are hereby disclaimed in favor of my application for Letters Patent filed the 6th day of February, 1904, Serial No. 192,442, of which the present application is a division.
Having thus described said improvement, I claim as my invention and desire to patent under this specification A convertible machine-tool, having, in combination, a frame part constructed with bearings for a horizontal spindle and two subjacent shafts, a rotatable spindle provided with a chuck for carrying a drill-bit and attachments interchangeable therewith, rotatable shafts mounted in the other of said bearings, a train of multiplying spur-gearing connecting said shafts and spindle, and means for rotatin the spindle attachable at will to said spind e direct or to one of said shafts, such spindle and shaft having outer driving ends adapted to interact interchangeably with such rotating means in the several positions of the latter.
THEODORE F. TIMBY.
