CONVERTIBLE MACHINE-TOOL.
Specification of Letters Patent.
Patented Nov. 20, 1906.
Application led February 6. 1904. Serial No. 192,442.
To all whom, it may 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, granted to me the 3d of June, 1903.
The present invention may, however, be embodied in other convertible machine-tools and other like tools wholly or in part of the vise type. The leading object of this invention is to facilitate taking apart and renewing the1 feed-screw device forming part of such too s.
The improvement consists in certain novel combinations of parts hereinafter described and claimed.
Two sheets of drawings accompany this specification as part thereof.
Figure 1 is a side view of the machine-tool as compacted for use as a vise or for shipment. Fig. 2 is'an end view projected from Fig. 1. Fig. 3 isa side view-of the machinetool in full and dotted lines, illustrating its use for drilling and for grinding purposes. Fig. 4 represents a horizontal section on the line a b, Fig. 3. Fig. 5 represents a sectional side view of the anvil end of the machinetool, with dotted lines illustrating the operation of a pipe-wrench device. Fig. 6 represents a plan view projected from Fig. 5 with the anvil-top removed. Fig. 7 is a bottom view of the anvil-top detached, and Fig. 8 is a perspective view 'of the nut of the feedscrew device.
Like reference letters and numbers indicate like parts in all the figures.
The anvil-base c and the movable main jaw b of the improved machine-tool are hollow steel castings with base portions 1 and 2, adapted to telescope or slide one within the other, and with lugs c on the base portion 1 of the anvil-base vby which to attach the machine-tool to a bench or the like.
, The anvil-top d is removable for the attachment in its place of a lathe back center or the like and is attached to the anvil-base a in the manner best shown by Figs. 5, 6, and 7, which see. For this purpose said anvilbase a has a flat top 4, provided in a central longitudinal line with notches e and f, the
former, e, undercut, which are snugly filled, respectively, by correspondingly-shaped lugs 5 and 6 on the bottom of the anviltop d When the latter is in place, as in Fig. 5 and in Figs. 1, 2, and 3. Owing to this simple construction, when the vise-jaws 7 and 8 are tightly closed, as in Fig. 1, it is impossible to remove or shake the anvil-top d, and pressure against the face of its vise-jaw 8, as in the drilling operation, Fig. 3, tends to tighten it in place. When the vise-jaws 7 and 8 are separated, the anvil-top d may be freely lifted from its seat 4.
To provide for rigidly tightening the base of the movable main jaw b within that of the anvil-base c 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, oneside 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, Figs. 4 and 5, and a nut i, normally thereon, (shown detached by Fig. 8,) are so attached to the respective parts as to facilitate fitting them and move particularly to facilitate removing them and renewing the nut t, which is the only part exposed to' any considerable wear. The screw 7L 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 by a clamping-screw 13. When the parts are in place, the screw is strongly supported at both ends. When the screw is disengaged from the nut i and said slide 12 is dropped, the screw may be readily withdrawn by means of its hand-wheel 14. The disengaged nut i drops from its place, being supported in working position, as best shown in Fig. 5, between vertical ribs 15, within the hollow base portion 2, and may be economically replaced by a new one when worn. The additional devices carried by said movable main jaw t include a rotatable horizontal spindle at top immediately below the visejaw 7 and provided with a chuck or chucks at 16 to carry interchangeably a drill-bit k or a grinding-wheel l, as represented by full and dotted lines in Fig. 3. The matching cham- ICO ber 17 to admit the point of the drill-bit is formed in the face of the anvil-top d, as shown in Fig. 5.
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. 8, for drilling purposes. Provision is made for driving said spindle at diiierent rates of speed by mounting beneath the spindle in the movable main jaw b two other short rotary shafts 'n and o, to either 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 amultiplying-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. shaftv o provides for an intermediate rate of speed relative to that ofthe crank.
For greater speed or to utilize foot-power a wind-wheel or any convenient motor-a pulley p, Fig. l---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 ofthe movable main jaw. The middle shaft o may be held in place by the gearing or in any approved way.
The suitably-recessed upper portion oi the anvil-base a conveniently accommodates a pipe-and-rod vise, as in previous Jforms of the machine-tool. For this purpose its sides are provided in the present device with holes q, Figs. 1, 3, and 5, the rentrant inner ends of which form one jaw of a pair of maximum capacity. The other jaw 1^ has a matching rentrant face of the same size and slidesbetween the sides of the anvil-base under the pressure of a hand-screw s, working in a nut portion 26 of the anvil-base beneath the anvil-horn 27. To economize time and labor in turning the screw s, the movable jaw r is made substantially L-shaped, as shown in Fig. 5, and is reversible, as illustrated by i'ull and dotted lines in that figure. For large lpipes and rods the jaw r is used, as in full lines in Fig. 5, with its long heel 28, Fig. 5, within an opening immediately above said nut portion 26. By reversing the jaw 1^, so that said long heel 28 is against the screw s, the device is quickly adapted to clamp the smallest pipes and rods with equally little manipulation of the screw. When there is no pipe or rod between the jaws q and 1^, the movable jaw f' can be removed from within the anvil-base at its inner end (shown at the right in Fig. 5) and inserted in reversed position. Owing to the location of the screw s, the shouldered end of the jaw will contact The middle with the end of the screw in either ofthe two positions in which the jaw is shown by full and dotted lines in this figure, and without moving the screw the jaw may be thus quickly adjusted for large and small pipes or rods, and a comparatively limited rotation of this screw is consequently required in clamping large and small pipes or rods.
A socket in the anviletop d to receive a hardy and like attachments is shown at 29 in Fig. 7. This device and other like details not essential to my respective claims hereto appended may be omitted, and other like modifications will suggest themselves to those skilled in the art.
Having thus described said improvement, I claim as my invention and desire to patent under this speciication- 1. In combination, a base adapted to be lXedly attached to a bench or the like and having an open-bottomed hollow base portion, a rotatable horizontal feed-screw mounted in said base portion, a renewable loose nut normally embracing said screw, and a movable main jaw having an open-bot tomed hollow base portion with vertical sides slidable within that of said base and constructed internally with vertical ribs on said vertical sides between which ribs said nut is inserted to attach said movable main jaw to said nut, substantially as hereinbefore specified. j I
