LATHE ATTACHMENT.
Specification of Letters Patent.
Patented J une 13, 1916.
Application filed March 4, 1916. Serial No. 82,120.
To all whom it may concern:
Be it known that I, EDWARD O. ROGERS, a citizen of the United States, residing at Latrobe, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Lathe Attachments, of which the following is a specification.
My invention relates broadly to lathes and has particular reference to improvements in means for holding the cutting tool or tools thereof, so that it will not be subjected to undue strains, when the machine is being used for heavy work.
A further object of the invention is to provide means of the above mentioned character, which is simple in construction, inexpensive to manufacture, strong and durable.
Other objects and advantages of the invention will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same, Figure 1 is a side elevation of a lathe, having my invention applied thereto, Fig. 2 is a side elevation of one tool prop and associated elements, Fig. 3 is a detail section taken on line 33 of Fig. 2, Fig. 4 is an end elevation of the lathe, showing my invention applied thereto, and, Fig. 5 is a side elevation of the upper tool and prop.
In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates a horizontally arranged base of the lathe, upon which is mounted to move longitudinally thereof, a carriage 11. Mounted to move longitudinally of the carriage and transversely of the base are slides 12 and 13 which have depending lugs 14 and 15 respectively. These depending lugs have screw-threaded openings provided with right and left screw-threads for receiving portions 16 and 17 of an operating screw 18, having right and left screwthreads, as shown. The operating screw 18 is turned by a crank 19 and it is obvious that its rotation will simultaneously move the slides 12 and 13 toward and away from each other.
The numeral 20 designates the work and elements 21 and 22 the means for holding the work and rotating it upon its longitudinal axis, as is customary.
The sllde 12 has a tool holder 23 bolted or otherwlse rigidly secured to its top, withm wh ch is arranged a lower horizontal tool or cutter 24, which may be clamped thereln by means of a bolt 25.
The numeral 26 designates an adjusting bolt, havlng screw-threaded engagement within an opening formed in a bracket 27 carried by the slide 12. The bolt 26 is adapted to contact with the outer end of the tool 24, thus preventing its longitudinal movement. Arranged'beneath the tool 24 ad acent its forward cutting end and at a right angle thereto is a lower vertical prop 2:7, havlng a base 28, bolted or otherwise rigldly attached to the bottom of the slide 12 as shown at 29. As clearly shown in F g. 3, the upper end of the prop 27 is provided wlth a preferably V-shaped groove 30, receivlng a V-shaped portion 31 formed upon the lower side of the tool 24 at lts cutting end. It is thus apparent that the prop 27 engages the tool 24 at or near 1t s cutting end, and being arranged at a right angle thereto, holds the same against lateral movement in a highly satisfactory manner. As there is no connection between the prop 27 and tool 24 other than a contact, it is obvious that the prop does not interfere with the longitudinal adjustment of the tool with respect to its slide, upon which it is mounted.
Bolted or otherwise rigidly mounted upon the coacting slide 13 is an over-hanging arm 30, to the outer end of which is rigidly secured an upper vertical prop 31. The lower end of the prop 31 is arranged above and contacts with the cutting end of an upper tool 32, which has its outer end held with in a tool holder 33, bolted or otherwise rigidly secured to the slide 13, as shown at 34. The lower end of the prop 31 is provided with a V-shaped groove identical with the groove 30 and the upper portion of the tool 32, at its cutting end, has a V-shaped portion identical with the V-shaped portion 31, to enter the groove. It is thus apparent that the prop 31 is arranged at a right angle, tothe tool 32 above and at its cutting end, whereby the same securely holds the tool against improper lateral movements.
In the operation, the work is mounted upon the lathe in the usual manner and is caused to rotate upon its longitudinal axis. By proper manipulation of the operating screw 18, the tools 24 and 32 are brought into contact with the work and operate within the same cut. The props hold the tools against bending or lateral movement, thus taking undue strains from the same.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
Having thus claim 2- The combination with a slide of a lathe having an attaching portion and a laterally projecting arm extending inwardly beyond the attaching portion for a substantial distance, of atool having one end arranged upon the attaching portion of the slide and provided adjacent its opposite cutting end and upon the side thereof remote from the described my invention, I
Gopies of this patent may be, obtained for work with respect to the direction of rotation of the work with a longitudinal tongue, adjustable means for clamping the tool to the attaching portion so that the tool may be shifted longitudinally with respect to the slide, a prop arranged at substantially a right angle to the tool upon the side thereof remote from the work With respect to its direction of rotation and secured to the free end of the arm and provided with a transverse groove extending longitudinally of the tool to receive the longitudinal tongue thereof for forming with the tool atongue and groove connection, whereby the tool is braced against movement in the direction of rotation of the work and longitudinally of the work in opposite directions but is free to be longitudinally adjusted toward and away from the work.
In testimony whereof I affix my signature two witnesses.
in presence of EDWARD C. ROGERS. Witnesses:
