THOMAS J. MOORE, OF ALTOONA, PENNSYLVANIA.
TOOL-HOLDER.
Specification of Letters Patent.
Patented Oct. 10, 1905.
Application filed December 15, 1904:- Serial No. 237,006.
I 0 all whom it may concern:
Be it known that I, THOMAS J. MOORE, a citizen of the United States, residing at Altoona, in the county of Blair and State of Pennsylvania, have invented new and useful Improvements in Tool-Holders, of which the following is a specification.
This invention relates to that type of toolholders which are specially designed for use in connection with metal-working machines, such as planers and slotters, and a number of types of machines employing a rigidly-supported tool which must be capable of adjustment to a variety of positions to accommodate different classes of work and different lines of out.
To this end the invention contemplates the construction of tool-holder comprising simple and practical means for quickly setting the tool to any of a variety of positions without removing the tool from its support. In this connection the invention also provides positive and effectual means for securely clamping the tool in any of its adjusted positions.
With these and other objects in view, which will more readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts, which will be hereinafter more fully described, illustrated, and claimed.
The essential feature of the invention involved in the means for setting the tool into variable positions and for clamping it in any of such positions is susceptible to structural change without departing from the scope of the invention; but a preferred embodiment of the latter is shown in the accompanying drawings, in which- Figure 1 is an elevation of a tool-holder constructed in accordance with the present invention. Fig. 2 is a longitudinal sectional view through the clamping-bolt and the element-s associated therewith, showing more plainly the engagement of the setting-washers with the tool and the formation of the transverse tool-opening in the body portion of the bolt. Fig. 3 is an elevation showing the setting-washers adjusted to positions for holding the tool clamped in a plane parallel to the tool-carrying bar or post. Fig. 4: is a detail in perspective and projected face view of one of the adjustable setting-washers. Fig. 5 is a side elevation in detail of one of the setting-washers.
Like reference-numerals designate corresponding parts in the several figures of the drawings.
In carrying out the invention the means for adjusting and clamping the tool may be applied -to any of the ordinary types of tool supports or carriers, such as usually employed in connection with metal-working machines, so for illustrative purposes there is shown in the drawings a portion of an ordinary tool bar or post 1, which is provided at its toolsupporting end with a bolt-hole 2, accommodating therein the threaded shank portion of a clamping-bolt 3. The extremity of the threaded shank portion of the bolt 8 projecting beyond one side of the tool-carrying bar 1 receives thereon a binding-nut a, which impinges against the side of the carrying-bar to provide for firmly clamping the tool in its set position. At the side of the tool-carrying bar or post 1 opposite the binding-nut 4 the clamping-bolt is formed with an enlarged shouldered head portion 5, formed at its outer end with an annular clamp-flange 6 and provided therein with atransverse tool-receiving opening 7 which is preferably cut on diagonal or oblique lines, whereby the said opening is of an outwardly-flaring width toward both ends.
The double-flared tool-receiving opening 7 of the clamping-bolt accommodates therein the tool or tool-bit 8 of any of the conventional forms employed in connection with metalworking maohines and is designed to be set into variable positions and clamped in any of such positions through the medium of a pair of adjustable setting- washers 9 and 10, cooperating therewith, and also with the head portion 6 of the clam ping-bolt. The adjustable settingwashers 9 and 10 are loosely mounted on the cylindrical head portion 5 of the clampingbolt and are respectively disposed at opposite sides of the tool or tool-bit 8. One of the washers (designated by the numeral 9) preferably has one end thereof held in matching relation within an annular washer-seat 11, provided in one side or face of the toolcarrying bar 1, while the plain end or side of the other Washer '10 registers flush within the angle at the inner side of the clamped flange 6 of the clamping-bolt.
When the bolt is loosened through the loosening of the binding-nut 4, ample space is provided between the opposing surfaces of the two clamping-washers to permit the tool 8 to be adjusted lengthwise in the opening 7 and also tilted to any desired angle. To provide for securing the tool in variable positions, each of the washers 9 and 10 is of a varying Width and at the side thereof next to the tool is formed With a plurality of tool-engaging seats 11. These seats are made up of a number of shouldered steps of different sizes and also include straight, inclined. and curved surfaces which in the aggregate provide for every practical position required of a tool in a metal-working machine, particularly of the planer and similar types. The tool-engaging sides of the washers 9 and 10, which are made up of the plurality of toolengaging seats referred to, may be properly said to be cut obliquely, and these seats of the separate Washers 9 and 10 are arranged in an opposing relation, so that each washer may be individually adjusted to bring the proper tool-engaging seat against one side of the tool, while the opposite washer is correspondingly adjustable. After such adjustment of the washers the clamping-bolt is tightened up, thereby securing the tool firmly in its adjusted position. The tool-engaging portions of the washers 9 and 10 are roughened to firmly grip the tool.
From the foregoing it is thought that the construction, operation, and many advantages of the herein-described tool-holder Will be readily apparent without further description, and it Will be understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of the advantages thereof.
Having thus described the invention, What is claimed, and. desired to be'secured by Letters Patent, is
In a tool-holder of the class described, the combination with a tool-carrying bar, of a clamping-bolt ad justably mounted in said bar and having a flanged head portion provided with a transverse tool-opening flaring in width toward opposite sides of the bolt-shank, said tool-opening being adapted to adjustably receive therein the tool, and a pair of separate setting-washers mounted on the bolt respectively at opposite sides of the plane of the tool, and each provided with an irregular oblique side having a plurality of tool-engaging 't'aces made up of shouldered steps.
In testimony whereofl atlix my signature in presence of two subscribing witnesses.
THOMAS J. MOORE.
