C, A. JAKOBB- WORK SUPPORT.
APPLICATION HLED SEPT-25; I9I9.
Patented Dec. 14, 1920.
UNITED STATES PATENT ()FFIQE.
CHRISTIAN A. JAKOBB, OF NEW YORK, N. Y.
WORK-SUPPORT.
T 0 all whom it may concern:
Be it known that I, CHRISTIAN A. J AKOBB, a citizen of the United States, and a resident of New York, in the county of Kings and State of New York, have invented certain new and useful Improvements in Work- Supports, of which the following is a specification.
The present invention relates to worksupports for metaland wood-working machines, such as for instance sawing machines, drilling machines, etc.
The main object of the present invention is to provide a work-support or work-table that may be readily and quickly set at clifferent angles to the tool, for instance a saw or drill.
Another object of the invention is to produce a work-support of the character described, which is adapted for manufacture on a commercial scale, or in other words one which is not so diflicult to make as to be beyond the reasonable cost of such a contrivance.
A. further object of the invention is to devise a work-support of the character mentioned which is simple in construction, efiicient in operation, durable in use, convenient to handle and the parts of which may be set, when mounted for instance upon a sawing machine, during the cutting operation, thereby permitting the plane of travel of the work in relation to the line of travel of the saw to be adjusted either step by step or continuously, according to the require ments.
With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claim and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claim, without departing from the spirit or sacrificing any of the advantages of the invention;
One of the many possible embodiments of the invention is illustrated in the accompanying drawings, in which:-
F1gure 1 is a central, vertical section taken through a work-support constructed in ac- Specification of Letters Patent.
Patented Dec. 14, 1920.
Application filed September 25, 1919. Serial No. 326,473.
cordance with the present invention; and Flg. 2 1s a top plan view thereof.
In the drawings, the numeral 10 indicates a base, for instance in the form of a table, upon which the work-support is mounted. The work-support comprises two members, denoted by the numerals 11 and 12, the member 11 being stationary, while the member 12 is shiftable in relation to the said first-mentioned member. The memher 11 is made in the form of a spherical socket, that is set within an opening 13 in the base plate 10, it being provided with a flange 14; within a recess 15 in the upper face of the said base plate, screws 16 or other fastening means serving to hold the socket in fixed position upon the said base plate. The exposed face of the flange 14 is preferably flush with the upper face of the base plate 10. The member 12 of the support is in the form of a spherical body, that is partly disposed in the socket and adapted to be turned therein. The spherical body 12 is of such dimensions that it projects normally above the base plate 10 and is provided with a flat table portion 18, through which extends an aperture 19. This aperture is centrally disposed on the table portion 18, it being reamed on the underface of the said table portion to permit a tilting of the spherical member 12 in relation to the socket 11 with the tool extending through said aperture. In alinement with the aperture 19, both the spherical member 12 and the socket 11 are provided with large openings 20 and 21, respectively, thrgugh which the tool is adapted to extenc.
In the drawings a tool in the form of a jig-saw 22 is shown, said saw being stretched in a suitable frame, one element of which, denoted by the numeral 28, is disposed above the base plate 10, while its other element, indicated at 24, is located below the same. This frame may be reciprocated in any suitable manner, the means for reciprocating the same being not shown, as they do not form part of the present invention.
In use, the work is placed upon the table portion 18 upon the spherical member 12, and the latter shifted to present the work at the proper angle in relation to the line of travel of the saw 22. When the table portion 18 of the work-support extends horizontally, the cutting proceeds at right angles to the lineof travel of the saw, while when tilted a cut at an oblique angle will be obtained, that is to say a bevel will be formed on the work. The work is'usually fed to the saw by hand, and so is also the spherical member 12 held in the desired po sition.
It'- is obvious that, while herein the support has been shown inconnection with a jigsaw, it may be made use of on drilling machines, etc., just as well.
Attention is also calledto'the fact" that, inasmuch as the spherical member 12 is held in position-by hand, the plane of travel of the work may be adjusted in relation: to the line. of travelof the saw while the cutting operationis being. performed, that is tosay the said plane of travel may be varied continuously or step by step, as required, or it may be maintained duringthe entire cutting. operation, according; to the character of the work. to-be done.
' The work-support herein. described is especially suitable-for jewelers use, although not limited thereto. It is particularly adapted for scroll. work and. knife-edge workfor fine platinum jewelry, wherein the beveling operation requires a continuous change of the plane of travel of the work.
In a work-support, the combination with a base plate having an opening and a recess in its upper face around said opening, of a spherical'socket set within said opening provided with a flange within said recess, the exposed face of said flange being flush with the upper face of said base plate, and a spherical body partly disposed; within said socket projecting. normally abovesaidibase plate and being provided with. a flat table portion, said table portion having" a central aperture reamed on the underface of said table portion, said spherical body and. said socket having openings larger than said: aperture to permit ofthe passage of at'ool therethrough and of an angular shifting of said spherical body in said socket in all directions.
Si ned at New York, in: the" county of New ork and State'offNew York,this 20th day of: September, 1919.
