FRANK H. OAKMAN AND HENRY A. AXTELL, OF SHELBURNE FALLS, MASSACHUSETTS.
TOOL FOR HOLDING DISKS FOR DRILLING.
Specification of Letters Patent.
Patented July 20, 1909.
Application filed August 1, 1907. Serial No. 386,539.
To all whom it may concern:
Be it known that we, FRANK H. OAKMAN and HENRY A. AXTELL, citizens of the United States, residing at Shelburne Falls, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Tools for Holding Disks for Drilling, of which the following is a specification.
This invention relates to tools for gripping and holding disks while being drilled or otherwise worked upon; and the object is to provide a tool, in the nature of jig, which is simple in construction, convenient and effective in operation, and adapted to securely hold disks of different sizes for the purpose of drilling or performing other work thereon.
In the accompanying drawings, Figure 1 represents a top plan view of the tool containing a disk. Fig. 2 represents a longitudinal vertical section. Fig. 3 represents a top plan View with the cover plate of housing removed. Fig. t represents a top plan View of a pair of detached holding jaws.
The tool 1 is provided with a suitable housing for containing the operating parts and is constructed of a comparatively thick bottom plate 2, having side flanges or strips 3, and an upper end flange or strip i, an outer end strip 5, a cover plate 8 and two swinging keeper strips 6, having rounded lower outer corners (3. The strips 6 overlap the strips 2-3 being wider than the latter as indicated by dotted lines in Fig. l and by full lines in Fig. 3, and form guide-ways for the detachable holding jaws 12, being pivotally connected to strips 3 by pins (3 and held in place by removable pins 7. By removing pins 7 the strips (5 may be swung outward, as shown in Fig. 3, for permitting the jaws 12 to be detached from, or placed in chamber 10 of the housing. The cover-plate 8 slightly overlaps the lower jaw when in place as shown in Fig. 2. Evidently the flanges, or
In the chamber 10 are pivoted a pair of levers 15, by pins 17, with their short, outwardly turned arms 16 in position to bear against the lower edge of the lower jaw 12, and with their long arms extending downward in position to be thrust outward into the recesses 3* in the flanges 3. At the lower end of the housing are connected a pair of hand levers 18 by pins 19 and having inwardly curved short arms 20 projecting be tween the ends of lovers 15. Evidently the operation of these hand levers in connection with levers 15 will impart a powerful thrust upon the lower jaw 12 and a very slight movement will sufiice to grip and securely.
hold a disk in the jaws. The operation of engaging, or disengaging a dlsk can be quickly performed.
A disk being placed on the semicircular shoulders 14L and supported thereby, the hand-levers 18 will be contracted, causing the slidable jaw to grip and securely hold the disk. It will now be subjected to the action of a boring bit, which will pass through it into the opening 9. The disk having been drilled or bored will be released but still supported by theshoulders, and by'a turn of the tooll may be deposited in any desired receptac e.
The device may be modified in details of construction without departing from our invention.
Having described our invention, what we claim and desire to secure by Letters Patent 1s The combination with a housing having a guide-way, of a pair of jaws therein, one of which is slidable, for holding an article, a pair of pivoted levers bearing at their short arms on the slidable jaw and a pair of handlevers for actuating said j aw-levers, substantially as described.
In testimony whereof we afiix our signatures in presence of two witnesses.
