CHUCK FOR .STEM WARE.
Application filed August 13, 192,5. Serial No. 49,972.
My invention relates to chucks for stem ware and has for its object to produce a chuck which will support stem ware rotatably ina vertical position and in which the ware may be quickly and accurately centered regardless of any slight differences in the contour of successive articles.
In the accompanying drawings forming part of this specification Fig 1 lshowsya front view of a chuck embodying my inven-v tion and F ig. 2 shows a section on a line 2 2 of Fig. 1. 'I he chuck comprises a block 10 which is secured on the bottom end of a vertical shaft 11 by means of a set screw l2. A fork 13 extends outwards from the block beneath the shaft. l/Vithin the fork there is an inset 14 which is substantially horseshoe shaped and has its upper surface slanted so that it will properly support the foot Aof a sten'nned glass article. Beneath and parallel with fork 13 there is a fork, 15 provided with an inset 16 which is likewise shaped substantially like a `horseshoe and has its inner surface sloped to lit the bowl of a stemmed glass article. Arising froml each side of fork 15 there is a pin 17 and from the rear of the fork a similar pin 18 extends upward` These pins extend through perforated lugs 19 on block 10. There is a little more strain on the rear pin than there is on the side pins, and, in the structure shown, the rear pin is provided with a steadying bushing 20.
In the use of this chuck the lower fork is raised and a stemmed article 21 is insertcd into the chuck from the front, the stem entering openings in the front of the forks. Thereafter the article is lowered until its foot 22 rests upon the inset 14, and finally the fork 15 is lowered until the inset 16 rests upon the bowl 23 of the article. It will be readily understood that the inset 16 may be lowered until it rests upon the bowl of the article regardless of any slight variation in the contour of successive articles, so that the article may bequickly and accurately positioned in the chuck. The insets may be easily removed and replaced by differently shaped insets where radically different articles are to be treated.
It will be readily understood that if the chuck were to be used in other than a vertical position the fork 15 could be pressed away from fork 13 by means of an inten posed spring, or, if desired for any'reason,
thelower fork might be fixedly attached to block 10 and fork 13 might be made slidable towards and from fork 15, in which case, fork 13 would be pressed away from fork 1,5 by interposed springs, unless the chuck were to be used in the rreversed position from thaty in which vit is shown in the drawings, in which case fork 13 might be pressed downwards sufiiciently by gravity.
Other departures from the `precise construction shown might be made without departing from the scope of the invention as defined in the appended claims.
lhatI claim is:
1. A chuck for stemmed ware comprising a fork adapted to Contact the upper surface of the foot of an article, a parallel fork adapted to contact the lower surface of the bowl of an article, means connecting the two forks for sliding movement towards and away from each other and means constantly tending to separate -the forks.
2. In a chuck for stemmed ware a fork having a removable inset adapted to fit the upper surface of the foot of a stemmed article, a forkV having a removable inset adapted to fit the undersurface o-f a bowl of a stemmed article, means connecting the two forks and holding them parallel while allowing sliding movement of the forks towards and away from each other and a yieldifnglmeans constantly tending to separate the .or r. f
3. In a chuck for stemmed ware, a vertical shaft, a block attached to the lower end of the shaft, a fork extending beneath the block, pins parallel with the shaft extending through perforations in the block and a second fork supported upon the lower ends of said pins.
l. A chuck for stemmed ware comprising a vertical shaft, a block attached to the lower end of the shaft, a fork extending from said block, an inset in said fork adapted to support the foot of a stemmed article in alignment with the shaft, pins parallel with said shaft and extending slidably through perforations in said block, a second fork supportedupon the lower ends of said pins and an inset in said second fork adapted to' rest upon the bowl of a stemmed article and hold said bowl in alignment with said shaft. In testimony whereof I have hereunto signed my name to this specification.-
ALVAH C. PARKER.
