FRANK GUNN FARNHAM, OF HONESDALE, PENNSYLVANIA.
DEVICE FOR MANIPULATINGLGLASS ARTICLES.
Application filed February 25, 1905, Serial No. 247,362.
To all whom it may concern:
Be it known that I, FRANK GUNN FARN- HAM, a citizen of the United States, residing at Honesdale, Pennsylvania, have invented certain new and useful Improvements in a Device for Manipulating Glass Articles, of which the following is a s ecification.
My said invention re ates to improvements in the means for dipping cut glass articles in an acid bath.
It is well known that the finishing and polishing of cut glass articles is rendered much cheaper and more effective if, after cutting, they are dipped in a bath of suitable acid or acids, but in thus dipping great care must be used in preventing the acid from coming in contact with the inner or uncut surface of the article' Just why the contact of the acid with the uncut surface of the glass will pit it and hence produce detrimental effects, while securing beneficial results in its application upon the exterior surface is a mooted question. Such however is the case.
In a companion application filed by me on the 3d day of February, 1905, Serial Number 244,047 I have described and claimed an apparatus for thus dipping articles having smooth flaring mouths. There are a large number of articles, however, such as vases, cream pitchers and sugar bowls and others too numerous to mention in which the mouths are contracted instead of flared and are of such shape as to preclude the forma tion of an air tight connection, and hence the use of the means disclosed by my present application.
It is, therefore, the object of the present invention to provide a simple, convenient, and effective device for manipulating such articles, by which they may be dipped in the acid without allowing contact thereof with the interior of the article and without danger to the workman.
A further object is to provide for rapidity in manipulation and immunity from danger of breaking or damaging the articles oper ated upon.
With these and other objects in view the invention includes an expansible acid proof member, adapted. to be expanded within a glass article, with manipulating means.
The invention further includes an inflatable acid proof member having attached means for i inflating and manipulating the same.

Renewed June 29, 1907. Serial No. 381,547.
The invention further includes an air forcing device with a removable inflatable acid proof member carried thereby; and finally the invention includes the various features of construction and arrangement of parts hereinafter described and particularly pointed out in the claims.
The invention is illustrated panying drawings in which- Figure 1 is a sectional view of the complete apparatus, Figs. 2 and 3 are detail views, Fig. 4 is a view of the wrench, Figs. 5 and 6 are detail views or modifications, and Figs. 7 and 8 are res ectively a sectional elevation and a sectiona plan of a modification adapted for manipulating a number of articles at a time.
Referring by reference characters to these drawings the ordinal 6 designates a cylinder of any suitable acid proof or acid resisting material which is provided with a removable tubular plug 7 threaded into its lower end and a removable cap 8 threaded upon the upper end. l/Vithin this cylinder is removably located the barrel 16 of an air pump, the lower end of which is closed by the valvecarrying part 15, hereinafter more fully described, while the upper part carries a removable cap 17. The exterior diameter of the pump barrel is less than the interior diameter of the cylinder 6 so as to leave an annular space, and the pump barrel is centered in the cylinder by the depending annular flange 17' of the cap at the top and the laterally extending flange 15 of the part 15. lVithin the pump barrel works a piston rod 26 carrying a suitable pump piston 27 at one end and having a suitable operating handle 28. Air is admitted to the pump barrel through alining openings 9 in the caps 8 and 17 I prefer to place a packing disk 5 between the caps S and 17 as shown, which will of course be provided with corresponding openings. The openings in the cap provide means by which a spanner may be used to unscrew the cap when the pump barrel is to be removed.
The valve plug or member is provided at its lower end with an annular flange 10 having an annular groove 10 in its upper face. A washer 14 encircles this member between flange 10 and the lower end of the cylinder 6,
' has a corresponding, but
in the accomand this washer oppositely located, groove 10 9. At 18 is shown an inflatable bag or body,
preferably of rubber having a thickened or beaded edge designed to be clamped in the grooves and between the flange. It will be understood that this bag is designed to be placed within the cut glass article to be dipped and air forced into it by the air pump to cause it to be expanded within and securely hold the cut glass article, as indicated in Figs. 5 and 6.
While the bag will accommodate itself within certain limits to varying sizes and shapes of glass articles, some of the articles differ so widely as to make it necessary or desirable to make different sizes or shapes of bags and have them removable and interchangeable. For this purpose all the bags are formed with uniform beaded mouths. When a bag is to be removed and a fresh one substituted the pump barrel 6 is removed from the cylinder and a long tool or wrench 19 inserted, its angular lower end engaging an angular opening 7 a in the plug 7 whereby said plug may be unscrewed to allow the mouth of the plug to be released. When the mouth of a fresh bag has been sprung over the flange the plug will be screwed back into the cylinder to clamp it firmly in place and. the wrench removed and the pump put back into place when the device is ready for use.
In order to avoid undue fraying or wearing of the bag during its insertion into and removal from the article I prefer to' make it smaller in diameter than the mouth of the article to be manipulated, the elasticity of the bag allowing it to expand to hold the article as indicated in Figs. 5 and 6. As a convenient means of supporting the valve, I provide the cap or part 15 with a threaded boss 20 upon which is screwed a cap 21. A valve spindle 25 guided at one end in an opening 24c in the cap and at its other end in the central opening of the cap 15, carries a disk 22 upon which rests a rubber valve 22 The lower end of the cap is perforated to provide air passages as shown.
It is necessary to provide means for letting the air out after the articles have been dipped for the purpose of releasing them. To provide for this I form lateral openings 7 in the upper portion of the plug 7, which upper portion is rabbeted or recessed so as to allow said openings to communicate with the annular space between the cylinder and the pump barrel. The cap or member 15 has notched edges as shown at 15 so as not to interrupt the air communication. On the cylinder 6 near its upper end, I provide a tubular extension 11 which is threaded to receive a threaded cap 12 having a milled head by which it may be turned and an opening 12. A washer 13 between the cap and the threaded tubular projection 11 effects an air tight joint. It will thus be seen that after the article has been dipped the bag may be quickly deflated to effect its removal by unscrewing the cap until the opening 12 clears the end of the tubular projection when the compressed air will at once escape up through the base between the cylinder and pump barrel. In some cases I may make the cylinder 6 out of rolled sheet metal instead of cast. In this event, I prefer to cap the cylinder 6 with a thicker piece of metal 11 and permanently fastened thereto and I then screw in and solder the valve tube 11 thus securing an air tight joint. I also cap the bottom in a similar manner. The object is to save weight by using a thin outer tube and have an air tight joint and a wall thick and strong enough to take a thread which will not wear out in a short time.
While the inflatable members or bags may be made regular in shape, there are some articles, such as pitchers for instance, which while they would be effectively held by a bag of regular contour, would yet expose some portion of the inner surface to the action of the acid. To avoid this, I may provide a bag with an irregular portion 18" to fit the irregular contour of the glass article as indicated in Fig. 6. I may in some cases find it desirable to strengthen the upper portion of the inflatable bag by reinforcing it with a sheet of similar material as indicated at 18 Fig. 3.
lVhile for dipping large and heavy articles, it is not wise to manipulate more than one at a time, I may provide for dipping a plurality of smaller articles such as cream pitchers, sugar bowls and the like at a single operation. Such a form of the invention is disclosed in Figs. 7 and 8. In this form I use a single cylinder and pump barrel con nected to a hollow base 1, which for the purpose of lightness and saving in metal, I may form in spider shape with a plurality of radiating arms C corresponding in number to the number of articles which it is desired to dip at any one time. These arms, have passages 2 leading from the aperture in the central boss 3 to which the cylinder is connected. The outer ends of the arms have depending annular flanges 41 into which the threaded plugs 7 are inserted, the inflatable members or bags being held by these in substantially the same manner. In this event, instead of providing a separate valve at the passage leading to each inflatable bag, provide a single check valve at the base of the pump cylinder.
When rubber bags are in constant use their surfaces after a time become saturated with acid. When so saturated, if time is not given for evaporation, the glass will smear or become clouded on the inside. The practice is to have a good many balls or bags, laying aside those which have been in use until the acid evaporates and substituting clean ones. It follows that a rubber bag as shown will from constant use be likely to smear to some extent. In order Imay,
therefore to make it unnecessary to change a bag except at rare intervals, I use a very thin inexpenslve rubber protecting tube 18 about the same diameter as the deflated bag which I draw over it covering the equatorial section for afew inches, see Fig. 3. Should this become saturated it is quickly removed for evaporation and another substitued.
Having thus described my invention, wnat I claim is 1. A portable device for dipping glass articles, comprising a manipulating member including an air-forcing device, and an inflatable member connected to said manipulating member and adapted to be inflated by the air-forcing device, substantially as described.
