DRILLlNG GLASSWARE.

Patented Aug. 21, 1906.

Application filed July 25, 1905- Sarial No. 271,245.

To all whom it may concern:

-'Be it known that I, JOSEPH G. MARTIN, a resident of Fostoria, in the count of Seneca and State of Ohio, have invente a new and useful Improvement in Machines for Drilling .-Glassware;-'and I do hereby declare the fol lowin to be a, full, clear, and exact descrip- I tion t ereof.

a 'plan .view of my machine, one of t e dle-bearingsbeing broken away. Fi 2 is a,

:with vertical be more arms 4, whic My invention relates to a drilling-machinal and more especially to a multiple-spindle machine for'drilling hollow glassware and similar' articles. i

The object of the invention is to improve machines of this character in details of ar-. ra ement and construction hereinafter descri ed. a z

In the accompanying drawings, Fi re is spincentral vertical section. Fig. 3 is a si e view,

' on an enlarged scale of a portion of the frame and one of the spindle-bearings and Fi 4 is a longitudinal section of one of the chuc s;

- My machine will'be rovided with any suitable base, such as s own at 1, carryin the standard or frame 2, which is provided arinfis 3 and with three or project radially outwardly and upwardly. These arms at their ring 15 are all formed of a single upper ends are provided with horizontal 'faces 5, upon which rest bearing members 6 for the drill-s indles 7. As many bearing members 6 wi be provided as there are slpiil li- 'dles in the machine, the particular mac illustrated having six radially-arranged spindles. The bearin members 6 have two bearing-sections 8 an 9 united by side members or bars 10. The several bearing members are connected by means of the braces 1 1 which "are shown as cast integral withthebearing "members; This, however, is not necessary, as they may be formed of suitably secured together. At their inner ends the bearing members are provided with tr 'sverse openings .12 for receiving the beveled' pinions 13 on the drill-spindles '7. At

theirextreme inner ends these bearing members are provided'with arms 14, which project inwardly and downwardlyf and are connected to a rin 15 for receiving a suitable s shown in the drawings, the 11, arms 14, and

bearing members 6, braces integral separate pieces I handle for operating the same.

casting; but obviously they may be formed of separate pieces, if desired.

- The drill-spindles 7 are held in the bearing members by means of

caps

16 and 17, the latter being provided with a hood 18 for covering u the beveled pinion 13. The several bevele pinions 13 are engaged by a toothed rim or crown-gear 20, provided with spokes or arms 21, curvin downwardly and connecting the toothed nm with the hub 22. The latter is suitably secured to the upper end of a hollow shaft 23, mounted in the bearings 3 in the base-frame 2. This shaft is provided with a beveled gear 24, which engages a similar gear 25 on a driving-shaft 26, mounted in a bearin formed in one side of the frame 2. The sha t 26 may be driven by an suitable means or in any suitable Way. spindles will be fed toward the work yield.

ingly., For this purpose I- provide spiral.

springs 28, surrounding the drill-spindles and bearing at their outer end against washers 29, seated against the outer bearing members 8 and at their inner ends bearingagainst col-- he drillcollar 32 is provided with a downwardly-pro jecting lug or .pin 34, which extends into a slot 35, formed in the arms 4 or bearing members 6, as the case may be, so as toprevent saidcollar from turning with the s indle.

The machine-frame is provided wit only three arms 4. Consequently every alternate bearing member 6 will have a slot 35, formed in the bottom connecting member 36, as indicated on the right-hand side of Fig. 2.

The several ins 34 project through camslots 38, forme in a ring 39, suitably mounted'on the arms 4 and in the bearin members 6. This ring at one side is provi ed with a The several cam-slots 38 project on an angle, as shown in Fig. '1,- so that when the ring is turned all of thespindles will be simultaneously withdrawn. At their outer ends the (cam-slots are provided with straight ortions 42,- so thatwhen the spindles have l ieen fully withdrawn they will be held in that position, the pins 34 then resting in the portions. 42 of'the slots. In order to feed the spindles forward, the ring is rotated slightly, so as to cause the pins to clear the straight portion 42 of the cam-slots and come into the inclined portions thereof. The springs 28 will then continue to feed the spindles inwardly. One of the braces 11 is provided with a depressed portion 43, as indicated in Fig. 1, to makeroon'i for the handle 40.-

The work-holder is so constructed as to hold the work yieldingly. It is shown as a sleeve 45, suitably secured in the ring 15 .by means of collars or nuts 46 and provided with a cushioning-lining 47, which may be formed of cork, rubber, or other suitable cushioning material. The hollow lass article is shown at 48 as projecting own into the work-holder while t e drills are operating thereupon.

In drilling glassware and the like it is nec: essary to supply water to the part being drilled. For this purpose I supp y suitable 4 water-pi es 50 for directing a jet of water against t e article at each drill. In order to permit this water to drain away, Isecure to the inner end offlthe bearing-members 6 a suitable basin or cup 51, provided in its bottom with an opening 52, which communicates v with the opening 53 in the hollow shaft 23, so

that the water and grit will be conducted away from the machine.

The drill itself is shown at 54. It is comprised of a suitable body of abrading material. It may be held in any suitable chuck secured to the, inner ends of the spindles 7,

that shown comprising asplit sleeve 55, having an external'tapered threaded face for recelving an integral tapered nut 56. Any other chuck will answer the purpose equally aswell. g

The articles to be drilled are inserted in the machine from above and all of the operating mechanism is underneath, so "as to give easy access for the insertion and removal of the articles. Provision is made for draining .away the water and grit, so that the latter cannot get into the bearings or gears. In fact, all of the gearing is well housed and protected' from the water and grit.

The 0 eration of the machine will be understoo from Y the foregoin description; Themachine as a whole is simp e of construction, contains a minimum number of parts, and provides forfeeding the drills yieldingly as well as holding the article yieldingly, so. f

that breakage is reduced to a minimum.

Various changes may be made in the form and'location of the several parts without departing from the spirit of my invention. a
