i IMPROVEMENT IN ORN AMENTING ARTICLES OF GLASS 0B OTHER VITREOUS MATERIALS.

' r'o ALL wnoM 1m MAY coNcnnN;

Bc it known that I, ANTON Scuwir'rnr., of 182 Fulton street, in the city, county, and State of New York,

have invented a new and useful Improvement in OrnamentingArticlcs of Glass or Other Vitreous Material; and,

I hereby declare that the following is a i'ull, clear, and yexact description thereof, which will enable those skilled ixi't'lre art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawng- Figure 1 represents a plan or top view of t-lie mechanism which may be used'in carrying out this invention,

n partlyfin sect-ion.

Figure is a side elevation of thesame.

.Figure 3 is a transverse verticalsection of the same, takenrin the plane indicated by the line a: sn, fig. 1.

vFigure 4 is'a partial plan of the mechanism necessary to impart motionto the rotating cutter.

Similar letters of reference indicate corresponding parts.

This invention consistsin giving to the cutter used in ornamenting articles of glass or other vitreous materiel a. motion towards and from the work by hand at the will of the operator, while the work is secured to a movable spindle o-carriage irrsuch amanner-thnt the operator is enabled to produce lines orinarks of uniform or of variable thickness, while the motion imparted to the work by the mechanism insures perfect regularity o f said lines or marks. The tool used in this operation has a rotary motion besides the motion which is imparted to it by the hand of the operator, and it is secured in suitable tool-bearer, which is so constructed that it allows of imparting to the tool all the requisite motions.

-Thc mechanism which is represented in the drawing, andlwhich may be used advantageously in carrying 3 ont my invention, is any ordinary engine turning machine or rose engine, the-working parts of which are supported-hy' a table or platform, A, and which rests upon legs, B, at a convenient height for the operator, who is to: stand on the floor C.y The spindle E of said rose engine has its bearings in a frame, F, which has a transverse .oscillating motion o 1 the table, and this oscillating motion of thc frame, as well as the longitudinal motion of thespindle, is governed by the action of a rosette, D, and guide, G or, if desired, the frame may be made stationary-and the spindle so arranged that it has only a revolving motion, and in this case ln. chuck is attached to uid-p-iindle, which is provided with a 'diagonally-moving carriage, so that a revolving and also a rectilinear motion can be imparted to the work secured to said chuck. After the article to be ornamentedshas been secured tnilthe spindle or chuck, it is exposed to the action of a rotating cutter or tool, II. This tool may be made .of a composition of cmer'y withvliquid silex or any other`- suitable material, or it may be made of steel or any @other material, according tothe nature of'the surface on which the ornamentation is to bc produced. For the purpose of cutting lines into the sui'iace'of an article oi' glass au'rcmerynvheel is the best, and this wheel or tool is secured .to a spindle, Lywhich is composed of two parts, 5 c, one sliding within the other. The tubular shaft b carries o"n one end the tool H, and its other end has its bearing in a head, d, to which a longitudinally sliding motion can be imparted in the guide-ways e by means of a sct-screw,f, or in any othersuitable manner. l The solid part c of the spindleT has its bearing in a swivel head, g, which turns on n pivot, h, and it (the part e) extends into the tube nearly to its extreme end, as clearly shown in iig. 1`of the drawing. By 'turning the set-screwf, the tube i5 is made to'=sli(le on the solid rod c, and the spindle I is lcngthened or shortened according to the spot where the tool is to act. The guidewaysgc ofthe head d move in a dove-tailed segmental groove, z', which forms a portion of a curve described in such al manner that in turning the .swivel head the head b will be caused to move in the curved groove, and by moving said head d in the curved groovcthe swivelheadg will be compelled to turn on its pivotwithout binding.. Thepivot -L of the swivel head screws into a. standard, j,. which rises from a slotted plate, J, and .another standard, c, rising from the same plate, supports theeurval groove z' in which the carriage moves, which forms the guide-rest for the head d, as shown in fig. 2. The platevl J is perforated with a cross-shaped slot, 1c, and it is secured te the table A by a screw, Z, whichl passes through' a T-shapcd slot, m, in the table, and is fastened by aunt or in any other convenient manner. Byv the combined action of theslots 7c and m the plate J can be adjusted to any desirable position, and the tool can be readilyf brought to bear on the side or end of the article to be ornamcntcd.J The end of the solid part of the spindle I extends through the swivel head g, and bears the pulley n and a belt, lo, extending from nfast-and-loose pulley,l

.regularity of the lines or marks is insured.

ppl, over the pulleyn serves to impartmotion to the spindle I and tool H. The pulleys ig: plare mounted 'on a shaft, K, which hasts bearingsV in the boxes q g g, ajletaehcd-fplah view of which is shown in g. 4. The boxes g'q are close together, and secured. to a plate, r, which is fastened down to the iioor screws, s, passing through semicircular slots, t, 'so that by taking hold of the outer end of the shaft K, the boxes, together'witlr the plate r, can be turned in either direction. The box g, which supports the shaft K near its outer end, moves,

in scmicircular guide-ways et, forming a portionV of a circle described from the centre of the plate 'r, so that the several boxes q q gr will describe concentric circles when the shaft swings round the centre of said plate. A

thumb-s`crew, inpassing through a flange projecting from the box q. serves to fasten the latter and with it the shaft K in the desired position. By these means the shaft K can always be brought in the proper relation towards the shaft I which carries thel tool. It must be remarked, however, that this arrangement can `be altered,

and various and different means can be employed to transmit the motion from the shaft K to the shaft I, .such as cog-wheels and extension-rods with universal joints; and I do not wish to confine myself, therefore, to the precise mechanism shown in the drawings, but reserve the right to change the same as may' be desirable. The shaft K derives its motion by means of a belt, ai, from a pulley, b2 on a shaft,lc'l, which in the drawings is represented below the Boor C, but which may be arranged in any other convenient position. iMotion is imparted to the shaft by a belt, di', from4 a pulley,`c", on the countershaft f2, which has its bearings in suitable hangers under the table A, and to which motion is imparted bya'hhelt, g2, froml the driving-shai`t h2. belt, il, extending from a pulley, j, on the; counter-shaft, imparts motion to the spindle of the rose engine.A

AThe operation is as follows: The article to be ornainented is secured to the end of the spindle E in the ordinary manner, and after the engine has been adjusted according to the desired ornamentation, it is started. The tool, which rotates by means of the belts and pulleys hereinbe'fore spccilied, is brought in contact with the surface of the articlet'ol be ornamented, its position being regulated by the hand of the operator, which grasps the tool-holder-andikeeps the cutting edge of the tool upto the work with more or less force, according to the thickness or inencss of the lines or marks required. It will benoticed that this operation is just the reverse from the ordinary process of lcutting'or ornamenting glass, in which the operator hdl'ds the work in hand and presses it up against the tool, which revclvesfon a spindle in fixed hearings, and while in this ordinary process the regularity of the vlines depends entirely upon the skill of the operator, in my process the work-is attached to a spindle or chuck, to which a regular continuous or intermittent motion can be imparted, whereby perfect What I claim as new, and desire to secure by Letters Patent, is-

1. Giving to the tool or cutter used in ornamenting articles Vof glass or other vitreous material a motioirtowards and from the work by handat the will of the operator, while the work is secured to a movable spindleV or carriage, in contradistinction to the ordinary process of cutting glass, in which the work is held in the hands of the operator and pressed against the cutter, which revolves in stationary vbearings, substantially in the mam ner and for the purpose set forth. l

' 2. The use of theirotating tool, in'combination with the spindle of an ordinary rose engine or engine turning machine, either with a circular o1 with anupa'nddown motion, substantially as and for thcipurpose described.

8. The adjustable head d, imd swivel head y,fin combination with the extension spindle I, carrying the tool H, all constructed and operating substantially as and for the purpose set forth.

4. The slotted plate J, carrying the hearing for the tool-spindle I, and arranged in combination' with the slotted table A, in the manner and i'or'the purposesubstantially as described.

5. The swinging shaft K, arranged in combination with the adjustable tool-spindle I, in the manner` and for the purpose substantially as set forth.
