IMPROVEMENT'IN MACHINERY FOR THE MANUFACTURE OF POTTERY.
Specification forming part of Letters Patent No. 192,823, dated July 10, 1877 application filed l March 16, 1877.
To all whom it may concern Be it known that I, RoBERT- GRAGEY, of East Liverpool, in the county of Columbiana and State of Ohio, have invented a new and useful Improvement in Machinery for the Manufacture of Pottery, of which the following is a specification, reference being had to the accompanying drawings.
The invention relates to an improved ma chine for the manufacture of oval ceramic ware or pottery.
lt consists inl the devices, hereinafter fully described, through which an elliptic oroval movement is given to a tool secured to a movable support, to which motion is imparted, and which is adjustable with relation to the mold or jigger-head.
The object of this invention is to supply a machine whereby oval ware can be formed independently of manual manipulation.
Figure l is a perspective view of a device embodying the elements of the invention. Fig. 2 is a central vertical section of the jig- Fig. 3 is a top view of the plate B". Fig. 4 is a ceutral vertical section of same. Fig. 5 is a like view ofthe trammel-plate, and Fig. 6 is a similar view of the slide K.
In the accompanying drawings, A represents a table or platform, suitably sustained by the legs and braces, as shown, a proper distance above the floor or other supportingsurface.
Upon one side of this platform, with its handle in convenient relation to the front of the machine, is provided the lever B, the rear end of which is pivoted in the upper end of the standard a, in front of which there is pivoted to the lever B the upper end of the drawbar b, which extends downward through an aperture in the platform, having its lower end pivoted to the front end of the arm D, the rear end of which is provided with a sleeve, d, and set-screw e, to secure it upon the shaft E, working in bearings in the dependent standards f, secured to the under side of the platform.
Opposite the arm-D there is similarly se cured to the shaft E another arm, F, the front end of which is pivoted to the lower end of a its attachments.
The front end ofthe lever gis provided with the fork I, which partially encompasses the collar 'i on the jigger-shaft K, the fork being connected, by the pivot-screws k on each side, with the collar, which pivots may he worked in, and operated as set-screws, fixing the position of the collar t', and operating both as piv. ots and set-screws, or may be worked out, and then operate as pivots only. Thus the position of the collar t' on'the shaft K is determined. rlhe elevation of the shaft is further regulated by the sliding collar L, having the set-screw l. The purpose of these :adjusting devices is to regulate the position of the jigger-head, and-thus determine the thickness of the ware being formed on the jigger-head.
The shaft K stands vertically, its lower end passing through an aperture in the .step m at the base of thedouble hanger M, through which the front partvof the lever q extends. The upper part of the shaft K, being angularly formed, passes a corresponding aperture in the front of the plate N, which is secured in the platform A, and forms the support of the hanger'M.v This gives the shaft a fixed vertical position. and still permits it to be elevated or depressed.
The elevation of the collar L is .determined by the shoulder n of the angular formation on the opposite parts of the shaft K, which, below the step m, is provided with a third collar, n', the elevation of which is determined by the step, and which further assists inregulating the elevation of the shaft.
From the above itgis plain that the. shaft cannot be unduly raised, and, further, that the pivoted connection of the lever g, hung on an oscillating fulcrum, avoids any dangerof 2 masas the shaft being deiiected While being elevated.
The plate N is secured in an aperture in the platform, to the front portion of the base ofthe standard carrying the forming mechauism; but it is obvious that many other expedients of strictly analogous construction may. be employed to eiect the purposeof the plate N and hanger M, which is simply to secure the shaft K in an upright position, and yet to allow its| vertical movement.
The'angular portion of the shaft K extends above the platform A, and there is secured at its upper extremity the jigger-head P., provided witlr an aperture to receive the mold p, which is retained in place on 'each side by lugs r, which lit into the notches t in the mold.
At aboutV the center of the platform A is securedtlie' base of the standard-A', the up per end of which: projects forward a suitable distance. Two arms, a', project upon one side ofxthehsta-ndard, the upper having a circular, the lower an angular, aperture, to receive and retain the 'belt-shifter B', which is constructed circularin its upper,- and angular in its lower, parts, and, midway between vthe armsza' isfurnished with the loop or bar b', over which the belt passes. The lower end' ofthe shifter has a projecting arm, d', on the extremity vof which is pivoted the crank-lug D', whichreceives at its re-entrant angle a pin or stud ,'e', on the lever B. This shifter is. so arranged that, when the lever B is depressed, which throws the jigger-headl into the operative position, the loop b' shall be direct-ly opposite the belt-wheel F' that gives motion to the forming mechanism; and also so that when the lever B is elevated, which throws the jigger-head out of operative position, the loop b shall be opposite the loose relief belt-wheel f', thus checking the motion ofthe-formingmechanism.
Thus the movement of the leverboth elevates the jigger to operative position and places the belt,.or depresses the jigger-head andzremovesthe belt.
Thefront of the standard A' projectsover thejigger-head',v and is furnished with the sleeve b'", which receives the upper end of hanger-E', all soarranged that the axial centers of the jigger-shaft K and the hanger E' are coincident. Upon the hanger E' and be.
low` the sleeve b'" is mounted the loose beltwheel j", andt below this on the hanger is mounted the belt-wheel F', tothe lower central parts of Which is rigidly secured the npper endr of the dependent sleeve-axle g', which rotates with the wheel F' on the hanger E'. Thev sleevel g is above the crown H', from which, on opposite sides, extend the angular armsh k', the arm h being furnishedy at its outer portions with the angular loop or slide K', movable uponthe arm h', and adjustable thereon bymeans of the set-screw L'. To the lower side of this slide is secured-the hollow stud- M',.which receives the end of the=hanger m', which. is reduced" to enter, the stud, andI is" furnished with the annular slot n", the sides of which are inclined to the base of the slot as an apex, this slot separating as a guide on the parts of the pin p' which cross the stud diagonally, and are conformed to suit the supercies 'ofthe slot. Thus tliehanger 'm' can have acertainl circular movement, and at the saine time a slight lateral play, but` all` other motion is prevented. The end of the hanger is provided with an aperture, r', which receives and supports the end of the'arm I', the
arm being of such size as to move readily in the aperture r', and having its inner end secured tothe plate B.
The arm 7c' is also provided with an adjustable angular slide, K', to which is connected the hanger t', which terminates in the curved bar n', having in it the extended slot N', whichreceives'the sleevew', secured soas-to rotate on the axle x', and projecting-beyond'.the-slot.
Theaxle a2' has a square shoulder, z', attheH end of the sleeve w', beyond which thea'xle is threaded, passing through a nu't, T', and-'fA thence in'to the cavity b"of the trammelplate B" through a block at its end', the inner end of the axle serving to clampthe bases of" the shuttles D".
The purpose of this construction may'bef thus stated: The slot N serves tovv permit the oscillation of the armv or axlex' as the plate' carrying the forming tool moves, andil the sleeve fw', while sustaining, allows theaxle'f to rotate, andpermits itsbeingscrewed to ward or from the shuttles. The' shoulder z" prevents the sleeve beingmoved toward' the plate, and Athus the axle may be operated' as ai clamp for the shuttles, while uut T' assistsiny securing the axle in its clampingv position.
To the lower end ofthe hanger E'fis se'- cured the trammel-plate A", which is traversed by two grooves or slots, a",crossin'g eachother at right anglesrat the center ofthe. plate. These grooves havetheir sidescorrespondingly inclined upward and inward. At'
their bases on each side are formed thev small recesses b".
Below the plate A" is placed thelplate or` platform B", sustained in proper position by the supportof the arm l', and the axle fr' encompassed by the sleeve w' on opposite-sides` of the plate. The platform B" is provided with the vrecessor cavity b", in-which is placed the angular bases 6"'of the shuttles` D", which are attached tothel upper parts of the bases:
e", so as to rotate thereon. The upper parts of the shuttlesf D" are wedge-shaped to". con'- form to the sides of the grooves a",l wherein they move freely, one shuttlein each groove.
A chock, E" ,is provided, which-may be'used.
to separate'the basesr c", thusfenlarging' the distance betweenl them, or thev distanceivbetween either or both from the edge-or centen of the plate B", thus-Y regulating-the orbitf'ofr the-tool.
Upon theiunder side-of the pIateB"l is pro#y vided the ridge-F", on` which is securedlthe'- base of the forming-tool H", which may be of any desired outline. The centers of the jigger-shaft and of the plates A" and B" are coincident.
Now, it is obvious that motion being imparted to the belt-wheel F', the arms h' and k' Will be rotated, causing the plate B'l to move, and the shuttles D" being in the grooves a" in the fixed trammel-plate A", and being capable of rotary movement on their bases applied with equally good results to forming the interior ofthe Ware, the mold being of' suitable shape to give the exterior form.
It will be remarked that in the above operation the jigger-head is stationary, While the trammel-plate and tool revolve, but it is obvious that an elliptical movement couldbe imparted to the jigger-head, and the tool remain stationary, though the present form of mechanism is be ieved to be -the more practicable.
What I claim asmy invention, and desire to secure by Letters Patent, is-
l. In a machine for forming pottery, a jigger-shaft operated by a pivoted lever hung on an oscilla-ting fulcrum, substantially as set forth.
2. In a pottery-machine, a lever hung on an `oscillating fulcrum, and pivotally connected with a jigger-shaft provided with movable collars for determining its position, as set forth.
v 3. The lever g, provided With the fork I, and hung on the oscillating fulcrum H, in combination With the collar i, substantially as and for the purpose specified.
4. In a pottery-machine, a jigger-shaft having a fixed vertical movement, and provided with collars and set-screws to secure its vertical adjustment, substantially as shown and described.
5.v A pottery-machine in which the movement of a lever simultaneously removes the jigger-.head from operative position, aud displaces the motor actuating `the forming mechanism, as set forth.
6. A pottery-machine, in which the device driving the forming mechanism is removed, and the jigger-head lowered out of operative position by the movement of a lever, as set forth.
7. vThe adjustable slide K', provided with a hanger having a pendulous movement. in combination with arm I', substantially as expressed.
8. The stud M', provided with the pinp', in combination With the hanger m' and arm I', as set forth.
