Specification of Letters Patent,
Patented sept. s, 190s.
Application filed March 4, 190s. serai No. 419,142.
To all whom'it may concern:
Be it knownv that I, EDGAR ALAN Cri-STER, a citizen of theUnit-ed States, residing` at the citv of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have. in-
vented certain newand useful Improvements inMoldCarrying Turn-Tables, of which. the following is a specification.
My invention has relation to a mold carrying'turntable mounted upon rails at diilerent heights with respect to cach other and in which the table is eounterbalanced or poised and travels by suitable impelling means,
l without a center pivot or support for the table; and in such connection my invention relates to the Aconstruct ive arrangement of the tableifor the defined use, for particularly employment in the casting of soil, water and 'other pipe according'to the system' as set out or described and-claimed in United States Letters Patent No. S7(),17, granted to ine, under-'date of .November 12th, 1907.
"lne principal objects of my invention are Ifirst, to so arrange the supporting means of y the table that the same will occupy positions ron the surface of an imaginary cone, and thus 1forcing the table to assume the form of a` truncated cone; second to produce by said arrangement a tendency to maintain the tablt.` in one position with respect to its center, and to thus resist any Torce tending to move it from such position; and third to permit the weight of the table and molds 'carried by the same to assist in maintaining the table in a looted position aroundthe central axis of its support.
My invention consists of a turntable constructively arranged in substantially the manner hereinafter fully described and then claimed..
The nature and scope of 1n y present invention will be more fully understood from the i'rillmriuyl description taken in connection with the accompanying drawings forming part hereof, in which Figure l is a top or plan view of a mold en ri ying turntable, embodying the main ifearo es of my present invention; and Fig. 2 is :i central sectional View thereof', showing the de' Idl arrangement of the same.
ol'orring to the drawings 3,'is a circular conf-,reto or other material pit having a surrounding wall 4 and wnlk. Near'tlien'all 4, ol i c pi t are located tracks 7 and 8, the outer oth` S being preferably perched higher than ilif- Emiel' one 7, Within the pit 3.
9 is a turntable consisting of a circular skeleton frame 10, provided with a platform 11, and beneath which frame 10, is journaled at suitable distances apart single ilangcdor langed Wheels 12 and 13, engaging respectively, the tracks 7 and 8. Upon the platform 11, are mounted a 'series oftWo-part molds, at proper distances apart, toper'mit of lthe opening and closing of the. same. These molds 14. occupy a radial position' with respect to the center of thc table. The turntable is balanced or poised, without a r en t ral supA ort, by 4simply the Weight of the table and moljds carried thereby, and is adapted 7G to be manipulatedby irnpellingineans. 'The table travels in a circular course and whether. the.,copes are ,parted from the drags o f the molds of thel table or not', the poised position of the table isv such, as to pelnnit ,of ran easy and noisclcss movement thereof, wit-hout the p aid of' central pivotal supporting means for poising or balancingtlle sa1`ne. y The table being maintained in fixed operative'positio entirely bythe tracks arranged one above the other,l that is, at different elevations; and which may be either the inner track or the outer track of' the pair, and upon and over ,y 4which the table is adapted `to travel support'-l ing and carrying the series'of hinged molds 14, for the purposes described.` l
The construction of thetablc yi's'such that the platform and Wheels thereof are errang d in parallel lanes so that when the table is placed on t e rails occupying position at-dif: 90 ferent elevations the Weight forces it into the shape of a truncated cone toproduce thereby a tendency to always maintain such tablein one position with respect to the center of its support and moreover, to resist by this ar- 95 rangement any force which tends to move the table out ol such position. The Weight of the table and of the molds carried by the saine due to the truncated shape of the table assumed will aid in rimini-aiming the table in a lined position around the central axis of the .support thereof.
Although the dr'niings show'the table as assuming thc shape bf yan inverted truncated conc it will be understood iLthev outer rails were placed loxwer than the inner rails that the table in such instanccywould assume the shape of a rightV` laflmcategl cone With in prac tice lhosame results obtained asv a self centering table. The preferred` arrangement however, of the table, is as showin-because` adding strength thereto.
Having thus described the nature and ob- ]eets of my invention what I elaiin as new and desire to secure by Letters Patent 15:-
, 1. In combination, rails arranged atdi'fl'erent heights with respect to eachother and turntable adapted to travel over said rails and said table poised or balanced without a central pivotal support, substantially as and 'for the purposes described.
2. In combination, rails arranged at ditl'ermeans of poising or balancingr the table ontlie rails, and hinged molds airaiigtul, in series, on said table, substantially as and fortlie purposes described,
a turntable provided with a platform and l -Wlieels in parallel planes adapted to torce the table to assume in operative position the forni of a truueat ed eolie.
, ,In combination, rails arranged atl dill'erent elevations with respect to each other and a turntable constructively arranged tor operation in the forni of a truncated cone and 4. In combination, rails` arranged at dill'er-y `ent elevations with respectto each other and rails and said rails and wheels hol ing said table in a xed operative position with respeet to their central vertical axis.
elevations. a truncated cone turntable prorails, vthe construction and arrangement being suc-li that' the table is maintained in a fixed operative position with respect to the center of the support thereof.
7. In combination, rails, a turntable of' a truncated cone shape, 'wheels eonneeted with said table for supporting and permitting of the movement of the saine ove" said rails., lmolds 'carried by said table, said molds adapted to aidthe table in maintaining a central position with respect to said rails.
S. Iii combination, rails, a turntable of truncated eo'iie shape and provided Wit-h wlieels for su )porting and permitting ofi-he nioveineiit oil the saine over said rails and molds carried by 'said table, the truncated shape-of said table and molds adapted to re- .sist force tending toinove the saine out of tlie lixed-operative position with respeetto the 'center of said rails. i l
In witness whereof, I have hereunto set my hand in the presence of two subscribing Witnesses.
