ADJUSTABLE CHAPLET-HOLDER FOR SUPPORTING AND CENTERING CORES.

SPECIFICATION forming part of Letters Patent No. 515,311, dated February 20, 1894.

Application iiled August 30, 1893. Serial No. 484,364. (No model.)

To @ZZ whom it may concern.-

Be it known that I, FRANKLIN L. BADGER, a citizen of the United States, residing at Concord, in the county of Merrimac and State of New Hampshire, have invented certain new and useful Improvements in Adjustable Chaplet-Holders for Supporting and Centering Cores; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as will Ienable others skilled in the art to which it appcrtains to make and use the same.

The object of the present invention is to provide core-supports which are readily adj ustable to various sized cores and convenient for use as well.

The invention is in the line of that on which I obtained a United States patent, No. 457,021, dated August 4, 1891,-embodying improvements which I found necessary after subjecting saidpatented invention to practical use for years. The diiference between the devices patented by me as above and my present invention and the superiority of the latter over the former, will be fully set forth in the following specification and claims, and clearly illustrated in the drawings accompanying and forming a part of same, of which- Figure 1, is a cross section of a two Ypart flask containing both halves of a plain mold for a cylindrical body and a core, and showing my improved supporting devices in elevation as when sustaining the core in its proper position, Fig. 2, being a longitudinal section of the two part ask, its mold, and the core, having my supporting devices in elevation. Fig. 3, is a detached broken plan view .of a portion of my improved device used in the cope, and Fig. 4, is a plan View of the device used in the nowel.

Like letters refer to similar parts throughout the Various views.

A is the nowel, and B, the cope portions of a flask. b are the cross-bars in the cope.

C, represents the core, and C', the mold.

C', is the ordinary core print, which when a core is short, is the only support required.`

The construction I have found preferable after long experience for the supporting device designed for the nowel, consists of a bar substantially of the form shown at D, having its endsperforated vertically at an angle, as at d, and the rods d', mounted therein and secured and rendered adjustable by the set screws d2. The construction I now prefer for use in the cope consists of a yoke E, fitting either of the cross-bars b, and provided at one side with a set screw e2, for securely clamping it tosaid barb, andwith a perforation e, as seen best in Fig. 3, for the reception of the adjustable rod e. Each of the rods d,`and e', is perforated at one end as in Figs. 3-4, for the reception of headed studs X, as shown in Figs. 1 and 2, their heads be- Ying perfectly smooth and sufliciently large to Vavoid any liability of crushing into a core.

I will now note a few of the advantages of the present devices over those of my patent above mentioned: Of the support for use in the nowel, the rods d by being adjustable within the plate or bar D, will do dut-y for coresofa greater variety in diameter than will that of my patent above mentioned, and is also much stronger, as the only means of adjustment to cores of a smaller or larger diameter in that device was obtainedl by the use of various lengths of studs similar to those shown at X, and when made long they are quite likely to bend and thus be rendered inaccurate; then again my present construction is cheaper for the reason that one size of the plate or bar D,Will answer foragreater variety of cores than will the other device, and the advantage of my present over my former device for use in the cope is the ease with which all the rods e are .made to bear upon the same longitudinal point along the core;- with the yokes E, clamped eachgat a corresponding point upon the partitions or bars b, the rods e will all hang in alignment. The

holes or perforations d and e, are preferably formed at at that side through which the set screws respectively d2 e2, enter, for the purpose of readily centering a rod even though their diameters may vary.
