MOLD FOR MAKING GLASS PADS FORHORSE -COLLARS.
SPECIFICATION forming part of Letters Patent No. 404,766, dated June 4 1889.
Application filed November 16, 1888. Serial No. 291,000. (No model.)
To all whom it may concern.-
Be it known that I, DAVID BARKER, a citizen of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented a new and useful Improvement in Molds for Making Glass Pads for IIorse-Oollars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.
My invention relates to the construction and operation of molds for making gla s pads for horse-collars.
NVith these ends in view my invention consists in certain features of construction and combination of parts, as will be hereinafter described, and pointed out in the claims.
Figure 1 of the accompanying drawings is a view in perspective of the bottom portion. Fig. 2 is a similar view of the upper portion of the mold and fountain. Fig. 3 is a view in perspective of a glass pad as formed in said mold. Fig. 4 is a vertical transverse section showing all of the parts in position; Fig. 5, a side elevation of the plunger-operating camwheel with lower portion removed, and Fig.6
a view in perspective of plunger.
Similar letters of reference indicate corresponding parts in all of the figures of the drawings.
A represents the bottom portion of the mold, the exterior of which may be of any desirable form, the interior portion B, formed substantially as shown, having a convex portion on a line from Y to Y and concave from Z to Z to form the lower face or bottom a of the pad D, or, reversely, concave from Y to Y and convex from Z to Z, and about the edge of said form there is provided a fitting-surface b b.
On the ends of the bottom portion A there are provided drum s, as O, pivotally secured to the mold by a bolt d, passed through a centrally-located perforation in the heads h of the drums, about which the drums maybe rotated by the handles j, for the purpose hereinafter described.
In the rim of drum 0 there are provided diagonal slots is, the use of which will be hereinafter explained.
To form the apertures m in the pad, through which straps may be passed to secure the pad to the collar, pins, as n, are provided and loosely secured in perforations O. In the outer ends of said pins 91 a stud p is provided, the lower portion of which is projected into the slots 70. By rotating the drum 0 about its pivotal connection with the mold the studs p in the slot It will move the pins ninto and out of the mold.
The top portion of the mold is formed on the under side of the block D and the plunger E. WVith the plunger E in the aperture F the curve will be just the opposite of the lines described in forming that part of the mold formed in the bottom portion A-that is, the line from X to X being concave and the line from W to WV convex. WVhen the top portion D is placed on the bottom portion A, the fitting-surface will rest on the fitting-surface b of the bottom portion and the surface g on the surface Z), the central perforation forming a fountain, into which the molten glass is placed.
The plunger E maybe secured to the plunger or reciprocating portion of any of the wellknown forms of presses used for such purposes by bolts passed through the flange s.
The usual pins 25 are placed in and about the several parts of the mold, upon which wooden handles a may be placed, by which the mold may be handled when in use without burning the hands of the operator.
The operation is as follows: The plunger E having been secured to the press, as hereinbefore stated, the handles j are thrown down, rotating the drums 0 about their central pivot d, which will cause the slots to engage the studs 19 and force the pinsn into the mold R. The desired quantity of molten glass is then placed in the fountain F, the mold then placed under the plunger E, the press put into operation, the plunger forced down to the position shown in Fig. 1, having forced the glass into the mold 13, (shown in Fig. 1,) formed as hereinbefore stated, thus forming the pad, as shown by Fig. 3. The handles j are then raised up to draw the pins n out of the glass pad then formed in the mold, the plunger E withdrawn, the top portion D removed, and the finished pad removed.
Having thus fully described the nature and object of my invention, what I claim, and desire to secure by. Letters Patent, is-- 1. The combination, with a mold for form ing glass pads for horse-collars, as herein described, of the pins 92, to form the apertures m in the pad, said pins having studs secured therein, and d rum G, pivotally secured to the body portion of said mold, having slots 7a to engage the studs 19, whereby the pins 71 may be moved into and out of said mold, substantially as described, and for the purpose set forth.
2. The combination, with a mold for making glass pads for horse-collars, of pins having a sliding movement through the walls of said mold and through the said glass pad, and a rotatable drum having oblique guides which are engaged with said pins for the purpose of actuating the same, substantially as set forth.
In testimony whereof I have hereunto set my hand this 13th day of November, A. D. 1888.
DAVID BARKER.
