BASE FOR GLASSES.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed August 28, 1903. Serial No. 171,145.

To @il whom, it' may concern,.-

Be it known that I, HARRY SMITH, a citizen of theUnited States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Bases for Glasses, of which the following is a specification.

This invention relates to a base for glasses, and the device, which is simple in construction, capable of easy and inexpensive manufacture, can be employed with facility in many connections. One advantageous adaptation of the article is in conjunction with chemical graduate-glasses, in which use it is clearly illustrated in the accompanying drawings, forming a part of this specification. The structure of the parts represented in said drawings and the advantages following the same will be set forth at length in the following description, while the novelty will constitute the basis of the claim succeeding such description.

I do not limit myself to the exact disclosure made by the drawings and description, for certain changes as to several points may be made within the scope of the said cla-im.

Referring to said drawings, Figure lis what may be considered a rear elevation of a graduate-glass provided with a base including the invention. Fig. 2 is a side elevation of the same.

Fig. 4 is a detail view of a catch hereinafter more particularly described.

Like characters of reference indicate corresponding parts in each of the several figures of the drawings.

The bases or feet of graduate-glasses are easily broken, and when the base or foot of a glass is broken the latter becomes practically useless, as it cannot be stood in an upright position. By means of my invention I can advantageously employ glasses having brokenbases or feet or can attach the invention to whole glasses in order to preventthe breaking of their bases or feet. It will therefore be understood that one advantageous use of the invention is in connection with graduateglasses, one of the latter being represented in the accompanying drawings.

The graduate-glass is denoted in a general way by 5, and it -includes the usual cup portion and base, the neck joining' the cup portion and base having an annular groove.

The base, which is detachably connected with the glass, is preferably made from wire, as by Fig. 3 vis a horizontal sectional planview of the glass and base.

this material cheapness and lightness are secured,as well as acertain amount of resiliency. The base includes in its construction what I term a base portion 6, the same beingof annular divided or split form and being' adapted to rest upon a suitable support, as a prescription-counter. The base portion 6 is so con.- nected with the glass 5 as to be located below the base of said glass, so that when the base portion 6 rests upon a marble counter, for example, the glass base will be above such counter, so that the possibility of its becoming broken is exceedingly slight. From the ends of the divided annular portion the glassholding arms 7 projectinward, each arm consisting of a short vertical portion and an elongated horizontal portion, the vertical portions of the angular arms being directly united to the base portion 6. The horizontal portions of the glass-holding arms 7 are provided with substantially semicircular portions 8, which are adapted to lit into the annular groove near the bottom of the glass 5. Beyond the semicircular portions of the arms 7 are the forwardly-diverging projections 9, which serve as effective guides upon the application of the base to a graduate, it being' understood that the base constituting` the subject-matter of this invention is subordinate or auxiliary to the regular base of the glass, or if the regular base be broken as a substitute therefor.

The following is the operation in applying the base to a glass: Initially the outwardlyconverging projections 9 are introduced into the annular groove near the bottom of the glass, and either the glass or the supplemental base is moved to advance the glass between the horizontal portions of the arms 7. Duringl this motion said horizontal portions are swung outward until the free ends of the semicircular portions 8 cross what might be considered the transverse diameter of the glass. When such point is passed, the two arms automatically close upon the glass for a certain distance. I prefer not to rely upon the resiliency of the two arms 7 to hold the same positively connected with the glass, but for this purpose provide means separate from the auxiliary base, as will now appear. In the present instance this means consists of a catch denoted by 10 and which may be made from sheet metal. The catch l0 is sleeved onto the vertical portion of one of the arms 7, and it has a hook l1 at its free end to engage the vertical portion of the other arm. Of course when the supplemental base is being applied to a glass'the hook of the catch l() does not engage with the coacting vertical portion of the arm 7. Y When, however, the supplemental base is applied to the glass, the arms 7 are pressed toward each other, and the hook l1 is passed over the cooperating vertical portion, so as to hold the arms 7 securely in their closed condition. By this means the glass can have no relative motion with respect to the base nor can the two parts become accidentially separated. Vhen, however, it is desired to remove the supplemental base from the glass, the hook l1 is disengaged from the arm 7 that it is connected with, when the arms7 either by moving the glass or the supplemental base can be readily separated from the glass, the arms during such motion swinging outward. The base portion 6 of the device is generally made of larger Idiameter than the glass to which it is connected, so as to providegan ample support for the glass without possibility of the latter being easily tipped. The semicircular portions 8 of the arms 7 are concentric, or practically so, with the divided annular base portion 6, so that when the glass is connected with the supplemental base the two parts will be symmetrically disposed with respect to each other.

As hereinbet'ore indicated, the supplemental base may be effectively applied either to graduate-glasses with unbroken bases or those with broken bases. In the former case when the supplemental base is used the possibility ot' the glass-base being broken is remote, while in the latter case glasses may be employed which are generally considered useless.

Having thus described the invention, what I claim is In a device of the class described, formed of a single length of wire bent to the form, a divided annular base portion, the ends of the base portion provided with inwardly-extending arms disposed diametrically of the said base portion, each arm consisting of a hori- Zontal and a vertical portion, the horizontal portions of the arms extending approximately in parallelism for a portion of their length and having successively at. their inner ends semicircular glass embracing portions and outwardly-diverging portions, the arms at the junction of the said semicircular and outwardly-diverging portions approaching each other and being' separated by a space approximately the same as that between the straight horizontal portions of the arms, combined with a catch consisting of a sleeve supported for turning' movement by the vertical portion oi' one of said arms and having a hook for engaging the vertical portion of the other arm.

In testimony whereof l have hereunto set my hand in presence of two subscribing Witnesses.
