SHOW-CASE.

SPECIFICATION formingpart of Letters Patent No. 224,562, dated February 17, 1880. Application filed June 23, 1879.

To all whom it may concern:

Be it known that I, THOMAS VAUGHAN, of Boston, in the county of Suifolk and State of Massachusetts, have invented a new and useful Improvement in Show-Gases, of which the following is a specification.

This improvement relates to arrangements or devices intended to facilitate the sliding and holding of the sliding doors at the rear of the show-case.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a perspective View of the rear portion of a show-case embodying my improvement, parts being represented as broken out, the better to illustrate the invention. Fig. 2 is a section upon line as t Fig. 1. Fig. 3 is i an enlarged section, showing the position and construction of the spring.

a and a are, respectively, the top and bot-' tom rear rails of a show-case. ,The sliding door b slides between said rails, being connected with the upper rail by means of the tongue and groove 0 61. At each end of the lower edge ofthe door is placed a spring, 6, projecting at 0 up into the door, and forming a U shape at c, and extending down into the groove f in the lower rail or base, a.

It will'be noticed that the outer ends of the springs e c extend slightly beyond the extreme ends of the doors 0, for the purpose mentioned below.

Within the groove, not far from the post, is

placed a knob, g. When the-door is closed the knob g, bearing against the part c of the, spring, prevents the door from sliding back. Nevertheless, in case it is desired to open the door, an ordinary amount of force applied thereto will cause the door to slide back, the spring c rising and slipping over the knob.

The door isgently and lightly held in a closed position, so thatalittle force is required The door I) is similarly arranged, constructed, and removed, except that it is, in being removed, first taken into the case and then drawn out.

The doors are separated by a centrally-situated thin metallic stationary post, Ir. This post or standard is important, as it not only supports the top rail and prevents the doors from binding, but it also separates the doors, which slide by it, by preventing them from rubbing or chafing against each other.

I am aware that I have described a rotary or pivoted standard in a previous patient; but this present standard is stationary, thin, and intermediate, allowing the doors to freely slide by it, and thus accomplishing the desired result in an economical and perfectly efficacious manner.

Rests h, or other suitable devices, may be used for holding up the springs. This improvement entirely obviates the necessity for the pivoted spring-standardshown in my Letters Patent granted March 27 1877, numbered Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a show-case, the combination of the sliding door or doors I) b, provided with one or more springs, c c e", of the shape shown, and arranged to project slightly beyond the outer ends ofsaid doors, and one or more knobs, g, set in a groove in the show-case rail, all arranged as described, and for the purposes set forth.

2. In a show-case, the combination, with the sliding doors I) b and the upper and lower rear rails, a a, of the vertical stationary intermediate standard; It, such standard ,bein g made thin and hidden from sightbetween the, two

doors, arranged to allowreach door to slide by it, and adapted to prevent the doorsfroln chafing against each other, substantially as set forth.
