9 Claims.

This invention relates to show cases, and is directed to a practical and novel means for connecting together the opposite upper corners of the ends of a show case at the front thereof, said show case having a glass top and glass front interposed respectively above and between the ends; and the show case may be provided with the usual sliding doors at the back for entrance thereinto. The vertical ends in practice are of wood, though of course, they might be of other material such as glass with. enclosing wood frames surrounding the glass. At the upper rear corners of the show case the ends are connected together by suitable rigid cross bars which fur- I nish part of the framework for the sliding doors.

But at the upper front corners of the ends where otherwise there would be a danger of outward warping or other undesired spreading of the ends of the show case away from the end edges of the glass top and front, my invention is adapted to be applied for holding the ends of the case in proper position and snugly against the end edges of the top glass and side edges of the front glass, both initially at the erection of the showcase and also if at any later time any further adjustment is needed.

A preferred construction embodying the invention is illustrated in the accompanying drawings, in which:

Fig. 1 is a perspective view of a show case viewed from above and in front, and to which my invention has been applied.

Fig. 2 is a fragmentary plan view of one end of the show case, the glass top being shown in dotted lines.

Fig. '9 is a similar view illustrating a further step of the assembly of the show case beyond that shown in Fig. 4.

Like reference characters refer to like parts in the different figures of the drawings.

The show case with which my invention is used has a base I, a vertical front 2 of glass, and two spaced apart vertical ends 3, the upper edge portions of which are rabbeted or cut away at the inner portions thereof to leave upwardly extending ribs 4, one at the outer side and upper edge of each of the show case ends and for their entire length. The top glass plate 5 is laid between said ribs 4, extends over the upper edge of the front glass plate 2, and rests at its rear edge portions upon a horizontal rail 6, at its rear edge coming against an upwardly extending rib or rail 1 conheated to or integral with the bar E, said rails connecting the rear upper corners of the ends 3. The doors 8 at the back of the show case may be of any well-known conventional structure and in practice usually are slidably mounted so as to overlap each other and thus may be moved bodily for access to the interior of the show case.

At the upper edge of the front glass plate 2 a fabric strip 9 usually of felt is cemented or otherwise permanently secured the full length of the glass. The vertical edge portions of the glass are preferably received in vertical grooves near the front edges of the ends 3 (Fig. 9) A fiat metal band or tape I0 is laid over the felt strip 9, being of substantially the same width as the felt, and is cemented thereto for the major portion of its length but at each end is free for a distance,-

as shown in Fig. 9. Over the metal band ID a second strip of felt H is placed and cemented or otherwise permanently secured to the band I each end to within a short distance of the front.

end. A rod I4 is mounted for rotation in each of the grooves IS, the rear end portion of the rod extending through a suitable opening in the rail 1, as shown. The rods are slotted at their rear ends as indicated in dotted lines in Fig. 2, for the reception of a screw driver.

In the upper edge of each end 3 at the front portion thereof a recess is mortised ahead of the front end of the rod I4, in which recess a mechanism is mounted, the two mechanisms having the two ends of the metal band I0 connected therewith, and each of said mechanisms having the front end of the adjacent rod I4 connected thereto, said front end of the rod I4 being reduced in diameter and screw-threaded at Ma.

Each of said mechanisms located in a mortised recess includes a flat metal base plate I5 (Fig. 4)

which is secured by screws to the end 3 upon which it is mounted. The rear end of the plate I5 is bent upwardly at right angles and returnbent downwardly as at I6; the two overlapping parts of the metal at I6 having an opening for the free passage of the threaded section Ma of a rod I At.- A triangular shaped lever H, which in effect is a bell crank lever, is pivotally mounted at one corner at I8 on and above each plate I5. The forward end of each of the pivoted levers I? is cut away at its upper side for a depth somewhat greater than the double thickness of metal at I2 of the band I0, and is equipped with an upwardly extending pin I9 so that the end portions I 2 of the metal band I [I may be hooked over the pins, it being understood that openings are made through the parts I2 for such purpose. As shown in Fig. 9, in the assembly of the parts, after the plates I 5 have been secured in place as in Fig. 4, the members I! are then pivotally mounted upon the plates and the band member I!) with the attached felts 9 and I I connected with the pins IS. A bar 26 has its front end reduced in width as at 2! to form a narrow tongue which is pivotally connected at 22 to the member I I, each of said members I! being slotted to receive the reduced tongue 2I. Each of the bars 28 has its rear end portion interiorly bored and threaded so that the threaded ends Ida of the rods Id may be screwed thereinto. Thus the plates I5 may have the hell crank members VI to which the bars 20 have been previously pivotally connected mounted thereon, and then the rods I l connected with the bars 28 and the metal band I8 connected at its ends to the pins I9.

The assembly of the case then proceeds by applying sheet metal members 23, which, as shown in Fig. 2, are of flat metal from which front hooks 24 extend, formed integral with the plate 23 and adapted to embrace the front edge of the upper glass plate 5 when laid over the top of the show case. At its rear end each plate is narrowed in width and bent downwardly and extended as an arm 25 which lies against the base plate 55 and is screw connected thereto as shown in Figs. 2 and 3. Each plate 23 is connected to the bell crank member I! beneath by a screw 26 passing downwardly through the plate into the body of the member I1 below.

Each of the rods I4, one mounted at the upper edge portion of each end of the show case, may be rotated by a screw driver connection thereto, in this manner swinging the pivoted lever member I! about the pivotal axis of the screw I8, so as to tend to move the pins I9 outwardly. As the metal band II is of a fixed length, the effect is to draw the front upper corners of the ends of the show case inwardly toward each other until the ribs 4 come snugly against the end edges of the top glass plate 5. If at any time after the initial installation there is any separation beas shown tween the end edges of the top glass plate and the ribs 4 of the ends of the show case, it is very quickly corrected by a simple screw driver operation of either one or both of the rods I4.

With such construction a very practical and simple tie between the upper front corner portions of the vertical ends of a show case is provided and one which can be adjusted and controlled in a simple and practical manner. At the same time the tie which is used is covered and out of sight, being covered by the upper felt -II so as not-to be visible from above, whereby the'show case presents the same appearance as in any case,'it being common to insert a felt strip between the upper edges of vertical plates of glass and the underside of top plates of glass in show cases of substantially all types. By reason of the-screw connection of the parts Ma with the bars 2E an d the bearing of the ends of the rods I 4 against the parts IS, with the tension in the metal band ii), there is provided a binding action between the threads of the parts Ma and the threadedsockets into which they are inserted, which is sufficient to hold the rods Hi from any tendency to unscrew and release the tie between the upper front corner portions of the opposite ends of the show case. The construction is readily manufactured, and easily installed when the show case is erected.

'The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
