'I'he invention relates to a display counter and sign, including a novel means of mounting the more particularly to that type of counter which coil, as will be set forth in the following deis provided with refrigerating coils. scription and claims.

A modi of being disconnected. cation of the joint 24 is shown in Fig. 4.

Other objectsand features of the invention The duid-tight joint is provided by forming 5:, have to do with details of construction and deilanges 21 on each of the joining or abutting pipe 55 ends. Nuts 28 are provided with a threaded end which engages an intermediate coupling piece 29. Packing washers 30 are placed between the nuts 28 and the ang 21. Other types of joints may, of course, be used, as long as they permit the movement of the coil.

It will be seen that if the coil I6 is in its normal position, as shown in lig. 2, access may be had to the collecting pan or drip pan I5 only through the various conduits making up the coil I6. I have shown and, with the flexible connections between the coil and the supply and return pipes 22 and 23, it is possible to lift the coil I6 to the position shown in Fig. 3 where it is substantially parallel with the sloping window. In this position the coil may be fastened by a hook 3| and it will be seen that the collecting pan I5 may now be easily cleaned or painted as desired.

While I have shown only a collecting pan l5.

between the upper and lower storage chambers of the display case, it is quite possible that a permanent partition might be located directly beneath the collecting pan l5 in case the lower portion oi' the display counter is not to be cooled.

In Fig. 5, I have shown a slightly modified form of coil in which the inlet and outlet ends of the coil also furnish the pivotal support for the front edge. In this modification the supply pipe 22 is located in one end of the counter and the return pipe 23 is located at the other end. Pivoted joints 24 are located at the ends of these supply pipes on a horizontal axis. 'I'he inlet end o1' the coil I6 is brought down along the end of the coil as at 32 and is turned so that it enters the pivoted joint 24 on a horizontal axis extending longitudinally of the case. This axis is in alignment with the axis of the pivotal joint 24 at the other end of the'case so that the front edge of the coil is supported bythe pipes 22 and 23 and the entire frame formed by the coil may be pivoted on the joints 24. With this modification `it is not necessary to provide the flexible hoses 25 and 26 as in Fig. 1.

In case a cooling coil is also located in the top oi the case it is within the contemplation of the present invention to have the top coil, as well as the lower coil, connected to the same supply and return pipes as long as the connections of the lower coil are such that it may be moved as described. It will be seen that if an expansion valve is used in connection with a thermal bulb mounted on the coil, a flexible connection may be provided therefor.

What Iblaim is:
