CLOCK-CASE.

SPECIFICATION forming part of Letters Patent No. 750,787, dated January 26, 1904.

Application filed November 29, 1901. Serial No. 83,982. N0 model.)

To all whom it may concern.-

Be it known that I, AARON D. BLODGETT, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Cases for Tower and Similar Clocks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to tower and similar out-of-door clocks.

It comprises a cylindrical metal case having means for the attachment thereto of a dialplate, a transparent plate, the clock-movement, and an illuminating apparatus, and also means for rendering it weatherproof and for securing it to a tower or other support.

In the drawings, Figure 1 is a view in elevation of thevclock. Fig. 2 is a view in horizontal section, also showing a portion of the tower or support for it. Fig. 3 is a detail view, principally in section, enlarged, to further illustrate its construction. Fig. 4 is a detail view, enlarged, principally in section, showing a modified form of the invention. Fig. 5shows a detail in construction, to which reference is hereinafter made.

Referring to the drawings, A is a cylinder or shell of metal of any desired size. at its outer edge an integral outward-extending flange a of considerable depth, which is adapted to cover the joint between the case and the wall 6 of the aperture B of atower or support Z1, and an inward-extending integral flange a, against the inner surface of which the protecting-plate C, of glass or other transparent medium, is held by holding knees or brackets 0 within the case and attached to it by screws or in any other desired way. Pack- It has and I prefer that the plate be enough smaller to permit of the placing between its edge and the case of a ring a of rubber, wood, or similar resilient material which has the property of compression and expansion. The case also contains the dial-plate D, which may be trans parent or not, as desired, and which is held in the cavity of the case by the knees or brackets c and by the knees or brackets (I, which are screwed, bolted, or otherwise attached to the inner face of the case. Packings of rubber, felt, or other material may be inserted bet-ween the faces of the plate and the brackets, and the plate maybe made suffieiently small to permit of the insertion between its edge and the wall of the case of the resilient ring of packing (Z.

The plate D may support the movement E, which may be attached thereto by bolts or screws 6. The plate has a central hole e, through which the hand-operating arbors or sleeves extend. This disposes of the movement upon the inner side of the plate D and the hands 6 6 upon the outer side of the plate in the cavity or space between it and the outer plate C. I prefer that the movement E be what is known as a secondary movement, electrically operated bya clock placed at any distance and having any desired relation to the movement.

I prefer that the knees or brackets c be shaped to provide supports for the inner as well as for the outer plate and so that their placing and attachment to the case and the securing of the outer plate C in position shall at the same time act to provide the supports and place of location of the dial-plate D.

To illuminate the clock, I prefer to employ one or more electric incandescent lights F. One such light is shown in Fig. 2. It is carried by an insulating-holder f, which slightly exceeds the diameter of the chamber and which is removably held in a hole f in the case of sufiicient size to receive it. There is thus provided an opening in the case of sufficient degree to permit the lamp to be entered therein and removed therefrom.

The inner edge of the case may have an outward-extending flange a, provided with an annularshoulder a and this flange is adapted to receive and hold acovering-plate a which is united at its edge by screws to the flange and which is held from lateral movement by the shoulder. A packing may be interposed between the plate and the flange.

Where the clock is to be fastened upon a tower or support rather than in it, then the flange a is transposed from the outer edge of the case to the inner edge, as represented in Fig. a, then forming an extension of the flange a and a base which rests against the face of the tower or support and through which bolts or other means for fastening the clock to the support extend.

It will be seen that the construction provides means whereby the case may be built into the tower or support as it is being constructed or may be readily located in an aperture previously formed for its reception without requiring nice adjustment of one or construction of the other, as the flange a is of sufficient width to not only lap upon the face of the tower or support and conceal and protect the joint between the case and the wall of the aperture, but is also of suflicient extent to compensate for any inequalities of workmanship in making the aperture and to render unnecessary a close fit. After the case has been placed in the aperture with the outer flange against the face of the tower or support the space remaining between the case and the wall of the aperturemay be filled with cement or other supporting-filling.

It will be noticed that the case is so constructed that all the plates and parts are accessible from its back side and also so that the plates C and D and the works must be placed in position from the open back, the outer flange a precluding the placing of the plates and Works from the front of the case. This makes it possible to reach all the plates and the works and to remove them from the inside of the tower or support after the case has been permanently located therein.

Instead of employing knees or brackets for sustaining the protecting and dial plates there may be used a ring of suitable yielding material and of the desired width and size between the protecting or guard plate and the dial and also upon the inner side of the dial, which rings are attached to the case. They may be made of leather, felt, or wood, with or withouta surfacing of polished sheet metal or other material.

When the wall of the tower is too thick to permit of placing the electric lights in the side of the metal case, they may be placed in holes of the case the flange a may be omitted from r it and the ring held in position by clamps dial-plate and need not be an electric movement. Any ordinary clock-movement may be employed and it may be mounted in the case in any desired way.

Where the clock is not illuminated, a dialplate of non-transparent material, like wood or metal, may be employed.

In Fig. 5 T have shown a construction in which the back plate is provided with a shoulder instead of the flange a and in which the plate is fastened to the case, the shoulder extending into or fitting the cavity of the case.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
