1 Claim.

This invention relates to lighting nating arrangements, and particularly to artools in the machine to become damaged because ofcond-itionsthat would be observed under sufficient light.

Having the foregoing in mind, the

object of the present invention is. to providean- A still further object is the provision of an par heavy presses, is generally almost com ptember 1'5, 1949;. Serial Divided and this application Serial No. 1%;481

illuminating arrangement for presses and the like so constructed that operating switches and the like can be incorporated therein, thus leading to a compact and efiicient arrangement.

In general the of this invention are obtubular light source in front of the working space of the machine and then movably positioning a reflector behind the light source so the reflector can be adjusted to direct the light to the proper location. A bracket supports and houses the illuminating means and reflector and can be used for supporting switches and the like which are utilized in controlling the operating of the machine.

This application is a division of my application Serial No. 115,901, filed September 15, 1949, and assigned to the same assignee as the instant application.

The foregoing objects and other objects and advantages of my invention will become more apparent upon reference to the following description taken in connection with the accompanying drawings, in which:

Figure 1 is: a front elevational view of a: by. i an illuminating arrange draulic press. having ment according; to this invention;

Figure 2'. is an: enlarged view looking. in: dillrectly at the front of the press where thefillumihating. meansis mounted Figure 3. is a illuminating: means Figure: 4 is transverse section. 4 4- of. Figure 3;

Figure 5 is a taken on: line perspective view showing the meanssforadjustingi the positionof the reflector associated. with the: illuminating means; and: Figure 5 is. a sectional view indicated byline 6-t on Figure 4' the: reflector can be: pivotally mounted relative to the tube.

Referring to the drawings. somewhat more in. detail; the

The head includes a motor aving a ram L6 to which is attached: platen: I8, which also supports a blankholder .29; space .of the press is indicated at 22 between blankholder '20 and bed It and is adapted: for

configuration, dash outliines at; 2 4'. According, to the: present invention, a rail. or

bracket 25,, better illustrated in Figures. 2 and? 3;.

is mounted between working space, as by screws gated tubular illuminating element as which may be a filament type lamp or a fluorescent or a neon tube, any of which are satisfactory for providing illumination. The tube 30, as will be seen the bracket.

In order to maintain the surface of the tube as clean as possible, the front end of the bracket prise plastic or glass, although a plastic material is usually to be preferred because of its resistance to breakage.

Positioned behind tube 3t! is a reflector element 3% which may have its end parts mounted about socket 3d, as indicated at it in Figure 6, so as to permit tilting of the reflector about the axis of the tube 39, thereby to direct the light from the tube toward the most advantageous position in the working space of the press.

A lever 42 which is attached to reflector 38 perspective View showing. the? showing. one. manner in which:

The working extends out of a slot in the top of bracket 26 and is engageable by a detent arrangement 44, which provides for a plurality of different operative positions of the lever and reflector. This detent mechanism may comprise spaced spring fingers or spring strips, as may be seen in Fig ure 5, and is a convenient and inexpensive manner of providing this feature of adjustability.

In general, the arrangement of the tube and reflector as described will provide for general illumination of the working Space with the reflector further providing a somewhat increased illumination over a selected area or zone within the working space, so that that part which must be most closely observed will be the best lighted.

The bracket 26 is made somewhat larger than is necessary for housing the tube and reflector and comprises a transverse channel arrangement 48 on the operators side within which push-button stations, as at 48, may be provided for controlling the operation of the press. This results in a convenient manner of mounting the push-button stations or switches and also positions them where they will be convenient for the operator to manipulate.

Other switches or push-button stations which are less frequently employed, such as those which determine that type of cycle the press will operate, may be mounted on the uprights H2 at the ends of the bracket, as at 50, as will be seen in Figure 2. Those switches, however, which are to be operated on every cycle of the press are preferably located on the bracket 28, as described.

From the foregoing, it will be seen that my invention provides for a relatively simple, inexpensive, but nevertheless highly efficient arrangement for providing for illumination of the working space of a machine tool. The arrangement with other types of machine tools and the like having a working space that requires illumination.

It will be understood that this invention is susceptible to modification in order to adapt it to different usages and conditions, and, accordingly,

I it is desired to comprehend such modifications is such that it provides not only general light- 0 ing, but localized lighting as well, where increased illumination is desirable.

The net result of utilizing my invention is to make the operation of ardous and more rapid with the assurance that a better product will result because it can be better observed during operation.

The invention has been particularly described in connection with a hydraulic press, but it will be understood that it is adapted for use in connection with other types of presses, as well as machine tools less baa-- within this invention as may fall within the scope of the appended claim.

I claim:

In a press an illuminating device oi the type described comprising: an elongated box-like hollow housing open along one side, a tubular lighting element in the housing, base members inside the ends oi the housing to receive and sup port the ends of said lighting element, an adjustable reflector in said housing on the side thereof opposite the opening in said housing, said reflector having its ends journalled on said base members so as to be adjustable about the axis of said lighting element, means to adjust said reflector comprising a transverse slot in the upper surface of said illuminated housing, a rodlike handle member secured to said reflector and extending through said slot, a detent arrangement including a plurality of notches along each side of said slot and engageable with said handie member, thereby selectively locking said handle member in a plurality of positions, and said housing being provided with a compartment extending lengthwise thereof inside the wall opposite the said opening, said compartment providing space to receive wiring and switches forming a part of the control system or" the press.
