Patented June 22, 1937 UNITED STATES PATENT OFFICE LAMP MOUNTING FOR PHOTO-COPY MACHINES 1 Claim.
The present invention is directed to improvements in lamp mounting for photo-copy machines.
The primary object of the invention is to provide a device of this character so constructed that the lamps can be easily and quickly adjusted so that the rays therefrom may be directed properly on the work placed on the copy or engineers board.
Another object of the invention is to provide a device of this kind wherein the mounting for the lamp is so constructed that the lamp can be swung laterally, moved vertically and tilted with respect to the copy board for effective operation.
Another object of the invention is to provide a device of this type which is movable with the copy board and adjustable at various angles with respect thereto in a simple manner.
With these and other objects in view, this invention resides in the novel features of construction, formation, combination and arrangement of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which:
Figure 1 is a front view of the device.
Figure 2 is a side elevation.
Figure 3 is a sectional view on line 3--3 of Fig. 1.
Figure 4 is a detail view, partly in section of one of the frames.
Figure 5 is a sectional view on line 55 of Fig. 2.
Referring to the drawings, I designates the stand having mounted thereon the camera, 2, said stand having attached thereto guide rods 3 upon which are slidably guided the sleeves 4.
Formed integral with the sleeves 4 are brackets 5 adapted to support the copy or engineer's board 6. The board 6 is vertically adjustable through the medium of the screw shaft I which is threaded in the cross-bar 8. The construction thus far described is conventional.
Connected integrally with the sleeves 4 are webs 9 and to which are similarly secured the heads It] in which are journaled the lower ends of the lamp supporting rods II. Since the heads I0 are integral with the sleeves 4 it will be obvious that when the copy board 6 is elevated or lowered the heads ID, as well as the rods II will be similarly moved.
The usual Cooper-Hewitt lamps I 2 are mounted in the reflectors or hoods I3, as customary.
In order to support the lamps at various angles with respect to the board 6 brackets I4 are employed, said brackets consisting of frames I5, preferably of triangular form. The frames: have upon their rear ends vertically spaced and alined sleeves I6 and Il adapted to slidably engage the rods I I, the sleeves I6 having set screws I8 carried thereby for engagement with the rods I I in order that the frames can be held in various positions of adjustment on said rods.
The lower bars of the frames are formed with horizontally alined sleeves I9--I9 in which are fitted the ends of a relatively long sleeve 20, the purpose of which will later appear.
Slidable in the sleeves 20 are arms 2 I, the outer ends of which are formed with heads 22 having bores 23 therein and in which are engaged the shanks 24, said shanks being retained in place by the nuts 25. Set screws I9 secure the arms 20 in adjusted positions.
The shanks terminate at their lower ends in plates 26 adapted to intimately engage the plates 2'! carried by the castings 28 which are fastened to the hoods I3 in any approved manner. The plates 26 and 21 are normally held in intimate binding engagement by thumb screws 29 which pass freely through the plates 26, but are threaded into the plates 21. The plates thus arranged constitute clamps of such construction that upon manipulation of the thumb screws 29 the lamps may be tilted about the axes of the screws 29 in order that the rays therefrom can be projected on the copy board at varying angles.
Briefly the operation is as follows:
The board 6 is adjusted to the desired position and the work placed thereon, after which the hoods I3 and associated lamps may be adjusted relative to the board merely upon raising or lowering the frames I4 upon the rods II, and since the rods I I are rotatably mounted the lamps may be swung laterally and alined with the board upon adjusting the shanks 23 in the heads 22. Upon adjustment of the clamps constituted by the plates 26 and 21 the lamps may be tilted to the desired angle with respect to the board.
From the foregoing it will be seen that I have provided a lamp support for photo-copy machines constructed and arranged in such manner that the use of separate stands for the lamps are not necessary, and that the supports are compactly arranged.
What is claimed is:
In combination with the copy board of a photocopy machine, heads on the board and movable therewith, rods having their lower ends rotatably engaged in the heads, frames swingably and vertically adjustable on the rods, horizontally disposed arms adjustably connected with the frames and having heads on their outer ends, clamping devices each comprising a pair of plates, one plate of each pair having shanks thereon for rotatable adjustment in the heads of the arms, lamp hoods fixed to the other plates and clamping screws connecting the plates for holding same in adjusted positions.
JOHN J. JOHNSON.
