IMPROVEMENT 'IN ILLUMINATED CLOCKS.

Specification forming part of Letters Patent No. 197,520, dated November 27, i877; application filed August 24, 1 7.

To all whom t may concern:

Be it known that I, ROBERT LEUGHSEN- RING, of New Bedford, in the county of Bristol and State of Massachusetts, have invented a 'new and useful Improvement in Illuminated vtion ofthe same; Fig. 4, an enlarged sectional detail view ofthe connections between the clockmotion. and the dial, Fig. 5, an enlarged detail view of an improved device for regulating the clock-motion; and Fig. G, aview of its adjustin g hand-screw.

The object of my invention is to furnish an illuminated clock for the sick-room which is illuminated by a lamp placed within the casev of the clock, so that its light will not irrita-te the patient, and in which the heat of its flame is also utilized for keeping warm tea, milk, or other requisites for the patients diet.

The nature of my invention consists in certain constructions, combinations, and arrangements of parts, hereinafter fully described and specifically claimed, whereby an illiuninated clock is produced which shows the time at night very plainly without emitting a disagreeable amount of light into the sick-room, which serves as a heating apparatus, and which may be conveniently carried from one place to another without disarranging the parts within.

In the drawings, A represents the foot or lower part of a clock-frame, which incloses a clock-motion with spring and balance-wheel escapement. The said frame A is, by preference, nia-de of metal, cast in one piece and without bottom, so that the said clock-motion is introduced from below, fastened upon a movable bottom, a, which is fastened within and to the frame A.

The dial-frame B (in ordinary clocks the clock-frame proper) is properly fastened upon the frame A, and has two bottom fianges, Z), between which the foot c of a lamp, O, is secured, either by simple fit, as seen in the drawings, or in any other suitable manner. The

back of the frame B is open; but it maybe provided with a door having' perforations to admit fresh air to the flame of the lamp. The front of the frame B has a round opening, b1, for the exhibition of the dial.

The dial-plate D is placed inside the frame B, and secured to it by bolts d or other suitable means, and it has the hours and. minutes marked upon its front and within the scope of the opening b1. The center of the said dialplate D is perforated, and provided with ametal bearing, which consists of a central tube, E, with a head, e, at one end, and a nut, c', at the other end, whereby it is fastened to the dialplate, as shown in Fig. 4.

A tube, F, with a bevel-wheel, f, at its one end, inside the frame B, and with an hourhand, f', at its other end, in front of the dial D, is inserted into the tube E, which serves as its bearing. A shaft, G, with a beveLwheel, g, at its one end, inside the frame B, and with a minute-hand, g', at its other end, in front of the dial D, isinserted into the tube F. The bevel-wheel g is driven by another bevel-wheel, 71 on an upright shaft, H, and the bevel-wheel f is driven by another bevel-wheel, 1'., on a tube, I, into which the shaft II is inserted. The shaft H is at its lower end provided with a socket, h1, which receives the square head j of the minute-shaft J of the cloclmnotion, and thus transmits the motion of the shaft J to the minute-hand of the clock.

The tube I is at its lower end provided with a wheel, i', which gears into a pinion, k, on a stud, K, of the clock-frame. The pinion k is coupled with a wheel, 7d, which gears into a pinion, h2, fastened to the shaft J. The shaft H is provided with a square head, h3, at its top end, whereby the adjustment of the dial* hands is effected, the minute-wheel J being so fitted on the shaft J as to allow it to be turned independently by the person operating it.

The'wheels fi and L and the pinionsz' and 7s alter theminute-motion of the shaft J into hour-motion of the tube I. v

The adjustment of the escape-spring L is effected by a guide-lever, l, as usual; but as the said guide-lever l is not accessible, I provide it with a pivot, Z', upon which a nut, M, is

mounted, through which a hand-screw, N, is passed. The hand-screw. N has a knob or milled head, n,`outside the clock-frame,for operation by hand, and an annular groove, n', which, in connection with a retaining-pin, n2, in the frame A, serves to keep the'said handscrew from moving longitudinally. The lower frame A has an opening, al, at the back, through which the clock-motion may be inspected, and an opening, a?, in front through which the lever L and handascrew may be watched while the clock is being adjusted. The top of the frame B is partly open to emit the heat of the lamp, and adapted to have a rack or open heating-support, O, tted upon it by inserting its legs 0 in suitable slots or perforations. Upon the said rack the nurse may place a vessel containingsuch liquids or substances as ought to be kept warm and ready for immediate use.

The frame B is also provided with a lug, b2, through which the tube I is passed, and whereby it is sustained in proper position.

To permit the clock to be wound up a hole, a3, is provided in the frame A, above the main arbor, for passing the key through, which key is made long enough to project above the clock-frame B, in order to facilitate the winding up.

The two frames A and B may be made of one piece without departing from my invention.

Having described my invention, I claim- 1. The clock-frame A B, constructed with a horizontal support, b b, in rear of its dial-plate and above its clock-motion., for the reception of a lamp, C, for giving illumination to the dialplate, and with a horizontal open ysupport in rear of and above the dial-plate for the reception of a rack, 0, upon which a vessel can be placed for heating food or other articles for use in the sick-room or nursery, substantially as described.

2. The shaftH, extended up through the top of the portion B of the case, and made a means of adjusting the clock-motion from the outside of the top of the frame, whereby the handling of the clock, when set against the wall or in any other position, is rendered un- 4. The hand-screw N, extended from the outv side of one side of the clock-case into the case, and passed through the nut M of the guidelever l of the escape-spring L, and prevented from moving longitudinally by. a pin, n2, in combination with a clock-case having the inspection-aperture a2 in its front and lower portion A, substantially as described. f

5. A clock constructed with means on the inside of its case for illuminating its dial at night, and with a support for a vessel or holder on the outside of its case, whereby food and medicines or other articles are warmed above its top with the heat of the flame which is employed for illuminating its dial-plate, substantially as described.

6. The combination of the minute-shaft J of a clock-motion, the wheels h2 7c k' i', the shaft H, tube I, shaft G, tube F, and bevel-wheels f g h c', whereby the motion of the clock is transmitted to the dial-hands f g', substantially as set forth.

Witness'my hand in the matter of my application for a patent for an illuminated clock.
