ELECTRIC ALARM-CLOCK.

SPECIFICATION forming part of Letters Patent No. 405,206, dated June 11, 1889.

Application tiled March 18,1889. Serial No. 303,693. (No model.)

To all whom it may concern.-

Beit known that I, BENJAMIN DUBINSKI,

of St. Louis, Missouri, have made a new and useful Improvement in Electric Alarm-Clocks,

of Vwhich the following is a full, clear, and

exact description.

The improvement consists, mainly, in the means for closing the electric circuit, substantially as hereinafter described and claimed,

To aided by the annexed drawings, making part of this specification, in which Figure l is a face view of a twenty-foun hour clock having the improvement, a portion of the dial being broken away to exhibit the I5 interior construction; Fig. 2, a section on the line II II of Fig. l; Fig. 3, a detail, being a section of that part of the clock-frame having the binding-screws; Fig. 4, a view in perspective of the spring used to secure the pins, 2o and Fig. 5 a face View of a twelve-hour clock having the improvement.

The same letters of reference denote the same parts.

A,Figs. 1,2, and 5, respectively, represents an .2 5 ordinary clock modified or supplemented by the improvement in question. Its dial appears at cc,its minute-hand at a', its hour-hand at a2,

its Works at as; and B represents a frame, which serves to support an d inclose the parts named,

3o substantially as shown, and also to support a series of pins C. The series extends around the clock, and the pins are arranged radially with reference to the shaft a, which carries the hands a a2, and their positions are re- 3 5 spectively opposite or in line with the divisions d of a graduation I), which encircles the dial a, and whose divisions are numbered or marked to correspond with numbers or marks c of the ordinary graduation E of the clock,

4o substantially as shown-that is, the arrangement shown in Fig. l is a twenty-four-hour one, and each hour-division is subdivided into four divisions, and there is a pin O for each subdivision. In Fig. 5 the arrangement is a twelve-hour one, and each hour-division is subdivided into four divisions, and there is a pin C for each subdivision; but any style of graduation and any desired number of pins may be used.

The pins C can be adjusted longitudinally in the frame B. Each pin independently of lettered O, Fig. 1*-they are in position to be 6o v touched by the arm G, Figs. l, 2, and 5, or other part attached to and carried around with the shaft at, and when a contact is thus estab lished the electric circuit is closed and the alarm F is sounded.

H I represent the usual wires for conducting the electric current. The wire IfI, by means of the binding-screw 72, Figs. 1 and 3, is connected with the frame B, which, as well as the pinsand their bearings, is of a suitable 7o material for conducting the current.

The wire I is supported by the binding screw t', Figs. 1 and 3, but the construction is such as to cause the current to pass through the binding-screw to the wire I', Figs. l and 3, 7 5 which lead to the alarm. The wire II', Figs.

l and 5, connects the alarm with the clockworks, which are also of suitable material to conduct the current to the arm G.

The alarm F is usually any form of the or- 8o dinary electric bell.

The operation is as follows: Suppose it is desired to sound the alarm at eighteen oclock fifteen minutes. The pin C', Fig. l, is pushed inward in the bearings until its inner end comes into the path traveled by the arm G, and as that arm is adjusted to keep with the hour-hand it is caused to form a contact with the pin at the time named, and as long as the contact continues the alarm sounds. The arm 9o G may be constructed in any suitable manner to effect and to maintain the current for a suitable length of time. As shown, its end g is in the form of a spring, which, as the arm G moves around, rubs against the pin and yields sufficiently for the arm to be carried past the pin, after which the alarm ceases to sound. The pins, it will be seen, are arranged to be adjusted in a plane parallel with the clock-face, whichI consider the most desirable roc method. The pins are held in either of the described positions by means of the spring J, Figs. 2 and -nainely, a strip of spring material notched at its ends j j to bear upon the pins, and between its ends bent upward to bear against the part Z) of the frame B. By this ineans the pins can be readily adjusted and sufficiently secured in either of their positions.

The divisions of the two graduations are preferably respectively opposite each other, as is shown in Figs, l and 5.

claiinl. The combination of the clock and the encircling series of pins, said clock havin g au arni rotating with its hour-hand shaft, and said pins being adjustable into and out of the path of said rotating arm, as and for the purpose described. A

2. The combination of the clock, the arin rotating with its hour-hand, the frame, and the series of adjustable pins, said series be ing in a piane parallel with the clock-face, substantially as and for the purpose described.

3. The combination of the clock, the arm rotating with its hour-hand, the frame, the

series of adjustable pins, the Wires, and the alarm, substantially as and for the purpose described.

l. The combination of the frame, the pin C, the pin-bearings, and the spring, said spring bearing upon said pin and also against said traine, substantially as described, and for the purpose set forth.

5. The combination of the clock having its graduation with the frame having its graduation, and the series of pins, substantially as and for the purpose described.

G. The eonibination of the clock having its graduation, the encircling iframe having its graduation, the series of adjustable pins, the arm moving with the shaft al, and the electrie alarni, substantially as described.

Witness iny hand this 16th day of March, 1889.
