' This 1 invention. relates to watclnnens clocks for recording the movements of a Watchman in hi s rounds from one place to another at certain regular or prescribed in- 5 tervail's, orto record the activity or alertness of the Watch aboardship;

- The essential obj ects' of the invention are to provide an electrically controlled apparatus of the class specified wherein is em'- bodied a-novel and compact arrangement of instrumentalities for reliably recording, through circuit closing means operably associated? with a clock and a specially arrang'ed= rotatable dial disk attached thereto;

the time of inspection" or Watchful service of awatchman by actuation of the circuit clos-i Ineans located at different prearranged postsor stationsin' a manufacturing plant or factory, building compartments or aboard ship; to-indicate With certainty and accuracy the time that reports are made from independent stations included. in the installation; and further, to'preventall possihilityof an" irregular or incorrect record by providing a recording structure and arrangement of such nature as to defeat all attempts to change the mechanism" from a regular or normal condition of operation.

lVith theforegoing andother objects and a0 advantages invi'eW; the invention consists in: the preferred construction and" arrangement ofthe severalpartsa more fully describedm nd claimed? In: the drawing 5 "F'gure lflis a front elevation of a watchnian s' clock embodying the features of the invention, and showing the electrical. connections and wiring in diagram:

Figure 4: is a front elevation of the dial member which receives the record and which replaces the ordinary minute and Figures 5- and 6 are respectively a top planview and a side elevation of one; of the recording vibrating heads connected" to and operated by a vibrator.

In the accompanying drawing, a certain 5 arrangement of the several instrumentali ties is illustrated .for the purpose of compactness, and therewith is shown, in diagram, the source of electrical energy and the electrical connections and a specific grouping of the prime operating means or push buttons, but it Will be understood that the invention is not confined tothisp'articula-r arrangement of the several parts, but; may be varied in accordance with the appli- 5 cation of improved watcl'imans clock witl out in the least departing fro 1 the essential featuresqof the invention.

' As shown, t'he'improved' structure comprises a'base 5 and thereon is held a support 6 at one side and an upright 7 at the opposite side. On the support a clock 8 of ordinary form is held in fixed position and from the arbor 90f which the ordinary hour and minute" han'ds'are removed" and re placed by a special dial organizatiomdncluding an inner stationary metal disc 10, a rubher or yielding cushion disc 11 a record receiving dial' 1 2', a carbon'paper' disc 13' and an outer paper impression disc 14'. The discs are secured to a central sleeve ortubular att'achingmeans 15 Which is slipped over the arbor of the clockto' replace the ordinary 110111" and minute hands, the entire group" of discs being secured'for' unitary ros5 tation, and" to the disc 10, which may serve as the backing; are attached forwardly projecting studs or'keepers l6 arra'ngedat' equal distances on opposite sides of the center in diametrical alinement and inserted through 917 openings in all of the discsand in trans verse ali11en1ent,'as at 17. The discsl2; 13 and 14- are removably he'ldfl in connection With the metal disc 11 suitable clipsl's being'r'emovably applied" over" the e'dge'sfof all ofthe said discs. The'di'ail disc proper, indicated by'12; maybe replaced. at any time it may be found necessary by a" similar device; it beingunderstoo d" that" a" number of these'dial discs'will be furni'sl'iedwith each 16 pression a manner adapted to serve the pur embodied in the ordinary i f ter duced held, the said shelf brackets be' apparatus, and likewise when the outer imdisc 14 and carbon disc 13 becomes worn, they likewise may be replaced by similar devices. I

On the upright 7 a series of ledge or shelf brackets, 19, 20, 21 and 22 are secured and f sed at difierenfianglesyelatively to eac ='ot r in a vertical direction and having their supports arranged as ma be found necessary to serve the purposes 0 stability and firmnem in application. There are but four of these ledge or shelf brackets shown in the present instance, and they are disposed close to the clock 8, but it will beunderstood that the number of these ledge or shelf brackets may be increased as found desirable and arranged at other than those shown, or infany 0 an accurate recordingo ration of t e devices held-thereby. On eac ledge or shelf bracket is secured an, ordinary electro-magnetic vibrator 23, comprising the usual coils or magnets 24 and vibratory member 25 functioning as an armature relatively to the magnets The vibrating member or armature 25 of each electro-magnetic vibrator, has an arm 26 estendinghtherefrom and preferably forming a part t ereof, the said am corresponding to the bell'arm usually construction of v1- brators. In this instance, however, each arm 26 is shown bent at a point the length thereof .to enable the disposition in vertical alinement ofa series of vibrat' heads 27 in the form of metal blocks o sufiicient weight, and each carrying on its inner side a type member or face 28, all of these type membersor faces being'in vertical ahnement,'and' as shown, the said heads are all located above the horizontal center of the outer disc 14. r V H e The dial organization, as shown, may be enlarged as a unit, asdesired, and the principal member or element thereof isthe dial oi 12.,which receives the record, and

dial or di c is divided into ml a series of seamen divisions or sections 29 by radial in dimensions to V b v anordinary clock dial, saidfsegmental sections 29 regularly r diminishing 1n width by reason of the inw rd convergence of the radial lines 30. The sections 529 are divided by circular lines 31 concentrically around the entire record d 12 l e -sawi a means y enclosed blanks was at; the ceniandthereinare forme the'tw'o o' n' s f! a n ture hsm c o t ph 31' difvi ieachsection 29 mtospaces 3,1 posinonsj r yrgccept' on of the records pro- 2bly thegtypes of'the vibrating heads 1 There are four arcuat spaces 31 defined in each section 29 by the circular lines 31 to correspond to thenumber of heads 27 emen of said numera dial, e numerals 1, 2, 3, 4, etc., being to the left oiithanpper central numeral 12. The same arrangement will be efiected with either the ordinary or" Roman numerals, so that as the dial to the right or clockwise the earlier h'oius will "be successively brought into position for N for receiving the records ofthe hea a therein withaccuracy as to the time that said records are made by the actuation of theheads 27, and

T e P erated, by t e wat hman, consists of aseriq' 32 which may be arranged ifis s s a i ns-PP or partmentshor rooms,

' op rati g means,

only fourof these push buttons or circuit closers corresponding to .the numberof wit bratory heads 27. These push buttons are -of the ordinary construction of devices of tions.

this class and are connected up by Wiring, as at 33 and 34, with one side of a battery, the latter being connected, as shown, in a well known manner to effectually render the vibrators individually active when either one of the push buttons or circuit closers is actuated by a watchman. These push buttons 82 are also connected by wires 35, 86, 37 and 38 and are respectively secured to each of the vibrators and individually secured to a binding post 39 of each vibrator, as shown in diagram. The vibrators each also have a binding post 40 and connection is made thereto through a wire a1 and branch wires 42 to the other side of the battery so as to complete the circuit in accordance with well known Vibrator installa- It will be understood that the binding posts 39 and 40 will be respectively electrically connected to the windings of the coils of the electro-magnets 24. It will also be understood that each push button 32 will individually operate or render active the vibrator controlling the actuation of the head 27 with which it may be selectively and electrically associated, the push buttons being numbered similarly to the heads 27 which are arranged to be individually operated thereby.

From the foregoing, the operation of the improved device will be readily understood, and the vibrators and heads 27, together with the block and the dial organization embodying the several discs heretofore explained, may be enclosed, as desired, thus rendering them accessible to authorized persons only. Moreover, the recording dial organization and heads 27 with their operating means may be located at some predetermined point, as for instance, in an office enclosure, with the heads 27 operable at a considerable distance from the location of the present apparatus, which comprises in its organization stock elements readily procurable in the market, as for instance, the vibrators, push buttons, batteries and clock. The clock may be of any suitable type from which the ordinary dial can be removed and replaced by the present improved dial organization. The vibrating armatures 25, together with the arms 26 and the heads 27, may be formed integrally and of suflicient dimensions to insure strength and durability and certainty of operation, it being obvious that ifthe heads 27 have a certain amount of weight they will produce a superior impression and record through the medium of the disc 1% and the carbon paper disc 13 on the record receiving dial 12. g

It is also intended to adopt such minor changes in the details of construction and arrangement of the several parts as may be justified by the scope of the invent-ion as heretofore disclosed the claim.

\Vhat is claimed as new is In a watchmans clock, the combination of a base, a support carried thereby, an upright also carried by the base and adjacent to the support, a clock mounted upon the support, a recorder dial attached to and carried by the hour hand arbor of the clock, a plurality of angularly disposed shelves carried by the upright, a plurality of vibrator arms, one to each shelf supported by the shelves with their free ends radially aligned and in spaced relation adjacent the face of the dial, recording indicia carried by the free end of each arm, and a plurality of electromagnets carried by the shelves one to each shelf and each arm, and in influencing relation to the respective vibrating arms.

In testimony whereof I have hereunto set my hand.
