Reissued June 1, 1909.

.To all whom it may concern:

Be it known that l, .l'lARHY Burns, a (if Zen of the United States, resnlin in Albany, in the county of Allin-11y and State of N f York, have invented a new and useful Time I Controlled, Coin-Operated Looking Device for 'lfype-ll'riter hilarliiiuzs, f which. the fol-Y lowing is a SPGCll'lOitlllOli, r nee being had i to the accompanying drawings, forming part thereof.

The object of my invention is to pro vide a means whereby a typewriting machine may be operated at u'edeternnined times only by unlocking and than looking its nieel'ianisrn by inserting or making use or a cash payment of l any certain predetermined sum of money inserted into the device with the purpose that i such tvpewriting machine may be placed in enabling anyone to ohtain the of the 111:1 chine for practice or for practical Writing purposes by depositing the predetermined sum of nnniey, say ten cents, in the attachment for the use of the sainfor say, onehalf hour, when the nmehine will lock and it will be impossible to obtain use of it until another ten cents is deposited when the looking device will unlock and remain so 1111- locked for the space of half an hour or the predetermined space of time so the end of which time the typewriting machine will lock last.

()no way in which i. arcoinolish this end is shown in the drawings hereto annexed and l which form a part of this specification.

Figure 1 shows the innit face of the clock on the same shaft 1 loosel' mechanism it is attached to the typewrih ing; machine in side elevation; Fig. an l view of two of the operating wheels attached l or hung on the minute hand shaft of the cloclnvorks; Fig. 3; n side elevation of one of the lovers; Fig. 4- a. face view of the coin coni duit with :1- portion of the lever seen in Fig 3; Fig. 5 a plan view of the trip device; Fig. a rear side elevation of a portion of lockin mechanism; Fig. 7 a side elevation of 1h locking linger; Fig. 8 an end elevation of clockwork; Fig. 9 a top plan view of a typewriting machine with portion hrolren away and my mechanism in its hex operatively attached to the typewriting machine and Fig. 10 the rear view of a type 'riting machine showing; some of the moving parts used in connection with my clock mechanism.

l l i 12 is detail. plan "to illustrate the manner in which the main lnindle or lever of the coin mechanism, during its return. td normal position, releases the coin-operated lever from the control of a. latch.

' shown is an ordinary The clockwork l eight day clock to be found on thegeneral market. It has two driving priifig actuated Wheels 2, 2, To the sh aft of +Jhe minute hand arbor 35 I firmly liXhhe toothed wheel and the wheel. 29

. gh its rim and the linger or indent 32 l 'i'irniily attach to wheel 29 and bring its free end to a knife edge. Between these two wheels I place a spring 33 which acts to keep the Wheels separate by pushing Wheel 29 as far toward the end'ol' shaft as it will go and w hen no pressure is exerted against the outer rim of wheel 2.) spring '33 prevents the knife edge of linger or indent 32 from engaging with the teeth on wheel 34 and the ()lOClCWOl'liS will run and revolve wheel 34. only, which it designed to do, while the typewriting machine is not in use, after it has come to at the end oi a peoiiied time, and in this inei'zl'ianisin rede terinined as thirty minutes or hell an hour. In order to have. the motions 0. heel 29 ac having two 3C, 30, l

On the slnil't 21 is lirmly hung the arm 23 (see Fig. 1) that has a de Jendin short lea 2-4: which lies net in front of Wheel 29 ready to slip into either of the slots 30 which may present themselves to it.

In order that the leg 24 shall leave the slots 30 absolutely and not reenter the clot again instantly, l pivot a plate 25 (see 1 6) by the pivot 28 to rear side of arm. 23, so it will swing on that pivot and provide it with a slanting and forward pro u g leg 25 and assist the protruding leg to assume a forward position as seen in Fig, 6 by the light spring 318,642. Application for reissue filed August 29, 1908. Serial mo -'iiw' out of the slot 30 and was kept from -rod 38 a rearward motion given to lever 4 will it free into a receptacle for it.

A retreating motion from and an approaching motion to Ward wheel 29 is given arm 23 and its attachment through a slight rotary movement given to shaft 21 through the arms 18, 18 and cross-bar 19 by the spring 21 on shaft 2 1 by l means of the coin conduit 5 and lover 7, the

coin conduit 5 being attached to the lever 4 as seen, and lever ,4 fastened to the revoluble cause a revolution of rod 38 against the spring of coiled. springs 37 and 39 and on, releasing lever 4 it will spring forward with considerable force and take its nornialposition without disturbing lever T. Lever 7 isseen in Fig. 3 and has notlrhes S and 9 and is lllifll) attached to rotating sleeve 4:0 which rotates on rod 38 freely and without in l'erfereneo with lever 4, being also spring actuated. it 10 (see Fig. 5) is a plate pivoted to the. lloor of bracket 10 and has a projection 11 1 1 1r pin against which spring 12 presses and swings the tongue with its notch 36 to the left and this is done so that when lever 7 is pushed back along the notched side of-the. tongue the notch will engage with the lever 7, and hold it fast untillcver 4 with the coin conduit and the coin fly back into their normal position and in doing which, lever 4 strikes against the corner projeelion ll of plate '10 and crowds notch 36 out of engagement with lever 7 when lever 7 files to its normal position striking, the coin and knocking While levers i and 7 were being operated as above. described, lever 7 also came into eontaet with l lever 13 and pushed it rearward giving a rotary motion to shaft 21 and' to shaft 2] against the resilience ol spring 2] which revolublo movement swung arm 23 away from wheel 29 and its leg 24 out of the-slot 30 together With the inc-lined and spring actuated leg); 25 which latter leg swung forward by pressure of sp' ing 27 and laid beyond the slot and 21;;zlil3fil. .he outer rim of the wheel and r-rould not allow leg 24 to again enter the slot until one half an hour had been expended and spring :u-tiiated leg 25 had nade. the circuit and had itself entered one oft-he slots 80 and tlzils acted as a guide to log 24. ="-.'hile the the lever 21 had the same. movement as arm in unison that is while 1e 24 on arm 23 was r-nierm lat-slotsl'oronehallhour,oruntiltho next slot presented itself to the leg in enter- 1 able position, the lever 21" with its engaging end 3] was drawn away from hookr (sew Fig; 9) and that hook being sprilngkuwtnatod re-.g lo sed itself f m pin (Z and the rod awas free i again to mane its neressary lHh-h' and forth motion or erulwise motion neceseau'y to allow 1 the mo-riage to make its steplike'rnfu .ion to l not stop the have the necessary spar-es between the printed Words on the paper, but when. the engaging end 21 of lever 21" is moved outward by leg 24 on arm 22-; entering; slot 80 in wheel 29 that slot is just deep enough to m; lie the movement of he; 2 and arm 23 enough to thrnsl enga on end 2] ol' lover fl 1" into eontaet with hoo and l'erre that hooi-z to r-nwith pm and prevent the 1*"; from workirm l.=|i. ll anot her win was inserlral and the. leve fife-rated.

At Figs. 1 and :1 the posi'ti i i of the re volving notched wheel 2? with rrl errnee to the released leg or latch 211, shows that about fifteen minutes have ela d sinee the last releasingoperation; the. wheel fl"! having; revolv d for about one had; the disianee between i s opposi .nr tehes 30, and a. hall hour being required hell u e mine-meat of thea'heel, after the laaxhes are itllitl l from one notch, to lr-rin the other notea irto ens en.ent with ilnlatrhr-w l he wheel 2%) is traveling in the direction shown by the arrow, so that in about iifteen minuti the left-hand notrh .30 will. reach tin; latrfshes 53 and El, so ii at they may spring into the notuh.

(s wounding the arbor is enabled to press the wheel if?) outwardly along said arbor lo a sullieient extent to release the knife-erle or pawl 32 from its eugaegement with the teeth on the constantly revolving \xher rested. At th-z same time that this pawl-r" leasing movement of wheel 2%) occurs, there is also a movenu-nt ol the arm 2 which carries the lat- chem 24 and 25; the moveuumt of this arm being in the omiosito direction from that oi" the wheel 2E), and being ell'eoti'd by a spring 2] on the vertical shaft 21.. it ill be understood that said spring 21 tends constantly to turn the shalt to the right, and by the. connections 18, 19, 20 to turn the vertieal'shaft 2'! also to the right, and thereby to press baekwardly the arm 23, which is li'fflll on said vertiral shaft 2 'lhe latches 2 t, 25 are thusconstantlytending to mm e to notebongagin i position. At the same time. the arm or lov r 2] on said shaft 21 swings the loth ing lover or dog 0 (on the rerlieafl shaft or turning-postf) into position to engage f. pin d, for the IHH'POHO of locking the typw write-r and hence preventing.the manipiilzL- tion thereof, to render it li1un-:a.hle until again released by the eoin-cohtr 1 ileil I\l((lHLHlt-.ln.

hence the latter continues to revolve and the clockte run, although the iQ'pLWiltlDg ma chine is locked against manipulation.

VVh'en, alter the parts have arrived at the normal condition just described, it is desired to unlock the type-writing machine, so that it may be manipulated, a coin is deposited in the coin chuteor conduit 5, and slides down the same, and comes to rest upon a notch or step 8 on the upper end of the upstanding lever 7, as seen clearly at Fig. 1.1. At this time, the coin blocks or covers the opening or cutaway 6 in the bottom of the chute 5 (the latter secured upon the. handle or lever at.) It will be understood that when said o 'iening is not blocked, the handle 1 may be swung to andv fro freely withoutany eiiect. upon the machine; but when said opening isblocked, as at Fi 1 and i1, movement ol the handle 4 to the right at Fig. 11 causes the upstanih ing arm 7 to swim: in the same direction, since the flanges of the chute 5 press the coin (seen in dotted line) against the upper end of the lever or arm 7; or in other words, the coin serves temporarily as an interponent between the driver 4, 5 and the driven member 7. The use of the coin therefore enables the operator to swing the arm 7, which in turn rocks the arm 13 on vertical shaft 21 in a direction to swing the arm 23 on the same shai't away from the wheel 29, so that the latches 24, 25 are withdrawi'i from the notch 30 in said wheel; this being done against the tension 01' the spring 21" on shaft 21, which latter is connected to shaft 21 in the manner already explained. At the same time, the arm 21 on said shaft 2i withdrawn, and the locking dog: (1', usually provided on the typewriter, releases the pin (1, and hence the typewritine machine may be operated f ily during the hall hour rcquirml i'or suliicient revolution of the wheel 29 to bring its other notch into register with the latches 24:, 25. During, the initial stroke ol the coin-actuated notched arm 7, just referred to, it moves to the right at Fig. 11 along; the edge of a sprin actuated catch .10, until it is caught in the notch 36 in said catch where it is held tom porarily. The operator then releases the handle 4, and the same is returned by springs 37' and 39 and engages a suitable corner or sluruhh/rgll on the latch ll), and turns said latch to release the coin-opcrated arm 7. During such return movement of handle 4, the coin 6 slips oil from the step 8 in the now motionless arm 7 and falls out of the chute 5 onto the step 9. lhcnee it may fall into any suitable receptacle. Upon the latch .10 being turned to release the lever 7, the latter is returned toward normal position by the spring, 21", acting through the train of mechanism already described, including arm 13. On its return after actuation, the handle 4 maybe arrested by an arm '12 (Fig. 8) thereon, contacting with any fixed part, as for instance a portion of the casing A in which the clock work is contained. hen the coin-operated lever 7 is released from the latch 10, the spring 21 is permitted to press the arm 23 and the latch 25 back against the edge or periphery of the notched wheel 29, whereby said wheel is pressed back against the tension of spring 33, to cause an engagement of the pawl 32 with the teeth of the wheel 34, so that the wheel 29 1nay be caused to rotate with the clock: work for the ensuing. half hour or other suitable period.

It will be understood that the latch 25 is spring-actuated, and, upon escaping .from either notch 30 in the wheel, springs to a position out of line with the latch. 2:4, and stands slantingly ahead thereof. This prevents the latch 25 (and consequently the latch 24) from mentoring the notch 30 from which the latches were just withdrawn; and of course latch 24 cannot again enter a slot until another half revolution of the notched wheel 29.

3 shows the winding posts of the clock.

Fig. 10 shows a rear elevation, and Fig. 9 a

plan (with my invention added) of a common typewriting machine, simply for the purpose of showing my device in operative connection with a typewriting nmchine. It is customary for the post. or vertical shalt l) to rock slightly at every keystroke ol the typewriter, said shaft carrying at its top the ordinary spacing dogs 0 and p, which work into and out or" the teeth of an escap'ement wheel a; one of said teeth being, shown at '11, and the remainder being indicated by a dot ted circle. This scapeinent wheel n is connected to the usual paper rarriagc, ol which in, indicates a part.

lhe vertical shai't I is usually rocked. by means of a her (i, the latter being reciprorated endwiseby the keys, and connected by an arm 1 to said shaft h. Thus the operation of any key causes swinging; action of the does 0 and 1) into and out of the teeth of the es capement wheel. n, whereby step-l )y-stcp Feed of the carriage is permit ted.

Upon thepart 'm of the rarriageis the usual catch Iii, which when the line of writing is about completed, engages an arm 0 and drives it to the right at Fig. 9. [ixod upon a vertical I'Oi k shaft f. Also fixed upon the latter is'a hook c, which is vibrated into the path of a pin (1 which is fixed upon said reciprocating bar it. This has the eli'ect of preventing reripror.ation of said bar a, and hence it becomes impossible to operate the keys, so that the typewriting machine is usually locked last at the end of oath line. The above described typewriter mechanism and operation are common nnd well known in the art. 7

My time-controlled device nuioizzzaiicully Said arm c is operates by means of the device 21, to operate the hook c of the t 'pewriter after the machine has been. in use a half an hour and regardless ol' the position of the carriage of the typcw riter. P

The catch 1* forms ipart oit'hc typewriting nuu'hine; and the part 31. L. i forms a movable device norn'mllv emraging the part c of the typcwriting machine, to hold it. in the path of the pin (1 to prevent the operation of the bar 1, and hence to prevent the operation of the typewriting machine means being pro- "ided to more the part 2'1, 21 to abnormal posit ion upon the deposit of a coin and operation ol'lever 4; and at t he end of a predctermined period. the time-cont'roiling mocha-re ism ooperates with. means to restore said movable device 2i", 2] to etl'ectivc position.

do not routine. myself in my inventirm to the type of t wwriting machine shown, but claim it broadly when used witlrany type-- writing machine, in object being to provide any typcwriting machine with an autoniatically operating, time-controlled locking; device so that by the prepayment ot a certain amount. oi money the typewriting machine will be unlocked and be operated for a pro determined space of time and at the end of the time be auttmiaticall locked fast what ever pm'tion. of the typewriting marl. e may be, used as the point. at which to it or whatever may be the mcchai'iisni adopted to operate the loflring device.
