RECORDER.
`Application iled October 31, 1923.
To aZZ whom t may concern:
Be it known that we, VILLARD L. 'Eer and ROBERT l). DoDDs, citizens of -the United States, residing `at Troy, in the countykof Rensselaer and State of N ew York, have invented certain new and useful Improvements in Recorders, of which the following is a specification. j
This invention relates -to recorders and particularly to details of the construction of the marker carriage, and the feeding mechanism therefor.
The object of the invent-ion is to provide a structure in which the carriage Vmay be readily removed and replaced, in 'which the carriage may be quickly adjusted to time and in which the rate of feed of the carriage may readily be changed by interchanging the carriage feeding element or lead screw.
The ready removability of the carriage is secured by merely causing it to straddle the feed screw, the carriage. being so arranged t-hat it is guided conjointly by the lead screw and by the record drum. Convenient interchangeability of the feeding element or lead screw is secured by forming the screw on a removable sleeve which is clamped on a clock-driven arbor by lmeans of centering bushings and nuts. This construction alsopermits the sleeve tobe rotated relatively to the arbor and clamped in adjusted relation thereto. ln this way the position of the carriage may be adjusted so that the marking made by the pencil or stylus has the proper relation to the time rulings on the record sheet.
A preferred embodiment of the invention is illustrated in an accompanying drawing in which:
F ig. 1 is a side elevation of so much of a water stage recorder as is necessary to illustrate the invention;
F ig. 2 is an enlarged view of the carriage feeding member partly in elevation and partly in longitudinal axial section; and
Fig. 3 is an enlarged section on the line 3-3 of Fig. 1 showing how the marker carriage is guided and fed.
Many parts of the recorder, not essential to the understanding of the present invention, are only conventionally illustrated.
The recorder is supported on a base 6, which carries near its opposite ends two upstanding frame members 7 and 8. The recser'iai no. et/1,987. Y
ord drum v9, which is 'ofthe 'usual form, is journaled at one end in a-bearing 10,lformed inthe frame member 7, and at ythe 'other end in a bearing 11, carried by the 'frame member 8. The drum may bel driven yijn 'any suitable manner, but l show a mechanism `commonly used with water stage recorders. This consists of'a sprocket pulley 12, having the usual projecting pins to coact with the perforated bronze tape (not shown) customarily "used to convey the motion of the float to 'the sprocket- 12. The sprocket 12 has fixed to it a spur pinion i8 which drives a 'spur gear 15 through an idler 1.4i. Any desired drive for the ldrum "9 may be substituted so `far as the present invention is concerned.
A clock 16, `of any suitable form, is mounted on the frame member 7. lts hour shaft is indicated at 17 and Vdrives through a reduction trainJ consisting .of th-ege'arsl and 19, a stub shaft 20. This stub 'shaft 20 supports and centers one end fof an arbor 21, which fits over it, and which is connected to itby 'means lof a removable drift or pin 22.
The opposite Vend of the arbor' 21 is supported by a retractable journal member which 'enters a bearing formed in the end ofthe arbor 21, and which isgenerally indi- 'cated yby the numeral l23. The retractable journal 23 is threaded into 'the frame `member 8. By removing the journal 23 and the drift 22, it is possible to remove 'the arbor 21 from the recorder. The arbor 2l is threaded 2l, which engage flanged bushings 25.
vThese lit snugly on the arbor 21, and within the ends of a sleeve 26 clamped between them.
The sleeve 26 is formed with an endless groove 27, that is to say, with two reversely pitched helical grooves connected with each other at the opposite ends of the sleeve 26 and hence forming a single continuous groove adapted to feed the carriage back and forth at uniform rate.
Since the sleeve 26 may be rotated on the flanged bushings 25, it is possible to adjust the sleeve angularly relatively to the arbor 21 when the capstan nuts 241 are released slightly. As explained, this permits the desired adjustment of the carriage position to correspond with the time.
A marker carriage is indicated generally at 28 and consists of a relatively heavy cast- Cil ing having an elongated semi-cylindrical bearing surface 29, which straddles and rests upon the top of the sleeve 26.
A follower or key 30 is swiveled in the carriage 28 on a vertical axis, and engages the groove 27, accommodating itself to the reversal of pitch of the groove at the opposite ends of the sleeve. The marker, here shown as an ordinary lead pencil 31, is claimed in a vertical guide passage 82, formed in the carriage 28 by means of a clamp screw 33. rlhe carriage 28 is so dcsigned that its weight produces the necessary marking contact between the pencil 31 and the drum 9.
Since the aXis of the arbor 21 is parallel with the axis of the drum 9, the traversing movement of the carriage 28 moves the point f of the pencil 3l along an element of the cylindrical drum 9 and consequently the carriage 28 is guided by the sleeve 26 and the drum 9. The position of the carriage may be adjusted in the manner explained by an angular adjustment of the sleeve on the arbor. The carriage 28 may be readily removed from its operative position to permit inspection of the record, and may as readily be replaced.
It is occasionally desirable to change the rate of feed of the pencil by the clock, and this is effected by removing the arbor 2l in the manner already described, removing one of the nuts 24C .and substituting another sleeve 26, Whose cam groove 27 has the desired pitch, after which the parts are replaced in reverse order.
The construction described is simple and easy to manufacture, and permits standardization of parts with the resultant reduction in the cost of manufacture.
What is claimed is:
l. A marking carriage movement for recorders and the like7 comprising in combination a rotatable shaft; an arbor releasably connected at one end with said shaft; a retractable bearing for the other end of said arbor; a sleeve surrounding said arbor and provided with a spiral cam groove; releasable means for fixing said sleeve in place; and a marking carriage arranged to be driven by engagement with said cam groove.
2.V A marking carriage movement for recorders and the like, comprising in combination a shaft; an arbor releasably connected with one end of said shaft; a retractable bearing for the other end of said arbor; a sleeve surrounding said arbor and provided with a spiral cam groove; clamping means for adjustably fixing said sleeve in place on said arbor; and a marking carriage straddling said sleeve, engaging the cam groove therein 'and guided in part thereby.A
3. A marking carriage movement for recorders and the like, comprising in combination a shaft; an arbor releasably connected at one end with said shaft to rotate therewith; a retractable bearing for thel other end of said arbor; a sleeve surrounding said arbor and provided with an endless double-spiral cam groove; centering bushings surrounding said arbor and entering the ends of said sleeve; clamping means for urging said bushings into engagement with the ends of said sleeve; and a marking carriage in driving engagement with said cam groove.
4i. rlhe combination of an arbor; a sleeve surrounding said arbor and provided with a double-spiral cam; bushings surrounding said arbor and entering the ends of said sleeve; nuts threaded on said arbor and serving to clamp said sleeve in place on said bushings; and a marking carriage in driving engagement with said cam.
In testimony whereof we have signed our names to this specification.
