Nov. 9, 1943. H, D. COLM'AN RECORD MECHANISM Filed Aug. 2, 1941 2 Sheets-Sheet Nov. 9, 1943. H. D. COLMAN 2,334,145
RECORD MECHANISM Filed Aug. 2, 1941 2 Sheets-Sheet 2 INVENTOR Howar .D. Colman ATTORNEYS 44 and finally around sprockets 28' on a shaft 28 from whence it passes into the main section of the storage mechanism. The shafts 28 and 50 are stationarily mounted in closely spaced parallel relation and are connected by a gear train shown in dotted lines in Fig. 1 and comprising gears 29 and 30 on the shafts 28 and 50 respectively, and an idler pinion 3|. Thus the sprockets 28' and 50' rotate in unison and together constitute a single or inner drive means for advancing the chain at one side of the loop. The opposite side of the loop presents an outer straight run which is advanced by a second or outer drive means comprising a pair of sprockets 53 on a shaft 16 suitably mounted in the frame structure.
The two drive means thus associated with the chain at opposite sides of the loop are arranged to be actuated independently and the loop will remain stationary or shift bodily in one direction or the other according to the manner in which the two drive means are operated. Thus. if the sprockets 53 are driven in a direction to move the outer run 5| of the chain upwardly while the shafts 28 and 50 of the other drive means are stationary, the car 43 and the loop thereon will move upwardly. But, if said shafts rotate in the direction indicatedby the arrow in Fig. 1 and the sprockets 53 are stationary. equal lengths of the chain will be fed into and drawn out 01' the loop and the car will move downwardly. On the other hand, if the two drive means on opposite sides of the loop operate simultaneously to advance thechain at each side at the'same rate, the car and the loop formed thereon will remain stationary.
The means for actuating the two drive means at opposite sides of the loop form per se no part of thepresent invention. As disclosed in the aforesaid'application, Ser. No. 319,047, the shafts 28 and 50 areopera-tively associated with a suitable clutch controlled mechanism (not herein shown) adapted to feed chain into and withdraw itfrom the loop 6; and the shaft '16 carrying the sprockets -53 is actuated by another clutch controlled mechanism operablefto advance the outer run of the chain upwardly as an incident'to the recordation of signals upon the chain.
Before entering the loop 6, the chain passes over a suitable blanker (not shown) operat ve to position the pins 8 uniformly for pres ntat on to a signal responsive recording device I 54 of any suitable'or preferred character, as for exam e. that shown in sa d parent application. Said recording device is herein shown as l cat d somewhat below the sprockets 53 and opera tea to record signals upon the outer run of the cha n as it is advanced u wardly by said sbimfk ts. It will be seen that if the sprockets 28' and 50' remain stationary in this operation. he cha n will be withdrawn from the lower port on of the loop between the sprockets 58' and 53, and. a
gradually increasing length thereof will be introduced into theupper portion of the loop above said two pairs of sprockets. Conversely. if the sprockets 28' and 50 are actuated'while the sprockets 53 remain'stationary. the length of chain in the upper portion of the loop will decrease and that in the lower portion of the loop will increase. In either case, the car 43 moves endwise in one direction or the other and the chain is not only maintained taut at all times but is effectually supported and guided with respect to the signal responsive recording device I54.
In some instances where a large storage capacity is not required and it is merely desired to compensate for different rates of advance at two spaced control points the shiftable loop may constitute the entire storage medium. In such event a loop 6 entirely closed maybe employed as shown for example in Fig. 5. With the construction shown in Fig. lit is of course contemplated that the signals or other intelligence recorded upon the loop 6 will be utilized at another point in the apparatus in the control of a sensing device such as a signal transmitter, the storage or record medium being in the form of an endless band of substantial length, as disclosed in said parent application. When, however, a single closed loop constitutes the entire storage medium, the stored matter is recorded on the chain or band at one side of the loop as at I54 and is utilized for control purposes at the other side of the loop, as by means of a sensing device M3 responsive to the setting of the pins 8 as in said parent application. Thus the loop 6 provides two opposite runs of substantial length with which the recording and sensing devices are respectively associated. Between these devices a variable length of storage medium may be interposed by a shifting of the car to compensate for a differential rate of advance of the storage medium at opposite sides of the loop, the two drive means, as in the preceding instance, being capable ofadvancing the chain in the two opposite runs independently or at different rates. As shown, they comprise two pairsof sprockets 54 and 55 respectively mounted on shafts 58, 51. In other respects the construction is similar to that of Figs. 1 to 4. It will of course be understood thatbefore re-presentation to the recording device I54 the pins 8 will be reset by means of a blanker of any suitable or preferred charactor.
