employed as a power roller to effect the operation of the measuring lnstrumentality, and wherein means are provided for separating the rollers to facilitate the introduction or removal ofthe fabric and for slitting the fabric at the completion of the measuring operation to furnish an indication of the line along which the measured length is to be cut or torn from the rest of the goods.

Certain conditions are encountered in practical use which makes it desirable that the two operations of separating the rollers and slitting the fabric should be independent, not withstanding that it has been proi posed in the prior art toperform the two operations in correlation and by the operation of a common element.

The principal object of the present invention, therefore, is a measuring machine having a conveniently accessible arrange ment of devices for the operation of the means for separating the rollers and slitting the fabric wherein either means may be operated independently of the other as required but the operation of either means is effective to prevent the operation of the other thereby insuring that the two means may not be operated simultaneously and that one means may not be operated until the completion of the operation of the other.

With the above object in view the invention generally stated, consists in the pro vision of a device, operable by either means in 1ts normal operation for positively preventing an operation of the other and arranged to act on both means in preventing their simultaneous operation and also in certain specific features of structure, combination and relation which will be set forth in detail as the descriptionprocceds.

An embodiment of the invention is disclosed in the accompanying drawings;

wherein j Figure l isa side elevation partly broken away, oia textile fabric measuring machine in which the features of the invention are incorporated.

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2, the upper roller being omitted. 1

Fig. 4 is a detail cross sectional view on the line 4 1 of Fig. 3.

Similar characters of reference designate corresponding parts throughout the several views.

The'fabricto be measured is drawn be tween upper and lower rollers 1 and 2,- one of which, in the embodiment disclosed the upper roller 1, is used as a power roller for the operation of the measuring instrumentality.

The ii'ivention' is not concerned With-the particular structure of the measuring instrumentality and, as a matter of convenience, is disclosed as embodied in a machine which, as to its principal parts, is

similar in structure, organization and mode of operation to the machine disclosed in my pending. application, Serial No. 150,113 and therefore requires scription.

The upper roller is utilized. to operate a drum 3 which carries a suitable chart, a. g. a chart for indicating measured lengths, total price, or both. The drum 3 is mounted on a shaft 4 which is located above and extends at a right angle to the shaft 5 upon which the roller 1 is mounted. The shaft 5, is connected by suitable gearing to the shaft 4 Whose operation is controlled by a clutch having a slidable mem her (i in cooperation with a companion memher 7. the engagement of the clutch members being established by a spring 8 and their disengagement by a slidably manually operated stem 9. Upon the disengagement of the clutch members the drum 3 is zero set by a spring 10, the return movement of said drum being arrested by the ei'lgagement of a lug 11 with which it is only a general de-- provided with a. flied lug 12. The tension to which the outer convolution of the spring 'is secured, said plate being .held in a de sired position by a suitable fastening 15.

Erie of the rollers is mounted in a movable carrier which is operated to space the rollore from one another to facilitate the intro.-

'duction' ofthe fabric into the machine or its removal the:refrom. In the. embodiment dis closed the shaft 5 of the roller 1 has fixedly mounted bea'rings'but the bearings 16 for the shaft of the roller ifiarefitted in a frame 17- which is pivoted. at one side thereof, as at 18,- for movement about a horizontal axis and is pressed upward to hold the roller 2 in operative relation to roller 1 by a suit; b e sprin 19 I Ingthe embodimentdisciosed the frame 17 is lowered 'to space the roller 2 from the "roller 1 by the operation of an arm 20 which atits .free end engages a projection 21 on said frame, (Figs, 1 and 3);; and the frame-is j held "inits lowered pressed pivoted latch by a sp acting with a projection 284m said frame;

Inthe con bodim'ent disclosed .the means for this purpose includes a stationary blade 25 (Fig. 3)

- and a movable blade 26r Tl he invention contemplates the lowering -.of the frame 17 and the-operation of the v blade '26 in independent operations and in' d5 eludes means for preventing" either operation during the practice of the other. The preferred construction in accordance with the till ing; disposedtransversely to the axes of the rollers l and 2; The arm 20. is held against the endof the shaft 29 by a nut 31 on the inner end of the shaft -and the blade 26 is P 3 fifl l yto insure its effective cooperation with the blade 25 by a spring 32 surrounding the shaft 29 and confined between incense the arm 20 and the hub of the blade 26.

lVashers or liners 29 are preferably mount ed on the. shaft 29 in the space between the hub portion of the knife 26 and the adjacent wall of a casing 4:2 to ,be hereafter referred to.

The a'rm20 and blade 26 are provided with angular .tipstanding projections 33 and 3% respectively (Figs. land 3) which are located radially relatively to the" pivots of said armfand blade and said projections havebeveled inner. side faces 35 which mu- I .tually converge ina direction (rearward) opposite to that (forward) in which the arm 20 and blade26 project. The projections 33 and'34codperate with a lock finger '36 ar.- ranged between them. The finger 36 is pivoted-at its rear end for movement in a horizontal plane to a bracket 37 and i's held centered between said projections by fiat springs 38 engaging opposite. sides of its heel pen tion. -A.t its'fronte'nd'the finger 36- is provided with an engaging head 39 which forms a T with the shank or-body of said finger and therefore projects from each side thereof. The head 39 is located very. slightly in ad vance'of the projections 33 and 34: when the I latter are in theirnormal positions and in the path of the beveled faces 35 of said pro-' jections. a

.When the arm 20 is operated to lower the frame -l7"theprojection 33 will be moved forward and in such movement will,' with its face 35,engage the head 39' and move the 1 same laterally into a position wherein it projects immediately .in front of the projection 34 witli'which the said head cooperates as a lockto hold'th'e' blade 26 against 0 erat on at any stage ofthe operation orthe arm 20. In like manner when the blade 26 is operatedthe projection 34 will move; the head 39 into a position wherein it pro ects immediately'in front of the projection 33 with which it similarly cooperates as a lock to hold the arm 20- against operation at any stage of the operation ofthe blade 26. If the the head 39 will wedge between the faces 35 levers 2'7 and 28 be depressed simultaneously and prevent any oper tive movement of I.

either the. arm 20 01' blade 26,

In the embodiment disclosed and preferred the arm 20 bears upon the projection 21 but its bearing end is free and consequently when the frame 17 is quickly raised by the spring 1-9, as above described, the arm 20 is thrown upward. order that its upward. movement may be suitably limited is provided with areal-- .fwarclly pro ecting lug 20 (Fig. 1) which when the arm is raised-cooperates with a fixed stop 20*".

It will thus be seen that either the blade 26 or arm20 may be operated at any period of the operation of the machine as desired but that said elements cannot be operated Sll-ld arm, in."

simultaneously and their operation is-necessarily independent. In this Way conditions which are peculiar to the selling of fabrics For exampie a purchaser order a given length of material and when the length is measured and. the cost. ascertained may change the rder and specify a less or greater length. Such a change can be made Without loss to the merchant when the -material has not been slit or markecl and the capacity of the machine for separating the rollers While the knife is held inoperative isoi advantage in this case, On the otherhand, a purchaser having in mind some special use :ior the material may desire it to be slit or marked at regular intervals to indicate contemplated divisions of the-material. by the operation of the blade flb withoutiinpairing the measuring operation and. without loosening the grip of the rollers l and 2 or removing the material from the machine. Again, with certain kinds of fabric it may be desirable to omit the slitting or marking of the-measured length and in such a case the material is measured and .removed from the machine Without oporation Oil-bi l, blade 28, i
