UNTTED TA HERBERT L. ianowiv AND CLIFFORD 0. WHEELER, or NEWPORT; MAINE:

CLOTH-METER.

Specification of Letters Patent:

Patented Feb. 25; 1919.

I To all whom it may concern:

Be it known that we, HERBERT L. BnowN and CLIFFORD G. VVHEELER, citizens of the United States, residing at Newport, in the county of Penobscot and State-of Maine, have invented certain new and useful Improvements in Cloth-Meters, ofwhich the following is a specification. p

This invention relates to the class of linear measuring apparatus and is particularly concerned in the provision of a device for the automatic measuring of cloth web produced by a loom.

As a principal object, it is contemplated by this invention to provide a seriesof dials having pointers and a separate actuating mechanism for each pointer; to provide means in contact withthecloth for actuating the first dial pointer and. to subsequently actuate successive dial pointers after the completion of one rotation on thelpart of the preceding pointer.

A further object is to provide spring means for maintaining the cloth in constant engagement with a toothed roll of p'rede termined circumference for the, actuation of the first dial pointer so that the measuring of the cloth will be automatically undertaken bythe devicein accordance with the passage of the cloth web under the roll.

The above and additional objects which will be hereinafter more specifically'treated, are accomplished by such means as are illustrated in the accompanying drawings,rde-

' scribed in the following specification and.

then more particularly pointed out in the claim which is appended hereto and forms a part of this application.

lVith reference to the drawings, wherein there is illustrated the preferred embodiment of this inventioin as it is reduced to practice, and throughout the several views of which like characters of reference designate similar parts Figure 1 is a vertical sectional view through the casing mounting the measuring means of this invention;

Fig. 2 is a plan view of the same subjectmatter, and I Fig. 3 is a horizontal sectional view showing the actuating mechanism for the various dial pointers.

There is employed a casing 5 which may be readily clamped by some extraneous means, not illustrated, to the breast beam of the loom, preferably between the breast beam and either the right or left liand. temple and has a variety of positions with. respect to the loom which need, be limited only the contact with the cloth web 6 of the" roll 7 which is mountedat. the ,extreniity'of an forming a portion of the: inclosing casing. This roll? is provided upon its periphery 1 with a suitable. number of fine teeth or pins which are adapted to engage the cloth web 6 in positively rotating the roll in exact axle 8. journaled in suitable partitions 9 accordance with the-passage of the'cloth to be measured. A lever 10 is pivoted at 11 between its ends to an ear depending from the casing. 5, and has a long outer arm' depending somewhat from its pivot and -dished at its outer end as at 12- where it underlies the r0117, while. its inner armis normally depressed by a spring 13' tothrow its outerarm.

are provided anum-ber of dials respectively denoted by the numerals 14, '15 and IGr each of which is provided want central aper ture for the reception of a stem 17 which carries the pointerzor indicator finger l8, movement of which over the dials will indicate at all times the true length of the cloth web. The stems 17 are each journaled in the opposite side of the casing 5 and have their central portions enlarged, or as an equivalent construction, provided with inclosing sleeves 19 upon which are secured the gears for operating the respective pointers.

A small pinion or spur gear 20 is carried on the inner extremity of the roll shaft 8 and adapted to mesh therewith is thecrown gear 21 operating the pointer for the dial 14. A stem 22 has its extremities journaled in the casing between the stem 17 of the adjacent dials 14 and 15 and is provided with a plurality of arms 23 which extend over the up per surface of the crown ear in the path of travel of a pin 24: carried y the crown gear. A (pinion 25 is also carried by the shaft 22 an is adapted to mesh directly with the large gear 26 which operates the pointer for the dial 15. A pin 27 is also carried by this last mentioned gear in order to contact directly with the teeth of the spur gear 28 which operates the pointer for the third dial 16. A glass cover may obviously be provided to protect the dials and pointers from the dirt which is usually prevalent during the operation of the loom.

From the foregoing it will be, apparent that 'rotationof the" roll 7 is transmitted to the crown gear through the medium of the pinion 20 and that each complete rotation of the crown gear is registered by a slight movement of the next gear 26 which in turn has its own complete revolutions summed upon the third gear 28. In practice it has been found desirable to provide a roll the circumference of which measures, three teeth of the gear 26-being so arranged as to necessitate 50 revolutionsof the crown gear before completing one of its own revolutions. In like manner the revolutions of the gear 26 are summed upon the final gear 28, which may, however, in many embodiments of the device be dispensed with should the capacity of the loom not exceed 50 or 60 yards which can be accommodated by the first two dials.

I By the use ofthe arms 23 and gear 25 the motion of the pointers 18 for both the dials 14 and 15 is provided in the samedirection and it will be apparent that a similar means may be employed between the dials l5 and 16, when the latter is made use of. If left hand reading meter be desired, owing to some restrictions or limitations of position upon the loom, it is obvious that the cloth web may pass over the toothed roll 7 instead of below the same as shown in order to effect a rotation of the pointer or pointers in the desired direction.

While in the foregoing, however, there has thus been illustrated in the drawings and described in the specification such combination and arrangement of elements as constitute the preferred embodiment of this invention, it is desired to emphasize the fact that such minor changes in the matters of proportion and degree may be made in later adaptations of this device as shall not alter the spirit of the invention as defined in the appended claim.

1 What is claimed is A cloth meter comprising a casing, a shaft journaled within and projecting beyond one end of the same, computing n'iechanism within the casing actuated by the rotation of said shaft, a drum on the outer end of the shaft provided with pointed teeth projecting from its periphery, a lever pivoted between its ends beneath the casing and with its outer arm depending from its pivot and dished at its outer end where it underlies the roll, and an expansive spring between its inner arm and the casing throwing said dished end normally toward the roll, the whole for use substantially as described.

In testimony whereof we aiiix our signatures in' presence of two witnesses.
