Specification of Letters Patent.

Patented Apr. 25, 1911.

Application filed October 5, 1910. Serial No. 585,354.

of which the following description, in connection with the accompanying drawlng, is a specification, like characters on the draw ing representing like parts.

In United States Patent No. 765,687, granted to me July 26, 190i, the construction is particularly designed to prevent inor to the movable jur to the roll-pivot thread-cutting blade, and to that end the outer end of the cap is provided with a transverse slot in which the fixed andmovable cutting blades are located.

The inner wallof the slot is made thick in order that a threaded hole may be formed in it for the reception of a roll-pivot, the latter being screwed into the hole and being supported by the wall, the head of the pivot sea-ting in the counter sunk outer end of the hole; The outer end adjacent the inner face of the pivot-supporting wall, and is quite a distance from the blades, so that the latter cannot cut the fill ing-end as close to the edge of the cloth as could be done by earlier forms of thread cutting temples. While this greater distance of the blades from the edge of the cloth was not desirable the tendency of the movable blade and the adjacent roll-pivot to be clamaged was still, less desirable, and hence the structure embodied in my patent aforesaid has gone into extensive use and has proved completely successful in every way except that the cut-ting action of the blades is not as near the selvage of the. cloth as is desirable in manycases.

In my present invention I have provided novel and simple means for overcoming this objection while retaining the desirable features present in my previously patented structure. This I attain by eliminating the thick wall which supports the roll-pivot, which wall heretofore has formed an integral part of the cap of the temple, and 111- stead I mount the roll-pivot on a depending ortion of a thin metallic hanger detachably secured to the cap. Such depending iportion extends into the cap between the cutting blades and the adjacent end of the roll, and can be made so thin that said roll ofv the temple-roll 1s approaches very closely to the blades, so that the cutting action is effected immediately adjacent the selvage of the cloth.

The roll-pivot is a stud which is riveted fixedly to the depending portion of the hanger, so that the latter can be made very thin without detriment, and should the pivot or the hanger break new parts can be substituted quickly without detriment to the rest of the temple head. In the. patented structure hereinbefore referred to if the pivotsupporting wall breaks the cap of the temple is rendered worthless, as such wall forms an integral part of the cap casting.

The novel features of my invention will be fully described in the subjoined specification, and particularly pointed outin the following claims.

Figure 1 is a top plan view of a cutting temple and its stand embodying my present invention; Fig. 2 is a partial longitudinal section and elevation of the templehead, the section being taken on the line 2-2, Fig. 1, looking toward the left; Fig. 3 is a perspective view of the outer roll-pivot and its hanger, detached from the templehead; Fig. 4 is a perspective view of the temple-head to show more clearly a clearance for the edge of the cloth adjacent the outer end of the roll, to be referred to.

The temple-stand A, the temple-head comprising the pod B, cap B and heel B attached to the pod, and the toothed roll 13 between the pod and cap and turning on pivots, and the slide-bar or shank B, are in general substantially as shown in my patent hereinbefore referred to except as to such novel features as will be pointed out hereinafter. The pivotal'support 1 for the inner end of the roll B is of usual construction. The thickened outer end 2 of the cap has in its top a longitudinal, shallow seat 3 terminating at its inner end in an opening 4,- and in said seat is inserted the head 5 of an L-shaped hanger,- shown separately in Fig. 3, and made of relatively thin but stiff plate metal, the depending portion or foot 6 of the hanger extending through the opening l and downward within the cap and pod toward the bottom of the latter. 1

As best shown in Fig. 2 the foot 6 of the hanger is parallel to the inner, upright face of the thickened end 2 of the cap, leaving an upright space or clearance 8 in which are located the fixed cutting blade a and threadnmy ree A the con'structidnnio the cuttingblades and their operation herein s the same as in w my patent; and involves no novel features any further description is' deemed unneces- I sary. in this application.

7 extended inward at right angles thereto a The depending foot 6 ofthehanger has fixedly secured to it, as by riveting, a stud and forming the roll-pivot for the. outer end of the toothed roll B as clearly shown in Fig. 2. A screw 9 passed through a hole 10 in ,the'hangerhead andyinto-the end 20f .the cap s es to maintain the hanger trely in p As the stud ,7 cans-Le securely fixed to the hanger foot the hanger can be made quite thin, so that the dis'tance between the cutting blades and g-th'e outer endof the roll B is very short, thereby enabling the blades to cutithe' filling-end very close to the selva'ge of the cloth, which is highly desirable inv weaving many kinds of cloth. It is not possible to reduce this distance. in my patented temple, because the wall, (marked 45 in the patent), must be quite thickto enablethe' threaded; hole to be made thereinfor the reception of the roll-pivot, and as it is a part of the casting forming the cap thepivot cannot be securely riveted to it. It is much easier, also," to cast.

the cap without any intervening wall between the outer end of the cap and the rollreceiving portion thereof, and to provide the; removable hanger and 'its vfixed, rollpivot,las herein, and there is very little'liability of breaking the hanger, while the wall in the patented structure, being a part of the casting, will sometimes break when subjected to heavy strain.

The temple roll stretches the cloth while in engagement therewith, and-between the .outer end of'the roll and the point where the cloth contracts to its normal width there is usually 'a, tendency to curl up the selvage against the part B of the shank B ad- I jacent the'pod; To obviate this curling or turning over of the selvage I have made a-c'learance groove 12 in the upright face of the part B of the shank, the groove decreasing in depth from its-rear end, nearest the roll, to its forward end, see Figs. 1

v and 4. .As the cloth'leaves the roll the selvage travels freely and smoothly in the clearance groove and the curling or turnlng over F1 1, n the heel '10 of said blade-C is partly'shown in Fig. 4, the heel being struck.

by the lay to retract the blade and effect the.

' cutting of the filling-end as the l ay"l$ea .tsup,

in well' known manner.

1 -Having fully described my invention, what 'I claim as new and desire tosecure by Let: ters' Patent is: M

' 1.- A temple-head. apod and .a cap, a' roll carried by the cap, the-latter having a longitudinal seat in theftopofits outer end and an opening at thejinner end of the seat, a hanger detachably held insaid seat and provided with adepending leg ex- ;ttended through the opening into thecap,

a roll-pivot fixedlysecured to the leg, and

fixed and movable cutting blades located in the clearance between the outer end of the cap and the leg-0f the hanger.

.2. A templehead comprising a pod and. a cap, the latter having a thickened outer end and an adjacent opening in {its-top, a hanger attached to the cap and having a depending portion extended through said opening into" the interior of the, cap, a roll pivot carried by such depending portion of the hanger, and fixed and movable cuttingblades within the clearance between said portion of the hanger and the inner face ofthe thickened end of the-cap.

3; A temple-head comprising a-pod 'a nd a cap, the latter having a closed outer end and an adjacent opening in its top, afsubstantially L-shap'ed hanger detachably secured to the exterior of'the'cap' and'havin 'its leg depending into the cap through thet' opening, a roll-pivot fixed on the leg, and fixed and movable cutting blades within the clearance between the closed end of the cap and the leg "of the ha-ngen 4. A tem le-hea'd comprising a pod and a cap, the, utter having'anopening in its top near its .outer end, a hanger made of' thin platemetal'detachably mounted on the cap and having a dependingtleg extended through said opening into the cap, a rollpivot fixedly attached to the leg, and cutting bladeswithin the clearance between the leg ofthe hanger and the outer end of the cap.

In ,testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
