Z '0 all whom it may concern:

Be it known that I, EZRA Dixon, a citizen,

of the United States, residing at Bristol, in the county of Bristol and State of Rhode Island, have invented a new and useful Improvement in Top-Roll Saddles, of which the following is a specification.

This invention relates to certain new and useful improvements in a top roll saddle, and especially to that type employing a back saddle having only a bearing on the back roll, the middle roll being untouched by either the front or back saddles, and while the invention is particularly adapted for this type it is also capable of embodiment in back saddles bearing on either the back or middle rolls or both, such as is illustrated in my Patent No. 10877 3 1, issued February 17 191 1.-

The invention resides in the formation of a lock between the front and back saddles which will necessitate relative movement other than rotation about the axis of one saddle by the other saddle, this being accomplished in the present instance by forming a knob on the end of the front saddle to enter a socket or opening in the back saddle on relative angular movement for connecting. the two saddles.

The invention further resides in the features of construction, and the arrangements and combinations of parts described in detail in the following specification and succinctly defined in the appended claims, reference being had to the accompanying drawings vrherein Figure 1 is a side elevation of the improved saddle construction as applied to a spinning machine, the latter being in fragment.

Fig. 2 is a detailed section on line 22 of Fig.1.

Fig. 3 is a fragmentary side elevation of the saddle construction showing particularly the improved lock, and

Fig. 4: is a top plan view of that portion 7 of the saddle illustrated in Fig. 3.

Referring more in detail to the drawing, the numeral 1 indicates the front roll saddle which rides the front roll 2 and is formed with a rearwardly extending shank 3 termibeing peripherally recessed, as at 5, adjacent and in advance of the knob to reduce the diameter of said shank at this particular point.

. Y Specification of Letters Patent; I t t dM 7 191 The back saddle is adapted to, ride either theback roll 6 or the middle r0117, a lateral lug .8 being formed-on theeshank 3 between the recess and. the saddle bodyproper past which the back saddle is movable for assuming operative relation with either roll. '2 This back saddle 9 has suitable roll-straddling means 10 on its lowerside and is pro-; vided with. an upstanding arm 11 at itsrear edge, said: arm being formed with an aperture 12 and a slot l3 leading therefrom upwardlyrthrough the upper end of said arm. In applying-{the backsaddle to the shank of the front saddle, the latter is held in an upright position, or so that the shank will extend at right angles to the back saddle, with the peripheral recess 5 facin the inner side of the arm. The shank is t enmoved laterally to engage one of the opposing fingers 14 in the recess 5 and the knob 4 disposed in the aperture 12, as depicted indotted lines in Fig. 3. The-front saddle is then swung down to the full lined position and dropped from out the slot 13 into the aperture 12 in which latter the shank is freely rotatable and slidable. The front saddle is then turned to bring the saddle proper into a downwardly-facing position, the extent of rotation in this instance being substantially a quarter turn, as indicated in Fig. 2. p

In its operative position, the back saddle is supported off the shank by the wall 15 formed on the opposite end of said back saddle. When it is desired to seat the saddle on the middle roll, the saddle is turned an additional quarter revolution to brin its slot 13 in alinement with the lug 8, w ich latter is disposed on the opposite side of the shank from the recess 5, and shifted longitudinally of the shank past the lug to the dotted line position indicated in Fig. 1.

It will therefore be noted that the saddles are angularly related in applying the back saddle to or removing the same from the shank, the swinging movement being in a plane longitudinal of the shank so that there is practically no possibilit of either becoming disengaged one from t e other.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a top roll saddle construction, a front saddle having a rearwardly extending shank formed on its extremity with an enlarged knob and a recess adjacent thereto on one side of the shank, a laterally extending lug formed on the opposite side of the shank and spaced forwardly of the recess, and a back saddle having an upvvardly extending arm formed witha shank receiving aperture, the latter having an entrance slot leading through the upper end of thearm to provid sp ced ng r f r g g ngin the'f recess of the shank on removing andmount:

ing the back saddle over theknob from and to operative position on theshank.

2.-In a top"ro1l sadd1'e' construction, a front saddle having a rearvvardly extending shank terminating in a knob and formed With arecess adjacent the knob, a lug provided on the shank in spaced relation to the recess and staggered relative thereto, and a back saddle having an upstanding armbifurcated at its upper end to engage in the shank recess'to' permit movement of the backsaddle from and to operative position ontheshank;

' 3'. In'atop r011 saddle, a front saddle and a back saddle, holding means on the'back Copies of this patent may be obtained for saddle, and means on the front saddle engageable With said first named means when the saddles are at relatively right angles,

said means being "formed to efiect locking of the saddles upon relative pivotal movement 'following said right angular disposition.

'eLJ'In a top roll saddle construction, a pair of saddles, one having a shank formed With a side recess adjacent its end and the other having an opening receiving the shank and defined by an overhanging part movable into theiecess to permit the end of the shank being swung through the openingto, disconnect the saddles. v

In testimony whereof I have signed my name to this specification in the presence of tWo subscribingwitnesses.

- EZRA DIXON.
