of the arrow when the machine is in operation which form a part hereo andin which li reference characters designate like parts throughout, Figure 1 is a vertical transverse sectional view taken through the central ortion of one of the combing-heads of a machine embodying this invention. Fig. 2 is a similar andenlarged view of the combing-cylinder and associated parts. Fi 3 is a VIGW similar to Fi 2, but showing t e combing-cylinder in a ifferent angular position. Fig. 4 1s a view of the adjacent intermediate portions between two combing-heads looking in the direction of the arrow of Fig; 1 and with parts removedand broken away to show interior constructions. Fig. 5 is a vertical transverse section on lines 5 5 of Fig. showing the re lations of the several shaft-journals and the supports .forthe leather detaching-roller.

Referring to Fig. 1, the frame of the machine consists of a main horizontal girder A, extending the length of the machine for the common sup ort of the several combing heads thereo andv a series of. intermediate upright su ports' 'B, which are mounted on the girder etweeneach of the heads forming the direct supports for the several operating parts. Inasmuch as all of-the heads are identical in construction, only one is herein" fully illustrated; but it will be understood, of course, that the machine may com rise any desired number of them. In the ferred to the combing-cylinder 1 is carried on the main combin -shaft 2, which revolves constantly in fixed bearings in the direction the operation and construction of the sa1d machines are sim lified and their eflficiency materially increased Referring to the accom anying drawings,

- mechanism presently referred to.

gure rep and. the combings or noyls are removed by the usual'means of a cylinder cleaning-brush 3, doffing-cylinder 4, and dofier-comb 5, these parts being suitably driven in the directions shown from the usual gear-head located at one end of the machine (not herein shown) and being also inclosed in a removable casing C. The upper portion of the intermediate supports B are inclined and provided with framearms B, to the extremities of 'which are secured the brackets D and also the brackets E, upon which the lap-roll shafts 6 are carried. Adjacent to these brackets each supporting-arm B carries a ournal-se'at F for thehinge shafts or pins-7 and 8 of the top comb 9 and upper lap-feed roller 10, respectively. The

ing the length ofthe machine, journaled on the support B, and the upper roller 10, is presse against the roller 11 by the springs G,

which are connected between the arms 10 and the bracketsD, above referred to.

ower lap-feed roller 11 is. I formed upon the usual lap-feedshaft extend- The lap is fed intermittently in the'usual manner by the lap-rolls 6 down the apron or chute H into the lap-feed rollers 10 and 11, which rollers are suitably actuated from the gear-head to advance the lap a roper dis tance toward and into the jaws o the nipper The above-described parts are well known in machines of this order and for this reason are not considered to require illustration or explanation further than that already given.

According to the present invention the nipper mechanism just mentioned is stationary with respect to the frame and the several parts of the head; but it is capable, however, of accurate adjustment in difierent direc tions. It is comprised of a nipper-frame 1 2,

which carries the lower jaw 13 or cushionplate and a pair of forked arms 14 14 at each end. The upper movable jaw or nipperknife 15 is secured to the ends of the leverarms 15 15, which are pivoted ona cross shaft 16, carried by the Dipper-frame between the arms 14L thereof, and the connecting-rod- 17 joins the tails of the arms 15' with a cam crank 18, suitably driven by the cam 19. The;

adjustable. su port for the flipper-frame (shown more 0 earlyin Figs. 2, 3, and 5) comprises a pedestal I, forme with a base which is adjustably bolted to the frame-arm B, and a vertical column which terminates in two lateral abutmentarms I (Shown in top view in Fig. 4.) A pillow-block J is mounted to slide verticall on each side of the column I, being adjusta le thereon by means of setscrews J J, secured to rotate without axialmovement in apertures in the abutment-arms I 1" of the fixed column I. The nipperframe is provided With dgeons or pivots 20 at opposite ends, which are respectively seated in the pillow-block at each end of the head and retained therein by means of ordinary caplates. (Shown at J.) The arms 14 14 of t e frame extend upwardly sons to be located, respective] on opposite sides of the abutmen'ts I" an oppositely disposed set-screws 21 21, respectively carried by said arms, engaie with opposite sides of the abut- 2O ments, as s own in the drawin s. By reason of the construction just descri ed the nipperframe 12 and its cushion-plate maiylge rigidly fixed upon the frame of the mac e, butjis capable, however, of a nice adjustment in different lanes. In operation the cushionplate is ocated just clear of the combing-cylinderand at a distance from the detachin and drawing-off rollers, presently describe which is appropriate for the length of sta le under treatment. vThe top comb 9 is a so stationary, being mounted idly on the hinge.

pin 7, as stated, and provided with arm projections 9(i which overlap the abutments I and are a ustably supported thereu on by means of set-screws 22, which there ore determine the extent to which the needles of the top, comb penetrate into the staple which passesbeneat it. In the operation of the machine'the ends of thestaple which project from the jaws of the nipper mechanism are combed by the teeth "or needles of the revolving-needle half-lap 33 in the usual manner and are then engaged by the detaching half-la or fluted se ent 34:,v

which cooperates wit the leather etachingroller 23 to separate the staple from the lap,- at the same time dragging it through the row of teeth of the stationary top com 9, w 'ch is ad usted to be just clear of the patho the said segment; The staple is then overlapped orpieced upon the tail ends of the last revi-'. ously combed staple and passes as usua from between the intermittently-rotated detach.

It wil be observed frqm Fig. 4 that there is a bracket-arm, such asL at the opposite ends of each head of the machine and that their function is to serye as a fixed, al-' though adjustable, support for the leathercovered detaching-rollers 23. The latter are formed in the ordinary manner with their gudgeons 25, surrounded by sleeves 26, which rest against the inclined u of the fixed bearin '-blocksM, an .t e leatherer surface covered body oft e roller rests I against the fluted body portion of its dr wing-0H roller 24, as indicated in'Fig. 3 an also as shownin dotted. lines in F 5.

the other rollers at any desired distance from the combing-cylinder. The clearing-cover 32, which has its bottom side lined with soft material, like felt, is supported in notches in the horsetails at each end of the head and the clearing-off roller, thereby not only prov tecting the interior parts, but also preventing the draft of air which the revolving cylinder tends to produce around the leather detach- Moreover, the mounting of the detaching-roller 23 upon fixed supports, which are formed close to and as a part of the frame-supports B, renders it possible to locate the stirrups 27 and horsetails 30 at wider distances apart, which permits the brass clearingoff roller 29 to. have as lon a working face as the other rollers, thereby 1ncreasing the width of the lap without increasing the distance between the intermediate su orts B.

e combing-cylinder has its needle halflap 33 formed with rows of combing-needles secured to it in the ordinary manner, so that their points determine a locus which is cylindrical and concentric with the shaft 2, and at its opposite side it carries a detachin half lap or segment 34, shown herein as uted, which is also cylindrical and concentric with the shaft 2, but the radial distance between theexterior surface of the segment and the axis of the shaft is reater by a slight differenceapproximately one-sixteenth of an inc7.1than the radial distance between the locus of the needle-points and the axis of the shaft, so that the segment is radially higher on the combing-cylinder than the points of the needles. This difference in radial height of the segment over the needle half-lap permits it to engage with the detaching-roller 23, which is so adjusted on its fixed supports that its staple-engaging surface is located in a fixed position just clear of the needles. At the moment of engagement the roller. 23, which is driven by reason of its constant frictional contact with the drawing-off roller 24, is being rotated at the same surface speed and in the same direction as the segment, and the free ends of the staple which roject from the nipper-jaws are caught an nipped between the segment and roller, being thereby detached from the lap and .carried over toward the drawing-off roller 24, where they are laid or overlapped upon the tail ends of the previously-combed staple, as above described. In practice itis impossible for an effectual nipping-pressure to be obtained be tween the segment and detaching-roli within one or the other of these parts. This yielding movement, which may be very sli ht, is preferably allotted to the detachingroiler, for which purpose the latter is held by the yielding pressure of the weighted stirrups on its fixed end su ports and against the roller 24, as above ful y described, and the forward edge of the revolving segment is beveled, as shown at 34, so that it will run under and engage the roller without undue shock. It is found to be satisfactory to adjust the detaching-roller 23 about one thirty-second of an inch from the path of the needle half-lap, and the beveled edge of the fluted segment has therefore but to liftthe roller the additional thirty-second of an inch in order to bring it into pressing engagement against its cylindrical surface. While the detachingroller actually does have a slight lateral movement, yet such movement is only a movement 0 yield such as must necessarily exist between any two parts which are ada ted to nip and pinch an article inserted etween them. For practical taching-roller is substantial stationary or fixed, and in the following c aims I have so referred to it as distinguished from other machines in which it is moved laterallg first into engagement with the segment an then out of the path of the needles. When the sta le has been detached and conducted into t ; e rollers 23 and 24, the latter continue their forward rotation and then immediately reverse and rotate backwardly about one-third of a complete revolution or one-half of their forward rotation in the usual manner, during which operations the nipper-- knife has opened and the lap has been fed forward a pro er distance by the mechanism alreadydescri ed. 'B the time thenipperhas again closed the nee le half-lap Willhave revolved around and again begun its action on the staple projecting therefrom. By reason of the fact that the lower nipper-jaw or cushion-plate 13 is normally fixed in its proper position with respect to the cylinder and does not, therefore, have to be depressed in order to carry the projecting staple toward the cylinder the time required for the nipper mechanism to get ready for the needle halflap, as well as the power required to operate the nip'per mechanism, and the vibration of these parts, are reduced to a minimum. Moreover, the leather detaching-roller 23, having its fixed position of action out of the range of the needle half-lap,'is immediately in position for the next detaching operation as soon as the back edge. of the fluted seg+ ment has left it, and the time and mechanism heretofore required for moving it from one position to another are accordingly reduced.

This consideration in respect of eliminatin movement of the several parts, and thereby savin time, permits the interval on the out providing fora certain amount of yield i combing-cylinder between the needle halfpurposes the deber of moving parts and the extent of their movement ada ts the machine for running at high speeds wit economy and efficiency.

The stationary top comb is located as close as practicable to the ni per-knife, and its row of downWardly-pointe teeth is immediately superior to thetuft of staple projecting from be ow the same. During the combing operation the staple remains in this relative position beneath the comb but it is subsequently raised by the comparativel high detachingsegment into the teeth of t e comb, so that the tail ends of the staple, which have been held in the grip of the nipper-jaws, are certain to receive a thorou h combing or straightening as they ipass f orwardly to the piecing mechanism. he comb is free to be swung back on its pivot 7 whenever desired for the purpose ofremoving the dirt and lint collected by it.
