Letters Paten of the United States were granted to me 0 the 29th day of May, A. D. 1866, foran improved knitting-machine.

In-the followingspecitieation it has been found necessary to describe and'represent sundry of the parts, if not most, of the said machine, in orderto fully show the application of my present improvements'. I therefore desire it to be understood that I do not herein claim any of the features, devices, or combinations as set forth and described in such patent, but limit my present invention to the principles or combinations asvdened in the claimsy at the latter part of this specification, such claims to which reference' 4may be had serving to exhibit the nature of 'my present invention.

The first part of my 'invention relates to the -combination of the cone .and loop-forming devices with thewheel F, hereinafter mentioned, and employed for operating the comb and other parts appliedto such Wheel. y

Another part of myinvention relates to the combination ofthe eye-pointed needle,r the vibrator-y looping-hook, andthe comb, the.

looper or looping mechanism operating to take the loop from 'the needle and deliver and ltransfer it to "a tooth of the comb, substan-y Finally, myinvention further consists in a Aknitting-machine composed of lall the devices` or-instrumentalities shown in the accompanying drawings, and hereinafter described, when constructed, combined, and used substantially in the manner and for the purposes asspecified. v Having thus premised, I will .now proceed to explain the machine and theparts thereof which I consider as new and of my invention.'

Motion is imparted to my machine by va drive-Wheel, B, revolved by any convenient means. This wheel has a'groove on its periphery to receive an expansible wheel or fric` tion-gear, E, rigidly set uponrthe horizontal' shaft D. This shaft D also carries 'the wheel F, which moves the rack, needle, and looper, and also, in connection with the slides Q G', reverses the motion of the rackwhen desired, and as arranged by the operator.

A denotes the base or platform of my machine.

The shaft D is supported upon proper stand-V ards,one of which, I, also holds suspended Iat one side of the wheel F both the needle and looper', arranged in their respective carriers. These carriers are attached to sleeves through which pass supporting bolts or journals, which bolts are attached or secured 'to the standard or support I in such a manner as to allow of the free vibratory motion of both looper and needle.

h shows the sleeve to which the arm or carrier of the looper is attached 5 z', that of the needle-carrier. y

The carrier or arm of the needle is slotted,

`A`as indicated at e in Fig. 1, Plate 4, and the stud or eccentric as, same figure and plate, works in the said slot. Thus, by the revolution of the wheel F a vibratory reciprocating motion is imparted to the carrier t', and consequently to the needle. The path or camgroove y on the same face of the wheel F, (see same gure and plate,) imparts a similar motion tothe looper and its carrier u by means of the stud z working in the said groove or cam.

Upon the periphery of the wheel F, Plate 4, Fig. 3, is placed a projecting edge, r, fixed to the said periphery. The part or n r thereof is movable, and slides a short distance from one to the other side by the turning of the small movable crank or lever w'. When the movable part or fin r of the edge is thus turned to one or the other side by the crank w', the said edge forms a slow screw or helix in one revolution ofthe wheel F, so that as F revolves the said free end or fin r of the edge 1 at each revolution enters a space of the rack a, Plate l, one space or tooth in advance of that one in which the fixed part r of the said edge is traveling, thus advancing the rack af at each revolution ofthe wheel F a distance Aequal to the space occupied by one of the teeth of the said rack. Thus the motion of the rack and comb is obtained.

Set upon the plate, on the edge of which is formed the comb c, Plate 1, arel two slides or dogs, G G. These are held in position by having on their bottoms, on the sides contiguous to the front side of the rack a', lips and grooves which overlap a similar lip, and fit into a similar groove on the said rack. (See G, Plate 2.) Through the hollow cylinder e of these slides G G passes a rod bifurcated at its end 12, (see Fig. 4, Plate 5,) which points or bifurcations fit into the spaces between the teeth of the rack a. Around this rod is coiled a spring, 11. The rod is turned by a thumbpiece, e, on the front end thereof, and on the inner face of this thumb-piece are small projections a5, which it into corresponding recesses b5, (see Figs. 3 and 4, Plate 5,) in the outer or front ends of the cylinders e. Whenthe said projections thus sink into the said recesses, the points or bifurcations of the rod are held firmly in the spaces between the teeth of the rack; but when, by the turning of the thumbpiece, the said projections are thrown out of the said recesses, and the rod revolved, the points or bifurcations are moved or drawn backward somewhat into the cylinder e and partially out of the said spaces. Thus as the rod is turned, these bifurcations or points, by alternately passing into the spaces in the rack, operate as a pinion to move the slides G G along the rack, and on the metal plate or sheet on which the comb is formed, in either l of two directions, as the said rod may be turned.

The coiled spring 1l is so arranged around the rod and inside of the cylinder e as to keep the forked or bifurcated portion of said yrod in contact with the rack a, but admits of the said rod being withdrawn or pulled out of the cylinder sufficiently to disconnect the rod entirely from the rack, and thus allow the slide G to be moved freely along the combplate.

When the thumb-piecee is turned in the ordinary manner, the projections on its inner surface, by being alternately forced out of and falling into their corresponding recesses, serve to indicate to the operator the distance which the slide G is moved. They also prevent the working ofy the machine from turning the rod,klthus serving also to keep the slide in any desired position on the plate. The distance between the two slides indicates the width of the work or fabric. These two slides or carriages Gr G are somewhat diiferent in form, and subserve somewhat different purposes. This will be best understood by reference to G, Plate 3, wherethere are seen on the face 'of the said slide, toward the rack a, two inclined faces or surfaces and a projection, s', and to G', same plate, wherethere is exhibited the projecting arm s. l

By means of the two projections s s the reverse motion of the rack is obtained, and 'in the following manner: When, by the motion of the rack a, either slide is approaching the wheel F, the movable part or fin r of the edge of said wheel is found to be turned toward the said approaching slide or carriage, and when the said' carriage has approached sufficiently near to the said wheel F to enable the projecting parts s or s', as the case may be, to touch the wheel, one of these points s or s comes in contact with the crank or lever lL0', by which the movable edge r is moved, and thus presses the said movable edge to the other side of the periphery of the wheel, thereby causing it to engage the spaces of the rack a on the said other side of the wheel F, and thus reverse the motion of the said rack. Therefore it will be seen that the rack traverses only the distance between the said slides or carriages G G', and hence they in dicate the width of the work to be performed, successive rows of stitches being added to the work by, each traverse of the rack a.

The two inclined faces of the carriage or slide G operate the recording-disk, by which the number of the successive rows of stitches added to the work is indicated.

M is this disk, set and turning in a horizontal plane on an upright spindle, l. The pethe needle and deliver or transfer it to a tooth of the comb, substantially as set forth and specified..`

4. In combination with the sleeve of the needle-carrying arm and its pin, the collar, bolt, and spring, tor retaining the needle-arm in connection with or allowing it to be moved away from its operating devices.

5. TheA slide G, having the mechanism described for changing its position on the comb, and also the projection for operating the arm 4 which moves the recording-disk, all substantially as described.

6. A knitting-machine comb, having the upwardly-curved or inclined teeth, the whole being as and for the purpose shown and hereinbefore explained.

7. A knitting-machine composed of all the devices and instrnmentalities shown in the accompanying drawings and herein described, when constructed, combined, and used substantially in the manner and for the 'purposes specified.
