To all whom it may concern.-

Be it known that I, JOHN B. Haennniiorrnn, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Quilting-Machines, of which the following is a specification.

This improvement consists in certain combinations of parts whereby quilting of desirable patterns may be performed.

In the accompanying drawings, Figure 1 is a front view of certain parts of a quiltingmachine embodying my improvement. Fig. 2 is a plan of a portion of the needle-bar. Fig. 3 is an end view of the machine. Fig. 4 is a plan of a worm and worm-Wheel comprised in the machine. Fig. 5 is a side view of a portion of a friction-wheel and dogs comprised in the machine. Fig. 6 is a diametrical section of the friction-wheel and side view of the dogs. Fig. 7 is a top view of a cam and bowls or rollers, whereby a carriage comprised in the machine is shifted laterally to and fro. Fig. 8 is a top view of a cam and afinger operating in conjunction therewith, whereby the feed of the work will be regulated. Fig. 9 is a view of a portion of a friction-wheel comprised in the machine, with dotted lines marked on it to illustrate the extent of the movements of the wheel. Fig. 10 is a plan view of two cams used in the machine, showing their relations and illustrating by dotted lines the extent of the movements that result from them; and Fig. 11 is a diagram illustrating the move ments which produce a pattern.

Similar letters of reference designate corresponding parts in all the figures.

Referring first to Figs. 1, 2, 3, 4, 5, 6, and 7, A designates the needle-bar of the machine. The needles a which it carries are arranged in two rows, and so disposed that the needles of each row are opposite the center of the spaces between those of the other row. The needlebar reciprocates up and down, and is guided during such movements in the usual or any other suitable manner. lts reciprocating movement is derived from arms 13 on a rockshaft, 13, and links B connecting the arms to the needle-bar. The rock-shaft is operated by rod 13 connected to a crank, 12, on the said rock-shaft, and acrank, 0, upon the drivingshaft G O of the machine. This driving-shaft is made in two longitudinal sections, connected by a coupling, 0 so that they will turn in unison, but so that the section 0 may move longitudinally independently of the section 0. The crank c is arranged upon the section 0.

The needle-bar, the rock-shaft B whereby it is reciprocated, and the section 0 of the driving-shaft, are mounted in bearings in a carriage, D, that is capable of being moved latorally to and fro. This carriage will be provided with looping or shuttle mechanism operating in conjunction with the needles to form stitches. Such mechanism I have not shown, because it may be of ordinary kind and operated in the usual way.

The section 0 of the driving-shaft O O is provided at the outer end with the usual fast and loose pulleys, O 0 for the reception of a belt, through which such shaft is to be driven. It'also has mounted on it a worm, D, which engages with a worm-wheel, D mounted upon an upright shaft, D journaled in the stationary part of the machine.

On the lower part of the shaft D :a cam, D, is affixed. This cam works between two bowls or rollers, D that are mounted upon studs or shafts arranged upon an extension of the carriage. The periphery of this cam is composed of a number of steps, here numbered consecutively from one to twenty, and serving to cause movements of the ca riage D for producing a corresponding number of stitches in quilting the pattern, of which arepresentation is included in the diagram, Fig. 8. The several steps of this cam are concentric with each other and with the shaft D on which the cam is mounted. The movements of the carriage D which this cam produces are lateral step-by-step movements, causing the shifting of the needles over different parts of the work to be quilted. By referring to the representation of the cam shown in the diagram, Fig. 10, and observing the dotted lines that are coincident with the steps of the cam, it will be understood that the first ten steps of the cam are arranged progressively at greater distances from the shaft on which the same is arranged, and that the second ten steps are arranged retrogressively at less distances from the shaft. Owing to this the carriage will be moved step by step successively greater distances from the 1o abrake-strap, f.

commencement of its lateral travel to the end thereof. "While the carriage D is thus moved laterally over the work the latter is moved or fed longitudinally under the carriage. The work duringits longitudinal feed passes .up over a breast-piece, E, from a roller or from the floor to and between feed-rollers F F. On one journal the roller F has mounted upon it abrakepulley, f, around which passes This brake-strap is fastened at one end to the fulcrum of a lever, f and at the other end to the rear arm of this lever. The forward arm of the lever has a weight, f adjustably hung on it. Bythis I 5 mechanism the feed-rollers are prevented from rotating, except when they are desired to rotate. The feed-roller F is mounted in stationary bearings. The roller F, however, is supported in the forward arms of levers f", which are fulcrumed to the stationary part of the machine, and at the rearends are connected to springs f The force of thesprings f may be varied by adjusting-screws. f, to which they are connected. The screws 1 are 2 5 fitted in tapped holes in standards f erected on the stationary part of the, machine. Thus the roller F is forced toward the roller. F, so.

that the two rollers will grip the work properly to enable them to feed it forward; H

On one journal of the feed-rollerFis affixed a friction-wheel, G. Motion is imparted to this friction-wheel by a lever or arm, G, hav: ing attached to it near one end arod, G?, that.

is also connected to one end of a lever, G

roller F, to which the friction-wheel G is affiXed.- I G designates dogs,-whichvembrace a rim with which the friction-wheel .is provided 0 and impinge against shoulders g onthe. lever G Springs G connect the outer portions of the dogs G with lever G. Whenthelever G is rocked in one direction, the dogs. play freely along the rim of the friction-wheel G; but when the said lever G is moved in the reverse direction the dogs G grip the rim of the friction-wheel G and impart motion to the said wheel.

The lever G is operated by an. eccentric, G mounted on the section 0 of the driving-v shaft 0 O. The lever G consists of a .rock shaft, 9, journaled in bearings on the stationary part of the machine, an arm, 9 affixedto. such shaft and bearing against the, eccentric 5 5 G and an arm, having-the rod G connected to it. The lower arm of 'the lever G is drawn toward the eccentric by a spring, 9

The lever G has a third arm, 9 which may be made separate from the other arms and 6c mounted on the rock-shaft. aforesaid like the other arms. This third arm, 9, operates in conjunction with a cam, H, that is; affixed to. the upper part of the shaft D This cam prevents the lower arm, of the lever G.

65. from always following the eccentric back, when the periphery of the latter recedes, as

the shaft D far as it would otherwise do, and therefore said cam prevents the eccentric from always shifting the friction-wheel G as far as it would otherwise do. This cam consequently regulates the action of the eccentric. The periphery of this cam is composed of steps which are concentric with each other and with It has two similar series of steps numbered from one to twenty.

The operation of the eccentric is so regulated by the cam H that the lever G and dogs G will move the friction-wheel G, and consequently the feed-roller F, various distances.

The feed-rollers are made to run in unison by means of gear-wheels f B on their journals.

The varying feed which the work derives step by step and the varying distances which the needles in the. carriage D are moved laterally step by step over the work, results in stitching zigzag curved lines and in the formation of a pattern. and D different patterns may be made.

By varying the cams H V In Fig. 9 I have illustrated by dotted lines each of these cams during a half-rotation. In

Fig. 11 I have illustrated by two sets of dotted lines each numbered from one to twenty the movement which the work derives and the movement which the needles receive. I have also here illustrated. by circles the positions.

which a needle will have relatively to the work during twenty stitches. Of course it will be understood that the needles do not travel in curved lines, but that the positions illustrated will occur as a result of the combined movements of the needles and work.

I am aware that quilting-machines have been made with feed-rollers having an intermittent rotary motion, said motion being imparted thereto by'a pawl carried upon a lever and adapted to engage with a ratchet-wheel having, teeth at uniform distances apart, which ratchet-wheel is secured upon one of said rollers, an eceentricbeing employed to impart an up-and-down motion to the lever. In this device, also, the pawl-lever is intermitten ly but uniformly raised high enough to prevent it from having contact with its operating eccentric. By my arrangement I am able to secure an accurate feed, while the feed-rollers for producing a lateral movement between the needles and work, a friction-wheel, G, a lever or arm,, G, mounted on a shaft, 9, which is separate and independent of the shaft upon which the friction-wheel is mounted, a dog,
