IMPROVEMENT IN SEWING-MACHINES.
Specification forming part of Letters Patent No. 38,65Q, dated May 26, 1863.
To all whom it may concern:
Be it known that I, J. l). DALE,of the city of Rochester, county ot' Monroe, and State of New York, have made and invented a certain new and Improved Machine for Sewing by what is called the ruiming stitch and I do hereby declare the following to be a full and accurate description of the same, reference being had to the accompanying drawings, making part of this specification, and to the letters ot' reference marked thereon, the salne letters referring to like parts in all the gures.
Of said drawings, Figure l is a plan of my improved machine. Fig. 2 is a cross-section on red line B B, (red,) Fig. l. Fig. 3 is a longitudinal section on red line A A, (red,) Fig. 1. Fig. 4 is a figure ot' the springclip which holds the end of the needle steady.-
The nature of my invention will be best understood from a description ot' the construction and mode of operation ot' the machine.
In the drawings, Fig. 1, A A are twov rollers, held in close contact by means of the spring s, Figs. 2 and 3, and between which the fabric to be sewed passes, the evennfss or straightness of the seam being secured by means of the gage-plate g, Fig. l. -Between the rollers A A,and in thesmall grcove.(seen passing around them in Fig.v1,) is placed a common sewing needle, whose point lit s toward the right hand, (referring to Fig. 1,) while the e \'^e end rests against the adjustable block B, being prevented trom slipping therefrom by means of the springclip c, Fig. 4, which presses it down. ln front of the point of the needle is placed the cloth-guide D, which is moved vertically by a reciprocating motion, so as alternately to raise thev cloth above and depress it below the point of the needle. The rollers at the same time drawing the cloth steadily through between them, the needle is forced to penetrate the fabric from alternate sides, and thus` produce the same result that is effected by the hands ot' a skillful needle-woman when operating by her fingers what is called therunning stitch.7
lt will be seen that by this process as much cloth as the needle will hold is in a short time worked onto it. When this takes place the point P of the lever L, Fig. 2, is depressed so as firmly to grasp the needle, while at the same time, and by another finger of the same hand, the end e of the spring-clipis depressed, the needle kept free, and the other hand is at liberty to draw the cloth from behind the point where the needle is grasped by the lever L. This being done the needle is ready for a repetit-ion of the filling process.
In similar machines it has been attempted t-o hold the needle by means of the rollers but in this case the ,groove becomes so wornv in a very short time as t hold t none but the very largest-sized needles, while no other plan with which I am acquainted effects the'desired end by means of so few movements.
In order to regulate and vary the length of the stitches and the consequent ineness and coarseness of the work, it is necessary that the gearing which drives the rollers and the clothguide should be so adjusted that while the cloth is passingbetween the rollersthe length of a sti-tch the guide should make a complete elevation and depression. This, of course, is easily accomplished, as the cloth-guide is attached t0 the lever O, which is raised and depressed by means ofthe crankpin on the end of the same shaft which cari-ies the pinion H.
By fitting pinions of different sizes to the shaft M (which is easily accomplished by wellknown mechanical arrangemen ts) ditferent lengths of stitch may be madean object of someimportance, and which it is impossible to secure only by having the feeding and stitching parts ot' the machine running at different speeds.
Having thus described my invention,what I claim therein as new, and desire to secure byV Jona D. DALE.-
