Letters Patent No. 111,199, dated January 24, 1871.

IMPROVEMENT IN BAsTnGu|nss Fon SEWING-MACHINES.

The Schedule referred to in these' Letters Patent and making part of the same.

To all whom iii/may concern Be it known thatV I, FRANKLIN l. Games, of Liberty, in the county of Clay and State of Missouri, have invented a new and usefulImprovement in Basters for Sewing-Machines, applicable also in part as a Ruler and Measnrer, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing forming part of this specification, and in which- Figure 1 represents a partially sectional longitudinal view of a combined baster, ruler, and measurer, constructed in accordance with my improvement; and

FigurelZ, a plan of the same.

Figure 3 is aplan 'of a like device under a'modiied construction of its parts; and

Figure 4, a longitudinal section thereof, faken as indicated by theline a: a: in iig, 3.

Similar letters of vreference indicate corresponding parts. l v

My invention is, in ,its`` general principle or action, similar to the buster described in a previous specification, for which an application for Letters Patent was allowed me June 2, 1870; but this invention essentiallydiiers therefrom in several important particulars. The present baster, like my previous one, hereinabove referred to, is designed las an attachable and detachable device fora sewingmachine, or rather forms a separate adjunct, and is provided with teeth at its opposite ends for insertion within the fabric to be basted, and whereby the fabric is kept smoothly extended and prevented from drawing or puckering. Unlike my former device, however, this one dispenses with a guiding-plate carried by-thc sewing-machine for the basting-bar to =be supported by and slide through, and a jointed and sectional sliding bar is substituted for a rigid one, having a piece ofelastic materialwvith teeth at one of its ends, such diierent construction favoring adjustment in the stretch or elastic hold on the goods by the devicc. This sectional sliding bar is likewise provided with face-teeth intermediate of its length',for restraining the fabric from pull or stretch laterally out of the lineof seam, and is reversiblev to adapt it to a continuous length of seam over and above its whole length. Combined with said bar also, if desired, is a ruler and measurer, the same serving. as a, convenient carrier and means forhandling the basting-bar and as aruler for marking out the seam and measure'r. form of construction the combined ruler and ineasurer is made detachable from the basting-har, to allow of the separate use of these devices as occasion may require. 4

Refeiring in the rst instance to figs. 1 and 2 of the accompanying drawing- A represents the basting-barA or baster proper designed to lie lengthwise with the seam on the fabrics Under one in and during the support and feed of the latter over the cloth-table of the machine. This bar is made up of jointed sections, of which there may be'any desired number; but three jointed sections will suice,

namely, a central and two end ones, with a sliding provision under the control of a spring or springs in one or more of such sections for securing'to the bar an elastic action in the straightening of it out when setting it to its hold on the goods.

Thus the central section a of the bar may be made rigid orsolid, and be jointed, as at l) l1, to a divided or tongue portion, c, of either end section, to secure to the basting-bar its necessary iiexure under limit, if desired, 'of stops d d, as more clearly represented by dotted lines in iig. l.

These tongue portions c of the end sections are made to t socketed extensions c e, within each of which is arranged a spring, f, to secure to the bar its necessary elastic grip or action, each of said end portions c preferably being slotted and controlled by a stop-piu, s. If desired, only one of the bar sections (central or end) may .be fitted in spring and socketed vconnection with the adjacent section to secure alike result.

Each end section or portion cis armed at its end with a cross row ot' teeth, g, which, after the fabrics have been properly straightened on the table and the` bar A suitably liexcd, are, in the application of the bar to the seam to be produced, made to enter the fabrics, and on straightening out the bar caused to stretch and hold the fabrics in a iii-m but elastic manner, the stretch being regulated according to the 'quality and condition of the goods by the degree of dex-- ure given to the bar when or prior to inserting the teeth g g.

Said baster travels along with the cloth as theseam is being stitched, and, after a certain length 'of seam has been run, may be turned over by detaching one of its ends from the cloth and made to retain its hold upon the cloth in the same li'ne for a continuance of the seam, both faces of the bar being similarly constructed, so as to-admit of such reverse or repeated.

use of it without endangering its being displaced from its proper line or course by reason of its one end remaining in the goods when. reversing it.

To effect a more perfect and smooth extension of the goods and prevent them from being puckered or drawn out of line, as, for inst-ance, drawn curvilinearly by pull on the goods from under the bar between its ends, the face or faces of the bar may be provided with teeth la la., which .hold on the goods between the ends of the bar when thelatteris extended.

Connected with the baster A, by screws i i passing through slots la la in the end pieces c e ot' the bar, so

as to provide for exure of the latter, is a ruler and y measurer B, which, when attached to the baster'or bar A by the screws 'i fi, serves to carry and give additional heft to the baster, and to give it a broader bearing on the cloth also, to facilitate the handling ofthe baster, which likewise may be used as a .ruler for setting out the seam and as a ineasurer generally, so useful and necessary in the performance of certain work. For these purposes of ruling and measuring vthe bar B may, by slackening or takingout the screws i t, be detached from' the baster A, and to facilitate the handling of it, either'when'detached from eircom-Y bined with the bastel', it may be provided with a handle, Z, which latter it is preferred to attach, subject to draft inward by a spring, u, so lthat said handle may be made to lock with the bar A wh`en extended to hold said bar from accidental flexure, but which handle may be drawn out or retracted against the pressure of the spring u when it is required to provide for exure or .detachment of the baster.

In gs. 3 and 4 of the drawing the basting-bar A vis shown as combined with the ruler and ineasurer B in a permanent manner by being let into the body of it, the whole being reversible to provide for a continuation of the seam, as hereinbefore described, and the central section a being jointed, as at b l), to end portions c c, the one of which is slotted, as at L', and works on a pivot or cross-piu, j, projected through the ruler and measurer, while the other end portion c is of a tongue-like construction and ts within a socketed portion'of the ruler and measnrer B, said sock- Y What I'clairnyand desire'fto secure by'fLeterswPatif l. rlhe baster or basting-barA, made up in sections jointed together, as described, and one or more of said sections made capable of slidi'hg, subject to sprin g pressure or control in direction of the length of the bar, in combinationwith the teeth g at the extremities of the end sections, substantially as specified.

2. rlhc combination ofthe teeth h on the face or faces ofthe sectionally-slidin g and jointed basting-bar A, with the teeth g at extremities of the end seetions, essentially as shown and described.

3. The combination of a ruler and ineasnrer B with a basting-barA, constructed in sections, for operation as herein described.
