Tuckers for Se-win gmachines- Fig-4 ttest UNITED STATEs PATENT OFFICE.
ERANCIs W. BROWN, or; CINCINNATI, OHIO;
IMFROVEMENT IN TUCKERS FOR SEWING-MACHINES.
g Specification forming part of Letters Patent N0. 146,377, dated January 13, 1874; application filed August 11, 1873.
To all whom ttMmay concern:
Be it known that I, FRANCIs W. BROWN, of Cincinnati, in the county of Hamilton and State yof Ohio, have invented certain new and useful Improvements in Tuckers'for Sewingi Machines, of which the following is a specification:
Figure 1 is a perspective vieuT of my improvement. Fig 2 is a sectional vieW of the adjustable arms, Fig. 3 is a plan vieW of the top of arm B. Fig. 4 is a plan view of the guideplate G 5 Fig. 5, a plan of the adjustable arm E.
The nature of my improvement relates tO that class Of tuckers in which the material is guided by the adjustment of gages, markers being dispensed with. My invention chiefly consist-s in providing an adjustable arm, which prevents the completed tuck from resting upon the material during its passage through the attachment, thereby causing the work to be done more smoothly and with less attention from the operator.
Other features of my invention will be here inafter described.
A represents the m ain station ary plate, which is secured to the bed-plate of the machine by a set-screw in slot a. c represents the ele- I vated bed, upon which the adjustable arms B C slide. r r represent guides for keeping arms B C froln lateral movement, and these arms are held in position by a set-screw, t, passing through slots o n. Between this setscrew and the arms B O is a thin plate or Washer, which Venables the set-screw to perform its office more etfectually.
It is unnecessary to more fully describe the parts represented by A, B, C', C, and H, as they are fully described in Letters Patent granted to me August l2, 1873.
Instead of employing a hook upon plate B,
as in my former device, I use the gage D.
(Shown in Figs. 1 and 3.) A similar gage may be employed in place of the hook-plate H.
E represents a supportingarm, projecting inward, between arms B and C', through gage D, as shown in Fig. 1. It is made to slide y loosely therein, so as to be adjustable; and it may be secured in any desired position by means of set-screw S. Its office is to separate the fold of a completed tuck from the material, upon Which it Would otherwise rest during the passage of the goods through the attachment, thus serving to pass the same through more freely, smoothly, and with less attention from the operator, and, at the same time, its use enables the tuck to be made more even or true.
The mode of using my improvedtucker is the same as that already described in my previous patent, above referred to, with this change: Arm E is adjusted to project under the completed tuck, While each secondary or successive one is being stitched, a` suicient distance to completely separate each tuck or plait from the material upon which it is folded.
Having described my improvement, what I claim as my invention is The adjustable tuck-supporting armE, arranged to slide in the gage D between the plates B C', all combined and arranged substantially as herein described, for the purpose specified. j
In testimony whereof I have hereunto set my hand this 8th day of August, 187 3.
j ERANCIs W. BROWN.
