M. W. HAKES SEAM PRESSER June 22, 1954 Original Filed Sept. 11, 1947 Inventor Marie W. Hakes Patented June 22, 1954 UNITED STATES PATENT OFFICE SEAM PRESSER Marie W. Hakes, Eureka, Ill.

1 Claim. 1

This invention relates to new and useful improvements in seam pressers and comprises a divisional application of my copending application Serial No. 773,424, filed September 11, 1947, now U. S. Patent No. 2,606,434, issued August 12, 1952.

The primary object of the present invention is to provide a substantially T-shaped seam pressing member wherein the vertical portion thereof is integrally formed with a U-shaped clamp adapted to removably secure the member relative to a supporting structure, such as a sewing table or the like.

Another important object of the present invention is to provide a small, compact and portable seam presser of the aforementioned character, wherein the hollow horizontal portion of the T-shaped member includes a relatively thin concavo-convexed upper wall, and further wherein this horizontal portion houses a heating element that underlies the wall to effectively heat the same.

A further object of the present invention is to provide a seam presser wherein the heating element is operativelyconnected to a rheostat supported exteriorly of and upon the vertical portion of the member to regulate the current passing to the heating element.

A still further aim of the present invention is to provide a portable seam presser that is simple and practical in construction, strong and reliable in use, neat and attractive in appearance, light in weight, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompaning drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a perspective view of the present invention mounted on a supporting structure;

and,

Figure 2 is a vertical sectional view taken substantially on the plane of section line 2-2 of Figure 1.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral 59 represents a substantially T-shaped member including a hollow horizontal portion 60 and a hollow vertical, upright forming portion 54. The horizontal portion 60 is composed of two elongated concavo-convexed sections 62 and 63 that are removably secured together with their peripheral edges in abutting relationship, by fasteners 64 inserted through bosses 66 formed integral with the upper and lower sections.

The lower open end of the vertical portion 54 is integrally formed with the upper horizontal leg portion 56 of a c-clamp 51 whose lower 1 s portion 59 is formed with an internally threaded vertical aperture 59a that receivably engages a thumb screw 58.

The forward fiat vertical wall 54a of vertical portion 54 is formed with an opening'54b in which a rheostat 50 is suitably held. The rheostat is provided with the usual finger knob 50a, lower terminals 562) and upper terminals 530. A flexible electric cable 20, supporting a plug [8 at its outer end for insertion in a wall outlet l6, extends through a grommet H held in an aperture H a in Wall 54a and its free ends are electrically attached to the terminals 501).

The longitudinal side edges of a substantially rectangular heating element or plate 46 are clampingly held between the bosses on the concave surfaces of the sections 82 and 63, the element 48 having apertures accommodating the fasteners 54. Electric leads 48 are connected to terminals 48a on the undersurface of element 46 and extend downwardly through the upper end of portion 54 and are coupled to the terminals Site.

In practical use of the invention, the G-clamp 51 is slipped over the edge of a supporting structure, such as a sewing table I0, and the screw 58 is manually adjusted to clampingly engage the undersurface of the structure 10, while holding the flat lower surface of leg portion 56 against the upper surface of structure It).

The rheostat is adjusted by knob its to heat the element 46 which will effectively heat the concavo-convexed section 62 upon which a garment will be held for pressing.

Having described the invention, what is claimed as new is:

A seam pressing attachment for sewing machines comprising a hollow T-shaped member having an upper elongated horizontal portion and a vertical portion integrally formed with the upper portion intermediate the ends of the latter; said upper portion being composed of upper and lower concavo-convexed sections; bosses formed on the concave surfaces of said sections; a heating plate dividing the upper portion into two compartments; the bosses of said upper section resting against the upper face of said plate and the bosses of said lower section resting against the lower face of said plate; fasteners extending through the bosses of said lower section and threadingly engaging the bosses of the upper section to secure the sections together, the marginal edges of said sections against each other, and the bosses against said plate; said plate having apertures accommodating said fasteners; and a rheostat supported on said vertical portion and electrically connected to said plate and to a source of electric current.
