v H. w. WINTERS 2,473,085 COVER CLAMP FOR PRESSING MAGHINES Filed Oct. 1, 1947 )NVENTOR. Hora/d W. W/h/ers BY 63k Afiy Patented June 14, 1949 UNITED STATES PATENT OFFICE COVER CLAMP FOR PRESSIN G MACHINES Harold W. Winters, San Francisco, Calif. Application October 1, 1947, Serial No. 777,161
1 Claim.
This invention relates to improvements in cover clamps for pressing machines.
The principal object of this invention is to provide a clamp for holding the cover cloth on a pressing machine buck whereby the cloth will be retained tightly even when the presser head pushes downwardly against the buck, thus preventing wrinkles from forming in the covering, which wrinkles would in turn appear in the material being pressed.
A further object of this invention is to produce a device of this character which is economical to manufacture, one which is easy to apply and one wherein the same will not damage the protecting cover.
A still further object is to produce a device wherein an equal pull will be exerted on opposite sides of the buck irrespective of the pressure applied to the top of the buck.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Fig. 1 is a top plan view of my device previous to placing the same upon the buck.
Fig. 2 is a cross sectional view of the device on the buck and on an enlarged scale and taken on the line 2-2 of Fig. 1, and
Fig. 3 is a perspective view of a pressing machine buck having my invention applied thereto.
In pressing clothes it is common practice to use a support upon which is positioned a padded buck, which consists of a base covered with a spring pressed pad over which a pressing cloth cover is positioned and upon which the goods to be pressed is laid.
These covers have been held to the buck by various methods such as stitching, lacing and the like; however, when the press comes down against the buck the pressure com-presses the springs and causes wrinkling of the cover.
Applicant has, therefore, devised a means for clamping the cover on the buck in such a way that it will always remain tight.
In the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention the numeral 5 designates the buck as a whole, which comprises a base 6 which supports springs 1, over which a pad 8 is formed, and upon this pad is positioned a cover 9, the cover generally being made of canvas The construction thus far described is common and forms no part of my invention.
My invention consists of a pair of substantially U-shaped members II and 12, which are hinged 2 together, as shown at l3 and I4, through the medium of a slip arrangement provided by the slots l8 and a headed pin extending therethrough.
The inner surface of each of the U-shaped members is provided with cover engaging prongs H which are adapted to engage the material of the cover 9, as best shown in Fig. 2. These U- shaped members have a considerable width and therefore extend below the bottom 6 of the buck and have their lower edges connected by a plurality of springs l8 and I9 positioned beneath the bottom of the buck. The springs are in turn connected together by equalizer bars 2 I.
It will be noted that the U-shaped members fulcrum about the bottom of the buck at the point A, as shown in dotted lines in Fig. 2, the result being that when the pressure is placed upon the top of the buck and when the springs 1 are compressed the cover 9 tends to move downwardly and as this occurs, the springs l8 and I9 function to pivot the member II and I2 and to draw down upon the cover, thus holding the cover tight at all times.
It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claim.
Having thus described my invention, I claim:
In a device of the character described, a pair of substantially U-shaped members having their ends in parallel relation slidably and pivotally connected one to the other, the middle portion of each of said U-shaped members having opposed prongs along their upper edges adapted to engage the cover of a pressing buck at a point above the base of said buck, and springs interposed between the bottom portions of said U-shaped members and adapted to be disposed at a point beneath the bottom of said buck.
HAROLD W. WINTERS.
