Description

May 17, 1932. F. HINNEKENS TENTERING FRAME CLIP Filed oct. 15, leso ATTORN EY Patented May 17, 1932 PATENT FLORENT' HINNEKENS, oF PROSPECT PARK, NEW JERSEY TENTERING IFRAME CLIP Appncatin sled october 15, 1930. seria1No.4ss,7s1.

The invention relates to tentering clips adapted for tentering machines, and is of the general nature more particularly set forth, in U. S. Letters Patent No. 1,389,509,

5 granted to me the 11th day of May, 1920.

In the clip disclosed insaid patent, a grip lever is fulcrumed in the end of an arm overhanging a table, the lower edge of one end of said lever being adapted for engagement with the surface of the table; and when the opposite end of the lever is suitably engaged, the said coacting edge will be caused to swing back out of its gripping relationship to a fabric or the like held thereby against the table surface. n

The present invention relates to improvements in the construction and arrangement of the gripping lever, more particularly in that provision is made whereby not only may 2'@ there be effected without dismantling the clip an adjustment between the said edge and table surface in the event of the former becoming shortened as the result of wear and successive sharpenings, but the entire gripping jaw, when operated to release the material, is elevated to thereby eliminate any rubbing or dragging action of the same upon the cloth.

A further object of the invention resides in a construction which will permit of ready adjustment of the gripping angle of the jaw edge with the table surface, as in accommodating dit'ferent thicknesses of fabric.

In carrying out the invention, a. gripping jaw is arranged to be swingably carried or supported to coact with the table surface and to be released therefrom by the action of a lever secured to an oscillatable bushing within which a spindle supporting said jaw is eccentrically disposed.

Provision is made, furthermore, whereby the relative location of said actuating lever may be varied with respect to the bushinw; and whereby, also, said lever is normal maintained in a predetermined position, under the action of resilient means, to secure the desired relationship between the jaw edge and table surface, while further provision is made for readily securing an adjustment of the saine.

Referring to the drawings, the clip comprises a body portion 10 which is bifurcated at its upper part to afford the rigid table 11 and rigid horizontal arms 12 overhanging the same. A swingable jaw 13 is carried by the. arms 12, as hereinafter more fully set forth; and its lower edge is bevel-ed or sharpened as at 14 to coact with the surface of table 11 for gripping therebetween at certain times a fabric (not shown) .which is then released by the said jaw swinging inwardly, all of which is well understood and forms p o particular feature of the present invenion.

'lhe novel features7 however, are embodied more especially in the mounting of the said jaw 13 and in the manner of eifecting its inward movement. As shown in the drawings, the jaw 13 is to this endcarried on a spindle 15 by means of the two arms 16 extending upwardly from the jaw to provide the ,bearings 17, it being understood that said jaw swings freely through said bearings upon the outer ends or journals of the spindle.

These ends, moreover, project beyond bearing members 18 of the arms 12 and adapted to carry the jaw, Vsaid bearings 18 being located preferably adjaoently and between the bearings 17 for the spindle ends. Spindle 15, however, is not mounted directly in the' bearings 18, though passing therethrough; but fits within a bushing 20 which extends into the corresponding bearings 18, and the said spindle 15 being eccentrically located in the aforesaid bushing 20. It will be apparent, therefore, that if bushing 20 be` turned in its bearings, spindle 15 will be correspondingly raised or lowered and the position of the' lower edge 14 relative to the surface of table 11 will be correspondingly altered.

This angular movement of the bushing 20 may be accomplished, for example, by the same means whereby jaw 18 is to be swung inwardly in releasing a fabric. Thus, a lever may be rigidly secured to the bushing as by means of a set screw 21, the upstanding arm 22 of the lever being adapted for engagement with the well-known operating mechanism for the clip. Y

The other and downwardly extending arm 23 of the lever will, when the opposite arm 22 is properly swung (outwardly),

eventually pick up and engage with the jaw 13 to swing the same inwardly and release the fabric, and as indicated by the dotted line position, Fig. 3. However, in view of the particular mounting of spindle 15 hereinbefore described, the outward movement of arm 22 will effect an angular movement of the bushing 2O and will thereby also cause the j aw 13 as a whole to be slightly elevated, thus assisting in the freeing of the fabric and reducing to a minimum any dragging or rubbing action thereon.

The position of the'edge 14 relatively to table 11 is normally maintained by a spring 25, whose one end is attached to the lever arm 22 and its other-end to a lug 26 projecting upwardly from arm 12, to swing the jaw 13 outwardly, that is to say, in a direction tending to bring its edge 14 into contact with the surface of the table 11.

To limit the extent of this wing, an adjustable screw 27, with lock-nut 28, is arranged to pass through the lug 26 with its point29 adapted for engagement with the arm 22. Not only will this limit the extent of rearward swing of arm 22; but it affords, also, a means for adjusting the bushing 2O in its bearings and thereby the relative position of edge 14 with respect to the table surface. This will be of particular advantage when the said edge 14 becomes appreciably shortened due to wear and successive sharpenings, the degree of adjustment, of course, being limited by the eccentricity of the spindle 15 relatively to its bushing. v

I claim:v

1. In a tentering clip, embodying a fabric-gripping table and a coacting gripping jaw swingable about atransverse axis parallel to said table, means for swinging the jaw about the said axis and for simultaneously elevating the entire jaw to vary the distance between its contacting edge and the table surface, comprising a bushing rotatably mounted in fixed bearings of theclip, a spindle eccentrically mounted in the bushing and adapted to oscillatably support the said jaw, a lever secured to the bushing, and means engaging one arm of said lever for angularly moving the same to effect an adjustment of the gripping jaw with reference tothe table.

2. In a tentering clip, embodying a fabricgripping table and a coacting gripping jaw swingable about a transverse axis parallel to said table, means for swinging the jaw about the said axis and for simultaneously elevating the entire jaw to vary the distance between its contacting edge and the table surface, comprising a bushing rotatably mounted in fixed bearings of the clip, a spindle eccentrically mounted in the Vbushing and adapted to oscillatably support the said jaw, -a lever secured to thebushing, means engaging one arm of said lever for angularly moving the same, the other arm of the lever being adapted for contact with the jaw member, and resilient means to hold normally the firstnamed arm of the lever in predetermined position.

3. In a tentering clip, embodying a fabricgripping table and a coacting gripping ,jaw swingable about a transverse axis parallel to said table, m-eans for swinging the jaw about the said axis and for sin'iultaneously elevating the entire jaw to vary the distance between its contacting edge and the table surface, comprising a bushing rotatably mounted in fixed bearings of the clip, a spindle eccentrically mounted in the bushing and adapted to oscillatably support the said jaw,

a lever secured to the bushing, means engaging one arm of said lever for angular-ly moving the same, the other arm of the lever being adapted'for contact with the jaw -member, resilient means vto hold normally the rstnamed arm of the lever in predetermined position, and means to adjust the position of said first-named arm in opposition to the tension exerted by the resilient means acting thereon. v

4. A tentering clip embodying a bifurcated body affording a gripping table at theA inner side of one -arm thereof and an arm overhanging the same, a swingable jaw carried by said overhanging arm to swing about an axis parallel to said table and its lower edge being adapted to coact with the surface thereof; and means for swinging said jaw about the said axis and for simultaneously elevating the entire jaw to vary the distance between its contacting edge and the table surface, comprising a bushing rotatably mounted in bearings of the said overhanging arm, a spindle eccentrically mounted in the vbushing and adapted to oscillatably support the said jaw, a lever secured to the bushing, one arm thereof being adapted for engagement with the swingable jaw, a lug extending upwardly from the said overhanging arm, an adjusting screw threaded therein with its point adapted to contact with the other arm of said lever, and resilient means normally urging said other lever arm in contact with the said screw point.

`In testimony whereof I affix my signature.
