Application filed September 1, 1921. "Serial 1570491509.
(GRANTED UNDER THE PROVISIONSOF THE ACT 0F MARCH 3, 1921, 41 STAT. L. 1313.) i
To all whom it may concern:
Be itknown that 1, Max Jonas, a citizen of the German Republic, and resident of Berlin S. 42,, Germany, have invented certain new and useful Improvements in and Relatingto Clamping and Stretching'Devices for Trousers (forv which Iliave filed application in Germany June 15, 1920), of which the following is a specification.
My present invention relates to clamping and stretching devices fortrousers and has for its object to provide an improved device of this kind, comprising a pair of spring clamps connected in a particular way with an intermediate hanger.
In carrying my invention into practice,
I use a pair of spring clamps or clips the.
two arms of each clamp or clip being pivotally and frictionally held on a spool shaped pivot-pin, provided with a suitable bore,
having an inner spring and slidably engaged by one side arm of the intermediate hanger, whereby said clips may be moved and held apart from each other after having engaged the lower borders of the trousers fcl r the purpose of stretching the same latera ly.
In my improved stretching device thepiv oting arms of each clip are connected together below said pivot-pin by means of a traction spring secured to said arms by pins passing through the arms of the clip.
Moreover the lower ends of the arms of each clip have their inner faces provided with upwardly projecting teeth and serving to secure a perfect hold of the clipson the.
borders of the trousers.
My invention will be readily understood from the following description taken in connection with the accompanying drawings, wherein:
Fig. 1 is a perspective view of the device showing a pair of trousers, engaged by the same.
Fig. 2 is a perspective view of a clip in 1 Fig. 6' is an elevation of the complete device in its collapsed position. v v
Referring to the drawings, 1,1, designate two springclips, eachof which comprises two arms connected together by. means of a coilspring 2, the ends of which are held in circular openings 3,-provided in said arms,
. Above said coil-spring 2 each arm of the clip has a semi-circular recess to receive a cylindrical spool-shaped pivot-pin 6,. provided with end disks 7 adapted to engage the sides of the arms, whereby. any undue lateral movement of the arms with respect to each other will be effectively avoided. Said pivotpin 6 is provided with a central bore 8, which is preferably rectangular in cross section although it may be of any desired shape to receive the correspondingly. shaped arm 9 therethrough, said arm 9 being frictionally held in said bore by the pressure ofa small spring blade (not shown) secured within said bore 8 in a well known manner. The
inner ends of the arms 9 are pivotally connected to a supporting block 10 which isprovidedwith the usual hanger 11 Thus it will be seen that said clips l are adapted to be shifted along said arms 9 and this arrangement forms an important feature of my invention. i
The operation. of the invention will be readily understood from the construction above described.
The arms 9 of the hanger being in their horizontal positions as shown in Fig. 1 and the clips 1,1 arranged on said arms, the borders of a pair of trousers may be clamped between the jaws of said clips as shown, whereupon said clips will be shifted apart I from each other on saidarms 9 to stretch the borders of said trousers.
As shown in Fig. 6 the arms 9 may be moved in vertical parallel positions, whereby the device may be easily packed.
I wish itto be understood that minor details of construction may be changed without departing from the scope of the invention.
Having now fully described my said invention, what I claim and desire to secure by Letters Patent, is:
1. In a device of the class described, the combination with a hanger having a pair of arms thereon, of a spool slidably mounted on each arm, a pair of arms for each spool, each arm engaging the spool on an opposite side, and resilient means connecting the arms of each pair and serving to pull said arms together, so that the arms will engage the spool and the free end of the arms will be drawn toward each other forgripping material to be held.
2. The combination with a licnger of a pair of spools slidably mounted thereon, a pair of arms for each spool having a bearing portion between the ends for engaging the spool and teeth formed on the innerfaces at one end portion, and a spring connecting the arms of each pair positioned between the bearing portion and the toothed ends,
newness whereby the spring will draw the arms together so that the teeth will engage material to be held and the bearing portion will engage the spool.
3. The combination with a hanger of a pair of cylindrical members slidably mounted thereon, a pair of arms for each cylindrical member, each pair of arms being formed with teeth on the inner side adjacent one end, and cylindrical bearing portions between the ends for engaging the periphery of the cylindrical members, and a spring connecting the arms of each pair between the toothed portion and the bearing portion for drawing said arms together so that the cylindrical portions will frictionally engage the cylindrical member and the teeth will engage material to be held.
In testimony whereof I have hereunto set my hand in presence of two witnesses.
