BUTTON CONSTRUCTION Filed Oct. 6, 1934 INVENTOR ABRAHAM H. FEUERSTEIN Patented Dec. 31, 1935 UNITED STATES PATENT OFFICE BUTTON cons'moo'rron' Abraham H. Feuerstein, New York N. Y. Application October 6, 1934, Serial No. 747,120 2 Claims. (c1. 24-9o v This invention relates to new and usefulimprovements in a'button construction.

The invention has for an object the construction of a button which is characterized by a head of non-resilient material and a stem with a solid shank arranged with resilient elements compressible into an opening in said head in such a manner that the shank may be forced into the open ing for the permanent connection of-the stem and head.

The invention may better be understood, by first considering several old constructions and then understanding the structural differences and advantages of this invention. 7 v i It is old to form a button having a head and a stem with a solid shank which is forced into an opening in the head. Such prior construetions' were arranged with non-compressible ele ments upon the shank, and 'the arrangement necessitated that the button head be of resilient material such as vulcanized fiber, leather board, or the like, so that there is a "give in the head when the shank of the stem is forced into position.- 'A button of this type is illustrated and describedin -U. S. Patent No.-l,318,235. The shortcoming of a button of thistype is the limitation, that the head, be of resilient material." Consequently,it is impossible to construct a but- ,ton in which, for example, the head is pearl v, or imitation pearl, since obviously these materials are not resilient materials, and the engagement of the shank into the opening would be impossible.

- According to this invention it is proposed to arrange elements upon the solid shank of the stem of a button, which elements are in the form of thin ridges or similar constructions, adapted to be compressed into an opening in anon-compressible button head, such as a button head constructed of fresh water or ocean pearl or imitation pearl.

A still further object of this invention is to arrange the ridges annularly and circumferentially, simulating threads, but in which the threads have compressible sections.

Another one of the objects of this invention is to arrange the stem from adjacent stem sections with the contacting faces concaved and formed with -grooves in such a manner to permit compression of the shank when the stem is forced into an opening in the button head.

Still further, the invention proposes the construction of an article of the class described which is simple and durable and which can be manufactured and sold at a reasonable cost.

For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to the following description and accompanyingv drawing, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawing forming a ma terial part of this invention:-

Fig. 8 is'a bottom elevational view of the jaw portion of the device shown in Fig. 7 looking in the directionof the line of Fig. 7.

Fig. 9 is a horizontal sectional view taken on the line 9-9 of Fig. 7.

The button construction, according to this invention, comprises a head ll of non-resilient, material, such as pearl or imitation pearl, or other materials, which is formed with a central opening II and which is associated with a stem. I2. 35, v The stem I2 is formed with a shank I 3 which engages into the opening H. The shank II is solid and is forced into the opening II and isformed; with a plurality of ridges it which are slightly compressible to facilitate engagement of the shank into the opening, and for producing strainsor pressures to hold the stem in position.

More particularly, the stem it of the button comprises a strip of material which is bent at the center with its ends adjacent, and, formed with an opening I! at the bent end through which the button may be attached as desired. The adjacent ends are in intimate contact with each other and the outer sides thereof are formed with the ridges ll. These-ridges ll simulate threads, except for the fact that they extend around the sides of the shank sections and terminate before the adjacent edges thereof. This is clearly shown in Fig. 3. The diameter of the opening II should be slightlysmallerthan the 56.

outside diameter of the ridges H, but should be slightly larger than the root diameter of the ridges. Consequently, the stem may be forced into the opening, and the ridges will become bent against the wall of the opening and grip the wall for maintaining the stem in position.

In Figs. 5 and 6 another embodiment of the invention has been disclosed wherein additional provision is made to provide for the compressibility of the shank of the stem. More particularly, the adjacent faces of the stem sections are formed with grooves, comprising transverse groove portions i6 and lateral groove portions li These groove portions are connected with each other. The arrangement is such that the shank is slightly compressible sidewise and front and rearwise, because of the interior grooves l6- and li Therefore, in addition to the compressibility of the ridges H, the shank may be forced into and maintain its position in the opening in the button head with the resiliency produced by the interior grooves.

In Figs. 7-9 inclusive a mechanism is illustrated by which the stem and button head may be connected with each other. This mechanism comprises a stationary frame 20 having a recessed portion 2| into which a button head l0 may be engaged. This recessed portion 2i is immediately over a stem 22 formed with a lateral recess 23 adapted to receive the button stem in such a manner that the bent portion thereof is engaged'in a receiving recess, and the shank portion of the button stem extends downwards. This shank portion is in alignment with the opening il in the button head. The stem 22 extends into a cylinder 24. The inner end of the stem 22 has a head 25 working in an opening in the cylinder. A spring 26 is arranged in a cavity in the cylinder and acts between the head 25 and the cylinder for normally urging the stem 22 inwards. A pair of pins 21 are mounted upon portions of the frame 20 and extend through openings in the head 24' of the cylinder and are engageable against the stem head 25. A small projection 28 from the cylinder head 22 is adapted to engage the stem head 25 as hereinafter explained.

The cylinder head 24 connects with a shank 28 connected with a ring 29 pivotally mounted intermediate the end of the lever 30. This lever is pivotally mounted at one end 3| on the frame 20. The other end of the lever 30 connects with a rod 32 which connects intermediate the ends of a foot pedal 33. The'foot pedal 33 is pivotally mounted at one end 34. An expansion spring 35 normally urges the free ends of the foot pedal 33 upwards.

The operation of engaging a stem on a button head consists in first placing the button head upon the receiving recess 2i, then engaging the button stem into the receiving recess 23 of the stem 22 as previously explained. Then the free end of the foot pedal 33 is depressed by the operator stepping thereon. Downward motion of the foot pedal 33 moves the rod 32, the lever 30, the ring 23, and the shank 23 downwards. Downward motion of the shank moves the cylinder 25 downwards while the stem 22 maintains a stationary position because of expansion of the spring 25. Downward motion of the cylinder 25, therefore covers the recess 23 and so the button stem is tightly held in position. Further downward motion of the cylinder 24 causes the projection 23 to engage the stem head 25, and thereafter the stem head also moves downwards so that the shank of the button stem is forced into the opening ll of the button head.

When the foot pedal 31 is released the spring 35 will return it to the initial position and the parts of the device which have been moved from their initial position, will return.

While I have illustrated and described the 2 preferred embodiment of my invention, it is to A be understood that I do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as 30 defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:-

1. A button construction, comprising a button 35 head of non-resilient material with an opening on its backside, and a stem with a shank for being forced into said opening and formed with a ridge and groove of spiral shape forced into the opening for engaging the sides thereof under 40 pressure to hold the stem in position, said shank comprising a pair of shank sections adjacent each other, the contacting faces of said shank sections being formed with grooves having lateral and transverse portions.

2. In a button construction, a stem consisting of an eye and a shank, said shank being axially split and having upon its outer periphery a ridge and a groove-of spiral shape substantially in the form of a thread, a button head of nonresilient 5o by the lateral compression forces of said shank when pressed into said opening.
