BUTTON.

Specification of Letters Patent.

Patented Oct, 8, 1907.

Application filed October 27, 1905. Serial No. 284,607.

Y To all whom it may concern:

Be it known that I, FRANK P. PFLEGHAR, a citizen of the United States, and a resident of New Haven,

in the county of New Haven and State oi' Connecticut,

h'ave invented a new and useful Improvement f in Buttons, oi which the following is a specification.

My invention relates to a button and more particularly to a button for holding a vehicle curtain. securely fastened.

In vehicles provided with curtains exposed to great air pressure, for instance, curtains on high speed auto'- mobiles, great difficulty is experienced in holding the curtains securely fastened when lowered for use, and, at the same time, providing for quickly and easily unastening'the. curtain when it is desired to raise it out of use.

My present invention is directed to means for overcoming this ditliculty and consists in a button comprising a stationary hollow stud over which an eye in the curtain is passed, a bolt seated and movable transversely in the said stud and a rotary key and eccentric extending into the stud and engaged with the bolt for projecting the bolt laterally from the stud and withdrawing it.

In the accompanying drawings, Figure 1 is a iront view of a portion of a curtain with the button in locked position, Fig. 2 is a top plan view, Fig. 3 is an enlarged horizontal section in the plane of the line A-A oi Fig. 1, Fig. 4 is an enlarged vertical section in the plane of the' line l3-B of Fig. 1, Fig. 5 is a similar view showing the button in unlocked position, Fig. 6 isa back view of the stud showing the retaining spring in position, Fig. 7 is a similar view with the retaining spring removed and showing the base of thev eccentric in operative position,- Fig. 8 is a rear end view of the key, Fig. 9 is a iront end view of the eccentric, Fig. I0 is a rear view of the locking dog or bolt in detail. Fig. 11 is a side view of the key in detail, and Fig. 12 is a side view of the rotary disk.

The curtain is here represented by 1 and may be of any material such as is commonly used for the purpose.' It is provided with an eye 2 surrounded by a metal gromet 3 for protecting its wall as is common.

The stationary stud which supports the movable parts ofthe button consists oi a base plate 4 from which a hollow neck or barrel 5 extends outwardly for receiving the eye oi. the curtain. Transversely through the neck 5 there extends an opening 6 in which the locking bolt or dog 7 is seated and in which the said bolt or dog has a sliding movement. The bolt or dog 7 has its locking end partially cut away on the inner or rear side to afford an extended flat bearing 8 on the gromet and at the same time to provide for the thickness oi the curtain without unduly lengthening the neck of the stud, and the said bolt has its ends rounded to conform to the curved surface oi the neck 5 of the stud in which it is mounted. The bolt or dog is lurther provided with a transverse slot 9 open to the rear and with a transverse slot l0 open to the front and merging into the slot 9.

The hollow neck 5 oi the stud has mounted therein a rotary disk 11 having a flanged base 12 and an eccentric projection 13 extending into the transverse slot 9 in the bolt when the latter is in position in the stud.

The i'ianged base 12 is provided on its rear face with indentations 14, 15, for the reception of a nose 16 of the retaining spring 17 to hold the eccentric in its positions with the bolt 7 advanced and withdrawn.

The retaining spring 17 is located in a shallow recess 18 in the rear face oi the base 4 Of the stud, the said recess being conveniently undercut at one end to retain the spring and a small screw 19 may be employed.

The eccentric projection 13 is operated by means of a key 20 provided with a central pin 2l which extends rearwardly through the disk which carries the eccentric 13 and has its rear end provided with a nut 21* to hold the key in position. The key 20 is further provided with a pin 22 eccentrically set therein and extending rearwardly into the eccentric projection 13. The key 2O is further preferably centered in the outer end of the neck 5 oi the stud by means of a 'short cylindrical projection 23 on its inner or rear end which fits in a shallow recess 24 inthe outer end of theneck. The maximum diameter of the key 20 is intended to be not materially greater than the maximum diameter of the neck 5 ofthe stud as the eye of the curtain is passed over the key as well as over the stud in securing and releasing the Curtain.

In assembling the parts, the bolt 7 is irst placed in position in the opening 6 in the neck 5 oi the stud with the fiat bearing 8 facing inwardly, the rotary disk 11 then inserted through the base of the stud with its eccentric projection 13 in the recesses 9 and 10 in the bolt and the key then placed in position from the iront of the stud'and its central pin made fast to the disk 11 by the nut 21*. The retaining spring 17 is then placed in position in the shallow recess 1S in the base 4 of the stud and the button as a whole may be secured to a suitable support ior example, the support 25, by means of screws 26, 27, extending through the base 4 and through the opposite ends oi the spring 17 into the support.

In operation, the slot 10 in the bolt permits the eccentric projection 13 to be turned in one direction only by the pin 22, the latter resting against the bottom wall o said slot when the key is turned to its limit in either oi two opposite directions. The nose 16 ofthe retaining spring- 17 will engage the indentation 14 when the eccentric projection 13is at one limit of its rotary movement, for instance, to advance the holt, and the other indentation l5 when the eccentric is at the opposite limit of its rotary movement., ior example, to withdraw the bolt. When the eye oi the curtain llas been passed over the stud and the bolt advanced, no strain on the curtain can exert a pressure on the belt in a direction to release it, as any outward pressure is at right angles to the direction in which the bolt nieves.

This structure also provides for placing the button complete on the support to which the curtain is to he fastened, leaving,T the curtain itseli iree troni any part, or memberol the button and provided simply with an eye.

The structure is neat in appearance, strong and durable and may be manipulated easily and quick y.

What l claim is z- 1. A hntton comprising;- a stationary hollow stnd ior receiving an eye in the curtain, a holt seated in and movable transversely of the stud and a rotary key and eccentric for operating; the holt'.

2. A hntton comprising a hollow stationary sind i'or receivingv an eye in the curtain, a holt seated in and movahle transversely of the stud, an eccentric mounted in the stud and adapted tio be engaged with the holt for operatine it, and a key mounted on the outer end olf the stud and en ;'agg'ed with the eccentric for operating it.

I). A button comprising a hollow Stationary Stud tor receiving' an eye in the curtain. a holt. seated in and mov ahle transversely ot` the stud. an eccentric enI eetl with the holt and removahle only rom the rear t'aee or end ot the stud and a key engaged with the eccentric and re movable only irom the onter end o1' the sind.

4. A button comprisingl a hollow stationary sind provided with a shallow recess in its hase, a holt movable transversely ot.' the sind. a disk provided with an eccelltric projectingl therefrom t'or operating' the holt and a retaining: spring;l engaged with the said disk for retainingl it4 and hence the bolt in the desired position.

5. A. button comprisingV a hollow sind. a holt, seated lr.-tnsversely in the sind and provided with connnnnie.1t inel slots extending transversely through it. an eccentric located in one ol' the slots and a, key havin;I4 r projection extending' through the other slot into cneaeement with the eccentric.

t?. A lnttton comprising' a hollow stnd. a holtV seated trans\ rsely therein and havin; its lot-kine end partially cnt an eccentric tor projectingl the holt, i'rom the .sind and witinlrawine it. and a key 't'or operatingthe eccentric.
