To allwkomt'tmay concern: j 7

Be it known thatv I, GREENE O. Hoscn, a citizen of the United Statesyresidinginihe city of StLouis and State'ofMissouri, have invented new and useful Improvements in swiveling Supports, oi which the following is a specification. 7

This invent on relates to a swiveling support. While the device is intended, tonbe 10 especially useful as'a supportfor avcounter accessory, such as a measuring machine, it may also be used to provide a swiveling support for a machine or device for any purpose;

The general produce a swiveling support of very simple construction which is soconstructed as to enable the device which it supports to' rotate about an axis and which will operate in such a way as to holdthe device substantially fixed in a plurality of different positions; this result is accomplished bymeans operating automatically, that is to'saycby means whichwill operatesimply by the ro-- tation or swiveling movement without-necessitating the direct manual-operation of 'any locking member. v Further'objects of the inventionwilljappear hereinafter.

The invention conslsts in the generalcombination of parts set forth in the appended claims, anddescribed in the following specification, all of which contribute to produce a simple and eflicient swiveling support In the drawing'which fullyillustrates the preferredtembodiment of my invention,

Any

injgly against "rotation but-which will-per- I be a d i a SuffiQie itIrota'Qive 1 force be applied to it. .Thi i accomplished by providing oneof'these' members with a 7 plurality-=of recesses disposedcircumferen tRI-llYQJIIOUIICl the axis of'rotation'andpro- V Y rotation, but will be disengaged automati I V cally by the rotary, or swivel-movement.

In order to accomplish this and givefthe I structure rigidity, the rotary memberv is pivotally mounted on a central stud 4, hava tubular housing 7' which is' formed in-V tegral with a bracket member 6.. i

. The bracket member 6 may be'fin the of" a central post, having an elongated shoe 6 integral with it at'its lower portion, and this shoe may bepprovided with suitable means forguiding it along the counter. For '7 this purpose I provide a plate 8 carrying. rollers or wheels 10 mounted on large pins ure 3.) These wheels 10 operateas means for guiding the bracket member along a suitable track attached to the counter. The. stud inlay be held in place by suitspring-washer 20 which seats able nuts l2 mounted on its lower end, which seat against a washer 13 which lies against the lower end of the tubular housing 7.

I also provide means for yieldingly pressing the rotary member against the bracket member. F or this purpose I prefer to provide the upper end of the bracket member 6 witlia wear-plate 14 and on this wearplate 14, there seats a corresponding wearplate 15 carried by the underside of the rotary member 1. The rotarymember is pref erably formed with a chamber 1 on its upper side, and in the bottom of this chamber, I secure socket means in the form of a socket-plate 16 which is secured to the rotary member by suitable screws 16*. Seating on the socket-plate 16, I provide detent meansl'l in'the 'form of a collar which is secured to the stud 1 by means of a pin 18, said pin passing into a diametrically placed opening ofthe stud, through a vertical elongated slot 19 in the side of the collar. By

reason of this slot it will be evident that an upward movement of the collar 17 on the 'studwill be permitted. The means for actuallypressing the rotary member 1 yieldingly against the bracket member 6, consists of a on the upper face of the collar 17, the same being held in place by a nut 21 which screws onto threads adjacent to the end of the stud. The socket plate 16 is provided with a plurality of" circuinfer'en'tially disposed recesses which are in the form of radially disposed grooves 22. With these grooves 22, a projection 23 on the underside of the collar 17 co-operates.

Normally the projection 23 engages one of these grooves 22, or two diametrically opposite grooves in case the projection 23 lies on both sides of the axis of the collar 17, as in Figure 5. This holds or detains the rotary member against rotation; However,

when it is desired to rotate the rotary mem- "ber in its swiveling movement so as to hold it in a different position, it is simply necessary to rotate it forcibly. This rotation causes the socket-plate 16 to rotate under the collar 17 so that the projection 23 rides up on to the surface of the plate between the recesses. The yielding means 20 operates to yield, and this upward movement of the collar is permitted by the slot 19. The rotation is continued until the projection 23 comes opposite the next adjacent recesses whereupon the vielding means or spring-washer 20 will "force the collar down and cause the projection 23 to engage the recesses, in this way locking or detaining the rotary member in a new position; in this way the recesses and the projection cooperate to hold the rotary head in a plurality of different positions.

Although I have illustrated only four of the recesses 22, which is all that would be required for the service stated, obviously there may be as many of these recesses as desired,

where advisable, to adapt the device to special purposes. In the present instance it has only been considered necessary to provide for holding the swiveling head in four different positions.

It is understood that the embodiment of the invention described above is only one of the embodiments my invention may take and I do not wish to be limited in the practice of the invention, nor in my claims to the particular embodiment set forth.

What I claim and desire to secure by Letters Patent is 1. In a swiveling support, the combination of a relatively fixed bracket member having a post, a. swivel-head supported on the upper end of the post, a pivot stud connecting the swivel-head and the post and rigidly secured to the post, a socket-plateattached to theswivel-head and having a plurality of recesses on the face thereof circuin-' stud so as to rotate therewith andcapa-bleof a movementlongitudinally on the stud,

said collar having a projection seatin'g'o'n the said socket-plate to engage wit-h any of the recesses to hold the rotary head against rotation, and aspring carried on the stud to force the collar against the socket-plate and permitting the collar to move away from the socket-plate when said head is given a swiveling movement. 1

2. In a swiveling support, the: combination of a relatively fixed bracket member having a post, a swivel-head supported on the upper end of the post, having a chamber on its upper side, a pivot studconnecting the swivel-head and the post and rigidly secured to the post, a socket plate attached to the swivel-head in the bottom of said chamher and having a plurality of recesses on the face thereof circumferentially disposed about the axis of said stud, a collar on said stud connected to the stud so as to rotate therewith and capable of a limited upward movement on the stud, said. collar having a projection seating on said socket-plate to engage with any of said recesses to hold said rotary head against rotation, and a. spring. above the collar andiorclng the same down 7 to the swivel-head in the bottom of'said chamber and having a plurality of recesses on the face thereof circumferentially disposed about the axis of said stud, a collar on said stud connected to the stud so as to lar to move upwardly when said head is rotate therewith and capable of a limited upgiven a swiveling movement, and means 'carward movement on the stud, said collar havried on the upper face of the head for securing a projection seating on said socket-plate ing a counter accessory to theswivel head. I
