HINGE.

instance in connection .vith windows o-rwind' shieldsof automobiles. In hinges of this nature there are usually two relatively movable members having frictional engagement together with suitable stop or catch mechanism adapted to normally hold the members -in anyone of a plurality of resting posi- 'Y 2g tions.

My .invention is designed more particu- I\` larly to reduce the friction between the relatively movable members, thus to decrease the actual power necessary in shifting the device from one resting position to another, While at the same time retaining a great pressure between the two members so as to secure an efficient lock for the members in any one of their resting positions.

provide a ball bearing structure in connection with the two rotatable members so as to keep them separated, and then provide additional, preferably spherical, elements which control the holding of the members in any one of their predetermined resting positions.

I Will explain one form which my invention may take more in detail by referring to the accompanying drawing in which;

Figure 1 shows a wind shield equipped with my improved hinge; Fig. 2 is a side view thereof, the window being in section; Fig. 3 is a transverse sectional View of my improved hinge; Fig. 4 is a sectional view on line a-'L of Fig. 3; Fig. 5 is a side View of one of the relatively rotatable members Fig. '6 is a side view of the other rotatable member, and Fig. 7 is a partial sectional View on line'b of Fig. 4.

Referring to Fig. 1, I show a casing 1 having a Window 2 which is adapted to be held in any given position through the agency of my improved hinge 3.

My improved device consists of two relatively rotatable members ,respectively the Specification of Letters Patent.

member 4 and the member 5. These members, as clear, are fastened respectively to the window and the casing.` VThe element 4 has a ball race and the element 5 has a ball race 7, which ball races are placed in juXtaposition and accommodate balls S all as is more clear from Fig 3.

In Figs. 5 and 6 ridges 9 and 10 are shown on the opposite sides .of which the

ball races

6 and 7 are to be found. The balls of course keep the face plate portions 11 and 12 respectively of the

elements

4 and 5 separated a slight distance so that the relative rotationbetween these two members 4 and '5 occurs through the inter-position of the balls 8. The two face plate portions of the elements are placed in juxtaposition as shown in Fig. 3 and are held tightly together by a spring 13, which spring has its tension controlled by the screw 14 and the nut 20. The screw 14 has a preferably triangular head as shown so that it fits in the depressed portion 15 of a face plate 16, which face plate is arranged on the outside of the element 4 as readily apparent. The screw passes through the central openings 17 and 1S respectively of the

elements

4 and 5 and also passes through a cap 19 seen more clearly in Fig. 3. The nut '20 has a cotter pin 21 passing through the Same and the screw 14 so as to prevent dis- The member 5 has projecti'ng

pins

22, 22 which fit in recesses 23 provided in the cap 19. The spring 13 as is apparent is interposed between the face plate portion 12 of the member 5 and the cap 19.

The cap 19 has a plurality of recesses 24, which recesses accommodate springs 25, which springs impinge against the balls` 2o. These balls 2G lare carried within apertures 27 provided in the face plate-portion l2 of the member 5. Irotruding portions of thesi` balls rest in recesses 2S provided in the face plate 11 of the member 4.

:It will be noted that the recesses 28 are smaller in diameter than the diameter of the balls 2G so that the balls-are pressed against the edges of these recesses by the springs 25. As the

members

4 and 5 are relatively rotated about the screw 14, the balls 26 pass from one recess 2S to the succeeding recess 28 and theface plate, portions of the members are kept in their proper positions by the spring 13, the balls 8 providing a` suitable ball bearing between these two

members

4 and 5 as they are being rotated. From this it will be readily seen that the spring 13 so that any wear between the

members

4 and 5 is readily compensated for and taken-up and there is provided at all times a solid piece of apparatus. The springs 25 areof course of such strength as to maintain the members in any one of their predetermined resting pgsitions in which the balls 26 find lodgment lagainst the edges of the recesses 28. The tapered portion of the screw head 14 Within the tapered aperture provided within the stemV 16 also assists materially inkeeping the parts ,alined and tightly together. It will be seen that the

members

4 and 5 are-readily made of punchings and thus lend themselves t Tai very moderate priced construction.

From what has been described the nature of my invention will be readily .clear to those skilled in the art,and it will also be clear that modifications within the' scope of the appended claims can be readily made without departing from its spirit.

Having however thus described one form which my invention may take, what I claim as new and desire to secure by Letters Pat ent'is:

1. In a device of the character described the combination with a pair of relatively rotatable members, means for pressing said members toward each other, a ball bearing interposed between said members, and spring controlled detents in combination with means to hold said members in any one of a plurality of resting positions.

2. In a device of the character described the combination with a .pair of relatively rotatable members, means including a cap for pressing said members toward each other, a ball bearing interposed between said members, and spring controlled detents in combination with means to hold said members in any one of a plurality of resting positions.

3. In a device of the character described the combination with a pair of relatively rotatable members, means including a cap for pressing said members toward each other, a ball bearing interposed between said members, spring controlled detents in combination with means to hold said members in' any one of a plurality of resting positions', and springs for controlling said detents abutting said cap.

4. In a device of the character described the combination with a pair of relatively rotatable members, means for pressing said members toward each other, said means in-y cluding a vbevel headed screw, and one of said members having a beveled face to c0- operate with the beveled head of said screw,

.a ball bearing interposed between said members, and spring controlled detents in combination with means tohold said members in any one of a plurality of resting positions.

5. In a device of the characterdescribed the combination with a pair of relatively rotatable members, means including a cap for pressing said members toward each other, a-

- a circumferential ball bearing interposed between lsaid members close to the axis of rotation of said members, spring controlled detents in combination with means to hold said members in any one of a plurality of resting positions, a spring for controlling sai d detents abutting said cap and abutting one of said members substantially 'at said ball bearing, and means for preventing relative movement betweensaid cap and one of said members.

In witness whereof, I hereunto subscribe my name this 17th day of February, A. D., 1915.
