To all whom z' may concern.'

Be it known that LWILLMM H. Douanes, a citizen `of the United States, and resident of Belleville, in the county yof Essex and State of New Jersey, have invented a new and useful improvement in Clamps ,for Wind-Shields, of which thefollowing is a specification. p

rThis invention relates to an improvement in clamps for wind-shields, ,with the` object in view of providing a clamp which will be effective, cheap in construction and easy to manufacture.

Another object is to provide a device whereby the wind-shield may be removed and replaced very readily without disturbing the clamp or stationary portionV of the supporting structure.

A practical embodiment of my invention is represented in the accompanying drawings, in which- Figure 1 represents in detail portions of the wind-shield and roof of an automobile with the device as applied to one side thereof,

liig. 2 represents a transverse sectionV of the same taken in the plane of the line rifof F ig. l,

Fig. 3 represents a detail central longitudinal section on an enlarged scale, taken through the clamp and a portion of the wind-shield frame,

Fig. l represents a central section taken at right angles to F ig. 3, and

Fig. 5 represents a horizontal section taken in the plane of the line B-B of Fig. 3.

The clamp consists of a stationary member and a swinging member. The stationary member comprises a post 3, which may be secured between the usual support, not shown, and the roof 4, for supporting one side of the windshield. This post is shown as provided with a head 6 formed integral therewith and having` a cylindrical socket 7 therethrough forming an exteriorly unbroken wall.

A slot 8 leads from the socket 7 to a point 9, thereby forming walls 10, 11, which are adapted to be drawn toward each other by means of a thumb screw 12`passing freely through the wall 10 and having a screwthreaded engagement with the wall 11. The walls of the slot and socket form an unbroken continuation of the post.

A friction washer 13 may be placed between the wall 10 and the head of the thumb screw `l2.

The swinging member comprises a hub 1% adapted to rotate in .the spcket fr', which hub iS held therein by e plete l5 which @verle-PS the outer face of the head 6 and is secured to the hub by means of a screw bolt 1G. The swinging member is further provided .with a channel 1'? cut therethrough for the recep tion of the frame 18 of the wind-shield glass 19. The frame 18 is secured in the channel 17 by means of ears 20 carried by the frame and screws 21 having a threaded engagement with the swinging member. B v this means of securing the frame of the windshield to the clamp, the shield may be readily removed and replaced without disturbing the clamp or stationary portion of the supporting structure.

By turning the screw 12 inwardlv, the walls 10 and 11 will be drawn toward each other, which will contract the slot and socket and thus firmly clamp the hub therein.

By turning the screw outwardly, the walls 10, 11, will be released and the socket will be free to expand, thereby loosening the hub in the socket, which allows the shield to be.

adjusted to any desired angle.

By forming the walls of the slot and socket in an unbroken continuation of the post, the walls of the socket will be contracted evenly and caused to clamp the hub at all points around the same, as distinguished from those clamps in which the walls are broken either at the socket or the slot, where the clamping pressure will be uneven and therefore not so effective; the turning strain on the hub in one direction tending to diminish the gripping action of one jaw of the clamp and the turning strain in thel other direction tending to diminish the gripping action of the other jaw.

It will be understood that the normal condition of the socket and slot will admit of a free movement of the hub in the socket, so that only a slight movement of the screw is necessary to tirmly clamp or release the hub.

It is evident that slight changes might be resorted to in the form, construction and arrangement of the several parts without departing from the spirit and scope of my invention; hence I do not wish to limit myself strictly to the structure herein set forth, but

from one side'of the socket into the post, the

Walls ot' the socket and slot forming an unbroken continuation of the post, a hub rotatable in said socket, and means interposed between the socket and the end of the slot for uniformly contracting said socket and slot Jfor clamping thehub against movement. 1 2. In a wind-shield, a post havinga cylindrical socket and a longitudinal slot leading from one side of the soeket into the post, the walls of the socket and slot forming' an unbroken continuation of the post, a hub rotatable in said socket, a framecarried 'by said hub, means for removably securing said frame directly to the hub, and means interposed between the socket and the end of the slot for uniformly contracting the Copes'of this patent may be obtained for socket and slot for clamping the hub against movement. o i

3. In a Wind-shield, a post provided VWith a head having therein a cylindrical socket and a slot leading therefrominto the post,

the Walls of the socket and Slot forming an unbroken continuation of the post, a` hub rotatable in said socket, "a frame having'YY ears, means for removably securing said ears toV the hub, and means for contracting said slot andl socket for clamping the hub againstl movement.
