WINDSHIELD ATTAGHIEENT.

T 0 all whom it may concern:

Be it known that we JOSEPH H. Vrrmnnns, JOHN HALLIDAY, and Josnrr-r PRESNER, all subjects of the King of Great Britain, and residents of the city of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Windshield Attachments; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates particularly to attachments of the type disclosed in a pending application Serial No. 443,466 for shielding the eyes of the occupants of motor vehicles from the suns rays and for protect ing the wind shield glass particularly the upper section of the latter from rain, snow or sleet.

he object of the present invention is to provide an attachment of this nature possessing increased efficiency and greater durability and which can be manufactured at a comparatively low cost.

To this end our invention consists of the construction, combination and particular arrangement of the parts hereinafter described and illustrated and pointed out in the claims.

The accompanying drawing illustrates the preferred embodiment of our invention which consists of a tubular casing 2 having a longitudinal opening3 and closed ends 42 and 5. This casing contains an all-metal roller 6 which is j ournalled in the ends 1 and 5 respectively, the roller having wound there on a blind 7 which is adapted to be extended outwardly through the opening in the cue ing. Means for extending the blind comprises a pair of lever arms 8 and 9 one of which is pivotally mounted upon each end of the casing 2 with the front ends of the arms in operative engagement with a reinforcement device 10 upon the front edge of the blind and adapted to swing outwardly from a position substantially parallel to the casing to a position oblique thereto the lat ter position being determined by the size of the blind.

This reinforcement device preferably con. sists of a sheet-metal member bent to sub stantially U-form in cross-section to present a channel 12 into which the said front end of each lever arm projects. The latter is of angular cross-section between its ends and is so disposed that one flange is adapted to operate within the channel 12 such flange lying within the channel substantially throughout its length when the blind is in the withdrawn position. The outer end of such flange is of increased width and presents a curved bearing surface 13 the curve being sufficiently wide to prevent undue wear on the reinforcement member 10. The opposite end of each arm is forked as at 1 1 to effect its pivotal connection to the adjacent end of the casing and it is provided with a tail 15 which is operatively connected to the corresponding tail on the other arm by springs 16 and 17 the springs imparting to the arms a tendency to swing outwardly relatively to the casing for the purpose of yieldingly maintaining the blind in extended position. This construction and arrangement of parts also maintain the front ends of the arms in bearing relation with the reinforcement member 10 without the aid of means for fastening the reinforcement member and arms together thereby providing a more durable, cheaper and more eflicient construction than is obtainable if additional means for securing each arm to the reinforcement "to be fitted within the ends of the tube and provided with preferably three lugs or clips 21 which are sprung over the ad acent end of the tube, the clips belng of su'ilicient depth to present a shallow socket 22 ateach end of the roller'into which a hub or boss 23 projects,this boss being formed mtegrally with each of the casing ends 4 and 5 respectively. The closure 19 rigidly carries a trunnion 24 which is journalledin the adjacent boss. The'mount for the roller at its opposite end is effected by a comparatively short shaft 25 disposed longitudinally within the roller tube and having its inner end rotatably mounted in a block 26 rigidly secured within the tube. The outer end of the shaft projects through acentral opening 27 in the disc 20 and is flattened as at 28 and inserted into a slot in the ad acent boss on the casing end, the shaft being thus held against rotation but permitting rotation of the-roller. A connection between the two is efiectcd through a helical spring'29 which encircles the shaft throughout its length and has its inner end secured in a slot or opening'SO in such shaft its opposite end 31 projecting through a hole 32in the disc 20.

As hereinbefore stated, the size of the blind determines the extent of its projection, that is to say, it is extended untilcompletely unwound from the roller. It is obvious, therefore, that the connection of the inner end of theblind to the roller must be such that such inner end will not be subjected to undue wear" and tear when the fluid is extended. To provide such a connection which will also enable the blind to be read ily detached from the roller the tube 6 is provided with a longitudinal opening 33 extending throughout its length and the edges thereof are bent back as at 34 and 35 for reinforcement purposes. The blind is adapted to be projected through this opening and its inner end is sewn around a rod 36 located within the roller and extending throughout the length of the same and of a diameter larger than the width of the opening for prevent-in complete displacement from the roller. Each end of the rod is provided with an eye-36 and the blind is stretched thereon'and secured thereto at its ends by wire fastenings which are threaded through such eyes thereby preventing wrinkling in service. In order to ensure uniform winding of the blind on the roller tended position.

acting a pawl preventing such rotation.

This may be employed at opposite ends of the roller if it'is desiredto have a closure for such end detachable, one enfdhowever only need be detachable to permit insertion of the rod 36 into the roller. It may be found desirable to employ blocks similar to the block 26 spaced throughout the length of the tube 6 for the purpose of reinforcement.

The block 26" is cut away as at 41 to accommodate the rod 36. The outer end of the blind is secured to the reinforcement bar 10 the connection being efl'ectedby carrying the" blind over the front edge of the bar and beneath the same where it is secured in a relatively small tube 43 formed by bending the adjacent edge of the bar to cylindrical form, the blind being secured in the tube by rod 44 which is sewn into theblind and its ends being secured to the ends of the blind ina similar manner to rod 36. The

endwise the longitudinal opening 45 being provided to accommodate the blind.

In order to withdrawthe blinda wirecord 46 is secured to the underside of the bar 10 is passed through a lock 47 mounted on the casing 2 to a point in the vehicle withinreach of the driver whereby the latter by a pull on the cord maywithdraw the blind when desired. The I lock 47 which maintains the blind in the'withdrawn position consists of a unitary member 48 having a tapered opening 49 through which the cord passes. Positioned centrally of the mouth of the larger end of such opening is a movable jaw 50 actuated by a spring51. This jaw has concave faces 52 and 53 and is adapted to engage an enlargement 54 on the cord. The cord may be released trom'the position in which it is locked by the jaw by moving the cord with its enlargement laterally until such enlargement clears the jaws. The springs 16 and 17 are of suflicient strength to overcome the spring 29 so that the blind, unless held in'withdrawn position by the cord 46, will normally assume its eX- The casing 2 is adapted to be secured to the motor vehicle in any preferred manner. In the accompanyin drawing a forked bracket 55 is mounte rod is adapted to be inserted into the tube upon each end of the casing-2 and adjust i ably carries a pair of clamping jaws 56, the adjustment enabling the attachment to be secured to Windshields of varying width.

This adjustment is obtained by slidably mounting the head of a bolt 57 which carries the jaws in the fork of the bracket.
