WIND SHIELD.

Application filed August 23, 1926. Serial No. 13 1,008.

This invention relatesgenerally to wind- .shieldsand more partlcularly. torwindshield operating mechanism.

Ode of the ob'ects of this invention is to provice an operating mechanism for wind-.

4 shields involving a unitary self-locking control ,and'further mechanism of this char- ;acter which is distinguished by its simplicity thereby enabling the same to be manufactured at a-minimum cost and assembled with facility. v

Another object of this invention is to pro vide amechanism of this character which is inherently resilient so that shocks or jars occasioned to the windshield or to the frame are dissipated or minimized.

' tional viewthrough a windshield construction constructed in accordanceivith this invention.

Figure 2 is a vertical transverse sectional view indicated by line 22 in Figure 1, and Figure 3 is, a longitudinal vertical section taken substantially onthe plane indicated {by line 3- in Figure 2.

Referring now particularly to. the drawings wherein like reference characters inclicaselike parts, it will be noted t-hat there is herein illustrated a windshield providing ;upper and lower sections and 11 the lower section being swingingly mountedad- 'jacent its upperedge on horizontally disposed pivots 12 carried-by upright'frame members 13. The. lower isash '14 of the windshield 11 is formed ,with a longitudinally extending recess or pocket15 in the lower edge thereof which, cooperates with a weather strip 16 arranged in a rabbet formed inthe upper face of the frame The operating mechanism for swinging thawindshield about its pivots l2includes a housingindicated generally by the reference character 18 this housing being secured to the frame base 17 by means of laterally extending flanges 19 and securing screws 20 The tubular portion 21 of the housing is open at both ends and extending longitudi nally Itherethrough is aishaftpor rod #22 to one end of which a'handlef23 is secured. This handle is formed with a centrally arranged boss 24 which fits within the end of the tubular portion 21 of the housing and has a bearing engagement'therewith. The

other end ofthe shaft 22 isvsecured to a bearing plug25 by means of a pin 26,fl.this plugbeing form-ed witha'boss or 'extension 27 projecting into the housing and having a bearing engagement therewith.

Associated .with the shaft 22for rotation therewith is a spiral member 28 preferably formed of resilient materiahit being found that a coil spring may be employed in this connection with entire satisfaction. I The spiralmember 28 surrounds the shaft 22 and has one end anchored in a recessformed in the hub of the handle as indicatedoat 2 9 and the other end anchored in a recess formed in the boss 27 of-the; plug 25iasindicatedat 30. The diameter of, the convolutions of this spiral member is such that a clearance is providedfbetweenthese. convolutions and the shaft 22, a

The reference characters 31 indicates., generallya runner or carrier, which is movable longitudinally of the housing 18.. This runner is provided with a cylindricalor tubular portion 32 which surrounds shaft 22, this runner extending upwardly A from the shaft through a slot 33 formed ,in the tubular portion 21 of the housing. {The runner is formed with a pair of spacedlportions or cars 34: which receive therebetween oneend of a link 35 this linkbeing pivoted. to, these bracket 38 secured asat 39,:to. thesashl i of the ,windshield. Y 1

The tubular portion 32 of the runner 31 is extended in the longitudinal .direction of 1 theshaft22so as to forma-relatively long portion for engagement with this ,shaft whereupon. a foreand aft, rocking movement ,of the carrieror runner ispreventedand this element properly guided. in v. its smovement longitudinally of the housing. Any lateral rocking movement of the runner is prevented by means. of. ribs .40 projecting. laterally therefrom which engage the edges of the slot 33.

The runner or carrier is provided With an aperture 41 extending laterall therethrough and through which the spira element 28 is ears by means of a pivot pin:36. Theother end of this linlrispivotedas at.37 to a.

- threaded. As a consequence of this con struction when the handle 23 is rotated the shaft-22 and spiral element 28 will be l1ke wiseirotated and because of the engagement 5 between this latter element and the runner V element 23 of resilient material as for instance by using a coil spring, shocks or ars ing claims.

imparted directly to the windshield or to the frame will be absorbed or dissipated so that these shocks, which in some instances prove disastrous to the windshield, are sufliciently minimized to be of no consequence.

The structural characteristics of the device permit the same to be manufactured economically and quickly and easily assembled.

While the device is illustrated herein as applied to the lower section of a double section windshield it will be readily apparent that this operating mechanism will function i with equal facility in connection with a single panel windshield and may also be em ployed in connection with Windshields swinging .both inwardly and outwardly with reference to the frame. As consequence reservation is made to make such changes and modifications in the invention as may come within the purview of the accompany- WVhat I claim as my invention is:

1. In combination, aswinging windshield, a rectilinearly movable carrier, means for connecting said carrier to said windshield for adjusting the latter and means for actuating said carrier including a spiral resilient element connected therewith.

2. In combination, a swinging windshield, a rectilinearly movable carrier, means for connecting said carrier to said windshield for adjusting the latter, means for actuating said carrier including a spiral resilient element, means for rotatively mounting said element and means for rotating said ele ment.

3. In a windshield construction, a swinging windshield, a housing, a shaft therein, a runner guidingly supported by said housing and shaft for movement longitudinally thereof, a rotatable spiral member for moving said runner and means connecting said runner to said windshield for adjusting the latter.

4. In a windshield construction, a swing-- ing windshield, a housing, a shaft therein, a runner guidingly supported by said housing and shaft for movement longitudinally thereof, a rotatable resilient spiral member for moving said runner and means connecting said runner to said windshield for adj usting the latter.

5. In a windshield construction, a swinging windshield, a housing, a shaft therein, a runner guidingly supported bysaid housing and shaft for movement longitudinally thereof, a spiral spring associated with said shaft for rotation therewith and engaging said runner for moving the same and means connecting said runner to said windshield for adjusting the latter. 7

6. In a windshield construction, a swingingly mounted windshield, a rotatable coil spring, a carrier movable thereby and means connecting said carrier and windshield.

7 In a windshield construction, a swinging windshield, a housing having a longitudinally extending slot therein, a shaft positioned within said housing, a runner guidingly supported upon said shaft and havmg an upstanding portion extending through said slot permitting a longitudinal move ment thereof, a rotatable spiral member for moving said runner and means connecting the upstanding portion of said runner to said windshield for adjusting the latter.

8. In combination, a swinging windshield, shield, a rectilinearly movable carrier, a rotatable spiral element extending'through a lateral opening in said carrier for moving the latter and means connecting said carrier to said windshield for adjusting'the latter.

9. In a windshield construction, a swinging windshield, a housing, a shaft therein, a runner guidingly supported by said housing and shaft for movement longitudinally thereof, a rotatable spiral element surroundmg said shaft in spaced relation thereto for moving said runner, and means connecting said runner to said windshield for adjust ing the latter. I

10. In a windshield construction, a swing ingly mounted windshield, a shaft, a rotatable spiral element surrounding said shaft in spaced relation thereto, a runner having a portion interposed between said shaft and spiral element and rectilinearly movable by the latter along the shaft and means connecting said windshield and runner for ad justing the former.

In testimony whereof I affix my si nature.
