TRAVELER SLIDE FOR ysArL nrracniuiin'rs.

' VApplication iled May 24,

This inventionrelates to improvements inA securing devices of the type wherein the element or part secured therebyv is restrained for 1 traveling ymovement along a lcertain course,- vand more particularly insome of its aspects the invention crelates to improvements in v ltraveling slides or runners for securing sails Y or'the like kfor traveling movement along a spar or mast. Y l i It is a general object vof the invention `to provide 'an improved securing device of the class mentioned so constructed Vand arranged Y as'to diminish or practically avoid jamming or binding, or similar resistance to free travcling movement ofthe ,securedI element.

Avfurther and vmore particular object is to` provide, in a sail securing device of the class mentioned,.a runner ory traveler slide having Y anv improved anti-friction vattachment whereby jamming with the supporting guideway, or other-objectionable resistance to 'movement'thereof, is` effectively avoided duringy movement ofthe runner. in either direction along the guideway, andunder torsional and other stresses exerted thereon by the sailin A further object is to providea sail securing device of the class mentioned .having an 5 improved anti-friction attaching: arrangelessen the time and veffort required to raise'orV V part obvious in connection therewith.

The Ainvention accordingly comprises the features of'construction, combination of cleinents, and arrangement of parts, which will Y be exemplified in the construction` hereinafter set forth and the scope of the application of which will be indicated in the claims.

Fora more complete understanding of they nature and objects of the invention, reference is had to the following detailed descrip.- tion of the illustrativeembodiment, 'and "to the accompanying drawings, in which y Fig. l is a fragmentary elevation showing Y a sail secured to a kmast by means of the iinproved; attachment.'

" The service'to which travelerslidesgein-" ployed in securing sails to masts,.orfth"e alike,

vin sailing vessels, is eXceptionally rigorous, and the tendency to binding and similar obstruction to free` movement along the 'supporting guideway is particularly great, `due to the. great variety `of torsional stresses eX- i. .erted upon the slide in many vdifferent directions when the sail occupies .different positions relatively to thermast. l This'jbinding tendency is accentuated' bythe jerkingfand guiding attachment thereto remains insta- `slatting action'in raising orlloweringf the fu? i sails under Trough wea-ther conditions. *It

will be obvious that, while the vvmast rand'slidey 75 tionary positiomthesailand attaching con- I nections therefor may be positioned at a great variety of angles tothe mast, and consev quently stresses upon the slide will be exerted in numerous different directions in varying ous' service mentioned. i

Referring to the drawing for a detailed disclosure of theembodimenty of the'invention there shown, a sail l0" of vasailingvessel is supported by a spar or mast 11 which may;

be positionedas desired. lA vguideway 12 in the form-.of an elongatedflatbar or plate is secured' to the mast by suitable securing devices 13, its direction oflength corresponding generally with that ofthe mast. A supporting block or strip lil-may be interposed between the guide bar and thel mast so as to providea.V firm seat for the bar `and tospace. "i

' itslightly vfrointhe'adjacent surface/of the v Y' ioof A pl-urality'of traveler slides or runners 15 Y are mounted for Vslida-bl'e engagement withv rIhe g improved 4traveler Y vslide herein described is design-edv to avoid, `in ya very largedegree, the b-inding resistance v to free movement of the slide'under the rigorthe guideway in-connected relationftherei' with, each runner beingprovided with van at- "taching'ban 16k securedA at longitudinally spaced parts thereof to the runner asby studs 17. The attaching bar lextends longitudinal- 'ly of the runner and is spaced slightly therefrom so as to provide an elongated slot or `passageway for the reception of an attachdescription of all. As shown in Figs. 2 and 3,

the runner is generally channel-shaped in cross section, including a back section 20,'op-

.posed side or edge sections 21 and opposed inwardly extending marginal projections or flanges 22. This construction provides opposed edge channels or grooves 23 for the reception of the edges of the guide bar, as shown inFig; 4. The slide or runner is thus connected to the guide way for traveling movement in either direction therealong.

Anti-friction rollers 24 are mounted upon the runner, there preferably being two of these rollers at each side of the runner, spaced apart longitudinally a short distance. These rollers are positioned for engagement with the longitudinal edges of the guide bar 12, which is preferably provided with rounded corners for presenting smooth contact surfaces with the anti-friction rollers. rl`hese rollers are` preferably positioned wholly within the channels 23 of the runner and their axes are disposed transversely of the channels and of the runner itself.

The contact faces of the rollers 24 may be formed in Wide open channels substantially as shown in Fig. 4 and curved transversely of the contact edges of the guide bar; that is, the concave contact surfaces of the roller are presented to the guide bar edges. The sides of the rollers adjacent the bar edges are preferably disposed within the channels 23 so that the bar edges when in operative position may extend for a short distance into the runner channels 23.

By virtue ofthe open channel construction of the anti-friction rollers with the concave contact surfaces arranged as described, a certain amount of twisting movement of the runner is permitted before the guide bar edges come into contact with the respective roller surfaces. Torsional stresses upon the runner exerted by the sail are thus compensated andthe runner permitted to assume a nonbinding position with reference to the guide bar no matter in what angular direction the pull of the sail is exerted upon the runner. It will be observed that the attaching bar 16 is positioned Aintermediate the pairs of laterally disposed anti-friction rollers so that the tor sional as well as other stresses imposed by the sail in different positions will be equally distribut-ed to the runner, and through the rollers to the guide bar. By means of the arrangement described friction and binding tendency are reduced to a negligible amount. It will be observed that the curvature or concave construction of the open channel contact i surface of the rollers is so proportioned with reference to the width of vguide bar 12 that the bar edges Will contact with said Vsurfaces toward the ends Vof the rollers to limit the twisting or torsional movement of the runner upon its longitudinal axis. The rollers, therefore, always contact with the guide bar in all possible positions of the runner, and at no time is the guide bar permitted to come into contact with the Walls of the channels 23.

.The tendency to binding of the runner is still further diminished by the lost motion or automatic longitudinally adjusting connection between the sail and the runner pro-.

vided by the elongated attaching bar 16, along which the connecting ring 18 is movable. By

means of this adjusting connection longitudi- Y nal pulls upon the runner Will always be exerted at theforward end thereof, thus helping to keep the runner in correct alignment with reference to the guide bar.

Since certain changes may be made in thel scope of the invention which, as a matter of language, might be said to fall therebetween.'

Having described my invention, what I claim as new and desire toV secure by Letters Patent, is: i

1. In a device ofthe character described, in combination, an` elongated guideway mounted upon a mast, or the like, arunner adapted to be attached Vto a sail, and means for attaching said runner to said guideway for movement therealong in opposite directions, said attaching means including a pair of rollers mounted at each side of said runner and engaging said guideway at. laterally spaced parts thereof, said rollers having wide open channels for receiving said guideways and. permitting limited torsional or twisting movement of the runner relatively to the guideway so as to reduce binding and friction.

2. In a device of the character described, in combination, an elon Gated guideway mounted upon a mast, or the li e, and being in theform of a flattened bar having its edge corners rounded, a runner adapted to be attached to a sail, and means for attaching said ruimer to said guideway for movement therealong in opposite directions, said attaching means thickness of the edge of said bar so as to permit limited twisting movement of the runner relatively to the guideway.

11. In a device of the character described, in combination, an elongatedguideway in the form of a flattened bar7 a sail attaching runner, and means for attaching said runner to said guideway for movement therealong in opposite directions, said attaching means including rollers mounted upon said runner and laterally disposed thereon, each of said rollers havin a peri heral channel for re'- ceiving the a jacent ge of said 'bar and said channel being wide open relatively to the thickness of the edge of said bar so as to permit twisting movement of the runner relatively to the guideway, the channels of said rollers having curved Contact surfaces curved transversely of the adjacent edges of the said flattened bar.

In testimony whereof I aix my signature.

PRESCOTT C. WILSON.
