STOP AND RUNNER FOR ROLLING BLINDS.

Specification of Letters Patent.

Patented Dec. 16, 1913.

Application filed. May 20, 1913. Serial No. 768,889.

To @ZZ whom may concern Be it known that I, EDWARD CAHILL, a citizen of the United States, residing at New York, in the county and State of New York, have invented certain new and useful Improvements in Stops and Runners for Rolling Blinds, of which the following is a full, clear, and exact specification.

This invention relates to rolling slat blinds o-r doors, and especially to the stops and runners attached to the ends of the slats to prevent relative longitudinal movement of said slats and also to reduce friction in the engagement of the ends of the slats within the channels in which the edges of such blinds or doors run.

One object of the present invention is to provide. a stop and runner of the character described which will reinforce the slat to which it is attached and tend to hold the same in proper shape as well as protectthe end of said slat and prevent it from moving longitudinally with respect to the adjacent slats.

Another object is to further reduce the friction incident to the edges of the blinds or doors running in the channels used for guiding them.

A further object is to positively retain the slats the proper distance apart, thereby producing a more rigid door or blind of this sort.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more specifically set forth in the claims at the end of the description.

1n the accompanying drawings, in which similar reference characters are used throughout the several views to indicate corresponding parts: Figure 1 is a broken front elevation of a rolling blind or door having one of my improved stops and runners attached thereto. Fig. 2 is an end view of the same. Fig. 3 is a sectional view, taken on the line III-111 of Fig. 1. Fig. 4 is a sectional view, taken on the line V-IV of Fig. 1, and Fig. 5 is an inner face view of the stop and runner removed.

Referring more particularly to the drawings, A designates the slats of a rolling blind or door, which slats have interlocking hinge connections B at their edges, and C indicates the stop and runner constructed in accordance with my present invention. As illustrated, the slats are formed and connected as described in my prior application for patent, filed May 9, 1913, Serial No. 766,523, but it will be understood that the improved stop and runner constituting the subject of this application may be employed on various other forms of rolling slat blinds and doors with equal success.

The stop and runner C may be made of suitable metal or other rigid material and is preferably shaped to generally conform to the contour of the ends of the slats to which it is to be attached. rFhus, the curvature, or form and size of said stop and runner may be altered to agree with the shape and size of the ends of the slats of the blind or door on which it is to be used without departing from my invention. In the example shown in the accompanying drawings, the stop and runner comprises a plate having an intermediate portion 1 curved to conform to the shape of the end of the slat to which it is attached, and generally circular end portions 2 adapted to cover the interlocked hinged edges o-f said slat and the adjacent slats above and below it. The intermediate portion of the stop and runner has a projecting lug 3 which is also curved to conform to the shape of the slat and which is secured to said slat by rivets 4; or other suitable fasteners. This lug is preferably arranged at one edge of the intermediate portion of the stop and runner and extends only along the middle part of said intermediate portion. Spaced from said lug and extending parallel thereto is a rib or ridge 5 having its terminals or ends located on the faces of the end portions 2 adjacent to the interlocked hinge connections between the slats. r1`he rib 5 and lug 3 are arranged side by side on the same, the inner, face of the stop and runner, andthe space between them constitutes a recess or groove 6, as best shown in Figs. 4 and 5, adapted to fit over the end of the slat for not only protecting the same but also reinforcing it and preventing the same from fiaring up while the stop and runner is being secured.

rlhe end portions 2 are formed with projecting rounded knobs or protuberances 7 on their outer faces for the purpose of reducing the friction incident to said outer faces of the stops and runners engaging the bases of the guiding channels (not shown). The

edges of said endiportions Qfarealso rounded to reduce the friction due to their engagement with the sides ofthechannels.

It will be observed that when the stop and runner is attached `to the end of one slat, as illustrated, it holds three slats in proper alinement, its end portions 2 overlapping the ends of the neXt slat above and below, so that it is only necessary to attach said stops and runners to alternate slats Ain order to vlock all of the slats vagainst relative longitudinal movement. 'lt will also1loe-noted that the extension of the rib -or ridge ionto the end portions 2, where they terminate adjacent to the interlocking ,connections between they slats, serves to'keep the slats Aa proper distance'apart, thereby making the'blind or door morerigid.

Having thus described nay-invention, what I claim as new and-desire to secure by Letters Patent of the UnitedStates is:

l. The combination lwith a rolling blind composed of slats 'hinged together at their edges, of stops and runnersattached to the ends of alternate slats, said stops and runners each compri-sing an intermediate portion having alug projecting from its Vinner face and secured to one surface'of a Slat,

'and end portions overlapping the hinged edges of the slats, there being a rib formed on the inner face of the intermediate portion side byside with but spaced from the lug, forming a groove toreceive the end of `the slat.

2. The combination `with la rollingblindi composedfof slats hinged together at their edges, of stops and runners attached to the ends of alternate slats, said stops and runners each comprising an intermediate portion secured toa slat and having a flat outer face, and end portions overlapping the hinged edgesof the adjacent slats and havingroundedlrnobs projecting outwardly in the direction ofthe longitudinal axis of the slats, beyond the itlat outer face of the intermediate portion for the purpose specified.

3. The combination with -a rolling blind composed of slats hinged together at their edgesfo'f stops and runners attached vto the ends of alternate slatsfsaid stops and runners each comprising an intermediate portionhaving a lug projecting :from its `inner face and secured to one surface of a slat, and yend portions overlapping the :hinged edges'of theslataftherebeing a lrib formed` Aon Ithe inner face vof the intermediate porition -side by side with but spaced from the Copies of thi?. patent may be obtained for ve -cents each, by addressing the Commissioner of Patents,

Washington, D. C.
