GUIDED-WIRE SASH-CHAINHQLTTACHING DEVICE.

Application filed March 1S, 1.921.

To all 'whom t may concern:

Be it known that I, JOHN R. REYBURN, of F airfield, Fairfield County, State of Connecticut, have made a new and useful Invention Relating to Coiled-lire Sash-Chain- Attaching Devices, of which the following is a specification, taken in connection with the accompanying drawing', which forms a part of the same.

This invention relates especially to sash chain attaching devices formed of coiled wire and adapted to readily and eciently secure sash chains to window sashes provided with the ordinary chain grooves and securing holes. This application is a continuation in part, that is, it contains subjectmatter taken from my co-pending applications, 95,550, filed May 5, 1916, and 125,641 filed October 14, 1916.

In the accompanying drawings showing in a somewhat diagrammatic way illustrative embodiment-s of this invention,

Figure ll is a perspective view showing one form of the attaching device.

Figure 2 is a side elevation of a sash to which this device has been secured.

Figure 3 is a similar view of another sash and device.

Figure 4 is a perspective view showing another form of attaching device secured to a sash chain and ready for insertion into the sash.

Figure 5 is a side elevation of the sash to which this device has been secured; and

Figure 6 is a perspective view of this form of device on a. somewhat larger scale.

Figure 7 is a view in perspective of a modified form of the device.

The attaching device may be conveniently and effectively formed of coils of wire of galvanized iron or any other suitable material, the wire being of such size and stiffness as to have 'the desired strength and rigidity and also preferably being small enough' so as to readily allow it to pass into the regular sized loops or eyes of the sashr chain on which it is to be used. lt is desirable to provide the attaching device with a radially prpjecting hanger loop having a greater or less length and which may be conveniently formed on the device by sufficiently extending one of its securing menibers of suitable shape to cooperate with the securing hole of the sash and preferably Specification of Letters Patent.

having the coiled form indicated so as to provide an outwardly extending loop adapted 'to cooperate with the sash chain and maintain the desiredconnection therewith both before and after the attaching device is secured to the sash. lt is desirable to have this loop project suiiiciently so that its inner portions form wedging aligning shoulders which are adapted to have wedging engagement with the sides of the usual securing hole in the sash and thus'positively pre vent turning of the device after it has been forcibly inserted as well as preventing its accidental withdrawal from the hole. As indicated in Figures l to 8 this hanger loop l may in some cases have a very considerable radial extension from the coils of the device and the

sides

2 and 3 of this loop preferably tend to spring outward so as to wedge against the sides of the sash groove l5 adjacent the securing hole 10. For this purpose the sides of this loop may be curved outward so as to form the wedging aligning

shoulders

6, 7 adjacent the securing mernbers or coils of the device so that these shoulders tend to wedge themselves into the upper corners 11 of the sash between the securing hole and groove. With this form of loop it is not necessary in all cases that the coils of the device should be of such diameter as vto tightly engage the securing hole in the sash, since as indicated in Figure 2 the coils 1, 8 may be considerably smaller in diameter than this securing hole which allows the at taching device to be effectively used in old sash or in sash in which the securing holes areoversize in which case as illustrated the coils may fit loosely within the hole in which the device is securely retained in position by the action of its wedging aligning' shoulders. lf desired, one or both of the coils may in some cases be formed with a retaining end, such as 9, which may extend downward into depending position so as to engage and be embedded in the lower side of the securing hole when the device is hammered or other* wise forcibly inserted into the same.

lt is of course more desirable,` however, to have the coils of the device of substantially the same size as the securing hole so that, for example, the coils l and 8 lit more tightly within the securing hole l0, as indicated in Figure 3, so that the retaining end coil 8 which is preferably of somewhat larger diameter than the coil l, lits tightly in the hole and positively retains the device in position in connection with the sash aside from the holding or locking engagement secured through the action of the projecting retaining end 9 or the wedging aligning

shoulders

6, 7. In this way the device which may in some cases have its attaching loop project radially to a less extent than indicated, may be conveniently used with different sized sash or sash in which the securing holes and grooves are either oversized or enlarged by wear, and this is in many cases desirable especially in repair and renewal work, since the attaching device automatically accom- Inodates itseli:l to these variations in the size and secures effective holding engagement with the sash regardless ot such ditlerences. To facilitate insertion oi" the device into the eye or loop 13 ot the sash chain 141 the device may be provided with one or more loosely coiled inserting ends, such as 5, this loop or coil being so loosely coiled upon itself that its end is laterally spaced away from the adjacent turn or coil l of the device so that the chain loop may be conveniently run around the same and worked up into the hanger loop, about in the position indicated in Figures 2 and 3. The other coil 8 may7 il desired, be tightly coiled so that each coil or turn thereof is in substantial contact with the adjacent coils so that the accidental disengagement o't the chain is thus prevented, especially when this tightly wound coil 8 is on the outside as the device is inserted in the sash.

Another itorm oi5 the coiled wire attaching device is shown in Figs. el to 6 in which the radially projecting hanger loop. such as 21, my be conveniently :lormed by extending one ot' the coils ot the device su'liciently toprovide an outwardly extending loop adapted to cooperate with the sash chain and maintain the desired angular position oi' the device in connection with the chain both before and after the attaching device is secured in the sash. 1t is desirable to have this loop project sulliciently so that its upper portions 'form wedging aligning shoulders '1(3 which are adapted to have wedging engagement with the sides of the usual securing hole in the sash, and thus positively prevent turning of the device after it has been forcibly inserted. For this reason and to prevent axial movement also some of the coils or the device are preferably made ot' such diameter as to tightly engage the securing` hole in the sash either with or without relation to the wedging action of such a projecting loop or aligning member so as to more securely hold the device in position. For this purpose some of the coils ot the device such as the coiled retaining end 18 may it desired be staggered or formed ot relatively large diameter so as to resiliently and tightly engage the securing hole when forced into the same, and it desired this retaining end 18 may be tightly coiled so that, for instance#the` consecutive convolutions are normally in substantial contact with each other so that the tip 20, 'for instance, which may extend downward into the dependingposition indicated is in substantially tight contact with the adjacent turn oit this retaining end of the device. lf desired also this tip 2O ot the retaining end may project outwardly radially somewhat beyond `the adjacent coil so as to have additional securing action and embed or wedge itself into the side ot the retaining hole when the device is inserted. To facilitate insertion ot the device into the eye or loop 13 of the sash chain 111 the device may be provided with a loosely coiled inserting end 19 i which is also preferably though not necessarily ot somewhat smaller diameter than the retaining end oi' the device. 1n this way as indicated in the drawing the tip 1T oi this loosely coiled inserting end is laterally spaced away from the adjacent coil of the device and may, il desired, have its `upwardly extending end located adjacent the attaching loop 1G.

ln using this form of the device the tip 17 of the inserting end may be inserted into the eye 18 of the sash chain 14 and the device turned to bring the hanger loop 21 into engagement with the chain end so that the device in substantially the position shown in Fig. 4l is ready for insertion into the securing hole 10 ot the sash. lt is preferable to first insert the hanger loop in the securing hole and then to Atorce the coiled body ot' the attaching' device into the hole as by hammering it in so that the aligning shoulders 16 are forced tightly home against the cooperating parts o1" the sash and more or less wedge or embed themselves into the corners 11 formed at the upper part ot this securing` hole where it is intersected by the usual chain lgroove 15. Underthcse conditions the retaining end of the device which is preferably of such diameter as to snugly engage the securing hole is simultaneously forced into tight engagement therewith, the radially projecting se curing tip 20 of this retaining end also tending to embed itself slightly in the wood at the bottom of the securing hole, as shown in Fig. 5. so as to have a further retaining action and tend to minimize accidental disp acenient or working loose of the device under service conditions. This forcible insertion or driving home ot the device inthe securing hole naturally tends to compress the loosely coiled inserting end which is preferably iirst inserted and these coils are thus preferably 1forced together and tend vto be held in closer engagement.

1n Figure 7 1 show a modified form of the device in which the projecting hanger loops are omitted. 1n this form some of the coils,

for instance that indicated by 22, are preferably made of such diameter as to tightly engage the securing hole, and resistance to turning in the hole is created by the tip 2 0, as in the other cases. The remaining coils are of progressively decreasing diameter to facilitate insertion in the hole and the device is secured to a chain by threading it through a link as shown.

This invention has been described in connection with a number of illustrative embodiments, forms, proportions, arrangements, materials and uses, to the details of which disclosure the invention is not of course to be limited, since what is claimed as new1 and What is desired to be secured by Letters Patent is set forth in the appended claims.

l. The coiled Wire attaching device for sash chain having a tightly coiled retaining end coil and having a loosely coiled insert-l ing end coil adapted to be readily inserted in the end of the sash chain, said coils being of such large diameter as to be retained in the securing hole of the sash and being connected by a hanger loop projecting radially from said coils a distance several times as great as the diameter of said coils.

2. The coiled Wire attaching device for sash chain having a coiled retaining portion to be retained in the securing hole of the sash and having a projecting securing tip to embed itself in the sash and a connected hanger loop having a Wedging aligning shoulder adjacent said coiled portion and projecting radially from said coiled portion a distance at least equal to the diameter thereof to enter the chain roove in the sash.
