Prior to my invention channels of this type, Fig. 6 is a sectional view at line 6-6 of Fig. 4. which have been extensively used, have had Figs. 7 and 8 are detail views of another modinotches or slots formed therein, to permit bendfled form of core, shown in flat form before bend- 10 ing to conform to the various curvatures, said ing and in side elevation after bending into channotches or slots being formedjin the sides or in nel form. both the sides and bottom of the channel.

Under some conditions it is also necessary to causing any substantial change in cross section.
The action on the corrugations, when the channel is bent in this manner, is substantially as follows.
The corrugations in the bottom 01' the channel will be compressed so that they taper from the side of longer radiusto the side of shorter radius,
and the corrugations in the side of longer radius will be expanded while those in the side of shorter radius will be compressed.
In the form of core a, shown in Figs. 4, 5 and 6 the corrugations b' are extended across the bottom and sides and are terminated at a short distance from the edges of the strip, leaving the edge portions of the sides uncorrugated. Each edge portion is then bent about a reinforcing wire I, headed edges 9' being thereby formed.
The core will be covered with cushioning material in the same manner as that already described with reference to Figs. 1 to 3.
When the channel thus produced is bent, a bending action will take place at the beaded edges and the bottom portion of the channel will be expanded or stretched, causing the corrugations to be somewhat flattened, and this action will be extended into the sides to a decreasing extent, no change in length taking place at the beaded edges, as illustrated in Fig. 5.
The formation and spacin'g'qf the corrugations in this form may also be varied from that shown without substantial eflect on the bending operation and without departing from my invention. In Figs. 7 and 8 a third form of my invention is illustrated, in which corrugations b", similar to those shown in Fig. 2, are formed in each side portion and the bottom portion, but are not extended across the portions connecting the sides.
' this form of core is bent either in the plane ofthe sides, or of the bottom, the action on the corrugations is similar to that already described with reference to the form shown in Figs. 1, 2 and 3. I claim: 1 1. A bendable window glass guide comprising a channel shaped core of continuous flexible sheet metal having corrugations formed therein and extending transversely of the bottom and sides thereof and adapted for compression or expansion according to the stresses placed thereon when the channel is bent, and a cushion for the glass within said core.
2. A bendable window glass guide comprising a channel shaped core of continuous flexible 'sheet metal having corrugations formed therein extending transversely ,of the bottom and sides thereof and terminating at the edges of its sides, said corrugations being adapted for compression or expansion according to the stresses placed thereon when the channel is bent, and a cushion for the glass within said core.
3. A laterally and longitudinally bendable window glass guide comprising a channel shaped core of continuous flexible sheet metal having semi-circularly and reversely curved corrugations formed therein and extending transversely of the bottom and sides thereof, said corrugations being channel is bent.
5. A window glass guide comprising a channel shaped core consisting of a continuous strip'of flexible sheet'metal, both edge portions of which are bent reversely to form beaded edges and having transverse corrugations formed therein extending from points closely adjacent the bead at one edge to the bead at the opposite edge.
6. A window glass guide comprising a channel shaped core consisting of a strip of flexible sheet metal having a reinforcing wire enclosed by the edge portions of its sides and having corrugations formed therein which extend transversely of the sides and bottom and terminate at said edge portions. 7
