a Claims.

This invention relates to improvements in bee comb foundations, described and. claimed in my copending application, Serial No. 316,424, filed January30, 1940, of which the present application is a continuation in part.

An object of the invention is the provision of an improved anchoring bar for one or more edges of a wax sheet for retaining the edge or edges of the sheet in position within the usual frame constructed for the purpose.

A further object of the invention is the provision of an anchoring bar is compressed upon an edge or edges of a wax sheet and being so constructed that when the usual attaching frictionally engage section of the bar of the frame to which the edge of the sheet is to be attached in order to retain the edge of the sheet in position within the frame.

This invention will be best understood from a consideration of the following detailed description, in view of the accompanying drawing form ing a part of the to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications as define no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing:

Figure 1 is a fragmentary View in elevation of a bee comb foundation showing a sheet of wax attached in position within a frame.

Figure 2 is a vertical section taken along the line 22 of Fig. 1.

Figure 3 is a similar section showing a modified form of the anchoring bar disclosed in Fig. 2.

Referring more particularly to the drawing, It designates an upper bar and i l a lower bar which are connected together by side bars 12, one of which only is shown, and which constitute a frame I3 in which a wax sheet is mounted. The frame I3 is ordinarily suspended by means of lugs 14 which project from the opposite edges and which project beyond the side bars 13 from the opposite ends of the top bar it.

Longitudinal wires it which may be straight or corrugated are embedded in the sheet 15 as are transverse wires I! which may be corrugated or the wires may be straight as shown at It. When the wires are corrugated the corrugations of the wire will follow the contour of the synthetic cells I8 formed in the sheet 15 in a well known manner.

specification; nevertheless, it is ing the U--shaped member it will be The upper bar Iii is rabbeted as shown at 2!] to receive a U-shaped member 21 and securing strip 22, which is held in place by diagonallydisposed nails 23.

Th anchoring bar in this case is generally U-shaDed in formation, having side flanges 25 and 26 located in parallel relation and pinched onto an edge of the sheet l5 around the outer end of the wire ll as shown at 2'1. The inner faces of the flanges 25 and 25 are in contact with the opposite faces of the wax sheet 15.

The outer portion of the U-s-haped member 25 where it approaches the bight portion 28 is bent at an angle to the flanges 25 and 2B. In so bendseen that the flange 2G is sharply bent at 29 while the flange 25 is curved as shown at 30. The pinching of the flange at 29 also causes the ends 21 of the wires 1'! to likewise be pinched. This offsets the bight portion 28 of the U-shaped member. 2| from the vertical planes of the flanges 25 and 26.

When the attaching strip 22 is secured in place by the nails 23 the inner wall of said strip will be forced against the offset bight portion 28 while the flange 25 will be forced into flat contact against a wall of the rabbeted section 20 of the bar 10. In other Words, the anchoring bar 2| is frictionally secured in place in the bar H).

In Fig. 3 a modified form of the anchoring bar is shown at 21c. In this case the U-shaped member generally designated by the numeral 35 has been bent outwardly as shown at 36 and the bight portion 31 is then bent in the opposite direction so that said bight portion faces the wall 38 of the rabbeted portion 26 of the bar It]. The anchoring bar in this case has a flange portion 39 in engagement with the wall 38 of the bar It while the pinched portion 49 engages the inner wall or face 4| of the strip 22. The bight portion 3! of the U-shaped anchoring bar 21a engages the top wall 42 of the rabbeted section 28 of the bar l0.

Thus it will be seen that when the strip 22 is secured in place by nails as shown in Fig. 2, the inner wall 41 of the strip 22 will be forced against the bent portion 48 of the anchoring bar Zia and thus the strip will force the flange 39 in engagement with the wall 38 while the bight portion 31 of the U-shaped anchoring bar would engage the wall 42 of the bar 16. In this Way the anchoring bar would be frictionally engaged at a number of points and would be securely clamped in position within the bar 1 ii. Since the sheet is also secured to the bottom bar I l and stretched comparatively securely in the frame. The wires II have taut, it will be held their ends located within the U-shaped anchoring bar 2| and these ends which extend beyond the sheet l5 project into the anchoring bar and terminate at the inner edge of the bight portion 31. When the anchoring bar is orimped the free ends of the wire I! will likewise be crimped and will be held in place within the anchoring bars.

While the top and bottom edges of the wax sheet are shown as secured in the frame l3 along two edges only, nevertheless all four edges of the sheet may be secured within the adjacent bars of the frame.

We claim:

1. In a comb foundation, a wax sheet having a wire embedded therein, the end of the wire along one edge projecting beyond said edge, and a U-shaped anchoring bar embracing said edge of the sheet and the projecting end of the wire, said anchoring bar being crimped along a line which is intermediate the opposite edges of said bar, the embraced projecting end of the wire being similarly crimped 2. In a comb foundation, a wax sheet having a wire embedded therein, the end of the wire along one edge of said sheet projecting beyond said edge, a U-shaped anchoring bar embracing said edge of the sheet and the projecting end of the wire, said anchoring bar being crimped along a line which is intermediate the opposite edges of said bar, the embraced projecting end of the wire being similarly crimped, one portion of the fiwax sheet is mounted,

bar being laterally offset from one of the flanges of the U-shaped bar.

3. In a comb foundation, a frame in which a one of the bars of the frame being provided with a rabbeted portion, the wax sheet having a wire embedded therein with one end projecting beyond one edge of said sheet, a U-shaped anchoring bar clamped around said edge of the sheet and the projecting end of the wire, and disposed in the rabbeted portion, said anchoring bar being crimped between the opposite longitudinal edges of the bar to provide a lateral offset on said bar, and an attaching strip secured in the rabbeted portion and frictionally engaging the lateral offset, the opposite edge of the sheet being mounted in an adjacent bar of the frame.

4. In a comb foundation, a frame in which a wax sheet is mounted, one of the bars of the frame being provided with a rabbeted portion, the wax sheet having a wire embedded therein with one end projecting beyond one edge of said sheet, a U-shaped anchoring bar clamped around said edge of the sheet and the projecting end of the wire, and disposed in the rabbeted portion, said anchoring bar having a lateral offset, and an attaching strip secured in the rabbeted portion in contact with the offset and forcing the one face of the bar in frictional engagement with a wall of the rabbeted portion, the opposite edge of the sheet being mounted in an adjacent bar of the frame.
