ARTIFICIAL HONEYOOHB.

To all whom it may concern:

Be it known that I, HARRY B. DEAN, a citizen of the United States, residin at Upland, in the county of San Bernar ino and State of California, have invented new and useful Improvements in Artificial Honeycombs, of which the following is a specification.

My object is to make an improved honeycomb, and my invention consists of the novel The leading feature of my invention is the construction whereby are integral on alternate sides, and this is accomplished b om a single s eet of meta and fo ding the metal back and forth to make-integral connections so aS to hold the tiers in alinement, and so as to simplify the work of assembling and avoid the liability of displacement.

igure 1 is a fra entary plan view of a sheet of metal showing the result of the first step in roducing a honeycomb in accordance with the rinciples of my invention.

Fi 2 is a Eagmentary plan view of the meta shown in Fig. 1 and showing the result of-the second step in its construction.

Fig. 10 is a view analogous to Fig. .4 and showing the result'of the fourth step of the modification. i

Fig. 11 is a view analogous to Fig. 5 and showing the modified honeycomb.

In producing a honeycomb according to my improved invention I take a. sheet 1 of very thin aluminum and of any desired s1ze large enough to make a plurality of tiers of half cells, and the first step in its construction consists in cutting or slitting the metal Specification of Letters Patent.

upon lines where the metal must be separated in forming the half cells.

In reading from top to bottom in Fig. 1 there is a horlzontal row of

half slits

2, 3, 4 and so on formed from the upper edge of the sheet, a second horizontal row of

slits

5, 6, and so on, a third horizontal row of

sl1ts

8, 9, 10 and so on, a fourth horizontal row of

shts

11, 12, 13 and so zontal row 14, 15, 16 and horizontal row 17, 18,19

In reading from left to 4 and so on are in a line lengthwise of the sl1ts. The slits 5,. 11, 17 and so on are in a lme lengthwise of the slits. The row starting with the slit 5 is between starting with the

slits

2, 3 and so on.

After the sheet has been slit-throughout, as shown in 7 straight bending.

The line 20 extends strai ht cross the sheet at the upper ends of t e s its 5, 6, 7 and so on and at the centers of the slits 2,- 3, 4 and The line 21 is crosswise of the lower ends, of the

slits

2, 3 and 4 and a third of the distance slits 5, 6 and 7. The bond 22 is at the u ends of the slits 8, of the way down slits 5, 6 and 7. The bend ends of the

slits

5, 6 and 7 and one-third of the way down on the

slits

8, 9 and 10. The

bends

20, 21, 22 and 23 form the element of a complete row or tier A of half cells.

In a like manner the metal is bent upon the lines 24 25, 26, 27 and so on to form a second tier 3B of half cells and the metal is bent upon the lines 28, 29, 30 and so on to form a third tierC of half cells.

The third step consists in bending the sheet crosswlse of the

lines

20, 21, 22, 23, 24, 25, 26, 27, 28', 29, 30 and so on thus p ing the

hem

31, 32, 33, 34, 35, 36, 37 and so on of half cells extending crosswise of the tiers A, B, C and so on.

Informing the

tiers

lines

38, 39, 40 and so on and upon the lines 41, 42, 43 and so on. The

lines

38, 39, 40 and so on are in line with the

slits

5, 6, 7 and so on, and-the lines 41, 42, 43 and so on are in line with the

slits

2, 3, 4'and so on.

The fourth step in its construction consists in bending the metal back andforth on the
