Manufactured by E. EDELMANN & Co. - Chicago IL

"Nested" screwdrivers; the head of the smallest size has two sets of threads corresponding to interior threads in the middle and largest sizes. The patent date appears on an example of an E. EDELMANN "3-in-1" nested screwdriver although the internal construction of that screwdriver does not correspond to this patent's claims. The smallest size slides into the hollow handle of the middle size, which in turn fits into the largest size. The threaded cap fits threads in the middle and large sizes. The overall length is almost 5 3/4 inches. In most EDELMANN nested 3-in-1 screwdrivers, the smallest size is threaded into the internal bore of the next largest size, and the two together slip into the largest, which has a threaded retaining cap. The overall length of those 3-in-1 screwdrivers is given as 3 3/4 inches. A similar structure appears in EDELMANN's 4-in-1 screwdriver and in the company's HAN-D hammer with screwdrivers nested in the handle [see patents D54,162 (U.S.), CA-216,934 (Canada) and GB-142,008 (Great Britain)].

Manufactured by E. EDELMANN & Co. - Chicago IL

Light weight "ball pein" hammer with multiple size nested screwdrivers stored in the handle. Corresponds to British patent GB-142,008 and U.S. Design patent D54,162. Produced as Edelmann's "HAN-D" hammer. The arrangement of the screwdrivers resembles Edelmann's earlier 4-in-1 screwdriver (where the two smallest sizes are "loose" inside the next larger size), and one form of the "Three--in-One" screwdriver. Edelmann also used an alternate arrangement for nested screwdrivers based on 1917 patent no. 1,250,328.

Manufactured by E. EDELMANN & Co. - Chicago IL

Ball-pein hammer with a knurled metal handle; the design seems to show parting lines, so the design may reflect a hammer with nested screwdrivers in the handle. Edelmann received British patent GB-142,008 and Canadian patent CA-216,934 for a hammer with nested screwdrivers stored within its hollow handle. Appears as the HAN-D hammer in a 1920 Edelmann ad. The screwdriver arrangement resembles Edelmann's 4-in-1 screwdriver which had been in production for most of the prior decade. Edelmann also used an alternate arrangement for nested screwdrivers based on 1917 patent no. 1,250,328.
