]]> US Patent: 261,138 http://www.datamp.org/patents/displayPatent.php?id=55261&pn=261,138 Ticket Punch Patentee: Luther O. Crocker - East Braintree MA Granted:1882-07-18
Manufactured by Luther O. Crocker - East Braintree MA

Improvement on Crocker's earlier patents (nos. 64,286 and 95,091). The improvement is a slot extending into the jaw beyond the pivot point for the stripper plate. This slot helps to align and steady the ticket. A 20th Century McGill ticket punch appears to conform to this patent. 1880s ads for Crocker's Ticket Punch note all three patents; his fourth patent (no. 456,983 granted Aug. 4, 1891) was an additional refinement of this slot.

Manufactured by Luther O. Crocker - Weymouth Landing MA

Improvement on patent no. 64,286. The cutting edge is angled, to make the cutting action easier; the stripper plate is hinged at one end, and fits against coil springs at the other end. This patent along with 64,286 was cited in 1870s ads for Crocker's Ticket Punch. 1880s ads note a third patent (no. 261,138 granted July 18, 1882}).
