"Vintage Machinery" entry for Rowley & Hermance Co.
|
|
Description: |
| An example of this patent is seen in the January 1894 Manning, Maxwell & Moore catalog, page 532. There is no maker's name but the patent date is clearly legible. We found a later version in a 1925 Yates-American catalog and then in a 1905 Y-A catalog where it was labeled as the "R & H Special Heavy Door Clamp". On page 34 of the 1882 Rowley & Hermance catalog is the same artwork as in the MM&M catalog except that the right side casting has the words "LADOW'S PAT. / ROWLEY & HERMANCE MNFRS / WILLIAMSPORT". |
