STAMPING MACHINE.
' Application filed December 4, 1922, Serial No This invention relates to presses and is herein shown as embodied in a machine for stamping or impressing work pieces, such as shoe soles, with identifying symbols.
Sole leather varies appreciably in thick ness and in density or hardness, and in stamping machines that take no' account of these characteristics, symbols impressed on different pieces of work are not uniform-in appearance or depth. An object of this invention is to provide an improved machine for applying uniform impressions to work pieces having varying characteristics especially as to thickness. As a feature of the invention, the work pieces arealways gripped with a uniform pressure between two co-operating pressure members one of which has a preliminary work gripping or measuring movement under spring control there being a subsequent positive movement of said member-for a predetermined distance I 1 to effect an impression of the desired depth. In the illustratedembodiment of the inven- 2 tion, the head has a projecting stud for the objects of the invention will appear from aconsideration of the followingspecification and accompanying drawings ,in which Fig. 1 is aside elevation, with some parts in section, of the machine; 7 I
a Fig. 2 is a detail View of a portion of the driving mechanism. Fig. 3 is a side view of the printing head with some parts'in section.
In the illustrated machine, the printing head is normally in a fixed position so that there is no rapidly moving part directly in front of the operator to distract or oppress him; the main clearance movement-"takes place from below'and the work is pressed.

arm 4 in the forward end of which is a cylindrical opening 6. The printing head comprising a bracket 8 has a vertical trunnion 10 swivelled in theopening 6 and having an extension 12 rotatably mounted in a flanged bushing 14 at the top of the overhanging arm. The extension 12'is threaded at its upper end for'the reception of a hand the printing head may be drawn tightly against a corresponding face on the under side of the overhanging arm. The head is locked in either of two positions by a pin 20 projecting from the head and arranged to engage either one of two openings 22and 24 which are 180 apart on the under side of the'arm. It is apparent that, by turning the hand nut 16, the head can'be made to descend nut 16 by means. of which a flat face 18-on1 untilthe pin 20 slides out of one of the openings after which the head can be turned until the pin registers with the opposite opening. Thereupon by tightening-the hand nut, the head can again ber'aised to a locked position with the symbols on the type inverted. By this means, the symbols can be faced either way at the end of-a comparatively long piece of work. Heretofore, with nonreversible heads, a deep'throat opening below i the overhanging arm has been needed to receive the work Whenthe symbolswere to be inverted. p I, i
There projects from the bracket 8 a horizontal stud 26 on which is'rotatably mounted a plurality of dies in the-form of type wheels 28, The stud, in thelform shown, is arranged to receive three type wheels which are held in place by a hook 32 engaging a recess 30 in the end of the stud, the" hook being formed on a swinginglatch The hook is held in locked position by a .Ispring pressed detent 38-housed in a recess of the. swinging latch. Around the interior of each typewheel is a seriesof notches 40 arranged to be engaged by a spring-pressed locking plunger 42 in a recess of the stud 26. Forturningthe type wheels to select the characters to be printed, a gear wheel i i is fixed to a rod 46 which is slidably and ro-' tatably mounted in a bracket on the head so that the gear canbe slid into engagement turned to select the character desired. In
