COLLAR IRONING AND SHAPING MACHINE.

Specification of Letters Patent.

Patented Feb. 20, 1917..

Application filed J uly 3, 1914. Serial No. 848,901.

To all whom it may concern:

Be it known that we, ALBERT CONWAY SMITH and FRANcIs HAROLD SMITH, subjects of the King of Great Britain, residing at 1 Trinity Vicarage road, Hinckley, in the county of Leicester, England, have invented certain new and useful Improvements in Collar Ironing and Shaping Machines, of which the following is a specification.

This invention relates to ironing and shaping machines for double or folded collars, of the kind having a rotary unheated cylindrical annular mandrel, on which the folded collar is placed, after the fold has been damped, with the inside portion of the collar on the inside of the mandrel, and a heated rotating roller, which may be grooved, arranged at the edge of the mandrel and which bears against and irons the fold of the collar.

According to the present invention, a machine of the above described kind is provided with a heated ironing tool which shapes the collar while it is still upon the mandrel.

This ironing tool is arranged behind the fold-ironing roller on the inside of the mandrel, and preferably'consists of a heated curved plate arranged parallel to the inner surface of the mandrel and having its leading edge flared away from the mandrel to facilitate the entry of the collar between the plate and the mandrel.

The collar when ironed on the inside portion only, curls inwardly as the outside portion follows the curvature of the inside portion, whereas if the outside portion alone is ironed the curl would be in the wrong direction, z'. e. outward, and if both the inside and outside portions are ironed their tendencies to curl in opposite directions more or less neutralize one another.

Some double collars have button-hole tabs, the upper edges of which A protrude above the folds of the collars and would become crushed if acted upon by the fold-ironing roller. A guard-plate is therefore ar-.

ranged in front of the roller at a position to be encountered by the protruding portion of such a tab, which latter thereby becomes diverted to one side of, and is not acted upon, by the roller. This diverting plate also constitutes a finger guard for the heated roller.

A roller may be provided'on the outside of the mandrel, for the purpose-of pressing With a grooved fold-ironing roller, the

flange on the outside of the mandrel should be sufliciently remote therefrom not to bear upon and mark the outside of the collar.

An example of a machine according to the present invention is illustrated on the accompanying drawings, in which Figure 1 is a sectional elevation, and

Fig. 2 is a plan.*

a is an unheated cylindrical annular mandrel, rotatably mounted on a vertical spindle b, and provided with a worm-wheel c. This Worm-wheel c is driven by a worm 03, secured on a horizontal shaft 6, on which is a loose driving pulley f. The loose pulley f is connected to the shaft 6, by means of a clutch-piece f on the pulley 7', which enon the shaft c,

A curved ironing-plate m is mounted behind the roller j, on the inside of the man drel a, by means of a stem m sliding in a socket n, secured to the upper end of the spindle b. A spring 11, in the socket a presses the ironing-plate m against the inside of the mandrel a. The plate m is heated by a gas-burner o and its leading edge is flared away from the mandrel a, to facilitate the entry of collars between same.

A freely rotating wooden roller p, pressed by a spring 19 against the mandrel a, is mounted on the outside of the latter behind the heated fold-ironing roller 7'.

A switch-plate g is arranged in the known manner with its edge in close proximitv to the mandrel a, some distance behind the ironing-plate m and wooden roller 79.

A guard-plate r is secured immediately in front of the roller closely above and diagonally across the edge of the mandrela.

The spindle j of the fold-ironing roller j flS driven througha train of spur-wheels and 'pinions s, t, a, by 'a pinionm onthe pulley-" driven'shaft' e. r Y r V The machine-operates as follows The gas burners 7c and obeing alight and heating: the fold-ironing roller 9'' and'the m-V 7 side ironing-plate a collar, the fold of drel a, with the/inside portion of the collar which has been damped for instance by pass ing'sameiover a flattened nozz le'from which steamil'ssues, is placed on the rotating man on thelinside of the mandrel; The collar is carriedfby swimmer-e1 beneath the foldgironing roller 'j', whereby the fold becomes ironed. 'Shouldthe collar'have an upwardly V protruding tab, this is thrust onone side by H r encountering the guard-plate rs'o as not to pass beneath the'roller; On'is'suing from beneathlthe roller j 'the collar'is; carried by themandrelav past theheated ironingplate :m, whereby the inside portion 'of the collar isfiironed between the plate m and the 7 mandrel, and ac'quiresan inward curl, to

v which the outside portion of the collar conforms. At the same time the outside portion same. fAfter this, the collar, carried by the mandrel, encounters the leadlng end of the switch-plate q and, by riding up same, 1s

thrownoff the mandrel; 7
