Title: Improved method and machine for the blocking of felt hats
IPC: A42C1/04
Filed: 1939-06-13
Abstract: 529,945. Hats. UNITED STATES HAT MACHINERY CORPORATION. June 13, 1939, No. 17240. Convention date, June 20, 1938. [Class 63] A hat blocking and stretching machine comprises a vertically movable hat block, a plurality of grippers adapted to grip the edge of the brim, move outwards to stretch the felt and then inwards to wrap it over the block, and a banding- ring of rubber capable of self-adjustment laterally and vertically to mark the junction line of crown and brim. A block A has an opening 17 to engage, loosely, a pin 22 on a table 20 supported by a piston in a cylinder 26 supplied with steam by a hand operated valve. Around the block are arranged grippers comprising fixed jaws 48 pivoted at 73 and tilted about this pivot by a ring 89 carried by the piston rod of a cylinder 96 also having a handoperated valve. The movable jaw 50 of each gripper is actuated by a second ring 62 moved up and down by a hand-operated eccentric. The outside of the felt hood on the block is steamed from a shower outlet 130 carried by a plunger 108 having a roll 114 engaging a cam slot in a fixed guide 110, the plunger 108 being lowered by a treadle against the action of a spring. A steam shower 135 steams the inside of the felt. Both steam supplies are automatically turned on by collars 126, 149 in the plunger 108, which collars engage control valves as the plunger is depressed by the treadle. In operation, a felt hood is placed over the block A and its edge placed in the grippers which are then closed. Steam is admitted to the cylinder 26, forcing the block upwardly, while the grippers are urged outwardly. A banding ring of rubber, engaged loosely by a hand lever, is then pressed down to the junction of crown and brim and the grippers are swung inwards to wrap the felt over the brim shape, pressure still being maintained in the stretching cylinder 26. Finally, a string is tied at the edge of the brim, in a recess in the block, and the block may be removed. If it is desired to remove the banding ring, a second string may replace this. In a modification, the block A is inverted, and urged downwardly by a handle 156. The banding ring 194 is then carried by posts 192 urged upwardly by springs in guides 190 carried by a plate 186 having lateral play in a steam chamber 180.

The colloidal solution of silicic acid is preferably prepared by mixing a solution of an alkali metal silicate with an acid in such proportions as to leave an excess of acid in the solution, and this colloidal solution is then mixed with the liquid binder to which has been added a sufficient amount of alkaline reagent to neutralize the excess acidity of the colloidal solution, the silica gel being formed when this neutralization takes place. The binder is preferably the latex of a rubber-like substance to which previously has been added sulphur in an amount sufficient for producing the desired rubber-like compound and ammonium hydroxide in an amount sufficient to neutralize the excess acidity of the colloidal solution and to prevent coagulation of the latex, the binder being converted into solid form by coagulating the latex and then vulcanizing.  The composite gel material may be shaped into desired form before the latex is coagulated and the shaped material may be dried after vulcanizing.  Other binders which may be used are emulsified asphalt and phenol-formaldehyde type resins, and a small quantity of cotton linters or other fibrous material may be added to the reaction mixture to hold the mass together during the drying operation.

Filed: 1942-12-31
Abstract: 1 : 3 : 5-Triazine compounds of the general formula <FORM:0573933/IV/1> are prepared by subjecting a compound of the formula <FORM:0573933/IV/2> to the action of a reducing agent selected from the group SO2, H2PO3, Na2S2O4, SnCl2 and phenyl hydrazine.  In the above formul  Y1 and Y2 may be halogen, -NH2, -NHalk, -N-alk2, hydroxy, alkylamino, -NHCH2. CHOH.CH2.OH, or dialkylamino-alkylamino radicals.  A and B may be hydrogen, halogen, -OH, -Oalk, -NHalk, -NH2, -Nalk2 or alkyl radicals, X may be oxygen, dihalides or groups of the formula <FORM:0573933/IV/3> If the reducing agent is SO2 or H2PO3 the reduction is carried out in the presence of hydrochloric and hydriodic acids, and if it is Na2S2O4 the reduction is carried out in the presence of alkali.  Reduction with SO2 or phenylhydrazine leads to compounds containing arsinoxide radicals or dihalogenarsine radicals, while the treatment with stannous chloride, hypophosphorous acid and sodium hydrosulphite leads to the corresponding arsenocompounds.  In examples: (1) 2 : 4-diamino-1 : 3 : 5-triazinyl - (6) - [amino - 3 - oxy - 4 - phenylarsenic acid] is dissolved in hydrochloric acid, sodium iodide is added and SO2 gas is passed through. The hydrochloride of p - [2 : 4 - diamino - 1 : 3 : 5 - triazinyl - (6)]amino - 3 - oxy - 4 - phenylarsindichloride separates out. It may be converted into the corresponding arsinoxide by the action of alkali such as dilute ammonia or sodium bicarbonate; (2) a suspension of 2 : 4-diamino-triazinyl - (6) - [4 - oxy - 3 - amino phenylarsonic acid 1] in hydrochloric acid containing a small amount of hydriodic acid is treated with stannous chloride to give bis 2 : 21-4 : 41-tetraamino-1 : 3 : 5-triazinyl - (6 : 61) - 3 : 31-diamino-4 : 41-dioxyarsenobenzene.  The reduction processes of the present invention may be applied to other arseno-anilino-1 : 3 : 5-triazine compounds such as monochlor-monoamino-arsenoanilino-1 : 3 : 5-triazine, and other arseno-anilino - 1 : 3 : 5 - triazine compounds obtained according to Specification 537,690.  The p-[2-chloro - 4 - amino - 1 : 3 : 5 - triazinyl - (6)] amino - phenyl-arsonic compound obtained in example (2) of Specification 537,690 is treated in hydrochloric acid solution with SO2 to obtain <FORM:0573933/IV/4>
