GLEANINGS IN BfiE CULTURE. 



43S 



This article is written mainly for beginners, ior 

 all of the older heads have establit-lied plans ot one 

 kind or another, which— ahem!— are probablj' any 

 of them better than the above. If so, won't they 

 tell us about them? (i. M. Dooi.itti.k.

THE T TINS. 



THE NEW MACHINE FOR MAKtNO THEM. 



11 EN the T tins were tirst made they 

 were simply two L tins soldered to- 

 gether th us : II in fact, this was 



the only way ii in which they 



conld be constructed with ordinary 

 tinners'' tools. As soon as there was a de- 

 mand for the T super, it became evident 

 that the T's must be made of one piece of 

 tin. However desirable this might be, 

 there was tlie dilhculty of bending the T's 

 out of one piece of tin. We studied on the 

 matter for some time, and finally Mr. I. E. 

 Good, of Nappanee, Ind., said he would sell 

 us the T-tin folder which he had construct- 

 ed. We told him to send it on, partly be- 

 cause we needed just such a machine, and 

 partly because we were curious as to its con- 

 struction. 



Before we describe the machine itself it 

 will be necessary to explain how the T's are 

 bent, and we will therefore refer the reader 

 to the diagrams be- 

 low, all of which 

 are full size. 



THE T TIN AND HOW MADE. 



We first cut out a lot of tin into strips 13i 

 in. long and If in. wide. A quarter-inch 

 fold is made on each side of the tins, as in 

 Fig. 1. While the guage of the folder is set 

 we will fold all the troughs we 

 need. So far, common tinner's 

 tools are equal to the requiie- 

 ments. It is now necessary to 

 bend Fig. 1 at the point y, into 

 Fig. 3. In order to bring the fold , 



to the right place it will be neces- / 



sary to have some sort of a pio- * 



jection. as in Fig. 2. shown by the 

 heavy black line. This projection 

 should be held firmly, for the fold- 

 ing of the tin produces consideia- 

 ble strain. We next want some 

 kind of device whereby we can 

 easily, quickly, and accurately 

 make the foldat y. To illustrate 

 more clearly, we will suppose that 

 we have procured two boards 

 whose double thickness is such 

 that they will slip snugly between 

 the folds in Fig. 1. They should 

 be hinged at y. Now, then, hav- 

 ing the metal projection as in Fig. 2 secured 

 in the luoper position, we simply open the 

 two hinged boards as we would the covers 

 of a book. When nearly half open, the T 



tin will be bent as in Fig. 2 ; finally it as- 

 sumes the form of Fig. 3. 



This is, in fact, precisely the manner in 

 which oui' new T-tiu folder operates, a cut 

 of which we give below. It is lepresented 

 as ill the act of bending a tin which is now 

 bent as in Fig. 2. below. F and (i are two 

 cast-iron frames hinged on the sides, as 

 shown, so as to revolve on the line at A. 

 The lower iron fiame G is also hinged to a 

 piece of plaiik at the opposite side. A 

 strip of heavy strap iron (the purpose of 

 which WMS described and is represented in 

 Fig. 2 by the black line) of the length of the 

 machine is screwed on to the piece of plank 

 upon which the frames rest below A. as 

 shown. It projects just high enough to 

 make a f fold, as illustrated in Fig. 2, and 

 should then be on a level with the crack 

 between the iron frames. 



To operate, grasp the lever shown on the 

 left ; press downward so that the front side 

 of the two frames is raised above the strip 

 of strap iron. Hold the lever down until 

 you can pick up a trough as II, and slip it on 

 to the rabbeted edge, which is just wide 

 enough to allow the trough to fit snugly. 

 Release the hand from the lever, permitting 

 the point A to drop into position. The strap 

 iron is now just right to make the fold at y, 

 Fig. 1. Now with the right hand grasp the 

 handle C. When revolved as in the engrav- 

 ing, the tin A is folded as shown in Fig. 2. 

 While C is revolving, the foot should press 

 on the treadle attached to the rod B, to hold 

 the frame from slipping above the strap 

 iron. When C is revolved to E, the tin is 

 bent into Fig. 3. The lever is now grasped, 

 a downward motion frees the frame from 

 the strap iron, wlien the T tin can be slipped 

 off and thrown upon the pile E. 



The machine friend Good sent us, al- 

 though made of wood, did not differ sub- 

 stantially in principle from the iron one we 

 have just described. We found, however, 

 that where a large quantity of tins is desir- 

 ed, wood is hardly firm enough to stand the 

 strain of folding, hence necessity compelled 



good's t-tin folder, with oun impkovemp:nt. 



us to make one of cast iron, as shown above. 



One who desires to fold T tins sufficient 



for his own use will find the wooden machine 



ample for all his purposes, and we will fur-
