lMPROVED MACHlNE FOR MOLDING SHEET-METAL WlNDOW AND DOOR CAPS.
Specification forming part of Letters Patent No. 83,200, dated October 20, 1858.
tions of these standards to the table are such that either can be adjusted laterally, as shown in Fig. 3. f
L, Fig. 1, is a guide, attached to the table. by means of the thumb-screw d, the purpose of which will hereinafter be shown. v
Having thus described the construction and arrangement of the machine, lthe use and practical operation of the same are as follows, viz:
1 As above sai the machinev is for making window and door caps, Snc., forming the molding of the same, and at the same time giving the proper curve or arch to the cap.
As will be seen, the rollers C O referred to are male and female, or companion-rollers, and are of such shape as required for the style of molding for the cap. Other rollers of different style and size may be used, as circumstances may require.
Sheets of metal are cut to the proper length and width, and curve to form one-half or less ofthe arch of the window or door. The outlines of Fig. 5 will represent such a sheet when thus prepared for the rollers. Roller K is now adjusted in relation to rollers O O', as shown in Fig. 3, the longitudinal direction of which coincides with the radial line a, the center of which being at the point a', and its arch or arches the segmental lines b, which are of the same degree of curvature as the outlines of Fig. 5, and which figure they may properly represent.
It will be observed that the rollers O C' are also in a radial line of a circle described from the point a hence the three rollers have one common center.
It will be evident that by the adjustableness of the roller K the machine may be arranged to circles ofdifferent diameters, so that window or door caps of any size and curve required may be made by simply moving one end of the roller K to or from the rollers O C', as indicated by the line c, which will give a quicker curve than line a and when adj usted to the radial line a, much longer curve or arch is obtained than either of the above. rlhe machine, on being properly adjusted for the required curve of the cap, the plate above alluded to is now passed through the rollers from the side shown iu Fig. 1. The outer curve of the plate is made to rest against the guide L,which is so adjusted as to bring its side close To all whom it may concern:
Be it known that we, Josnrn PARKIN and Jnvrns H. SMITH, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Machine for Making Window and Door Caps, Src.; and we 'do hereby declarev that the following is a full and complete description of the same, reference being had to the accompanyin g drawings, making a part of this speciiication, in which- Figure 1 is a side view of the machine; Fig. 2, a view of the opposite side of Fig. 1; Fig. 3, a view of the top; Fig. 4, an end view; Fig. 5, an exhibit of the work; Fig. 6, an end view of Fig. 5; Fig. 7 a detached section.
Like letters of reference refer to like parts in the several views.
In Fig. 1, A represents a table or stand, on which are secured the standards B by means of the fm ger-screws C, projected through the table into the base of the standards, a slot being provided in the table for the admission of the screws, whereby the said standards can be adjusted longitudinally, for a purpose hereinafter shown.
In said standards are journaled the rollers O O' O being secured permanently therein, whereas O' is journaled in blocks D, fitted in slots E of the standards, and lin which they slide upward and downward by the adjustingscrews F, Figs. 1 and 4, the purpose of which will presently be shown.
Gr, Fig. 4, is a spur-wheel keyed to the shaft of the roller O, and by which roller C' is actuated by means of the transfer-wheels H and wheel G', said wheel Gr being keyed to the shaft of roller C. By this arrangement of the four wheels motion is communicated to the upper roller, the wheels H being secured to a jointed adjusting-stay, I, Fig. 3, so that as the roller C' may be removed more or less distant from the lower one, it will still remain engage with the wheels, and therefrom continue to receive motion.
J, Fig. 2, are also standards, and which are secured to the base of standard B by means of bolts and nuts a. ln these standards is journaled the auxiliary roller K, in journalblocks b, Fig. 4, so that said roller can be moved upward and downward in the standards by the adjustingscrews c. The connecth ereby reducing their expense and at the same time producing a much better article. The rollers C Cf, on being put in reverse relation to each other, will produce a corresponding to the bead of the rollers. Now, on turning the rollers by means of the crank A', the plate will be drawn in between them, the outer curve being' held strongly against the guide, thereby guiding the plate in its curvilineal direction through the rollers, from which it receives, by compression and rolling, a transfer ot' the molding, as shown in Fig. 5, an end View ot' which is shown in Fig. 6. j j
To assist in keeping the plate in its proper direction While passing through the rollers, the end, as soon as it leaves them,is engaged by the adjustable roller K, which, being of the same style of molding as the other rollers, re.- ceives the plate upon itself', and thereby guides it along in the direction of the segmental lines Z1, and thus the plate leaves the machine correctly impressed by the rollers, and of a consistent curvature throughout its entire length, as represented in Figs. 5 and 6.
By this means door and Windon7 caps, Sto., can be made up of' two sections only, each reaching from the foot of the arch to the crown, and faultless in its curvature, whereas in the ordinary Way of making them the cap is made up in sections, each section being hammered into shape or struck up with dies and then.v put together by soldering' or otherwise,` a Work Rollers ot' different length may be used by removing the one set and replacing them with others, and adjusting the standards accordingly, so that broad sheets or plates may be passed through the machine if so required.
It will be observed that the rollers and journals are not ers are attached to the journals by dowel-pins f, Fig.` 7, projecting from the ends of the journals, and received into corresponding holes IL, sunk in the ends of the rollers, as indicated by the dotted lines z', Fig. 3.
Vhat We claim as our invention, and desire to secure by Letters Patent, is*
The adjustable auxiliary roller K, rollers C (y, adjustable standards B, and guide L, all combined and arranged to operate in the man ner as and for the purpose set forth.
JOSEPH PARKIN. JAMES H. SMITH.
