IMPROVEMENT IN MACHINES FOR ENTERING BLlND-SL'ATS- Specification forming part of Letters Patent No. 139,043, dated May 20, 1873; application filed October 30, 1872.

To all whom it may concern:

Be it known that I, JAMES CHURCH, of the city and county of St. Louis and State of Missouri, have invented a certain Improved Machine for Entering Blind-Slats, of which the following is a specification:

My invention consists in a frame having horizontal bars, which are so notched as to hold the slats in the proper position to enter the mortises of the stiles.

Figure 1 is a perspective view, showing one of the machines with a number of the slats in position upon it. Fig. 2 is a longitudinal section through one end of the machine. Fig. 3 is a perspective view, showinga modification.

A B are two similar bars, having their upper surfaces serrated, or having inclined planes or faces a b; the inclines of said planes being similar to the inclines of the mortises c in the blind-stiles for the reception of the blind-slats. G are cross-bars connecting the bars A B together.

In use the machine will be secured to the work table or bench, and the stiles D and connecting cross-bar D placed outside of said machine, one of the cross-bars D abutting against the ends of the bars A B, as indicated in Fig. 2. The slats E are then placed on the inclined planes or faces a b, the lower ends of said slats abutting against the shoulders a b of the bars A B, as indicated in Figs. 1 and 2. The shoulders a b overhang,

so as to hold down the lower edges of the slats E. By forcing the stiles together the slats will be guided into and readily enter the slots or mortises e in the blind-stiles.

In Fig. 3 is shown a modification of the machine, so constructed as to allow for adjustment tosuit larger or smaller sizes of sash and different inclines of blind-slats. To longitudinal bars F is secured a series of adjustable lugs, G, having inclined planes, or faces a and shoulders 11.. Said lugs G are adjusted longitudinally and inclined as desired, and are clamped in position by set-screws g. The slotted portion of the lugs G is preferably rounded, as shown at g, to give a firm bearing on the top of the bar F at all inclinations.

The modification will be used in the same 'manner as the simple form before described.

A weight may be placed on the slats to keep them in position on the inclined faces a b, and against the shoulders a b.

In place of the duplicate bars A B, a single broad bar or ribbed board may be used; but this form would be both more cumbersome and lesseffective than the forms shown, and he obviously a mere modification of the same.

What I claim is- The combination and arrangement of horizontal bars A B with inclined planes or faces a b, shoulders a b, and cross-bar G, as and for the purpose set forth.

JAMES CHURCH.
