SPECIFICATION formingpart of Letters Patent No. 580,292, dated April 6, 1897. A li ati fil d November 30,1896- Serial No. 613,909- (No model.)

To all whom it may concern:

Be it known that we, GEORGE I. PARKS and WVILLIAM D. NELSON, of Augusta, in the county of Richmond and State of Georgia, have invented a new and Improved Blind- Slatting Machine, of which the following is a full, clear, and exact description.

This invention relates to machines for slatting either rollingslat blinds or stationaryslat blinds or both at one time; and the ob ject is to provide a machine with which the work may be done with a greater accuracy than can be done by hand and with much greater rapidity, and, further, to so construct a machine that it will slat all rolling slats or stationary slats or one-half of the blind rolling and the other half stationary slats all at one time, and, further, to so construct the machine that it may be adjusted to any sizes of blinds. 1

We will describe a machine embodying our invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indi cat-e corresponding parts in all the views.

Figure 1 is a perspective view of a blindslatting machine embodying our invention. Fig. 2 is an enlarged sectional View on the line 2 2 of Fig. 3. Fig. 3 is an enlarged sectional View on the line 3 3 of Fig. 2. Fig. 4is abottom plan view of a portion of the device. Fig. 5 is a perspective view of aportion of the slatholding device, and Fig. 6 is a perspective view of other slat-holding devices.

The machine comprises a frame 1 of any suitable material and upon which are mounted. frame-clamping dogs 2, one set of dogs being arranged at one side of the frame and the other set of dogs being arranged directly opposite. These several dogs are mounted on bars 3, having a relative movement toward and from each other on the upper side of said frame 1. The movement of said bars 3 is imparted by means of a foot-lever at operating links 5, but as this operating means is common to door and blind clamping machines,

' and therefore not our invention, we do not deem it necessary to more clearly illustrate or describe it. I

Resting on the frame 1 between the opposite sides of the clamping-dogs 2 are slat-supporting plates 6. These slat-supporing plates are made quite thin and at their lower edges are provided with an outwardly-extending flange 7. The two plates 6 are connected together by links 8 and 9, the outer ends of these links 8 and 9 being pivotally connected to the respective plates or to the flanges thereof, and the inner ends of each pair of links are pivotally connected to a central bar 10. By moving this central bar longitudinally it is obvious that the plates 6 may be adjusted toward or from each other to accommodate them to the length of slats designed to be connected with a blind-frame. The pivotal connection of one pair of links 8 and 9 of the central bar 10 may consist of a threaded bolt engaged by a thumb-nut 11, which when forced closely against a link will hold the several parts as adjusted.

Detachably connected to the upper portion of each plate 6 is a series of slat- holding teeth 12 and 13. The slat-holding teeth 12 are designed for supporting rolling slats 14 with one edge extendedupward, and the teeth 13 are designed to hold stationary slats 15. The teeth 12 are each provided in their upper ends with a notch 16, corresponding in depth and contour substantially to one-half the width of the slat 14; but slats can be turned in or out of center and the teeth 12 will have a notch of corresponding depth, and each tooth 13 is inclined on its upper end from one edge to the other, and upon these inclined upper ends the ends of the stationary slats 15 are designed to rest, as indicated in Fig. 2.

As before stated, the slat-holding teeth are removably connected with the plates 6. As here shown, each slat-holding tooth has a shank portion 17, adapted to engage in a pocket, one wall of which is formed by the plates 6, the other wall being formed by a strip 18, secured to said plates and having separating-blocks 19 arranged between it and the plates 6.

It will be seen that the shank portions 17 of the teeth provide shoulder portions at the base of the teeth, and these shoulder portions will rest upon the blocks 19.

In operation the side rails of a blind are placed in the blind-clamp, and the dogs and the clamp will be closed to bring said side rails toward the plates 6. Then as many slats as may be desired for a blind Will be placed in the holding-teeth. The side rails may be blocked up by blocks 20, so that the holes therein Will come directly opposite the tenons on the ends of the blind-slats, or in case stationary slats are employed the bars of course Will be blocked up to bring their mortises in line with the ends of the stationary slats. Then by moving the dogs 2 toward each other it is obvious that the side rails will be moved into engagement with the slats. Of course after this operation the entire blind may be wedged and doweled or pinned at once, and When taken out it is ready for the rabbetingmachine.

We have shown in the drawings the machine as operating with two forms of slats, that is, rolling slats and stationary slats, the stationary slats beingin one panel and the rolling slats in another panel; but it is obvious that the whole blind may consist of either rolling or stationary slats.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A blind-slatting machine, comprising a frame, clamping-dogs movable thereon, slatsupporting plates, means for adjusting and securing said plates one with relation to the other, the said adjusting means consisting of a longitudinally-movable bar, and link connections between the bar and plate and slatholding teeth remo'vably connected with said plates, substantially as specified.

2. A blind-slatting machine, comprising a frame, frame-clamping jaws moving toward each other on said frame, means for moving the same, slat-supporting plates, links pivoted at one end to said plates and at their opposite ends to a central bar, a clamping device for securing the links and plates as adjusted, pockets formed in said plates, teeth adapted at their upper ends to engage slats, and shank portions on said teeth adapted for removable engagement in said pockets, substantially as specified.

3. Ablind-slatting machine, comprising, in combination with a clamping-machine, a pair of plates adjustable toward and from each other, link connections for causing said adj ustments, a bar extended longitudinally of each plate, spacing-blocks between a bar and its plate, and slat-supporting teeth having shank portions adapted to engage in pockets formed by said bars and plates, substantially as specified.
