SPLINT-HOLDING FRAME To all whom it may concern:

Be it known that I, WILLIAM H. PARKER, of Passaic, Passaic county, New Jersey, have invented a new and useful Improvement in Splint-Holding Frames, of which the following is a full, clear, and exact description.

My invention relates to improvements in splint holding frames such as are used for holding a quantity of match splints the right distance apart and with level ends, preparatory to dipping in the paraffin and firing compositions.

In many factories the so-called German frame,-consisting of a series of wooden slats running freely on rods and with a clamping device to tighten up the slats so as to hold splints inserted between them, is still used because this sort of frame is for many reasons desirable. There are, however, objections to it, chiefly because of the unyielding nature of the slats and because the slats are likely to break off at the ends after a little usage.

The object of my invention is to produce a splint holding frame on practically the lines of the German frame, in which, however, instead of wooden slats, spring slats are used in the form of yielding plates best made by bending the plates so that they will be of a general U shape in cross section, and arranging these slats so as to operate on the slide rods like the ordinary wooden slats. In this way slats are formed between which the splints readily enter if they are pushed between the doubled portions of the spring slats, and moreover, the spring metallic slats such as I here describe are cheaper than the wooden slats, far more durable, and they hold the splints better.

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

Figure 1 is a broken inverted plan view of a section of a frame showing my improved slats. Fig. 2 is a cross section on the line 22 of Fig. 1, and Fig. 3 is a side or edge view of the frame.

Like the German frame referred to, my improved frame has the end pieces 10 and 10 which are connected by the rods 11 arranged at the side of the frame, the rods being fast to the end piece 10, while the end piece 10 slides on the rods. Between these Specification of Letters Patent.

Serial No. 8&,5'71.

end pieces 10 and 10 are arranged the slats for holding the splints, which slats are preferably formed of metallic plates 12 of spring material, which are long enough to extend across the whole width of the frame and are transversely perforated as shown at 13 so that they may slide freely on the rods 11. The plates 12 are preferably formed so as to be of an inverted U shape in cross section being, as stated, doubled upon themselves, and their free edges are therefore quite springy and have a tendency to press snugly against each other. Any desired number of these spring slats can be arranged on a frame, and the tension of them against the splints can be regulated by adjusting the end piece 10*, as is usual in frames of this character.

The edges of the spring slats 12 can be left plain as shown at the top of Fig. 1, or they can be scalloped as shown at 14 in the lower part of the same figure, or they can be slightly slotted or crimped as shown at 15 in Fig. 2. I have shown these several forms of the slats to bring out clearly the idea that the invention is not confined to any special configuration of the slat edges. In practice, however, it is better to have the edges slotted as shown at 15 so as to provide individual spring sections which will grip the individual splints as shown clearly in Fig. 2. In this way the splints are individually held against lateral displacement, that is displacement row-wise. If desired the slots 15 can be placed far enough apart so that two splints can be held between adjacent slots, or even a greater number, but the slats hold better where the parts are slotted so as to form individual grippers for not more than a pair of splints.

It will be observed that by having the slats entirely free on the rods 11, with their bent or doubled portions next the side from which the match splints 16 are inserted, the splints are very easily pushed between the slats by any ordinary mechanism, and they are also very easily pushed out in the same direction that they came in. The slats should be left entirely free and unrestricted, and should notbe reinforced by any rods eX- tending through them, as this has a tendency to restrict the resiliency of the spring and complicate the frame.

It will be seen that the structure which I have described is of the simplest nature, and

that it serves its purpose well of holding the splints 16 in the desired position for dipping.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A splint holding frame comprising slide rods on the sides of the frame, and a series of parallel slats sliding freely on the rods and adapted to be held in close contact, each slat being open at the bottom and with its opposed lower edges yielding in relation to each other.

2. A match frame comprising side rods, a series of transverse slats held in parallel relation and sliding freely on the rods, each slat being open at the bottom and with its opposed lower edges yielding in relation to each other, and means on the rods and at the slat ends to hold the slats in close connection.

3. A splint holding frame comprising a series of parallel spring slats, the slats being formed of spring plates, each plate doubled transversely upon itself so as to leave the edges of the slats free, and means for holding the slats in parallel relation and in close contact.

4. A splint holding frame comprising a series of spring slats each of a general U shape in cross section, the slats being held in parallel relation with their free edges together,

and with the backs of the slats all in the same direction. i

5. A splint holding frame comprising side rods, end pieces on the rods, and a series of spring slats sliding freely on the rods between the end pieces, the slats being of a general U shape in cross section.

6. A splint holding frame comprising a series of spring slats each of a general U shape in cross section, the slats being held in parallel relation, with their free edges adjacent, the said edge portions being slotted transversely to form a series of independent grippers.

7. A splint holding frame comprising side rods and a series of spring slats of a generally inverted U shape sliding on the rods, the slats having their edge portions serrated and formed into individual splint grippers.

8. A splint holding frame comprising a series of spring slats each of a general U shape in cross section, the slats being held in parallel relation and having their opposed free edges formed into a series of splint holding sections.
