and has for its principal obje6t: to provide 7 a curtain stretcher in which simplicity and oheapness of construction, rigidity, adjustability, collapsibility and ease of assembly are combined to generally improve devices of this general character.

Other objects will appear as my invention is more fully explained in the following 7 specification, illustrated in the accompanying drawings and pointed out in the appended claim:

In the drawings, Figure 1 is a plan view of my improved stretcher shown assembled and a fragment of a curtain attached. Fig. 2 is a side view of Fig. 1. Fig. 3 is an en larged cross section of one of the members. Fig. 4 is an enlarged perspective view of clamp. Fig. 5 is a fragmentary view showing one of the end members being assembled within the slot in one of the said members.

Referring more particularly to the drawings, numeral 1 designates side members which are channeled lengthwise and from side to side at one end as at 2. They are also channeled at the other ends as at 3. The ends are cut into the channel 3 by a slot as at 4. End members 5 are adapted to fit snugly in the channels'2 and 3, the former being also slidable lengthwise in the channels 2, the latter filling the channels 3 completely. Thumb screws 6 are adapted to close the slot 4 and thus securely clamp the end member within the channel 3. Clamps 7 are adapted to secure the other end member 5 to the side members 1 so as to form a stiff and rigid rectangle. The clamp 7 is provided with intersecting channels which are located at right angles with respect to each other and which are of such shape as to snugly receive the side members 1 in one of the channels while the end members 5 pass through the other channel as well as through the slot 2 in the side member 1. A thumb screw inthe top of the clamp 7 serves to tighten both the side and end members against the clam The ends of the end members 5 are beveqed as at 5; The

length of an end member 5 is the same as thefch aiinels 2 which are beveled as at 2? so that the end members 5 will fit length wise into the channels 2 and also so that they can he lipped in from one side if the tliesaid Icha1inels, The inner and upper. edges of all of the members are beveled off we Fish 3 and e rmvid tw t 1 1 ispaced hooks 9 throughout their length which are adapted to receive the edge of a curtain 10. When in the knock down position the end members 5 are first entirely separated from the clamp 7 and from the side members 1. The clamps 7 are then moved along the side members 1 until they do not in any way cover the slot 2. The end members are neXt inserted in the slots 2 one in either of the said side members as shown in Fig. 5. The end members 5 are of the same Width as the side members 1 and of the same length as the slots 2, therefore, the end members, when in assembled position, are wholly contained within the side members 1. The clamp 7 is now preferably moved along the side member 1 until it is on that part of side member within which the end member is contained. It will be apparent that the clamp now prevents the end member from being accidentally removed from the slot 2.

It will be understood that my stretchers are free from hinges and that the members are in full length pieces so as to give rigidity and simplicity of assembling. It will be further understood that when collapsed, the end members 5 are placed in the channels 2 and that there are then only two sections to put away and keep track of. It will also be noted that these two sections are in a very simple and compact form and that they are easily reassembled. It willbe understood that each of the end and side members are adjustable with respect to each other, both single and combined, thus forming a stretcher which is adapted to receive many sizes of curtains. The uniform spacing of the hooks 9, the squareness of the angles and rigidity of the stretchers are adapted to stretch curtains uniformly true and square.

While I have shown a particular form of embodiment of my invention, I am aware that many minor changes therein will readily suggest themselves to others skilled in the art without departing from the spirit channel's only and willnot slip clear througha pair of similar and independent one piece side members each having a relatively long longitudinal slottediopening with beveled ends, apair of similar and independent cross pieces with beveled ends, the said cross pieces being of such length and shape asito fit entirely within the said longitudinal slots in the side members when the frame is in the knock down position and to be therein retained frictionally and by cooperating beveled'ends, whereby the entire strctchers are assembled in a knock down position in two independent sections of rigid and compact form, and clamping means, whereby the said cross side members are securely clamped to the said cross pieces when the frame is in the operative position the said cross pieces passing transversely through said clamps, said clamping means including a solid block having intersecting channels Whose center lines lie in the same plane and at right angles to each other.
