As the 40 Figure 1 is a front elevation of a windowstrip moves with the blind, and at the same frame to which my invention is applied, time moves backward, there is nothing more partly in section.

Fig. 4 is an enlarged detail view showagainst the edge of the blind, so as to exert ing the strip in a raised position. sufficient frictional contact to hold the blind A represents grooved pieces of wood of at any desired point. The moment the blind 50 any suitable width and thickness and which is released the pressure of this strip against its edge causes the blind to be held with sufficient force to prevent its moving any farther, and thus doing away with all necessity for stops and fastenings to hold the blind in any desired position.' As the strip moves downward with the blind the cams or wedges leave the slots and force the strip laterally against the edge of the blind, so as to push it over against the grooved strip in the other side of the inner edge of the frame. The wedges are here shown as the cheapest and simplest devices for causing this strip a lateral movement at the same time that it is being moved endwise; but I do not limit myself to this exact device, as other devicessuch as linksmay be used, if so preferred.

In order to release the blind from the trio tional contact of one of these strips, a pin or projection O is secured to the inner side of the strip, and this pin or projection is made to pass over the top of the cam or any other suitable device which, when turned or moved, will cause the strip to rise and the cams or wedges to enter the slots, and thus cause the strip to move out of contactwith the edge of the blind. Various devices may be substituted for this cam, and I do not, therefore, limit my invention to this particular device. If a cam is used, it will have a handle attached to it, which projects through the window-frame, and by the turning of which will either release or raise the strip, as may be desired. If it is desired to have the blind sink downward without any opposition whatever, it is only necessary to move the cam or other device which raises the strip, and then the blind will drop from its own weight all the way down or any desired distance, as may be preferred. These endwise and laterally moving strips are adapted to be used in window-sashes for the purpose of holding the sashes in any desired position, and thus do away with the weights and springs which have heretofore been used for that purpose. These strips when used will also do away with the necessity for the boxes to receive the weights, the guide-rollers, and the ropes, and also render the window-frames much easier to clean and repair. WVhen these strips are used, it is only necessar T to push the blind or the window-sash to one side, and then they can be takenout without the necessity of removing the stop-beads, as is the case with the windows and blinds now'in ordinary use. This renders the cleaning of the window-frames and windows much easier than has heretofore been possible, owing to the fact that the stop-beads had first to be removed, and, if weights were used, to detach them and then prevent their ropes from being drawn through into the boxes.

Having thus described my invention, I claim 7,

1. The. combination of a grooved piece, a sash or blind having its edge made to catch in the groove, an endwise-moving strip, a spring applied to the strip for returning it to position, and means for causing the strip to move laterally at the same time that it is moved endwise, either by the friction of the blind or sash against it or by the action of the spring, substantially as described.

2. The combination of the grooved piece provided with slots, the endwise laterally moving strip placed in the groove, and earns or wedges for catching in the slots, substantially as set forth.

3. The combination of the grooved and slotted piece applied to the inner side of the window-frame, an endwise laterally moving strip provided with means upon its inner side for causing it to move laterally at the same time that it is moved endwise, anda spring for returning the strip to position when left free to move, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
