UNITED STATES PATENT OFF E.
DAVID IV. LLOYD, OF PITTSBURG, PENNSYLVANIA.
SASH-BALANCE.
SPECIFICATION forming part of Letters Patent No. 630,461, dated August 8, 1899.
Application filed July 18, 1898.
To all whom it may concern:
Be it known that I, DAVID W. LLOYD, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented 0r discovered a new and useful Improvement in Sash-Balances, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a face view of a window-sash equipped with my improved balance. Fig. 2 is a cross-section on the line II II of Fig. 1 Fig. 3 is a side view of one of the sashes detached, showing the racks in engagement with the intermediate toothed wheeh Fig. 4 is a perspective view of a sash equipped with the guiding and balancing rack. Fig. 5 is a detail View in perspective of the locking device.
My invention relates to improvements in sash-balancing apparatus, and is designed for the purpose of providing a simple and cheap substitute for the usual weights and cord and which shall be operative to raise and lower the sashes together, thus providing for ventilating-openings at top and bottomsimultaneously.
Referring now to the drawings, 2 3 are the upper and lower sashes, mounted in the usual frame 4. Each sash is provided at the edge with rack-bars 5, which project inwardly and form guides engaged by corresponding spaces on the jamb of the frame, whereby the sashes are kept in alinement, the teeth of such racks being oppositely disposed and extending inwardly. At a medium position and located between the racks in the path of their travel is a toothed wheel 6, mounted on a stud-bolt 7, driven into the side frame, with which the teeth of the rack intermesh. Upon raising the lower sash the upper sash will fall, and vice versa, the weight of each sash balancing the other and by its movement and rotation of the wheel 6 the raising or lowering of either sash will result in movement in opposite directions of both, while an even balance of the weight will be preserved.
I have provided means for locking the wheel 6 at any position, consisting of a pin 8, mounted on the end of an actuating device, as a lever 9, inserted in the side frame and Serial No. 686,239. (No model.)
provided with a turningkey 10, which is preferably made detachable, the end being square and adapted to be inserted in a corresponding socket in the lever. By this means the sashes may be locked in any position and the key withdrawn, thereby preventing opening of the window.
If desired, the racks and pinion may be applied to both sides with good results, although I have found in practice that the single arrangement, as shown, is very eflicient.
My invention will be appreciated especially bythoseaccustomed to the usual sash-Wei ghts, as it is much more simple and easy to operate, while being less liable to get out of order. It is particularly adapted to buildings requiring thorough ventilation and will commend itself to a large class of users of this class of devices. 7
Having described my invention, what I claim is v 1. In a sash-balance the combination of a window-frame, a toothed wheel flush with the surface of the jamb of the frame secured on a pivotal bolt within a recess therein about midway of its height, vertical guiding-channels formed in the jamb above and below such toothed wheel, and toothed rack-bars secured toand projecting from the adjacent edges of the upper and lower sashes, said racks entering the guiding-channels and guided thereby and engaging the gear, a portion of the edges of the sashes extending over the outer surface of the j amb and concealing the racks and gear, substantially as set forth.
2. In a sash-balance, the combination of a window-frame, a toothed wheel flush with the surface of the jamb of the frame secured on a pivotal bolt within a recess therein about midway of its height, vertical guiding-channels formed in the jamb above and below such toothed wheel, and toothed rack-bars secured to and projecting from the adjacent edges of the upper and lower sashes, said racks entering the guiding-channels and guided thereby and engaging the gear, a portion of the edges *of the sashes extending over the outer surface of the jamb and concealing the racks and gear, and a locking device consisting of a horizontally-movable pin mounted on the end of a tilting crank-arm, adapted to engage the teeth of the toothed wheel, and to be operated by a key secured to the crank-arm, substantially as set' forth.
3. In a sash-balancing apparatus consisting of the combination of a window-frame, a toothed wheel flush with the surface of the jamb of the frame secured on a pivotal bolt within a recess therein about midway of its height, vertical guiding-channels formed in i the jamb above and below such toothed wheel, and toothed rack-bars secured to and projecting from the adjacent. edges of the upper and lower sashes, said racks entering the guidingchannels and guided thereby and engaging the gear, a portion of the edges of the sashes extending over the outer surface of the jamb adapted to be thrown to one side or the other.
of its center of gravity in its locking and unlocking position, and a removable key for operating the crank-arm, substantially as set forth.
In testimony whereof I have hereunto set my hand.
DAVID W. LLOYD.
