摘要： A block and tackle window balance includes an extension spring and two blocks of pulleys mounted within a rigid channel. A spring coupling connects a free end of the extension spring to the first block of pulleys. The pulleys of the first block are sized in width to center the spring coupling and the free end of the extension spring within the channel. The second block of pulleys are mounted on an axle that is received in slots formed in the channel. A center portion of the axle guides a pulley cord through the second block for exiting the balance.

摘要： A window balance system for a tilt sash uses a pair of constant force curl springs having curled convolutions carried by sash shoes and free end regions mounted in sash shoe channels above the region of travel of the shoes. The recurl tendency of the springs imparts a lift to the curled spring convolutions, and the shoes transmit the lift to the sash. The springs recurl into the convolutions as the shoes rise and uncurl from the shoes into the shoe channels when the shoes move downward, and neither movement requires the springs to slide frictionally within the shoe channels. Each shoe is preferably formed of two identical halves that are assembled to trap the curl spring along with a cam that locks the shoe when the sash tilts.

摘要： A sash platform for an automatic friction shoe connects to the shoe by means of a curved arm that fits into a correspondingly curved recess molded into the shoe body. An abutment limits the insertion of the curved arm into the shoe and holds a sash support blade at an operating level, and a curved holder surface supports the platform against the downward force of a sash. The shoe connects to a spring or counterbalance element and runs frictionally in a jamb liner channel.

摘要： A jamb liner for a window assembly permits tilt-takeout sashes to be assembled to form a standard window assembly without tilt or takeout capabilities. The liner has an extruded body with a pair of channels for engaging the sashes. The channels are interconnected by two webs. One of the webs forms adjacent portions of sash runs, and the other web forms a bow-shaped spring for urging the channels against the sashes.

摘要： A spring balance for counteracting the weight of heavy window sashes includes both a torsion spring and a tension spring. The two springs are separated by a rigid tube. One end of each spring is connected to an end of the rigid tube. A spiral member engages a follower carried by the other end of the torsion spring and includes a stop along its length for engaging an anchor carried by the other end of the tension spring. The spiral member can be attached by conventional means to a shoe or other connection to the window sash.

摘要： An extruded resin spring cover (12) extending for the full length of a resin jamb liner (10) and divided into vertical halves (14) by a longitudinal slit (15) is involved in a friction system that prevents hop or drop of a sash (13) counterbalanced between jamb liners (10). A counterbalance spring system is arranged within spring cover (12) and connected to a platform (20) that has a narrow width neck (24 or 44) extending through slit (15). A sash support portion (25, 37, or 57) of the platform is pivotally mounted outside the spring cover, and a connector portion (30, 35, or 40) of the platform is connected to the counterbalance spring system within the spring cover. Neck (24 or 44) extending through slit (15) affords the pivotal interconnection between the sash support portion and the connection portion and also contributes a fixed friction load involved in spreading the spring cover halves apart at the slit, in the region of the neck. The rest of the friction load is provided by a friction shoulder (26 or 46) on the connector portion engaging the inside of the spring cover and a friction surface (27, 38, or 58 ) on the sash support portion engaging the outside of the spring cover.

摘要： A lock shoe system for a take-out window having take-out jamb liners (10) uses a pair of fins (22) extending laterally outward from opposite sides (18) of a sash pin slot (16) in the jamb liner for supporting lock shoes (30) that move vertically in lock shoe channels (13 and 14) within the jamb liners. The lock shoes bear against and ride on sash sides (24) of the fins, and the lock shoes have pivotally mounted biter knives (40) that can pivot into biting engagement with a frame side (26) of the fins to lock the shoes vertically in place. Arms (45) of the biter knives are engaged by pins (25) extending from the sash (20) into the slots for holding the knives clear of the fins whenever the sash is in its run. When the sash is removed from jamb liners (10), springs (50) on the lock shoes (30) bias the biter knives (40) into locking position against the force of the counterbalance springs (33), which bias the lock shoes upward.
摘要翻译：一种用于具有取出支柱衬套（10）的取出窗的锁定鞋系统使用一对翅片（22），所述翅片（22）从所述侧板衬板中的窗框销槽（16）的相对侧（18）横向向外延伸，用于支撑在鞋底衬里内的锁鞋通道（13和14）中垂直移动的锁鞋（30）。锁鞋抵靠并骑在翼片的窗扇侧面（24）上，并且锁鞋具有可枢转地安装的刀刀（40），其可以枢转成与翅片的框架侧（26）咬合接合，以将鞋垂直地锁定到位。刀片的臂（45）由从窗扇（20）延伸到插槽中的销（25）接合，以便每当窗扇处于其运行状态时将刀具保持在翅片之外。当从框架衬垫（10）移除窗框时，锁定鞋（30）上的弹簧（50）抵抗平衡弹簧（33）的力将咬刀（40）偏压到锁定位置，该弹簧将锁鞋向上偏置。

摘要： An extruded resin jamb liner (10) has a spring cover (12) with a longitudinal slit (15) in which a platform (20) moves for balancing a sash. Platform (20) is a single piece resin part having a spring connector (30) inside the spring cover, a neck (24) extending through the slit, and a sash support (25) outside the spring cover. The platform also has inside and outside friction surfaces (26 and 27) respectively engaging inward and outward facing surfaces of the spring cover on opposite sides of the slit to provide a load-related frictional resistance against vertical movement of the platform in the slit.

摘要： A fluid resistor with a fluid tight structure including two planar members having a surface of each contacting in close proximity. One of the planar members has a laminated structure including a substrate and at least one thin layer of substantially uniform thickness formed on the substrate. A groove extends through the layer. The groove and the surface of the other planar member define a capilliary passageway of substantially constant depth for restricted fluid flow.
