Pusher Downer

A pusher downer, sometimes referred to as a cord pusher, is a hand tool used during the blocking process to assist in positioning and seating a blocking cord around the base of a hat block. By allowing the hatter to apply controlled pressure to the cord, the tool helps secure the felt against the block while maintaining consistent cord placement around the crown.

What a Pusher Downer Does

A pusher downer serves as an auxiliary tool during blocking by assisting in the placement and seating of the blocking cord around the base of the crown block. By allowing controlled pressure to be applied directly to the cord, the tool helps position it consistently while the felt is secured against the contours of the block.

Unlike the hat block, which establishes the crown’s dimensions and profile, or the blocking cord, which maintains pressure around the base of the crown, the pusher downer does not determine the shape of the finished hat. Its purpose is to assist in positioning the blocking cord as part of the broader blocking system.

The usefulness of a pusher downer becomes more apparent when a blocking cord must be worked evenly around the circumference of the crown. The tool provides a controlled means of applying pressure to the cord while reducing reliance on the fingers alone, particularly during extended blocking operations or when working with firmer felt bodies.

Although pusher downers vary considerably in their design, they all share the same fundamental objective: assisting the accurate positioning and seating of the blocking cord while preserving the geometry established by the hat block.

Pusher Downers & Blocking Systems

A pusher downer functions as one component of the broader blocking system rather than as an independent shaping tool. Its role is to assist in positioning the blocking cord while other tools establish the crown’s geometry, provide support, and create the conditions necessary for successful blocking. Understanding these relationships places the pusher downer within the larger sequence of traditional felt hat making.

The tool works most closely with the blocking cord, helping to position and seat it around the base of the crown after the felt has been drawn over the hat block. The cord maintains pressure against the felt while the block establishes the crown’s dimensions and profile. The pusher downer contributes to this process by providing a controlled means of working the cord into its intended position.

Pusher downers are also closely related to puller downers. Although both tools are employed during blocking, they perform complementary functions. A puller downer assists in drawing the felt over the crown block, whereas a pusher downer assists in positioning and seating the blocking cord that secures the felt against the block. Together, the two tools support different stages of the same operation while leaving the geometry of the finished crown to the hat block itself.

The exact combination of tools employed during blocking varies among workshops according to tradition, preferred methods, and the characteristics of the felt being worked. Regardless of these differences, the pusher downer remains a supporting tool whose purpose is to assist the accurate placement of the blocking cord within the broader blocking system.

Design & Construction

Pusher downers have been produced in a variety of forms, reflecting differences in workshop practice, blocking methods, and individual preference. While their appearance varies considerably, all are designed to provide a controlled means of applying pressure to a blocking cord without relying solely on the fingers.

Traditional examples were commonly fashioned from hardwood because of its durability, ease of shaping, and resistance to repeated workshop use. Modern pusher downers may also be manufactured from engineering plastics, aluminum, or produced through additive manufacturing techniques such as 3D printing. These methods have made specialized blocking tools more readily available while allowing designs to be reproduced, modified, and customized for particular workshop requirements.

The working end of a pusher downer is typically shaped to engage the blocking cord while distributing pressure over an appropriate contact area. Some designs incorporate a groove or rounded recess intended to guide the cord during positioning, while others employ broader or differently contoured working surfaces. The geometry of this contact area influences how the tool interacts with the cord and contributes to the control that can be maintained during blocking.

Although materials and construction methods continue to evolve, the fundamental purpose of the pusher downer remains unchanged. It is designed to improve the controlled application of pressure to the blocking cord while reducing the physical effort required to position and seat the cord around the base of the crown block.

Historical Development

Specialized tools for positioning blocking cords have likely existed in hat-making workshops for many years, yet they are only rarely identified or described in surviving trade literature. Unlike major equipment such as hat blocks or brim flanges, pusher downers appear to have been regarded primarily as practical workshop implements, resulting in comparatively little published documentation concerning their development or standard forms.

Surviving examples and modern workshop practice suggest that pusher downers have been produced in a variety of designs reflecting the preferences of individual hatters and the blocking methods employed within particular workshops. Differences in shape, working surfaces, and construction indicate that these tools evolved to meet practical needs rather than conforming to a single standardized pattern.

Historical terminology also appears to vary. While pusher downer has become a common descriptive name among many modern hat makers, the term cord pusher is also encountered, particularly in connection with contemporary reproductions and digital fabrication files. As additional historical sources become available, the accepted terminology and historical development of these tools may be refined.

Renewed interest in traditional hat making has encouraged the development of modern pusher downers manufactured through additive manufacturing techniques such as 3D printing. These contemporary reproductions preserve the fundamental purpose of the tool while making specialized blocking equipment more accessible to individual hatters and small workshops. Future revisions of this article will incorporate verified information from historical catalogs, patents, workshop manuals, and surviving examples as additional primary sources are identified.

Capabilities & Practical Considerations

A pusher downer is a supporting tool within the blocking process and should not be regarded as the primary determinant of the finished crown. Its function is to assist in positioning and seating the blocking cord, while the hat block establishes the crown’s dimensions, proportions, and overall profile.

The effectiveness of a pusher downer depends upon the interaction between the tool, the blocking cord, and the broader blocking system in which it is employed. Differences in cord diameter, cord material, felt characteristics, and the geometry of the tool’s working surface may all influence how effectively the cord can be positioned and seated around the base of the crown.

Because pusher downers encompass a variety of forms rather than a single standardized design, individual tools may differ in their intended application and performance characteristics. Variations in working groove dimensions, contact surfaces, materials, and ergonomics may make one design more suitable than another for a particular blocking system or cord type.

Pusher downers are therefore best understood as specialized workshop tools that improve control during cord placement rather than as tools that determine the quality of the finished hat. Their value lies in assisting the accurate positioning of the blocking cord while working within the broader blocking system established by the hat block and related equipment.
